Decide n Pay, which at the moment has 22 transcritical CO2 shops, can be working to get its franchisees to undertake pure refrigerants.
South African retailer Decide n Pay has determined to make use of solely pure refrigerant refrigeration in its company shops, whereas attempting to persuade its franchisees to check the know-how, mentioned Richard Taylor, basic supervisor of design and growth. implementation of shops at Decide n Pay.
Taylor shared the chain’s refrigeration technique throughout a web-based end-user panel dialogue on the ATMO Digital Present (VTS) on Pure Refrigerant Applied sciences on March 30.
Decide n Pay operates 1,498 shops in whole, together with clothes and liquor shops. The retail meals shops are divided between 308 company shops and 471 shops managed by franchisees. The corporate operates primarily in South Africa, but in addition in Namibia, Botswana, Zimbabwe and Zambia. The chain has just lately began to increase additional north into Africa, Nigeria.
By the top of 2020, Decide n Pay had put in 22 company shops with transcritical CO2 refrigeration methods, with seven extra deliberate by mid-2021. 5 of the upcoming shops can have new methods and two can have renovations on present subcritical CO2 shops.
In reviewing the corporate’s future plans, Taylor mentioned that “our firm’s mandate going ahead is to make use of pure refrigerants.” For brand spanking new shops and renovations, CO2 would be the first selection, however for smaller shops, Decide n Pay can be searching for a brand new propane (R290) water loop system from Carel.
For a brand new massive distribution heart, which requires a refrigeration system with a capability of round 7 MW (1,990 TR), Decide n Pay has opted for ammonia. “We severely thought-about CO2 as an choice there, however felt that ammonia was going to be the extra conservative route, ”Taylor defined.
In company shops, Decide n Pay began adopting pure refrigerants in 2008. The primary conversions had been two supermarkets in Cape City and Johannesburg, each outfitted with ammonia / CO2 refrigeration methods. Within the third retailer, Decide n Pay put in an ammonia glycol system, with an built-in air-con system.
In 2009 the corporate additionally began utilizing R134 / CO2 cascade methods. Taylor described these methods as “dependable, environment friendly and value efficient to take care of.”

Make the leap
Though the premium on pure refrigeration methods has dropped significantly lately, it stays 10-15% dearer, making it tough to attempt to persuade Decide n Pay franchisees to take a position on this premium, Taylor mentioned. . One franchisee took the plunge, nonetheless, and was “very pleasantly stunned,” Taylor mentioned. We hope this constructive expertise will lead extra franchisees to observe go well with, he famous.
One other problem with franchisees is their notion that CO transcribes2 won’t be as vitality environment friendly at excessive ambient temperatures. This, nonetheless, is “a fantasy” that has now been “shattered,” Taylor mentioned.
The experience of native technicians, particularly in additional distant areas, was additionally a priority, as had been the lengthy lead occasions for supply of methods from Europe. However these two considerations are diminishing, Taylor mentioned. The lengthy lead occasions are primarily as a consequence of COVID-19 restrictions, and native contractors have perfected themselves to work with pure refrigerants.
Decide n Pay can be serving to franchisees scale back the refrigeration footprint of their shops, with narrower checkouts, doorways and lids on all checkouts, and switching to extra vitality environment friendly checkouts. The R290 water loop methods will even current an excellent choice for franchise takers, Taylor mentioned.
In a brief time period from 2016 to 2018, we noticed this bounty [on CO2 equipment] go from 40% to a ten% premium, “- Richard Taylor
