In their joint presentation, Terry Chapp of Danfoss and Jeremy Olberding of Colmac Coil explained the factors behind the resurgence of ammonia DX systems including its low-GWP/ zero ODP, lower power consumption and operating costs. The pair cited a case study at a 403,000 sq ft. (37440 m²) Joliet Cold Storage in Illinois, which has a total refrigeration load of 1007 TR. Advanced DX ammonia systems allow industrial refrigeration systems charges as large as 1,800 TR with a system charge of under 10,000 lbs (4536 kg), offering a value-added alternative to HFC commercial systems.
