2 The Global Leader In Heat Exchange Technology With seven decades of experience and commitment to total client satisfaction, Guntner has earned a reputation as the global leader in heat exchange technology. Supported by the best R&D engineers in the business, cutting-edge technology, and eight manufacturing facilities around the world, Guntner continues to break new ground in the demanding market of finned heat exchangers for industrial refrigeration, HVAC, and process cooling applications. Our high standards and dedication to society and the environment around us have earned us the respect of the industry, and the privilege of long-term relationships with our customers around the world. keep(s) your quality keep(s) your quality.

3 The Guntner Product Calculator MPC With the Guntner product calculator MPC, we are able to offer you more than just an overview of prices or the complete product range. This thermodynamic selection program enables you to calculate your own tailored selections based on precise and actual thermodynamics rather than factors or multipliers. A team of experts stand by to guide you through the selection process. Guntner Product Calculator The program can be updated via the internet ensuring that you always have the most exact and precise information for proper selection. We recommend using Guntner s Product Calculator for exact thermodynamic calculations. Varying conditions such as refrigerants, humidity levels and material combinations are all taken into account by the software to most accurately select products to fit your specific needs. > > calculations made easy with our precise MPC software keep(s) your quality. 1

4 Standard Features of Construction Casing: The casing is corrosion resistant Aluminum (AIMg3) and seawater resistant up to fan diameter 20 (500 mm). From fan diameter 26 (650 mm) and larger, the casing is treated and painted corrosion resistant galvanized steel. All casings are powder coated - color RAL 9003 (Signal White) and suitable for all stringent food industry applications. Construction detail takes accessibility into account and does not allow for tight spots. All parts are easily accessible for service and cleaning purposes. Fan orifices are optimized by the manufacturer to ensure maximum efficiency, air throw and airflow. All fans are individually compartmented within complete tube sheets. All hangers and fittings used for construction and assembly are manufactured from stainless steel 304. Products have easily removable side panels for access to internal and electrical components. Tray: All models have corrosion resistant light weight Aluminum (AlMg3) and are seawater resistant. Trays are powder coated color RAL 9003 (Signal White). All trays are our unique fold down type and can be either folded down or completely removed, if required, for for cleaning purposes. The sloped design of the tray ensures maximum and efficient drainage during defrost cycle. Drain outlet connection can be either 2 x 1 1/4 NPT or 2 x 3/4 NPT. 2 keep(s) your quality.

5 Tube: All tubing, headers and connections are manufactured from the highest quality 304 stainless steel 5/8 (15mm) tubing. Parallel, in-line, x (50 x 50mm) allows the reduced air-side pressure to drop through the coil. Tubes are mechanically expanded to ensure mechanical bonding coupled with the best heat transfer efficiency ratio from fin to tube. Our proven floating coil with support tubes does not permit the refrigerant carrying tubes to come into contact with the tube/end plates, and eliminates the risk of tube failure at the tube end plates. All coils are pressure tested to 450 psig with dry air under water, and shipped with a holding charge. Fins: Aluminum fins with a corrugated pattern provide enhanced air turbulence, guaranteeing contact with all surface areas within the coil bundle. 100% drawn die formed finned collars are standard and result in accurate fin spacings of 6.3, 3.6 and 2.5 FPI (4, 7 and 10 mm). All fins are manufactured with a continuous fin sheet in order to reduce the risk of frost build up, air-side pressure drops, dust, dirt and bacteria - simplifying any cleaning procedure. Coil Circuiting: Each unit is specifically circuited to optimize coil performance and capacity with a low pressure drop (consult with selection software to obtain best circuiting for each application). Horizontal headers are standard for re-circulated and flooded applications. Coil connections are manufactured from 304 stainless steel in accordance with ASME B31.5 requirements. Fans & Motors: External rotor axial fans are standard for the entire range. Internal motor thermo contacts must be incorporated into the control circuit for motor protection. All motors are aluminum die cast and of the highest efficiency. They are also maintenance free with guaranteed long life and low noise levels. Fan guards are galvanized steel and PVC coated. All motors are of the blow through type. Standard voltages are 230V and 460V for 3~ / 60Hz applications and 400V for 3~ / 50Hz applications. Defrost: Standard defrost options for all units include air, electric or hot gas. Electric heater elements are stainless steel sheathed and fit directly into tubes within the coil bundle to provide enhanced heat transfer during the defrost cycle. Elements are held in place with clips to prevent them from moving during transport or operation. Electrical: All fan motors are factory wired to the junction box with single point connection. However, factory installed jumpers can be removed for individual / capacity control. All heater wiring is terminated within a junction box for quick and simple field connections. When heater circuit amperages exceed 48 amps, multiple circuits are provided in order to comply with the NEC limitation of 48 amps per circuit. Delivery & Packing: All units are crated and shipped in a position to help facilitate installation. keep(s) your quality. 3

6 Optional Features Construction Materials The entire casing unit, tube sheets and tray manufactured with either 304 or 316 stainless steel. Insulated pan (required by the USDA for certain food / processing applications). Insulated fan panel. Epoxy coated aluminum or stainless steel (304 or 316) fins. Units are supplied standard with carbon steel black pipe connections but can be ordered with either stainless steel pipe, flanges (ANSI B16.5) or carbon steel threaded connection (ASME B1.20). Re-heat coils separated from the cooling coil by means of an air gap. Foot mounts for floor mounting. For unit operation below -40ºF consult sales office. Fans and Motors Oversize motors for higher face velocities and / or external pressures. Defrost Options The use of fan ring heaters is recommended for low temperature applications available in 230 and 460V). For electric defrost - defrost termination and fan delay thermostat factory fitted. Heater limit thermostat fitted and pre-wired. Factory installed check valve between tray and coil for hot gas defrost. Electrical No wiring. All motors wired to common / individual non-fused disconnect. All motors wired to common fused disconnect with thermal protection for each motor. All motors wired to fused disconnect with single starter and thermal protection for each motor. Various wiring options are available please consult with factory for an alternative to suit your specific requirements. Two speed, high efficiency or explosion proof motors. Draw through option on some models (down blow). 4 keep(s) your quality.
