Features and Benefits

Blower Motor: 1/2 to 5 ton

The supply-air (blower) motor is a multi-speed motor with internal ther- mal overload protection. The motor bearings are permanently lubricated and sealed.

All motors are factory wired to the option selected. A high, medium, and low speed tap is provided for field cus- tomization on most voltages. The speed tap modification can be made in the control box of the unit. See Figure 15 for blower motor.

Note: The three-phase designs are pro- vided in a dual or three-speed version only. See fan performance section for factory ratings.

Serviceability to the motor is made through either of the two air-side access doors for the horizontal configu- ration, and through one air-side access door on vertical configuration. The motor and blower wheel are removable by an orifice ring mounted to the fan housing.

Blower Motor: 6 to 20 ton

A belt driven motor selection powers the fan for the 6 through 20 ton dual circuit units. The 6 through 12-1/2 ton units include a single fan assembly. The 15 and 20-ton units include dual fan assemblies. Because the motor sheave and the motor base are adjustable in the field, a greater variation in external static pressures are available.

The large tonnage units are capable of providing 0 ESP to 3.0 ESP allowing a higher static ductwork to be applied on the mechanical system when the appli- cation requires extensive ductwork design. This is a low cost alternative to purchasing, installing, and maintaining multiple smaller tonnage units to meet the required air flow demand for the space.

Access to the 6 through 25 ton units is made through the back of unit by way of two panels, and/or through a side access panel if adjustment to the motor belt or motor base are needed.

Blower Housing

The blower housing is constructed of non-corrosive galvanized steel. A facto- ry-mounted orifice ring is provided for ease of motor serviceability on the 1/2 through 5-ton direct drive units.

All air-side panels are interchangeable with one another for ease of field con- vertibility of the supply-air on the GEH model.

Air-Side Filter

The air-side filter incorporates several- fiberglass options. These filters include an average synthetic dust weight arrestance of approximately 75%. This dust holding capability includes a color- less, odorless adhesive to retain dirt particles within the filter media after fiber contact.

Air-to-Refrigerant Coil

The air-to-refrigerant heat exchanger is constructed of staggered copper tubes with die-formed corrugated lanced alu- minum fins. The fins are then mechani- cally bonded to the tubes through expansion.

The coil is placed internal of the unit design for the GEH model to provides an optional dual filtration application. With dual filtration to the GEH unit, maintenance to the filter is significantly less than with a single filtration system. This design also offers maximum flexi- blity of the supply and return air config- urations.

The maximum working pressure for both the GEH and GEV coils is 450 psig. It is designed for maximum capacity with an additional benefit of physical unit size reduction.
