Squire-Cogswell/Aeros Instruments, Inc. www.squire-cogswell.com Page 1 Squire-Cogswell/Aeros Instruments, Inc. was formed in 1916 as a supplier of railway and foundry equipment in Chicago. In 1951 the company was purchased by Walter F. Devereux and began to concentrate its efforts on a line of non-lubricated air compressors and vacuum pumps. A niche was found servicing the printing press industry with new and rebuilt pumps. Utilizing this expertise, the company began to supply custom pump packages for various applications. In the early 1950's, Squire-Cogswell/Aeros Instruments, Inc. sold its first hospital vacuum pump package, the cornerstone of today's business and product lines. In 1962 Herbert E. Schifter, Mr. Devereux's son-in-law, became president. The business then grew significantly as a supplier of custom designed and constructed vacuum and air compressor systems for medical and industrial use. To date, Squire-Cogswell/Aeros Instruments, Inc. has manufactured over 15,000 hospital pumping systems that have been installed literally around the world. Today, in the third generation of family ownership by Craig Schifter and his sister, Carol Lewis, the company continues to serve the worldwide needs of hospitals, laboratories, and industrial companies. Squire-Cogswell/Aeros Instruments, Inc. products are distributed through the company's direct sales force and through a network of dealers and distributors. Aeros Instruments, Inc. (now known as Squire-Cogswell/Aeros Instruments, Inc.) is an FDA registered, ISO 13485 certified, UL listed medical device manufacturer. Aeros was formed in 1962 as a wholly owned subsidiary of the Squire-Cogswell Company for the purpose of supplying suction equipment to the medical industry. Aeros now offers multiple models of electric and battery operated suction machines for hospitals, surgicenters, homecare, and EMS applications. Along with its own branded products, Aeros Instruments also manufactures and sells other devices for medical suction and medical gas regulation to other marketing companies on a private labeled, OEM basis. Primary to the Aeros Instruments product mix is the assembly and distribution of suction regulators and flowmeters for one of the largest sellers of such devices in the world. Aeros Instruments and Squire-Cogswell are both regular suppliers to the military and U. S. government. In the 1950's and 60's the companies were located in Chicago, Illinois. In 1969 we constructed a 48,000 square foot building and moved to Northbrook, Illinois. On December 1, 1993, Squire-Cogswell/Aeros Instruments, Inc. began operations in a brand new 84,000+ square foot corporate headquarters along Interstate 94 in Gurnee, Illinois, mid-way between Chicago and Milwaukee.

Most air pressure requirements are for 50 PSIG delivery pressure to facility s main air distribution line. For compressed air pressure requirements of 85 to 130 PSIG delivery pressure, Two-Stage Oil-Less Piston Air Compressors are suggested. Chilled water cooled compressed air after-coolers are available to reduce room heat load/temperature/possibly size of dryers. Air-Cooled and COMBINATION AIR-COOLED / CHILLED WATER COOLED AFTER-COOLER Air Compressor Systems are also available to accommodate particular situations. Oil-Less Scroll Air Compressor Systems are suggested when low noise level is needed close to occupied areas, low vibration is needed close to vibration sensitive instruments/occupied areas, and/or when needed for a small capacity unit at higher delivery pressures up to 130 PSIG. Air-cooled after-coolers are common. Chilled water cooled after-coolers are available to accommodate special situations. LABORATORY VACUUM PUMP SYSTEMS Oil-Sealed Liquid Ring Vacuum Pump Systems are one of the most reliable and low maintenance vacuum sources available. Systems sealed with 10 WT Food Grade Oil (or equivalent) containing anti-wear agents, anti-oxidents, and corrosion inhibitors are tolerant to many corrosive vapors/gasses. Chilled water cooled systems are suggested to reduce room heat load/temperature and to accurately control operating temperature at optimum level. Air-Cooled and COMBINATION AIR-COOLED / CHIILED WATER COOLED Systems are also available to accommodate particular needs. Single-Stage Liquid Ring Vacuum Pumps are used for maintaining design vacuum levels up to 19 to 21 HGV. Two-Stage Liquid Ring Vacuum Pumps should be considered for design vacuum levels greater than 22 HGV. Oil-Lubricated/Recirculated Single-Stage Rotary Vane Vacuum Pump Systems are used for general service when (as a rule) corrosive vapors/gasses and liquids are not present. These are not recommended for low vacuum applications. CHIILED WATER COOLED ASSIST OPTION is used to prolong pump life, extend maintenance intervals, and/or compensate for expected high equipment room temperatures/altitudes. Oil-Less Dry-Running Single-Stage Rotary Vane Vacuum Pump Systems are suggested for mildly corrosive vapors/gasses, and when low to medium vacuum levels are sufficient to service facility. NOTES: 1. GENERAL RULE OF THUMB SIZING CRITERIA FOR TYPICAL MEDIUM SIZED LABS: COMPRESSED AIR --- ¾ SCFM PER OUTLET WITH 50% USAGE FACTOR. VACUUM --- 1.0 SCFM PER OUTLET WITH 50% USAGE FACTOR. Consult factory for other lab sizes and applications. 1. Determination of delivered pressure dew point of compressed air is important for optimal dryer selection. Other vacuum systems are available such as water sealed and recirculated LRVP systems for wet service. 2. CAPACITY SPECS - Air Systems in terms of PSIG & Vacuum Systems as HGV. For performance spec consistency and definition, suggest SCFM capacity basis of 14.7 PSIA, 68F, and 36% R. H. for compressors and 29.92 HGA, 68F, and 50% R.H. for vacuum pumps. 1. Performance levels listed apply to standard barometer conditions. Consult factory for other conditions. 2. Systems meet latest edition of NFPA 99 for Lab Facilities and conform to National Electrical Code. 3. Standard motors are rated for room ambient temperatures up to 104F. 4. Factory (authorized) start-up assistance/in-service training are included in scope of supply. August 31, 2004
Squire-Cogswell/Aeros Instruments, Inc. www.squire-cogswell.com Page 3 LIQUID COOLING IT S BTU-TIFUL! Remember that mechanical room that used to be 75 degrees back when there were only 3 pieces of equipment in the room? Chances are that, as the facility s equipment needs have grown, the ambient temperature of the room has grown right with it. It s well known that heat is a major enemy of mechanical equipment. The good news is that there are effective ways to deal with the problem. Even though all manufacturers of air cooled equipment provide adequate cooling for their own equipment, the cumulative effect of multiple units can have a detrimental effect on the performance and longevity of mechanical, electrical, and electronic components. The use of a facility s chilled water system can greatly assist in the reduction of local heat loads and the extension of component life. For example, on liquid ring vacuum systems the local heat load can be reduced by 25 to 30 BTU s/minute per HP through the use of chilled water. On oil sealed rotary vane systems the heat reduction can average 15 to 20 BTU s /minute per HP. And chilled water aftercoolers on oil-less piston compressors can help remove 15 BTU s /minute per HP. In the case of oil sealed rotary vane systems, the use of a small adapter and liquid to liquid heat exchanger represents an inexpensive addition with substantial benefits. Cooler operation translates into longer service intervals. It is estimated that, for every 15 to 18 degrees F above the maximum rated operating temperature of an oil in a rotary vane pump on clean service, the oil degradation rate doubles. To the extent that the pump is operating on less than clean service (often the case), the maximum operating temperature of the pump s oil will be reduced. Reduction of local heat loads also provides advantages to electrical components. Electric Motors Rule of Thumb is that each 18 degree F rise above the highest allowable stator winding temperature reduces the motor insulation useful life in half. Motor contactors inside electrical panels can also be adversely affected by excessive heat, especially due to short cycling of pumps. The use of minimum run timers and properly sized receivers will help prevent this condition. How much will this heat reduction cost in terms of chilled water? For removing 15 BTU s/minute from either an air compressor or vacuum pump system, the additional load is about 0.085 chiller HP for water-cooled chillers (via cooling towers) and about 0.10 chiller HP for air cooled chillers. The use of chilled water on the systems described can help reduce the air temperature around the systems by 7 to 20 degrees F, depending on type of system. Temperature reduction is based on access space of 2 to 3 feet around systems and ceiling height of 12 feet. Selection Guide / Liquid Cooling
Page 4 To Order Call: 1.800.448.0770 PRINCIPLE OF OPERATION LIQUID RING VACUUM PUMPS www.squire-cogswell.com Figure 1 shows a cross section of a liquid ring vacuum pump. The impeller is cylindrical in shape with a multitude of fins and is located eccentrically in the impeller housing which is partially filled with the sealing liquid, either water or oil. A port plate with suction and discharge openings is located on each side of the impeller cell. As the impeller rotates, the centrifugal force pushes the sealing liquid outward where it forms a liquid ring which follows the contour of the impeller housing. Starting at point "A" the impeller cell is completely filled with the sealing liquid. As the impeller advances, the liquid in the cell recedes and creates a vacuum in the empty space, which draws in the air or gas through the suction port. Continued rotation increases the gas volume in the impeller cell until the end of the suction cycle at point "B". From point "B", the liquid is gradually forced back into the impeller cell, compressing the gas to near atmosphere, until at point "C" the compressed gas is expelled through the discharge port together with a portion of the sealing liquid. The complete cycle can be compared with a piston in a cylinder where the piston is the liquid ring and the impeller cell is the cylinder. The heat generated by the pump during the compression cycle is dissipated into the sealing liquid. The discharged sealing liquid is recirculated back from the separator tank to the pump on Partial Recirculating Systems. Any fresh make-up seal liquid is controlled by the liquid temperature and level switches, reducing consumption of fresh water. Total Recirculating Systems are available in either water sealed or oil sealed configurations, utilizing a heat exchanger, and eliminating the requirement for fresh make-up seal liquid. The heat exchanger removes the heat from the seal liquid before it is re-introduced into the pump. A C B Figure 1

Page 10 To Order Call: 1.800.448.0770 www.squire-cogswell.com PRINCIPLE OF OPERATION ROTARY VANE VACUUM PUMPS The SelecTORR vacuum pump operates as follows: The rotor is mounted on the drive shaft and positioned eccentrically in the cylindrical casing. The rotor has slots for radially sliding vanes, which divide the pump chamber into segments. The centrifugal force of rotation pushes the vanes out of these slots and toward the wall of the casing. As the rotor turns, the gas is drawn through the inlet, compressed and pushed out through the exhaust. In lubricated vacuum pumps, the lubricating oil collects in the bottom of the exhaust oil separator chamber as the gas passes through a demister, then through an exhaust filter, before finally exhausting to the atmosphere.

At the bottom of the stroke the intake valve closes and air is trapped in the cylinder. The air is then compressed in the cylinder and pushed through the discharge valve on the up stroke of the piston. Total compression, from atmospheric pressure to the final discharge pressure, is accomplished in one stroke of the piston.

Page 20 To Order Call: 1.800.448.0770 www.squire-cogswell.com Refrigerated Air Dryers Principal of Operation Compressed air enters the air-to refrigerant heat exchanger (A) where it is cooled by the refrigeration system to the desired dew point temperature. As the air is cooled in the heat exchanger, water vapor condenses into liquid droplets. The air and entrained water droplets then enter the separator (B) where liquid water droplets are removed from the air stream. An automatic drain (C) discharges the collected water from the system. As long as the temperature of the compressed air does not fall below the dew point temperature produced in the dryer, the remaining water vapor will not condense into troublesome liquid in downstream air lines. This dryer fully meets the NFPA 99 requirements for 32 F. Desiccant Air Dryers Principal of Operation A single desiccant dryer consists of two towers, primary and secondary and a instrument panel. This dryer fully meets the NFPA 99 requirement for 32 F. Compressed air enters the bottom of the desiccant dryer where the switching valve directs the compressed air to the primary tower. The up flow drying allows water and heavy contaminates to drop out of the air stream as they enter the tower protecting the desiccant bed from contamination. The air is dried in the tower and directed through a series of check valves and discharged through the outlet. Primary Tower (DRYING) Purge Valve Secondary Tower (REGENERATING) A portion of the dried air is diverted through an adjustable purge valve where it is throttled to near atmospheric pressure and the secondary tower. This dried low-pressure air is called purge air, which regenerates the desiccant in the secondary tower by carrying off the water collected. The purge air is then exhausted to atmosphere through the purge valve and muffler. After regeneration, the purge valve closes and the secondary tower depressurized to line pressure. Inlet Switching Valve Air Inlet Purge Valve An inlet switching valve on the secondary tower then opens and the inlet switch valve on the primary tower closes and the purge valve on the primary tower is opened. The inlet air is now being dried in the secondary tower while the primary tower is being regenerated.
