Boosting environmental credentials
Published: 20 May, 2021
HI-LINE INDUSTRIES, an established UK manufacturer of high-quality compressed air purification equipment, has released the 2021 version of its energy-efficient Tundra refrigeration dryers. Most notable among the enhancements is a switch of refrigerant to R513a in models up to and including Tundra 115 (115 cfm, 195 m3/hr capacity). A HFC/HFO blend, R513a refrigerant has no ODP (Ozone Depletion Potential) and a much reduced CO2 impact in comparison with the previous R134a refrigerant. As a result, the company says customers can rest assured that Hi-line is continuing its commitment to sustainability in manufacturing by minimising its carbon footprint.
The F-Gas regulation means that refrigerants with a GWP (Global Warming Potential) of more than 2500 are now subject to a ban. However, while R134a is below this limit and remains legal, it is sufficiently high for the regulation to stipulate an incremental phasing-down of production quotas to help reduce environmental impact. R513A is widely viewed as the optimum replacement.
Importantly, R513a is an A1 safety group refrigerant and is neither toxic nor combustible. Unlike flammable refrigerants, R513a is subject to less stringent regulations in handling, maintenance intervals and compulsory leak tests, thus saving time and money.
Hi-line says switching to R513a builds on the sustainable credentials of the Tundra range, which is already renowned for its optimised energy efficiency via capabilities such as minimal pressure drop and lower absorbed power. Reduced energy consumption is vital in today’s ultra-competitive marketplace, which is why Hi-line says it has worked hard to offer customers a dryer solution that drives down energy costs.
