Horizontal Super-Mini SeriesAir-Cooled Top-Mounted Air Conditioners

The Horizontal Super-Mini Series Air-Cooled Top-Mounted Air Conditioners deliver efficient, closed-loop cooling specifically engineered for protecting sensitive electronics in compact enclosures where space and environmental control are critical concerns. These units maintain a completely isolated interior airflow system that prevents ambient air from contaminating the cool, dehumidified component compartment, ensuring optimal operating conditions for temperature-sensitive equipment regardless of external conditions.

The cabinet features a heavy-duty steel shell with baked powder finish in ANSI 61 gray, with custom color options available to match facility standards. The epoxy-coated condenser and evaporator coils provide robust corrosion resistance, withstanding 1000 hours of salt spray testing per ASTM B 117, making them suitable for moderately demanding industrial environments. A built-in condensate evaporator system eliminates the need for manual drain management under normal operating conditions, though extremely high humidity situations with open or leaky enclosures will require the included overflow condensate drain fitting and hose. The multi-layer corrugated aluminum filter keeps internal components clean and is easily replaceable through Kooltronic's online parts catalog.

Advanced controls and protective systems maximize equipment reliability and operational flexibility. A compressor short cycle protector prevents damage from frequent starts caused by fluctuating heat loads or power interruptions, significantly extending compressor life in installations subject to solar gain or variable equipment usage. A programmable thermostat delivers precise temperature control with enhanced versatility, while a programmable temperature alarm provides early notification of thermal deviations. For facilities operating in cold climates, an optional low ambient kit maintains sufficient operating pressures down to 0F by incorporating a compressor heater and pressure-sensing condenser blower modulation. All units utilize CFC-free R134a refrigerant and maintain NEMA 12 rating compliance with fully gasketed construction for leak-proof installation. The series is UL/CUR Recognized.
