This model includes louver diffuser. Also available without.
Construction:
Contractor shall supply and install heavy duty ceiling mounted forced air
electric heater(s) of the wattage, voltage and phase as indicated on the plans.
The heater shall so be designed to provide an even distribution of heated air
to the space to be heated by drawing return air in the periphery of the heater,
across and through the element and be discharged from the center section of
the heater by mean of an electric motor and axial flow fan blade.
Motor:
Motor shall be permanently lubricated, unit bearing, totally
enclosed shaded pole type with impedance protection. Motors shall operate
at no more than 1300 RPM and shall be same voltage as the heater
Performance:
Heaters shall have a rating of 600 CFM at 1,000 F.P.M.
with a maximum temperature rise of 44°F and 63.9 DB RE 1012 Watt
Element:
Element assemblies shall consist of two or three corrosion
resistant steel sheathed type elements mechanically bonded to common
corrosion resistant steel fins. Each sheathed element shall consist of helically
coiled Nickel Chromium alloy resistant wire completely embedded in and
surrounded by Magnesium Oxide, enclosed and wedged into corrosion
resistant steel sheaths. Elements shall have 2″ cold conductor pins extending
into sheath and shall have a density of no more than 60 watts per inch.
Thermal Overload:
Heaters shall be equipped with a “manual
reset” thermal overload which disconnects elements and motor in the event
normal operating temperatures are exceeded. For safety, if opened due to
abnormal temperature, thermal overload shall remain open until manually
reset. Automatic reset thermal overloads which allow the element to continue
to cycle under abnormal conditions will not be accepted.
Commercial and Institutional Applications:
Use in –
vestibules, entrance ways, lobbies, rest rooms and small office and guard
building applications.
