STANDARD FEATURES

  • 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.
  • NEMA 4/4X Rating Maintained (UL50)
    • All units are fully gasketed for tight, leakproof installation, in compliance with the NEMA 4 and 4X Enclosure Ratings.
  • Stainless Steel Shell
    • For applications in corrosive or other hostile environments such as those requiring Internal Corrosion Resistant Coatings, especially where chemical/moisture combinations are present.
  • 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.
