Exhaust Fans American Coolair exhaust fans MAL Aluminum Exhaust Fans The answer to concerns about rust and corrosion in today s damp greenhouse environment. Combined with an aluminum wall housing, aluminum shutter, and a vinyl coated wire inlet and outlet guards, the AL fan will provide years of trouble-free and corrosionfree service. AL fans feature all-welded angle frame construction for a rugged and durable unit. The fan panel has a deep spun orifice for maximum efficiency. AL fans utilize Coolair s exclusive drive assembly for over 80 years. The die-formed aluminum blades are bolted to a cast aluminum hub, which also serves as the fan pulley. Power is applied through V-belts directly to the propeller with the blade load concentrated directly over the fan bearings, thus eliminating overhung bearing load. AL fans are available with single or two-speed totally enclosed motors.

The slope wall housing allows the shutter to be placed on the intake side of the fan and eliminates the air turbulence that occurs with the shutter on the exhaust side of the fan. It also prevents the warm air from being lost through the metal wall housing to the outside cold air in cold climate conditions Size E F G H J 24 32-3/8 37-11/16 32-11/16 23-7/8 29 1/16 30 38-3/8 44-1/2 38-3/4 23 29 1/16 36 44-3/8 50-5/16 44-13/16 22-1/2 29 9/16 42 50-3/8 56-5/16 50-15/16 21-3/4 29-11/16 48 56-3/8 62-3/8 57 21-5/8 30-1/2 54 62-3/8 68-11/16 63-1/16 22-3/4 32-9/16 60 68-1/4 74-1/4 69-1/8 22-1/4 33 Rough Opening for GSWH & SWHA Housings: Add 1 /2 to E for Width For 2 Wall: Add 3 /4 to G for Height For 4 Wall: Add 1 1 /4 to G for Height For 6 Wall: Add 1 1 /2 to G for Height A AIR FLOW FRONT VIEW 2 E 2 G 2 FRONT VIEW C F D A B AIR FLOW 4 J H SIDE VIEW SIDE VIEW 1 1 /2 G 2 F NBF Powder Coated Steel Exhaust Fans A complete ventilation package that combines the NBF powder coated steel fan with all aluminum shutter (type LRW), a heavy gauge galvanized steel wall housing (square box or slope) and PVC coated wire inlet and outlet guards.

As a general guide, you can use the following system recommendations to insure proper cooling: For 4 pad systems: Use 1 sq ft of pad per 250 CFM For 6 pad systems: Use 1 sq ft of pad per 400 CFM Example: A greenhouse has 6 fans that produce 20,000 CFM each for a total of 120,000 CFM through the house. 4 system: 120,000 250 = 480 sq ft of pad required 6 system: 120,000 400 = 300 sq ft of pad required B evoporative cooling systems 423

Setting The Standard In Evaporative Cooling Media Küül pads are the highest quality rigid cooling media on the martket today. Specifically, Küül pads are constructed with a heavier, virgin quality kraft paper containing a high resin content which provides effective and efficient cooling while giving KüüL pads greater durability, strength and longevity. Küül pads are produced using a unique, patentpending process, ensuring complete resin cure in each sheet of kraft paper. Küül pads are engineered for maximum strength and rigidity through a unique process ensuring complete resin cure using thermal-setting resins for unmatched structural integrity. Kuul pads Black Diamond Edge Coating Increases longevity - most durable edge coating in the marketplace Weatherproof - tough and durable for demanding agricultural applications Pad Durability - Reduces or even eliminates mineral and scale build-up and extends the life of pads Pad Maintenance - Allows pads to be cleaned more vigorously and, as a result, will further resist mineral and algae build-up and accelerated decay Pad Efficiency - Does not restrict water or airflow. While increasing rigidity and durability, Black Diamond Edge Coating allows for the most efficient and effective cooling How to Maximize Pad Life Daily: Visually inspect the pads for bowing and sagging or dry streaks Dry the pads completely every 24 hours Inspect the sump tank, remove any debris and make sure the water level is correct Check the water distribution system for leaks and clogged water distributor holes Weekly: Check bleed-off rate and adjust if necessary Check water flow rate and adjust if necessary Check pumps and clean any debris from the inlet Clean water filter Every 4-6 Weeks (during operating season): Remove and brush pads with a soft bristle brush then flush system to remove debris Drain and disinfect the entire water distribution system General Guidelines A clean water distribution system is the most important aspect for maintaining the entire evaporative cooling system. This, coupled with quarterly inspection/maintenance checks, will ensure a properly operating evaporative cooling system Do not cycle the pump. This will cause the pads to wear out prematurely Use chemicals to clean and disinfect ONLY Only use products that are approved for use with Küül pads Do not use chlorine, bleach or any oxidizing agents PC-1 PC-2 PC-3 Size Number 1-24 25-74 75 & up 4 x 12 x 24 33-3740- $ $ $ 4 x 12 x 36 33-3741- 4 x 12 x 48 33-3742- 4 x 12 x 60 33-3743- 4 x 12 x 72 33-3744- 6 x 12 x 36 33-3745- 6 x 12 x 48 33-3746- 6 x 12 x 60 33-3747- 6 x 12 x 72 33-3748- One Edge Coating * 4 x 12 x 24 33-3749- $ $ $ * 4 x 12 x 36 33-3750- * 4 x 12 x 48 33-3751- * 4 x 12 x 60 33-3752- 4 x 12 x 72 33-3753- 6 x 12 x 36 33-3771- 6 x 12 x 48 33-3772- 6 x 12 x 60 33-3773- 6 x 12 x 72 33-3774- Two Edge Coating 4 x 12 x 24 33-3760- $ $ $ 4 x 12 x 36 33-3761- 4 x 12 x 48 33-3762- 4 x 12 x 60 33-3830- 6 x 12 x 48 33-3767- 6 x 12 x 60 33-3765- *Check for seasonal availability for in stock shipments SHIPPED FOB: Texas Your One Source For Horticultural Information Hummert s Helpful Hints (800) 325-3055 424

FOGCO FOGCO mist systems and misting pumps are fast becoming standard equipment for all greenhouse climate control applications. As an environmental control system, they can have a dramatic effect on greenhouse productivity. Greenhouse productivity is dependent on many factors. A line misting system cannot control or affect all variables, but it can have a positive impact by regulating the temperature, humidity and moisture content within the greenhouse. This capability will promote increased health and productivity within the greenhouse by eliminating plant water stress, one of the most significant factors in the growth of all plants. Plants lose their moisture through evaporation from the leaves. They also gather carbon needed for growth in the form of carbon dioxide through the leaves. By controlling the plants pores through the use of a properly designed misting system, the results are stronger and healthier plants with optimum growth potential. Fog systems can also be used to introduce fertilizers by injecting nutrients directly into the atmosphere. The moisture and the nutrients are absorbed by the leaves of the plant Greenhouse Climate Control These cleanable mist nozzles are available in sizes from.006 to.020 orifice. All cleanable nozzles include an anti drip adapter. This range is available in brass with a stainless steel orifice or an all stainless steel design. Flow rates vary from.01 gpm to.045 gpm with spray patterns from 45 degrees to 85 degrees. Larger orifice sizes and different threads are also available as special order items. fog systems Professional Direct Drive Pump Filter Inlet Filter Bracket Filter Outlet Pressure Regulator Pump Outlet Inlet Solenoid Valve On/Off Switch Oil Drain Plug By-pass Hose Thermal Relief Valve SHIPPED FOB: Arizona Benefits of using greenhouse misting systems are healthy plants, improved propagation and germination processes, reduced energy costs, and more consistent cooling than that provided by conventional fan systems.

TrueLeaf has been innovating greenhouse heating systems for over 20 years. A full spectrum of solutions are available, each one precision engineered for your specific needs. TrueLeaf takes the systems approach to greenhouse projects. They make sure all the diverse systems in a greenhouse work effortlessly together in an integrated way. BioTherm Tubing Roll N Grow for Benches Roll out the heating mat, hook up the fittings and you are ready to go. BioTherm tubing is woven in 2 center spacing, which is optimal for propagation and most general greenhouse bench heating applications. Most growers install this material on the cross members of commercial greenhouse rolling benches before placing expanded metal on top. You can also roll it out on existing growing surfaces of wood or other materials. Set plants directly on the mat, hook up the hot water lines (designed on a custom basis), and enjoy supreme growth and energy efficiency. BioTherm Piping Warm Floor Heating Systems If you are going to pour concrete in any area where plants or people will be, it makes sense to install floor heating. Not only is it one of the most effective methods of heating with the boost to plant growth, it creates a very pleasant working environment. High-Density Polyethylene (HDX) tubing is strong, extremely tough, and very durable. It is made of an ultra-high molecular weight resin and comes in a distinctive red color so you know you are getting true HDX tubing. StarFin BioTherm StarFins tapered six-fin design has three times the surface area of two-fin designs or 51 mm thin-wall steel tubing. This increased surface area produces high heat output, allowing lower water temperatures to be used while producing soft, gentle greenhouse heat. High heat output cuts installation time and labor because fewer pipes are required to meet the heat load. DuoFin DuoFin provides incredibly even heating across the width of your greenhouse growing areas. Its unique tapered fin design delivers a combination of convective and radiant heating quietly and efficiently. Having only two fins means that more loops are needed to meet your heat load, but it also means you will never have to clean debris from the fins. The large inside diameter means less pumping energy is required to provide greater evenness. High Efficiency Boilers and Water Heaters RayPak X-Therm and X-Frye Time-honored technologies unite with cutting edge advancements in RayPak s X-Therm and X-Frye. These provide both the installer and building owner such installation flexibility, ease-of-commissioning, reliability and long-term performance. Both of these are condensing, high-efficiency, small footprints, on-board diagnostic centers and are indoor/outdoor certified. Now is the perfect time to take a closer look at RayPak. Roll N Grow for Floors The BioTherm is woven in on 3 centers, which provides optimum even greenhouse heating for gently warming crops. This product is designed to withstand foot and cart traffic. It s a great, cost effective way to heat any floor area, without having to bring in costly concrete. When installed properly this system can be rolled up when not in use. SunFin BioTherm SunFin is a high-output, radiant heat finned pipe made specifically for various greenhouse heating applications. Manufactured completely from aluminum, BioTherm SunFin pipes do not rust in growing environments. They are lightweight, so they can be stacked as perimeter heating without overloading the structure and hang easily for top heat and snow melt applications. BioTherm SunFin is available in 12 foot lengths, with custom lengths available upon request. Vertical DuoFin The vertical DuoFin is commonly designed to rise as crops grow and using lower water temperature, heat is provided where the plant needs it most instead of heating the greenhouse air. The vertical DuoFin is great for tall crops such as tomatoes and cucumbers. It provides a heated pipe in the crop where flowering and fruiting occur ensuring optimal growth.

Electronic Ballasts use special bulbs. High Pressure Sodium HPS Lamps are the most commonly used lamps in the greenhouse. The spectral emission leans toward the red. HPS lamps have a longer life expectancy than Metal Halide lamps and maintain a high lumen level longer. Super Agro 430-This is used as a standard HPS lamp, but has a 30% increase in the blue spectrum for shorter internodes and will provide an additional 6% more light. Conversion HPS Lamps are meant to be used with a metal halide ballast to provide the High Pressure Sodium spectrum. The NH360 works in a 400 MH ballast and the NH940 operates in the 1000 MH ballast. Sodium to Halide conversions are used in sodium ballasts. Metal Halide MH Lamps are used for thick lush vegetative growth and are used in growth chambers or areas where no sunlight is available. The spectral emission leans toward the blue. MS-Metal Halide Lamps are used as the above MH lamps but must be used in the horizontal position. These bulbs provide more Lumens than conventional MH lamps but may only be used in a system designed to take a MS bulb. This bulb has a tab on the base to fit those designated systems.

PROMOTES UNIFORM AND HEALTHY PLANTS Supplemental light is a must for all bedding plant growers who propagate their own seedlings. When using the Phyto-Lite the grower can be assured of uniform and healthy seedlings. Not weak and spindly, because now you are able to control the amount and duration of light needed, even during the dark-cloudy winter weather. EFFECTIVE PHOTOPERIOD CONTROL Optimum photoperiod for seedling development is 15-16 hours, while optimum light intensity for most seedlings is 300-350 footcandles. The diagram below indicates amount of footcandles at various levels and positions. MORE FOOTCANDLES PER SQUARE FOOT The Phyto-Lite is a real space saver as it allows the grower to produce an enormous amount of seedlings in a relatively small area. For example, when the Phyto-Lite is placed 18 above plant height it has the capacity to produce enough footcandles to cover an area of 45 sq ft or 24 F1020 flats. Propagation Lights Decrease Growing Time & Increase Plant Quality All PHYTO-LITEs come with cord, plug, chain and hanging brackets propagation lighting please note: Because the needs of each grower vary with crop, fluorescent lamps are not included and must be ordered separately. 4 Fluorescent Fixtures Vapor Proof 3 bulb with lens Uses T-8 bulbs Vapor proof design See Page 461-462 for Lamps 2 bulb with lens Uses T-8 bulbs Vapor proof design SPECIFICATIONS: Model 832 Capacity: 8-32 Watt T-8 Fluorescent Lamps (Size 48 ) Size: 2 X 4 X 4 1 2 Deep Weight: 45 Lbs Voltage: 120 Volts Model 1632 Capacity: 16-32 Watt T-8 Fluorescent Lamps (Size 48 ) Size: 2 X 8 X 4 1 2 Deep Weight: 90 Lbs Voltage: 120 Volts 2 x 4 Model 832 47-0840-1 $ 2 x 8 Model 1632 47-0850-1 Truck ship only 8 Vapor Proof Fixtures Made for commercial use with high quality ballast for long life Equipped with energy saving ballast Each fixture is equipped for rapid start and uses 40 watt T-8 lamps Vapor proof models feature an unbreakable polycarbonate lens, ideal for dusty, damp, or wet locations Available in both 2 and 3 tube models Comes with external mounting brackets, 10 cord and plug and pull switch Fluorescent tubes are not included and must be ordered separately An inexpensive lighting system to provide the maximum amount of lighting over a large area The channels require assembly and are ready to be wired into system No cord or plug included Holds four, 32 watt T-8 1 fluorescent lamps (not included) Equipped with energy saving ballast Size: 96 L x 4.5 W x 3.75 H Truck ship only Model V2T8 V3T8 Description 2 Lite Vapor 3 Lite Vapor Wt 7 Lbs 7 Lbs Number 47-0860- 47-0862- PC-1 1-9 $ PC-2 10 & Up $ Model Description 4XT8-VP 4 Tube Vapor Proof Number 47-0832- PC-1 1-9 $ PC-2 10 & Up $ 460

XLS REVOLUX: the patented, industry standard flame retardant material for both energy and shade for greenhouses subject to fire codes like schools, institutions and retail locations. XLS HARMONY REVOLUX: Harmony means light diffusion. Most plants benefit from an even spreading of light which helps avoid hot spots and increases light penetration deeper into the plant canopy. Harmony utilizes white film strips rather than aluminum foils. While not as energy efficient as aluminum, the cooling effect is better and the light passing through the films is completely diffused and widely spread. XLS F HARMONY REVOLUX: a white screen with an open structure for enhanced light diffusion and shading. On warm days it protects, cools, and brings light to the plants from many angles stimulating growth. At night it helps reduce radiated heat loss, minimizing the formation of dew and the risk of fungal diseases. Revolux means flame retardant and is the optimum choice for all installations from a fire safety perspective. Continued on next page 462

Environmental Screens - continued Blackout Cloth XLS OBSCURA FIREBREAK & XLS OBSCURA REVOLUX: consist of a 2 layer blackout cloth for creating short days while saving tremendous amounts of energy. The upper layer is all aluminum for unparalleled heat retention and reflectivity to keep cool when pulled during daylight hours. The under layer blocks light leaks from the upper layer and is available in B/B, black on both sides. Weather Protection LS SOLARWOVEN: a double-laminated, triple layer, woven poly-film product with an anticondensate layer on one side. It has all the advantages of a greenhouse film but with a superior strength and life expectancy. It can also be used as a rolling sidewall or as a retractable roof where cables, fabric keys and hems can be added to finish. Outdoor Shading FLS: an outside screen that protects the crop and controls the climate. During the day, the screen s open structure provides solar reflection and cooling - reducing both greenhouse temperature and plant temperature. At night, it helps reduce radiated heat loss from the plants. Its structure stimulates aluminum and doesn t allow light transmission through the film, making it possible to have a reflective, open shade. FLS can be used for rolling, sliding or fixed screen installations. Are you planning to build? Call our Greenhouse Department!

Kool Ray Liquid Shading Kool Ray Classic Super Concentrated Liquid Shade Back in its Classic Ezy- Off formula, Kool Ray is specifically designed to lower inside greenhouse temperatures during the warmer spring and summer months. Throughout the year, Classic s environmentally friendly ingredients will slowly wear off, allowing for increased light levels as the daylight decreases. Kool Ray is a concentrated formula designed to be diluted with water and works best when applied by spray, but brush or roller may also be used. Standard dilution rate: 1 part Kool Ray to 8 parts water. For a denser shade, several lighter, more diluted coats are recommend over a single, less diluted, heavy coat. After dilution, spray coverage is approximately 1,575 sq ft (175 sq ft/gal). If you desire a longer wear and better adhesion of Kool Ray, just add X-tra Stick. Visor Greenhouse Liquid Shading X-Tra Stick For use with Kool Ray Liquid Shade X-Tra Stick is an adhesive additive for use with Kool Ray that increases adhesion, wear, and overall life of the shade. X-Tra Stick is primarily used when shading glass greenhouses and can be used for plastic but caution should be taken due to the possibility of removal problems. Adhesion rates (per gallon conc.) Light: 4 oz, Medium: 8 oz, and Strong: 12 oz Calculate X-Tra Stick to the corresponding amount of concentrate used before diluting with water. Best to add X-Tra Stick after shade mix has been diluted with water at the desired ratio. Mix thoroughly.

Formulated to perform under the most stressful conditions, this temporary application is safe on all greenhouse-roofing materials including glass, acrylic, and poly. Visor s formulation easily dilutes in water, and allows for quick and easy dissolving once applied. Uniform coverage is best achieved by spraying, although brush and roller application is also possible. Average Reduction: 8 parts water to 1 part Visor Approximate Coverage: After an 8 to 1 reduction, spray coverage is approximately 1575 sq ft liquid shading Sun Clear Sprayable Coating This non-toxic sprayable coating converts the normal hydrophobic (nonwettable) surface of all plastics, glass, and metals to a permanent hydrophilic (wettable) condition. Dripping, which can promote fungus diseases such as Botrytis, is eliminated from the roof of greenhouses and other structures. Up to 50% more light is transmitted through surfaces treated with Sun Clear. When more solar energy is transmitted into a structure, less amounts of energy are required to maintain a temperature.

The result is greater light transmission because the plastic accumulates less dirt. No special equipment is required for application of Sun Clear. Ordinary blower misters or sprayers do the job well. No special treatment of surfaces is necessary. Sun Clear is also completely inert and non-toxic. For plastic surfaces: dilute 100:1; for glass 50:1 A quart will cover 5-10,000 sq ft A gallon will cover 20-40,000 sq ft Thank You We appreciate your business 45-0300-1 2.5 gallon $ 45-0300-2 Case of 2 469
