Legacy H9 SeriesAir-Cooled Rack-Mounted Air Conditioners

The Legacy H9 Series comprises air-cooled rack-mounted air conditioners designed to maintain precise temperature control in enclosed electronics environments while prioritizing environmental responsibility and operational efficiency. All units utilize either CFC-free R134a refrigerant or low-ODP R22 refrigerant, depending on compressor compatibility, with the model number designation clearly indicating which refrigerant is employed (a "4" between the A and C signifies R134a, while a "3" denotes R22).

Each unit is equipped with an EMI/RFI suppressor that minimizes transient line spikes during on/off cycling, protecting sensitive electronic equipment from potential power-related disturbances. The integrated electronic thermostatic low temperature control prevents over-cooling while optimizing energy consumption, reducing operational costs without compromising temperature stability. All Legacy H9 models incorporate Kooltronic's proven multi-layer corrugated aluminum filter design, securely mounted in a one-piece aluminum frame to prevent dust and contaminants from entering the enclosure and degrading component performance.

The Legacy H9 Series is fully UL/CUL Listed across all models, meeting rigorous safety and performance standards for industrial and commercial applications. Replacement filters are readily available for convenient maintenance and can be ordered online through kooltronic.com/spareparts. For specific refrigerant status and model availability, consult Kooltronic at the time of requirement to ensure your system meets current regulatory compliance.
