STANDARD FEATURES

208/230/220 & 480 Volt Models
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.
Compressor Short Cycle Protector
- Protects the compressor from possible damage due to harmful short cycling, (frequent starting) where temperature controls enable the compressor to restart frequently or after a power interruption. These conditions could be due to low or fluctuating heat loads within the electrical enclosure or a power failure. The Compressor Short Cycle Protector will prevent the compressor from starting when it has been shut off for less than several minutes or the power was interrupted. By limiting the number of compressor starts per hour, the life of the compressor is prolonged. It is recommended where installations are subject to solar gain and or changes in the enclosure internal load due to the degree of usage of the equipment being cooled. It is also recommended where higher capacity units are specified in anticipation of the future addition of heat producing equipment being added to the enclosure.
Condenser Blower Controller
Epoxy-Coated Condenser and Evaporator Coils
- Condenser and Evaporator 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.
External junction box for permanent wiring connections
- For 480 Volt models
Filters
- All KOOLTRONIC filters consist of a multi-layer grid of sturdy corrugated aluminum, securely held in a one-piece aluminum frame. Filters are required wherever air is drawn into an electronics enclosure or related cooling equipment to keep internal parts as clean as possible. A non-drying adhesive coating traps a high percentage of particulate matter. These filters are reuseable, they may be washed and recoated with the appropriate filter recoating adhesive. Replacements are available for those which become damaged or otherwise non-serviceable.
Heavy-Duty Steel Shell
NEMA 12, 3R & 4 Ratings Maintained (UL50)
- All units Maintain NEMA 12 & 3R Ratings. All units are fully gasketed for tight, leakproof installation, in compliance with the NEMA Type 4 Enclosure Ratings.
Programmable Temperature Alarm
- All models feature a programmable temperature alarm to alert if early action is required.
Programmable Thermostat
- All models feature a programmable thermostat, allowing more accurate and versatile performance features.
Six-Foot [1.8m] (minimum) 3-Wire Power Cord
UL/CUL Listed
Zero ODP Refrigerant
- R410a, an HFC having zero ozone depleting potential.
