H10 SeriesAir-Cooled Rack-Mounted Air Conditioners

The H10 Series represents a comprehensive solution for rack-mounted enclosure cooling, combining robust construction with intelligent climate control technology to protect sensitive electronic components in demanding industrial environments. Each unit features a heavy-duty steel shell finished with a baked powder coat in ANSI 61 gray, providing durable corrosion resistance, with custom color options available to match facility aesthetics or organizational standards.

The closed-loop cooling architecture isolates the enclosure interior airflow system from ambient conditions, creating an impermeable barrier that prevents outside air from invading the cool, dehumidified component compartment. This sealed design is complemented by a built-in condensate evaporator that eliminates the need for manual condensate drainage under normal operating conditions, though overflow provisions with drain fitting and hose are included for extremely high humidity applications with open or compromised enclosures. The system utilizes CFC-free R134a refrigerant, meeting environmental standards while delivering reliable heat rejection. An integrated compressor short cycle protector safeguards against frequent restart cycles that can prematurely wear the compressor, automatically preventing operation for several minutes after shutdown or power interruption--particularly valuable in installations subject to solar gain, fluctuating internal loads, or oversized capacity specifications planned for future equipment additions. The multi-layer corrugated aluminum filter design maintains cleanliness of internal components and is easily replaceable through Kooltronic's online spare parts portal.

For facilities operating across varied climates, the optional low ambient kit maintains sufficient operating pressures when temperatures drop below 50 degrees Fahrenheit, with a compressor heater and pressure-modulating condenser blower extending reliable operation to a minimum of 0 degrees Fahrenheit. All H10 Series units feature programmable thermostat and temperature alarm functions, enabling precise temperature control and early alert notifications when intervention becomes necessary. The entire line is UL/CUR Recognized, ensuring compliance with industry safety standards.
