The next logical step in natural refrigerant solutions
A little ammonia — tons of cooling.
Ammonia is the most environmentally friendly natural refrigerant with a GWP (Global Warming Potential) and ODP (Ozone Depleting Potential) right at zero. Yet, the inherent hazards of using ammonia to cool have resulted in a tangle of regulatory liability and personal safety concerns — until now.
The Hillphoenix® NXTCOLD™ technology has solved the compliance and hazard issues by creating an ultra-low charge ammonia industrial refrigeration system — ultra low as in 8 ounces of ammonia per ton! — in systems from 5 tons up to 150 tons.
More efficiency — More savings.
The NXTCOLD system is equal to or even more energy efficient than a central engine room system for several reasons. The use of close-coupled components eliminates a host of potential trouble spots. The system has no liquid refrigerant pump which keeps it simpler and more economical. And NXTCOLD systems keep pressure constant without pressure drops that can compromise compressor capacity and increase power usage.
Ammonia’s superior heat transfer properties add to the savings because it allows equipment to have smaller heat transfer areas — which lowers plant construction costs and reduces operating costs!
ERIC is the key.
ERIC — Electronic Refrigerant Injection Control — is a patented technology developed for freezers, blast freezers, coolers and temperature controlled environments that reduces the amount of ammonia necessary in a system to only 8 ounces of ammonia per ton! This ultra-low-charge eases regulatory liability and personal safety concerns as well as oversight and staffing needs.
A ton of choices.
NXTCOLD refrigeration systems come in four distinct series from 5 to 150 tons. They are an extremely cost-effective solution for high and low-temp applications. With the looming phase-out of HFC and HCFC systems, the timing is perfect. For new construction, for increasing refrigeration capacity, or to simply improve system performance and reduce operating costs, an ultra-low-charge NXTCOLD ammonia refrigeration system is an ideal choice.
