System Requirements:

  • An external pump is required with Delta Star chillers to move water thru the heat exchanger. Pump not included.
  • Observe min/max flow rates critical to chiller operation in ‘Specifications’ table
  • Chiller must not be placed in a confined space, as restricted air flow will limit the efficiency and lifespan of the chiller unit. Do not restrict airflow by placing unit in a cabinet or closet.
  • A Cold Water Cap Tube (CWCT) is required for desired water temps between 50-65F on available models. Standard units operate in the range of 65-85 F.  Call to order.
  • A Thermal Expansion Valve (TXV) is required for lower desired water temps between 40-80F on available models. Standard units operate in the range of 65-85 F. Call to order.
