H9 Series SwitchableAir-Cooled Rack-Mounted Air Conditioners

The H9 Series SwitchableAir-Cooled Rack-Mounted Air Conditioners deliver efficient thermal management for electronics enclosures with environmentally responsible refrigerant technology and intelligent climate control. These units feature a built-in condensate evaporator that eliminates the need for manual condensate drainage under normal operating conditions, significantly reducing maintenance overhead and installation complexity. An overflow condensate drain fitting and hose are included as a safeguard for extreme humidity scenarios or compromised enclosures where additional moisture management may be required.

Environmental compliance is built into every unit through CFC-free or low-ODP refrigerant selection. Most models operate with CFC-free R134a refrigerant where compatible compressors are available, while others utilize low Ozone Depleting Potential R22 refrigerant. The model number designation clarifies the refrigerant type--a "4" between the A and C indicates R134a, while a "3" signifies R22. Consult Kooltronic for current refrigerant availability at the time of your requirement.

The H9 Series incorporates an EMI/RFI suppressor to minimize transient line spikes during on/off cycling, protecting sensitive electronics from power disturbances. A robust multi-layer corrugated aluminum filter with one-piece aluminum frame keeps internal components clean and extends equipment life; replacement filters are readily available for order online at kooltronic.com/spareparts. An electronic thermostatic low temperature control prevents over-cooling and optimizes energy efficiency by maintaining precise temperature setpoints. This series carries UL/CUL Recognized certification, meeting rigorous safety and performance standards for industrial and commercial applications.
