F-Gas News: Cold storage specialist Dawsongroup signs up to R454A

Specialist specifies Chemours’s Opteon XL40 for its coldroom fleet, following successful installation

Chemours has announced that cold storage specialist Dawsongroup has selected the HFO Opteon XL40 (R-454A) for its fleet, following the successful implementation of XL40 at the Oldham logistics and storage facility.

Since installation in September 2017, the system has been performing reliably and, as a result, Dawsongroup intends to expand the use of XL40 in their fleet.

The Park Cakes installation at the 1,805 cu m low temperature cold store won the partners a Cooling Award for Cold Chain Project of the Year.

Kevin Smith, Technical Manager at Dawsongroup, explained the thinking that led to the specification of R454A: “Selection of the correct refrigerant for the specific application and meeting the needs of the end user was critically important. Alternative refrigerants such as CO2, hydrocarbons or ammonia have proven unsuitable for this project because of equipment unavailability and complexity, high flammability or toxicity risks. This led to the ultimate choice of Opteon XL40 with properties close to that of R404A, allowing the existing equipment design to be used. The mild flammability of this refrigerant can be handled by regular service engineers after simple training, and its very low GWP secures its long-term viability.”

The GWP of Opteon XL40 of 239 is 94 per cent lower than that of R404A (3922), making it a sustainable solution with respect to the F-Gas phasedown, Chemours said. ”It provides an optimal balance of properties and is perfectly suited to positive displacement, direct expansion low- and medium temperature commercial and industrial applications.”
