The K9 Recirculating Chiller is now classified as Non-Standard and is no longer included within our standard product offering.

The K9 was developed for higher-capacity industrial and OEM applications requiring reliable process cooling and precise temperature control. Its robust design made it suitable for demanding applications where consistent cooling performance is essential.

For new applications, we recommend the H12 Recirculating Chiller, ATC’s current low-GWP alternative. The H12 uses R454C refrigerant, offering a more environmentally responsible cooling solution in line with evolving F-Gas legislation.

The K9 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 K9 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 K9 or require a suitable replacement, please contact our team to discuss your requirements.
