Use of Eco-friendly Low GWP Refrigerants in Chillers Helps with Sustainability

Filtrine Eco-friendly Chiller HFO Refrigerants

Chilling a process whether medical or industrial usually requires the use of refrigerants.  A refrigeration system is a closed loop circuit in which the refrigerant absorbs heat where cooling is desired (in the evaporator) and then moves the heat to some other point (the condenser) where the heat can be rejected.  The refrigerant itself is recirculated over and over again.

Starting with the Montreal Protocol in 1987, there is has been a push to make sure refrigerants do not harm the environment if they should leak out. The industry successfully switched to new refrigerants to stop the depletion of the earth’s ozone layer. More recently, the world is focusing on reducing the potential for adding greenhouse gases to the atmosphere.  Filtrine has a history of sustainability. Using eco-friendly refrigerants in Filtrine 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 Filtrine 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%.
