The ultra-low-charge ammonia units will be installed at Drayton Foods in Fargo, N.D.
Conyers, Ga.-based OEM Hillphoenix has sold its first two NXTCOLD ultra-low-charge packaged ammonia refrigeration units to Drayton Foods to support an expansion at its manufacturing plant in Fargo, N.D.
This represents the first NXTCOLD units designed, manufactured and sold by Hillphoenix since it acquired exclusive licensing rights to the technology in the U.S. last September from Los Angeles-based NXTCOLD, said Tim Henderson, industrial program manager, Hillphoenix, who handled the transaction and discussed it at the IIAR Conference last month.
The Hillphoenix licensing agreement for the NXTCOLD technology extends to Canada, Mexico and Latin America. They will go by the brand, NXTCOLD by Hillphoenix.
Over the past few years, NXTCOLD has installed its units in cold-storage facilities in California, including a KPAC General facility in South Gate; a Lineage Logistics plant in Oxnard; a Baker Cold Storage Facility in Long Beach; a Los Angeles Cold Storage facility, and a Neptune Foods seafood storage warehouse in San Pedro.
“[Drayton Foods] wanted to add a freezer but not go over 10,000 pounds of ammonia.”

The two 60-TR rooftop units will be installed at Drayton Foods – which makes pizza crust, dough balls, bread sticks and dinner rolls – in late May or early June, said Henderson.
NXTCOLD units each contain under 1 lb of ammonia per TR – 6 oz to 8 oz/TR – so the total charge for the two units is less than 60 lbs, he noted.
Drayton Foods, which has an existing ammonia-based spiral freezer and storage area, “wanted to add a freezer but not go over 10,000 pounds of ammonia,” the point at which more restrictive federal safety regulations come into play, said Henderson. The NXTCOLD units keep the charge under that threshold.
Reflecting the cold ambients of North Dakota, the NXTCOLD units are supported by dry fluid coolers that don’t use water, employ a space heater in the units and include additional heating for oil lines, noted Henderson. “We want to show they can work anywhere.”
Hillphoenix also makes transcritical CO2 refrigeration systems for industrial and commercial operators.
