STANDARD FEATURES
Below-Ambient Cooling Capability
Closed-Loop Cooling
The enclosure interior airflow system is isolated from the ambient airflow or waterflow system. No ambient air can invade the cool, dehumidified sensitive component compartment.
Epoxy-Coated Heat Exchanger Coils
Heat Exchanger Coils are epoxy-coated. This coating will withstand 1000 hours of salt spray per the ASTM B 117 test method. Also see Stainless Steel Cabinet or Integrity NEMA 4/4X Air Conditioners. NOTE: Severe operational environments such as waste water treatment and salt spray are likely to cause corrosion failure over a period of time regardless of coating. Warranty: Corrosive conditions may affect the warranty coverage. Consult factory for warranty limitations in corrosive environments. NOTE: For additional corrosion protection options, contact factory.
Heavy-Duty Steel Shell with Baked Powder Finish
NEMA 12 & 3R Ratings Maintained (UL50)
All units are fully gasketed for tight, leakproof installation, in compliance with the NEMA 12 and 3R Enclosure Ratings.
UL/CSA Ball-Bearing Motors
All motors, whether permanent split capacitor or shaded pole, are UL/CSA Recognized and include automatic-reset thermal overload protection. Designed for low temperature rise, Kooltronic motors are also cooled by the blowers' intake air, for maximum motor life. All motors are UL Recognized and carry a Declaration of Conformity to applicable CE Standards. Special permanent lubricants perform over a broad temperature range: -20°F (-29°C) to 250°F (121°C).
UL/CUL Listed
ACCESSORIES AND OPTIONS
Automatic Water Flow Control
This control consists of a temperature control thermostat and a solenoid valve. When the temperature within the enclosure drops below the thermostat set point due to decreased load or decreasing water temperature, the thermostat closes the solenoid valve. When the temperature increases to the set point (plus a differential) the thermostat opens the solenoid valve and the supply water cools the enclosure. In most models the Automatic Water Flow Control also includes a bypass flow meter which allows a small amount of water (0.25 gpm) to pass through the heat exchanger at all times.
High Water Level Detector
Closes water-supply valve to prevent flooding if excess water accumulates in the drain pan. Signal circuit activates a user-supplied warning device. The low voltage power for the signal circuit is supplied by the user.
Internal Corrosion Protection
This protection increases reliability in hostile environments. This protection for the refrigeration system consists of an air cured coating applied to the brazed joints on the condenser side, providing a degree of protection from corrosive environments. This coating will withstand 1000 hours of salt spray per the ASTM B 117 test method. Also see Stainless Steel Cabinet or GuardianX Air Conditioners. NOTE: Severe operational environments such as waste water treatment and salt spray are likely to cause corrosion failure over a period of time regardless of coating. Warranty: Corrosive conditions may affect the warranty coverage. Consult factory for warranty limitations in corrosive environments. NOTE: For additional corrosion protection options, contact factory.
Low Airflow Detector
Similar to the Airflow Switch shown in the Blower Accessories Section, the switch is installed in a suitable location in the air conditioner to detect loss of airflow, and sends a signal to a terminal block, through which user-installed wiring and warning devices are activated.
Other voltages and frequencies
Special materials or finishes
Special motors, line cords or connectors
Temperature Alarm
A thermostat is mounted inside the cabinet and attached to a sensor in the warm air return. When the air temperature increases to the set point, a signal is sent to a terminal block. User-installed wiring from the terminal block to local and/or remote warning devices (light, bell, siren, etc.) can be for normally open or closed operation.
