K4 4.5kW Recirculating Chiller

The K4 Recirculating Chiller is now classified as a Non-Standard Unit and is no longer included within our standard product offering.

The K4 was developed to provide reliable temperature control for laboratory, industrial, and OEM applications requiring consistent process cooling. Its robust design made it suitable for a variety of applications where dependable cooling performance and precise temperature regulation are essential.

For new applications, we recommend exploring the H-Series, ATC’s current generation of low-GWP recirculating chillers, offering modern refrigerant technology and long-term support.

The K4 may still be available for existing installations, replacement projects, or specialist applications where this configuration is required. Our Sales and Engineering teams can review your requirements and assess whether a K4 can continue to be supplied.

All Non-Standard Units are subject to technical review, component availability, and current regulatory requirements, with specifications, pricing, and lead times confirmed individually.

If you have an existing K4 or require a suitable replacement, please contact our team to discuss your requirements.
