CAPACITY CONTROLS  
VIBRATION ISOLATORS  
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.  
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.  
Variable Speed Drive—A Variable Speed Drive  
automatically minimize the towers noise level during  
periods of reduced load and/or reduced ambient  
temperature without sacrificing the systems ability to  
maintain a constant cold water temperature. This is a  
relatively inexpensive solution, and can pay for itself quickly  
in reduced energy costs.  
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.  
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.  
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.  
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  
NOTE: Pan heater packages are designed to prevent  
pan water freezing during unit shutdown with fans and  
pump idle.  
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.  
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.  
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.
