Air System Equipment <Sta^nrfer P.O. Box 577 Far Rockaway, N. Y. TESTS HAVE SHOWN THAT THE "THERM-O-WHEEL" YIELDS 80 PERCENT to 85 PERCENT HEAT TRANSFER EFFICIENCY!! WHAT IS A "THERM O-WHEEL" The Therm-O-Wheel is a rotating cylin der fitted with radial partitions and packed with metal wool which turns con tinually through two separate air streams. The metal wool picks up the heat from one air stream and transfers it to the other air stream. This heat transfer is a continual process, and operates on the principle that beat flows when a temperature difference exists between two air streams. Ideal heat transfer would be taking place if all of the heat from the hot, contaminated air could be transferred to the incoming fresh air. Such complete heat transfer is not practically possible. The Therm-OWheel for the same investment, ap proaches complete heat recovery much more closely than any conventional heat exchanger! Therm-O-Wheel is a rotary heat ex changer specifically designed to effect savings in fuel, power, and equipment when used in heating, ventilating and air-conditioning systems. Therm-O-Wheel is used when an ex haust system is throwing away costly' heated (or cooled) air which has been contaminated by use. When utilized to preheat a fresh air supply, Therm-OWheel transfers heat from the exhaust air stream to the fresh incoming air stream. Similarly, when used for precooling fresh air, the Therm-O-Wheel transfers heat from the incoming fresh air to the exhaust air stream. THERM-O-WHEEL TYPICAL APPLICATIONS Ventilation of schools, offices, printing plants, abrasives manufacturing, plastics manufacturing, welding plants, brewer ies, etc. Therm-O-Wheels are also used in heat recovery for drying kilns, solvent vaporizing ovens and other fuel-fired equipment drawing combustion air from the ambient or directly from outdoors. Another important application is in the ventilation of air-cooled or air-condi tioned rooms, theatres or buildings.
