AIREDALE EasiCool 6-64kW Precision Air Conditioner Technical Manual

  • Hello! I'm your chat assistant, and I've reviewed the Airedale Technical Manual for EZRE Downflow and Upflow Precision Air Conditioning units. This technical manual details the specifications, features, and operation of these direct expansion units which come in both air-cooled and water-cooled configurations. These units are designed for environments requiring precise air control like data centers and labs. I'm ready to answer any questions you may have about the content of the manual.
  • What type of refrigerant does the Airedale Easicool unit use?
    What is the recommended copper tube size for connecting the discharge stub to the condensate pump?
    What is the maximum water temperature flowing through the chiller?
