CAPACITY CONTROLS

Dual Fan Motors—The dual fan motor package is available as a proven energy saving capacity control option. It consists of furnishing a high efficiency motor, a 1200 RPM, low speed motor, two sets of drives and belts, extended fan shaft and motor bases on opposite sides of the blower. A UL control-starter panel is available as a completely wired package for one point connection.

Variable Speed Drive—A Variable Speed Drive automatically minimize the tower’s noise level during periods of reduced load and/or reduced ambient temperature without sacrificing the system’s ability to maintain a constant cold water temperature. This is a relatively inexpensive solution, and can pay for itself quickly in reduced energy costs.

Electric Damper Controls—An electric damper control package is available as an accessory for modulating the internal damper system. A proportional solid state actuator is factory mounted below the fan scroll and attached to the damper shaft by connecting linkage. A sensing bulb connected to the actuator by a capillary tube is normally mounted in the unit pan water basin for monitoring the system. However, when specified, a pressure control may be supplied for field mounting to allow direct head pressure control. An end switch located inside the motor actuator may be adjusted to cycle the fan motor on for pressure rise and off when dampers close.

CASING INSULATION

In order to further reduce the heat loss from the unit coil, factory installed insulation on exterior coil panels is available. A protective coat of paint is applied to the insulation for protection from the weather elements.

CONTROL – STARTER PANEL

Contains the fan motor starter, disconnect switch, thermostat sensing the cold water temperature to control the fan motor and control transformer when required by the supply power characteristics. All components are contained in a NEMA 12 enclosure with UL label and mounted on the unit. Fan motor and controls are factory wired to the panel to provide single point connection for users power supply.

Panels for dual fan-motor arrangement include elapsed time meters for both motors to aid in determining energy savings. NEMA 3R and 4 enclosures are also available.

VIBRATION ISOLATORS

Spring type vibration isolator rails may be supplied for field installation—some units will require base frame structural support.

ELECTRONIC WATER LEVEL CONTROL

The electronic water level control package provides a constant and accurate means of monitoring water level in the unit. For this reason, it is often recommended for those installations which require year round operation in low ambient conditions.

The complete package includes an electric float switch with stilling chamber which is factory installed in the pan section of the unit. An electric solenoid valve for water make-up

is shipped loose for remote installation. All wiring must be provided in the field by others.

PAN HEATER

The use of a remote sump tank located indoors is a common form of pan water freeze protection for evaporative cooling equipment. However, for those installations which will not allow this type of system, freeze protection may be provided by electric immersion heaters or steam or hot water coils installed in the pan.

The electric heater package consists of immersion heaters installed in the pan to provide efficient even heat distribution. Standard heaters are selected to provide approximately 40°F pan water at -10°F ambient temperature. A low water cutout switch is supplied to prevent heater operation when the elements are not completely submerged. The heaters are monitored by a sump thermostat with remote sensing bulb located in the pan water. All heaters and controls are factory installed for field wiring by others.

NOTE: Pan heater packages are designed to prevent pan water freezing during unit shutdown with fans and pump idle.

STAINLESS STEEL CONSTRUCTION

In addition to the standard stainless steel basin, fill supports and access doors, 300 stainless steel construction is offered as an option for upper casing panels.
