• 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 Controller
• EMI/RFI Suppressor
EMI/RFI Suppressor minimizes transient line spikes during on/off cycling.
• Epoxy-Coated Condenser Coil
This coating will withstand 1000 hours of salt spray per the ASTM B 117 test method. Also see Stainless Steel Shell 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.
• Filter
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 reusable, they may be washed and recoated with the appropriate filter recoating adhesive. Replacement filters are available and can be ordered online at kooltronic.com/spareparts.
• Heavy-Duty Steel Shell
• Low-ODP Refrigerant
CFC-free R134a Refrigerant is used in all air conditioners for which compatible compressors are available. All others contain low Ozone Depleting Potential (ODP) R22 Refrigerant. The model number reflects the refrigerant. A 4 between the A and C signifies R134a; a 3 signifies R22. Consult KOOLTRONIC for status at time of requirement.
• Low Temperature Control Thermostat
Electronic Thermostatic Low Temperature Control prevents over-cooling and provides energy-efficient operation.
• Mounts Externally
• 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.
• Textured Baked Powder Finish
"BAKED POWDER FINISH: Durable, baked-on beige powder finish is standard. Other finishes are available.*

* See Profile Indoor/Outdoor, Integrity NEMA 4/4X and Intrepid Series for different specifications applicable."

• UL/CUL Listed

• Enclosure Heater
Eliminates damaging condensation, increasing reliability of electrical enclosure components.
• Filter Recoating Adhesive
This compound is a superior product for recoating filters after washing. The adhesives penetrate dirt layers to keep the filter surface tacky for longer effective performance between washings.
• 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.
• Other voltages and frequencies
• 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.
• Replacement 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.
• Special paint finishes
• Stainless Steel Shell
• 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.
