Why desires for a food grade safe fluid drive a brewery to select Kilfrost.
A large-scale brewery in Saint Lucia, which recently celebrated a 50-year milestone, adopted Kilfrost ALV Plus for its cooling system as it supports its ongoing commitment to continuous innovation and sustainability.
Kilfrost ALV Plus was positioned to Tino Sperling, the then project manager at the site, ahead of a brewery upgrade. What attracted the project manager to the product was its food contact safe certification, as previously the site used a glycol-based fluid, which can have contamination risks and be harmful to health if not handled correctly.
A further attractive benefit was the consistent low viscosity Kilfrost ALV Plus, even in cold temperatures, which results in the reduction of operating costs and CO2, when compared to MPG.
The large-scale brewery required more than 10,000litres of Kilfrost fluid to replace the glycol fluid that had been drained and flushed from the system. The change out took place during a planned upgrade of the site which also included installation of a new pump system, sensors and controls.
Kilfrost supplied the fluid to site and worked with the project manager to provide the correct water ratios for mixing the fluid.
The high performance of ALV Plus ensures that if a drop in temperature occurs, the pump rate can remain consistent, which means that the system can last longer from not being overworked. Also, energy costs don’t then need to fluctuate during temperature changes.
Operationally, risks to health are reduced as it is certified to the US NSF standard as safe for incidental food and beverage contact. It also has non-corrosive properties and it has been tested to and exceeds ASTM D1384-05 corrosion test standard at 88°C, again this can extend the lifespan of the system.
Tino Sperling, project manager at the Saint Lucia brewery, commented: “I was really intrigued by the fluid when a colleague brought it to my attention. ALV Plus is a fantastic alternative to the concerns I had in using MEG, which can be toxic. And it has enabled electricity usage for powering the system to stay the same throughout the year.”
Kilfrost can work directly with breweries and system installers to supply its heat transfer fluids that consistently outperform glycol-based fluids such as MEG.
