Products "PeerVent" and "Peerless" Heating and Ventilating Units, for Schools, Hospitals, Libraries, Churches, Dormi tories, Club Rooms, Theaters, Banks, Offices, Auditoriums and other Buildings where many people con gregate. "Peerless" Industrial Heating UNITS (used in place of cast iron radiators), for Factories, Garages and other Industrial Buildings. "PeerVent" and "Peerless" Heating-Ventilating Units This Company makes two types of heat ing and ventilating units--"PeerVent" and "Peerless"--both intended for the same service but differing in design and construction. Only the PeerVent Unit is illustrated in these pages. Information about Peerless Units will be sent on request. boiler tubes are expanded into the tube sheets, and the radiator assembly does not contain a single soldered, welded, brazed or gasketed joint. Test pressure, 150 lb.; operating pressure, 100 lb. Another improvement in the new PeerVent Unit is the noiseless alternating current motor. This motor is of a design which has been developed after years of research and experimentation. It is mounted by means of a specially designed spring suspension, which precludes the possibility of noise caused by the trans mission of phase vibrations. This motor is equipped with an auto-transformer, an integral part of the motor, for providing speed regulation within limits as close as obtainable with direct current motors. This feature saves power, as less current is consumed at low speeds. The new PeerVent motor improve ments are the final step in placing the unit system on a strictly unit basis. The motorgenerator outfit is eliminated. The unit motors operate independently and there is no expense for current except for the unit or units that are actually in service. A single room can be ventilated without the operation of any apparatus other than the PeerVent Unit. There is also a .con siderable saving in the elimination of the first cost and operating cost of the motorgenerator equipment. Features of the Improved "PeerVent" Unit The PeerVent Unit of today has many important improvements, including the new PeerFin radiator. This radiator con sists of two large copper alloy tubes, each surrounded by a series of closely spaced fins, also of copper alloy. The fins are embedded tightly into the tubes, so that under any conditions of expansion and con traction the fins and tubes are in perfect contact and there can be no loss of efficiency in the transfer of heat from tube to fin. The tubes are expanded into malleable iron headers, in the same manner that 634 PeerVent Heating and Ventilating Unit Peerless Unit Ventilation Company, Inc. Heaters, Unit Other improvements in the new Peer Vent Unit include a single-leaf damper which takes the place of the former inter connected fresh air and recirculation dampers, eliminating mechanical linkage. There are no mid-way positions of this damper: either the full volume, of fresh air enters the unit or there is a complete .recirculation of the air in the room. This damper, as well as the mixing damper, has been provided with improved bearings. The mixing damper can be equipped with any type of automatic temperature control. New fan housings have been designed, providing larger discharge capacity at con siderably lower tip speeds. The mixing damper, radiator, motor and fan assembly, base assembly and air filter are all easily removable without the use of tools. The air filter, which is not included as part of the unit equipment, can be of any make preferred and can be installed after the unit has been erected, without any changes in the unit. The filter rests upon supports below the motor and fan assembly, sliding in and out of the unit like the drawer of a desk. With the filter in this position the air is cleaned before it reaches the fans, radiator, etc., and the dirt therefore does not reach these parts. The new PeerVent Unit can be equipped with a positive-action PeerTherm Con trol, which automatically prevents the PeerVent Heating and Ventilating Unit with front removed to ehom interior parts. The fan housings (t) have been improved to provide grater discharge capacity at lower speeds. The air filter (B) is extra eqxripment, not included with the Unit, and can be ofany make specified. The new PeerFin Radiator (3) is an important improvement. This view shows only one of the two rows of dotdy-rpaced fins (tee cross-section below). intake of cold air at any time when the room temperature falls below 65 deg. (or any other predetermined temperature within a range of 15 deg.) Three types of PeerVent Units have now been standardized, and one or another of them will meet practically any archi tectural requirements, including installa tions in existing buildings. Six different types of control have also been standardized, including automatic control throughout, hand control throughout, and various combina tions of hand and automatic regulation.
