Secondary Refrigerant Systems
Secondary Refrigerant Systems for cold rooms or cold stores, feature an outdoor glycol chiller interconnected to the indoor blast coolers with mild or stainless steel pipework through which low temperature food safe glycol is circulated.
Secondary Refrigerant systems have many benefits over a traditional Direct Expansion system:
- A simple and easy to install pipework system with no expensive refrigeration skills required
- A significant reduction in system refrigerant volumes
- No leaking of refrigerants into the cold space
- Easier conformance with F Gas Regulations
- Lower life time service and maintenance costs
- A system which can easily be extended

Packaged low temperature glycol chillers
Low temperature glycol chillers can be applied for process cooling or as part of a secondary refrigerant system for chilled and cold storage applications. Packaged chillers can be supplied in a range of capacities with the capability to provide glycol at temperatures from +5°C to as low as -40°C.
These chillers are designed and manufactured specifically for low temperature applications in contrast to a medium temperature chiller modified to operate at some lower temperature.

Features include:
- Scroll or screw compressors.
- Plate or shell and tube type evaporators.
- Air or water cooled condensers.
- Intuitive multi functional micro processor controller
- Integral glycol circulating pumps
The result is a highly reliable perfectly balanced chiller which will perform precisely to its specification.
