• Available in either top or bottom evaporator air discharge model
• Baked Powder Finish
• 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.
• Condenser Blower Speed Controller
A speed control sensing bulb located in the condenser air outlet area switches the condenser blower between minimum and maximum speed based on the ambient temperature. This reduces noise levels, fan cycling, compressor cycling and prevents the unit from freezing.
• Crankcase Compressor Heater
120V or 240V heater attached to the compressor crankcase to maintain appropriate temperatures during cold operating conditions.
• Heavy-Duty Steel Shell
• Low Temperature Control Thermostat
Electronic Thermostatic Low Temperature Control prevents over-cooling and provides energy-efficient operation.
• NEMA 12, 3R & 1 Ratings Maintained (UL50)
Fully gasketed for tight, leakproof installation, in compliance with the NEMA 12, 3R & 1 Enclosure Ratings.
• Six-Foot [1.8m] (minimum) 3-Wire Power Cord
• Tamper-resistant hardware
• UL/CUL Recognized
• Zero ODP Refrigerant
R410a, an HFC having zero ozone depleting potential.

• Enclosure Heater
Eliminates damaging condensation, increasing reliability of electrical enclosure components.
• 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.
• Remote Thermostat Relay
Used only with a user-installed remote thermostat or the Kooltronic KLLC100 Lead Lag Controller, this 24VAC relay can be used for the sequential operation of two units or with a single unit. An external terminal strip is provided for field interconnection. NOTE: User-installed thermostat must have a set point of 75°F with a differential of 11°F. NOTE: A factory installed thermostat is not provided with this option.
• Special paint finishes
• 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.
