Direct Expansion Combined Air Handling Unit

The ZK series direct expansion combined air handling unit is a new generation of DX air conditioning unit with its own cold source to use in the pharmaceutical, chemical and other industrial fields. It transforms the traditional design of chillers plus combined air-conditioning boxes, and changes the original complex dual-water system (chilled water and cooling water system) to an anhydrous system, which simplifies the composition of the system and improves the refrigerant evaporation temperature, reduces installation and operating cost, improves work efficiency and saves energy.
