Hoffman Specialty Co., Inc. Specialties, Healing HOFFMAN MOTO HEATERS Hoffman-Moto-Heaters correct the "upside down" heating results often found in garages, industrial plants and other high ceiling buildings where gravity air circula tion is used. Moto-Heaters distribute the heated air directly in the "working zone" reducing to a minimum the waste heat in the upper areas. The heating element consists of smooth copper fins, 1 Yi in. outside diameter embedded in copper tubing with out the use of solder, forming a three-side metal to metal contact. The tubes are united to steel headers by actual fusion of metal eliminating expanded joints and all danger of leakage. Every heater is tested under 1,000 lb: per sq. in. hydrostatic pressure, and is guaranteed for any operating steam pressure up to 200 lb. per sq. in. Flexibility of output is provided in the Nos. 6, 7 and 8 Moto-Heaters which are equipped with two fans, as follows, 100 per cent total output with both fans running, Front View No. 8, 4 and $ 55 per cent with one fan and 6 per cent with no fans running. Moto-Heaters are made in six sizes and except the No. 2, each size is supplied in three types--suspended, floor mounted recirculating box and horizontal outside air intake box. A selection of three motor speeds, 1750, 1160 and 870 is available depending upon the degree of quiet operation the application demands. Rear View No. 6, 7 and 8 Steam Pressure at Heater--2 Lb. Sq.
