The use of heat transfer fluids makes it possible to significantly reduce the refrigerant load (by up to 85% depending on the installation) as well as the risks associated with their use, in particular by confining the primary circuit to an engine room, thereby limiting operating costs and the risk of leaks that could cause potential emissions.
These architectures allow for greater installation flexibility: extensions or modifications are easier to carry out, without major interventions on the main circuit. Maintenance and performance monitoring are simplified because the temperature, pressure and nature of the heat transfer fluid can be adjusted to meet the actual needs of the processes.
Although the use of a heat transfer fluid requires larger equipment and additional energy consumption with a pumping network necessary for the circulation of the heat transfer fluid, there are various solutions available on the market. Selecting a product suited to the technical constraints allows for the optimisation of energy consumption and operating costs.
Among these options, CRANE Temper® offers attractive physical and chemical properties. With its low viscosity and good thermal conductivity, it reduces energy consumption by limiting pressure losses and maximising heat transfer.
CRANE Temper® is a ready-to-use solution formulated with potassium formate and acetate, deionised water and effective corrosion inhibitors.
The advantages of CRANE Temper® :
- Wide temperature range: -60°C to +150°C.
- Low viscosity.
- High thermal conductivity.
- Non-toxic and biodegradable.
- NSF HT1 registered for applications with a risk of accidental food contact.
Focus on its properties:

The low viscosity of CRANE Temper® improves flow and reduces pressure losses in secondary cooling circuits.
Its high thermal conductivity provides more efficient heat exchange, allowing you to work with a higher evaporation temperature setpoint and achieve better compressor efficiency.
