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 HORIZONTAL DELIVERY MODELS Available with either steel or copper condensers. WPB Order restricts the use of copper condensers to shipboard ap plication. Steel Condenser--Heavy cylindrical steel tubes and headers are brazed into integral, pressure-resisting units. Steel fins permanently bonded to tubes with metal. Entire condenser assembly is given protective lead-alloy coating to reduce corrosion hazard. Expansion provided for by floating lower header, heavy tubes and parallel heavy brazing. 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 ru$fc by Parker Bonderizing. Safety' Fan Guard--Staunch, steel safeguard built into unit protects against danger of unshielded fan.

Heavy steel tubes and headers brazed into rugged unit of steam carrying pas sages. Steel fins metallically bonded to tubes. Entire condenser coated with lead alloy for protection against corrosion. Square shape of condenser provides uni form distribution of expansion stresses and absence of strain at points where injury might result. Parallel alignment of fins reduces possibility 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.

AH steel con struction. Extra heavy tubes brazed to headers. Fins metallically bonded to tubes. Entire steel condenser coated with corro sion-resistant lead alloy. Casing Parker-Bonderized for rust protection. Modine design stresses structural strength, light weight and highly effective heat transfer capacity with the ability to handle large volumes of air at lower-thanaverage static pressure losses. Wide range of sizes and types available makes it pos sible to meet practically any temperature, air movement and size requirement. CABINET UNIT HEATERS 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 steel heating coil for use on steam or hot water sys tem. Mounted on wall or ceil ing.

Ventilation Heaters-- Standardized STEAM DISTRIBUTION TYPE BLAST HEATERS Navy and Com mercial Marine types in pre heater and re heater design. Extensively used on U. S. Navy and Mari time Commis sion ships. All copper condensers. Shock- proof construction. Protected against salt air corrosion. Variety of sizes and fin spacings available. Navy type in ac cordance with latest Bureau of Ships This line of steel coils is characterized by General Type Plan. the uniform distribution of steam through out the entire heating surface . . . even when steam is partially throttled to meet system temperature demands. Inserted in each condenser tube is a steam-distributing tube having small, accurately sized and spaced orifices along its entire length. Steam entering the distributing tube is uniformly rationed through the orifices into the external or condenser tube . . . then flows as condensate into the return header. Uniform steam distribution provides a safeguard against freezing of condensate and tube damage, eliminating the need Convectors--Standardized Navy and Commercial Marine types. In wide use aboard Navy and Maritime Com mission ships. AH copper heating unit. Enclosures are light weight, but struct urally strong and built for rugged sea going service. Navy type (illustrated) in accordance with latest Bureau of Ships General Type Plan and available for immediate delivery. Technical Bul for preheaters or tempering coils. In letins on complete addition to thus simplifying system design and control, uniform steam distribution solves the problem of stratification in the heated air stream. line of Marine heat ing equipment sup plied on request. . 927
