Hitachi Industrial Equipment Systems Refrigerated Air Dryer HDR Series
Hitachi Industrial Equipment Systems
Low-pressure loss stainless steel heat exchanger and refrigerated air dryer with various protective functions.
Features - Adoption of low-pressure loss all-stainless steel plate heat exchangers (HDR-7.5AX2, 15/22/37AG1, 55~100AX) Pressure loss has been reduced to less than 1/3 compared to conventional models, improving energy efficiency and corrosion resistance. - Standard remote operation and fault indication functions Equipped with remote operation capabilities. Switching between on-site and remote operation can be freely selected from the instrument panel, and it also supports interlocking operation with air compressors. Additionally, the fault indication function alerts you with a fault lamp in the event of any trouble. - Instantaneous power interruption restart circuit included (HDR-7.5AX2, 15/22/37AG1, 55~100AX) Standard feature includes an automatic restart function for power outages of up to 5 seconds. - LED bar display for refrigerant high-pressure side pressure (HDR-7.5AX2, 15/22/37AG1, 55~100AX) The high-pressure side pressure of the refrigerant is displayed on an LED bar.
