Full-Size Air-CooledTop-Mounted Air Conditioners (Discontinued)

The Full-Size Air-Cooled Top-Mounted Air Conditioners deliver efficient climate control for electronics enclosures and industrial equipment cabinets. These units feature a built-in condensate evaporator that eliminates the need for manual condensate drainage under normal operating conditions, significantly reducing maintenance requirements. An overflow condensate drain fitting and hose are included for applications in extremely humid environments or those with open or leaky enclosures where additional protection may be necessary.

Each unit incorporates an EMI/RFI suppressor to minimize transient line spikes during compressor cycling, protecting sensitive electronic components from power surges. The multi-layer corrugated aluminum filter with a sturdy one-piece aluminum frame effectively removes contaminants from incoming air, keeping internal components clean and extending equipment lifespan. Replacement filters are readily available through kooltronic.com/spareparts for convenient reordering.

These air conditioners utilize environmentally responsible refrigeration technology. Units with a 4 in the model number designate CFC-free R134a refrigerant where compatible compressors are available, while others employ low Ozone Depleting Potential R22 refrigerant, indicated by a 3 in the model number. An electronic thermostat provides low temperature control that prevents over-cooling while optimizing energy efficiency for cost-effective operation. All Full-Size Top-Mounted models are UL/CUL Recognized, except model KA3C12HTR56, with Listed versions available at additional cost for enhanced compliance documentation.
