Kilfrost has launched a heat transfer fluid formulated with sustainable GRAS heat transfer fluid bases and a low circulating viscosity to improve system efficiency.
The company claims that installers of chillers, secondary refrigeration units and process cooling equipment no longer have to compromise between efficiency and toxicity.
In a statement it said: “Optimum efficiency in relevant application areas would be achieved by the use of monoethylene glycol (MEG) based fluids. However, the toxic nature of MEG-based products limits their use in the market.
The currently used lower toxicity alternatives have been based on mono propylene glycol (MPG), a chemical that is generally recognised as safe (GRAS). Such low toxicity alternatives are far less efficient in their heat transfer properties due to a higher viscosity than MEG based fluids.
The viscosity of Kilfrost ALV is significantly lower than MPG-based products, showing up to a 60 per cent reduction at sub-zero circulation temperatures, which leads to lower pumping costs and greater overall system efficiency.
This makes it a cost-effective investment when looking for a heat transfer fluid to use within systems. In addition, when considered during the design stage, Kilfrost ALV offers an opportunity to reduce costs on pipe and pump sizing.
Problems caused by corrosion can have a considerable impact on the life span and reliability of a system, with a poor quality heat transfer fluid quickly becoming the most expensive part of a cooling system despite the low initial cost.
The new product exceeds the ASTM D 1384-05 corrosion test standard and provides high levels of corrosion protection with an assured longevity of system operation.
Gary Lydiate, chief executive at Kilfrost commented: “Kilfrost ALV has been designed to provide greater peace of mind with its safety credentials, whilst improving system efficiency. The new product has been in development for a number of years and is going to be a real game changer in the industry. ”
Kilfrost continues to invest in the development of the next generation of heat transfer fluids, with improvements in performance and efficiency.
