U.S. refrigeration contractor Rufus Brubaker Refrigeration has installed a 200TR (703.4kW) transcritical CO2 refrigeration system for a customer in Pennsylvania — a solution including parallel compression and heat reclaim for hot water production.
The system was designed for process refrigeration and manufactured by Zero Zone. The end user has not been named.
The system has a 150TR (527.5kW) medium-temperature capacity and 50TR (175.8) low temperature, and was installed indoors. It is equipped with parallel compression, adiabatic gas coolers and hot gas defrost. The system also has heat reclaim, which the customer utilizes for hot water production.
“Rufus Brubaker is a longtime customer of Zero Zone,” explained John Collins, Industrial Sales Manager – East for Zero Zone. “When they made the decision to pursue CO2 refrigeration for their customer, they came to Zero Zone as a trusted partner to deliver a successful project.”
“Our team worked closely with Rufus Brubaker all the way through design concept, fabrication, installation, and start-up to assure a smooth project delivery and satisfied end user.”
Zero Zone sees CO2 “growing increasingly important to the refrigeration industry” in the U.S. and ever more suitable in all kinds of climates. “Improvements to CO2 transcritical technology make CO2 feasible and reliable in more regions, including Pennsylvania where this new system is located.”
The company believes that there are many reasons why contractors and end users should choose natural refrigerants. “CO2 is one of the safest refrigerants to use,” the company said on its website, adding that “Both CO2 and ammonia as refrigerants are readily available, and of course, the biggest benefit to natural refrigerants is that they are environmentally sound and meet global sustainability goals.”
