Transcritical CO2 Refrigeration System in Skagit
Nordic Temperature Control installed a high-tech Transcritical CO2 Refrigeration System for a food processing facility in Skagit County.
In transcritical CO2 refrigeration systems, often referred to as booster systems, the CO2 operates sometimes or exclusively above the critical point. Unlike subcritical systems, transcritical CO2 systems include a gas cooler to dissipate heat and utilize a high-pressure expansion valve to control introduction into the evaporator. Transcritical CO2 booster systems are the best solution for using natural refrigerants in a retail context.
As a highly qualified HVAC-R contractor, Nordic Temperature Control was an essential part of the equation to optimize the safety and effectiveness of the new system. It is rewarding to know that our HVAC technician’s efforts during this project work to maintain the highest quality craftsmanship and best practices for the CO2 HVAC-R system.

In transcritical CO2 refrigeration systems, often referred to as booster systems, the CO2 operates sometimes or exclusively above the critical point. Unlike subcritical systems, transcritical CO2 systems include a gas cooler to dissipate heat, and utilize a high-pressure expansion valve to control introduction into the evaporator.

There are a few notable benefits associated with opting for transcritical CO2. First, when compared to other refrigerants, carbon dioxide is much cheaper on a per-pound basis. For example, R-410A, a popular HFC refrigerant, averages between $6 and $8 per pound. On the other hand, we regularly buy CO2 for less than a dollar a pound.
Unlike synthetic refrigerants like R-134 and R-404A, which have Global Warming Potentials of 1400 and 3260, respectively, CO2’s is negligible with a Global Warming Potential of 1. Because of this, CO2 is often referred to as “future proof,” meaning that as regulatory agencies continue to evaluate and outlaw synthetic refrigerants due to environmental reasons, CO2 will remain a viable option.

As you can see from the images, our system was installed in the main living room. As a wall-mounted unit, our team installed it in a subtle spot high on a wall, where it will not detract from the home décor and will operate very quietly. As an added benefit, the new tenants will be able to use the
