VLX-450 is a ready-to-integrate, compact, open frame chiller. Cooling performance is 450W, or 1535 BTU/hr @25°C liquid & ambient (0°C delta-T). External liquid coolant must be pumped through the VLX-450's copper-brazed stainless steel plate heat exchanger via two G 1/4 BSPP fittings. Fittings and coolant pump are not included.

A mounted control knob adjusts the compressor's performance. Wire terminals are readily accessed if an alternative control scheme is desired.

  • Cooling capacity: 450W (1535BTU/hr) @ 25°C liquid/ambient
  • Refrigerant: R-134a
  • Power input: 24VDC, 250W
  • Designed for an operational temperature range of 0-40°C (ambient and liquid)
  • G 1/4 BSPP threads on plate heat exchanger for inlet/outlet fittings

NOTE: Requires 24VDC input power. Koolance offers a separate power supply for AC wall outlet sources. Keep unit upright at all times, and for at least 24 hours before applying power to ensure sufficient oil reaches the compressor.

Liquid Coolants

Koolance's product warranty does not cover the use of 3rd-party coolants, coolant additives, or corrosion. Koolance LIQ-702 or LIQ-705 coolants are strongly recommended to help avoid issues with mixed metals or biological growth. Additionally, do not use aluminum with bare (unplated) copper or bare (unplated) brass in the same system. Do not use silver with nickel in the same system.
