Filtrine Acts to Decrease Global Warming Potential (GWP) of Refrigerants in Its Chillers

Filtrine Eco-friendly Refrigerant Chart

Filtrine has a history of a focus on sustainability. Using eco-friendly refrigerants in its chillers is one area that is highly effective in reducing the impact on the environment.

Beginning in early 2016, Filtrine began to transition towards significantly lower global warming potential (GWP) refrigerants while also increasing energy efficiency of its chillers.  As it did under the Montreal Protocol to protect the earth’s ozone layer, Filtrine is quick to respond to concerns about Climate Change by using the most environment-friendly refrigerants available. 

Many of our chiller models have for years been using hydrofluorocarbons (HFC) refrigerants, R404A or R134a which have zero ozone depletion potential.  However, new refrigerants have recently been developed that have all of the advantages of these refrigerants but much lower GWP. 

Depending on the application, Filtrine chillers that used R404a will now use either R407c (55% lower GWP) or R448a (67% lower GWP).  Chillers that used R134a will now come with R513a which has a 55% lower GWP.  At the same time, there is little or no loss in efficiency.  In some cases, the efficiency improves by as much as 10%.
