Specifications: Made in TaiwanFeatures: Installing a Pre-cooler first compressed air enter there for cool compressed air before it enter the evaporator, (HA Series only has). Non-fouling heat exchanger maintain perfmace heat-exchanger efficiency and low pressure drop fpr the life of the unit; are fully insulated topreserve cooling effectiveness. High quality refrigeration controls produce consistent cooling temperatures over a wide range of flow and operating conditions. eparator maintains high efficency frum no flow to full flow. Durable condensate drain automatically collects and discharges condensate from the system.
