The company states that using a more environmentally-friendly refrigerant, such as R407, could save a lot of money over a chillers' life span. However, AB Systems warns that many engineers overlook this important aspect of a chiller because many arrive from the manufacturer with R410 as the refrigerant.
AB Systems managing director, Jeff Day, stated:
“A 60 kW chiller filled with R410 refrigerant could cost as much as £15,000 a year in running costs, while the same chiller filled with R407 refrigerant would cost significantly less to run, at around £7,000 a year. This is a massive saving – more than 50% - and why AB Systems choose only to specify R407 refrigerant.”
“R410 refrigerant is cheaper than R407, so chillers are often supplied with it – it makes a quote appear more competitive. However, engineers need to be aware that they will be paying a lot more in the long run by using R410, so we’re urging them to pay close attention to any quotes they receive and to look into the cost-saving advantages of R407 refrigerant.”
“It’s easy to overlook the refrigerant used in chillers, but manufacturers can save a significant amount of money every year using a refrigerant with a higher CoP value, such as R407. It’s a small change that will go a long way to driving down the running costs of chillers, as well as contributing to CO2 reduction targets.”
