The Koolance VLX-450 Chiller subassembly is now available for order. The VLX-450 is a ready-to-integrate, inline, open frame chiller rated at 450W of cooling with a 0°C liquid-ambient delta. The VLX-450 uses standard G 1/4 fittings so the chiller can be easily added into any existing standard cooling loop.

The VLX-450 chiller moves coolant through its stainless steel plate heat exchanger. The VLX-450 features a mounted control knob that allows the user to adjust the compressor’s cooling performance. Also, the wire terminals of the chiller are placed in a readily-accessible location if ever an alternative control scheme is desired by the user. Note that fittings and coolant pump are not included with the chiller sub-assembly.

For first use after installation, ensure the chiller is upright for at least 24 hours before applying power to ensure sufficient oil reaches the compressor.
