Specifications

General Contractor shall furnish and install steam/hot water unit heater(s). Performance shall be as indicated on the equipment schedule in the plans. Unit heater(s) shall listed by ETL as certified.

Units Self-contained, factory assembled, pre-wired unit consisting of cabinet with supply fan, motor, and condenser.

Casing

Two circular steel covers of not less than 18 gage cold rolled die-formed steel covers. With the coil in between, the covers are securely bolted together to form a single unit. The bottom cover shall have a die-formed fan venturi and safety fan guard and the top cover shall include an inner cone for motor mounting to provide a heat shield from radiant and convected air from the heating elements. Every casing part will have a phosphate covering applied after cleaning and then be coated.

Coating Electrostatically applied baked on grey-green corrosion resistant, polyester powder coat paint that meets the following tests:

1. 500 hours of salt spray as defined in ASTM B117.

2. Adhesion/crosshatch tape tests as defined in ASTM D3359, Method B, Rating 5B.

3. Will not crack or peel when test panel is bent around a 1/8 inch arbor.

Condenser Condenser coils are of the extended surface type, utilizing aluminum fins and continuous DLP-type copper tubes with Schedule 40 steel pipe supply and return headers. Tubes are mechanically bonded to the collars of the fins. All tube joints are silver brazed. The condensers are warranted for operation at steam or hot water pressures up to 150 pounds per square inch gauge and/or temperatures up to 375°F. All coils are leak tested at 165 to 200 psig, air under water. Fins are continuous across the width and depth of the condenser and are vertically oriented to minimize the collection of dirt and dust.

Coils are circular, providing for natural expansion. Each tube is continuous between supply and return header. All tube joints are silver soldered. Copper tubes are 5/8" O.D. with 0.028" wall thickness.

Explosion Proof Unit Fluid Temperatures Fluid temperatures may not exceed 329°F and pressures in excess of 87 psig in hazardous duty applications.

Explosion Proof Motor Single motor with a supply voltage of 115/60/1 and horsepower of 1/2 as indicated on the equipment schedule and manufactured in accordance with NEMA standards for continuous fan duty type applications. Must be enclosed air over and have built in thermal overload protection.

Suitable for Class I, Group D; Class II and III, Group F and G atmospheres. Will be mounted to the unit with rubber vibration absorbing material. All wiring will terminate in an explosion-proof junction box integral to the motor.

Fan/Fan Guards Fans AMCA rated direct drive, aluminum blade, steel hub propeller will be statically and dynamically balanced. Unit shall be equipped with a safety fan guard.

Accessories The following items are to be field installed in accordance with the manufacturer's instructions:

For three phase supply voltages, all motor starters (115V Coil) are Supplied By Others and field installed.
