FEATURES
BROAD RANGE OF APPLICATION
• Hot water or steam ROSEMEX unit heaters provide eco-
nomical ‘‘space comfort’’ for industrial, commercial and insti-
tutional applications.
• Horizontal models H and HS in 13 sizes; up to 492 MBH.
• Vertical models V and VS in 13 sizes; up to 685 MBH.
• Greater throw with ‘‘low outlet temperature» HS and VS units
(with high pressure steam).
• Maximum flexibility of air distribution with optional diffuser
arrangements.
• Units with special coil available on request: copper fins on
copper tubes, steel fins on either steel, Bundyweld steel
(copper plated steel), copper or red brass tubes.
APPEARANCE
• Compact and attractive. Modern design enhanced by alu-
minium semi-gloss finish.
HIGH PERFORMANCE
• More CFM for lower outlet air temperature.
• Quieter operation with lower RPM motors.
• Greater air throw and circulation.
• Top opening on V models helps recover warm air at ceiling.
• Suitable for higher temperature drops.
• HS and VS units have wider fin spacing allowing for higher
CFM and higher outlet velocities for even greater throw.
• Accurately rated in accordance with AMCA bulletins # 20
and 22.
• Guaranteed to be free from defects in material or workman-
ship for a period of one year from date of purchase.
RUGGED ‘‘LONG-LIFE’’ CONSTRUCTION
• Casing: die formed, reinforced steel.
• Finish: sheet metal chemically degreased, phosphatized and
etched. Semi-gloss ‘‘grey’’ paint finish.
• Coil: steel pipe headers, copper tubes, ribbed aluminum
plate fins. Red brass tubes, heavy 0.035’’ wall is standard on
HS and VS models, optional on all other models, and
recommended for steam over 5 PSIG. All coils tested with
200 PSIG air pressure under water.
• Motors: specially selected and tested; thermally protected;
permanently lubricated for a minimum of 20,000 hours on H
and HS models, and 20,000 hours on V and VS models.
Motors totally enclosed on H and HS models.
• Motor mounts: rugged, corrosion resistant. All motors or sup-
ports resiliently mounted.
• Fans: aluminum blades; sturdy, balanced, efficient and quiet.
EASY MAINTENANCE
• All parts fully accessible for maintenance, service or replace-
ment.
• Motors readily accessible on model H units, and easily
removable through fan opening on model V units.
