Air Conditioning Unit Heaters and Coolers Modine Manufacturing Company Heating and Air Conditioning Division General Offices: 17th and Holburn Sts., Racine, Wis. Factories at Racine, Wis. and La Porte, Ind. Branches in all Principal Cities MODINE UNIT HEATERS Front View Bock View HORIZONTAL DELIVERY MODELS Condenser--Copper and copper alloy, inlet to outlet, for maximum resistance to internal and externa! corrosion. Pure copper fins are metallically bonded to round, seamless, heavy-gauge red brass tubes for permanent contact and to insure uninterrupted heat conduction from pri mary to secondary surface. Modinepatented expansion bend permits tubes to expand or contract individually as tem perature requires. All steam and con densate carrying passages are brazed into an integral pressure-resisting unit. Direct - Pipe - Suspension -- Modine patented feature permits suspending unit directly from supply line without additional' time and labor wasting supports; also permits complete rotation of unit for redirection of air stream. Bonderized Casing--Casing protected from rust by Parker Bonderizing. Safety Fan Guard--Staunch, steel' safeguard built into unit protects against danger of unshielded fan. CAPACITIES AND DIMENSIONS Bottom View Condenser--All copper and copper alloy. Tubes are seamless red brass. Headers, inlet and outlet connections are heavy-walled copper pipes. Fins are pure copper. Brazing of all steam carrying passages and metallic bonding of fins to tubes insures rugged unit and continuously excellent heatinga Hollow-square con denser literally grows as it heats up; re treats to normal size as it cools with com plete distribution of stresses and absence of strains where injury might result. Parallel alignment of fins reduces pos sibility of dirt lodging between fins and clogging condenser. Cone-Jet Deflectors--Verticals are regularly equipped with radial or spoke like deflector assemblies illustrated above. Individually adjustable deflector blades make possible delivery of high, narrow jet like cone of heated air from high elevation ... or low, broad, softened-velocity cone from low elevation. TrunCone Deflectors--Verticals can be furnished with special deflectors for use on units mounted at heights lower than recommended for Cone-Jet Deflectors.

Con denser is pure cop per and copper alloy, inlet to out let, for resistance to corrosion, dura bility, light weight and high heat trans fer. "Floating" condenser construc tion provides safe expansion and con traction. Fins are metallically bonded to tubes to prevent corrosion from re ducing heat transfer capacity. Die formed fins promote greater heat transfer; permit use of smaller, lighter coils. Modine design permits use of ducts having cross-sectional areas no greater than those of condenser face. Wide range of capacities and sizes available in Stand ard and Booster Unit types. STEAM DISTRIBUTION TYPE BLAST HEATERS Cross-section supply end, showing double tube construction These coils are characterized by the uniform distri^ bution of. steam throughout entire heating surface . . . even when steam is partially throttled to meet system tem perature demands. Inserted in each con denser tube is a steam-distributing tube with small, accurately-sized and spaced orifices along its entire length. Steam entering distributing tube is uniformly rationed through orifices into external or condenser tube . . . then flows as con densate into return header. Uniform steam distribution minimizes tendency of condensate freezing and tube damage; eliminates need for preheaters or tem pering coils, thus simplifying system design and control; eliminates air stream strati fication. Designed for heating offices, lobbies, corridors, etc. . . . wherever quick, posi tive distribution of heat combined with quiet operation and gentle air move ment are desirable. Has considerably greater heat output than convector of equivalent size. Employs cop per heating coil for use on steam or hot water system. Mounted on wall or ceiling. Capacities: 105 Edr. and 310 and 450 Edr. CONVECTOR RADIATION Built to meet modern residential, institutional, and commercial heating requirements, Modine convectors operate on the principle of natural convection. Cooler, heavier air is drawn in through the enclosure's bottom opening; comes in contact with copper heating unit that carries steam or hot water. As air is heated, it rises; is then circulated out into, room through grille at top of enclosure. Conceated copper heating unit combines compactness with high heat capacity--to give room added floor space as well as fast, even heating. Use of copper makes the heating unit almost instantly respon sive to automatic control. Enclosures are streamlined for simplicity and harmonize readily with any type of interior. Parker-Bonderized before being prime painted, the enclosures are less , vulnerable to the formation and spread of rust. . Manually installed enclosure fronts can be installed in 30 seconds without tools. Easy removal of fronts assures convenience in cleaning and gives ready access to the heating unit. Available in recessed and cabinet types. 989
