An HVAC manufacturer approached the Hillphoenix Industrial engineering team with a complex request.

The company needed a refrigeration system capable of sustaining temperatures of -5°F or 30°F to simulate outdoor conditions. It would also need to withstand temperatures of up to 140°F when shut off during high-temperature simulation.

The Hillphoenix team spent weeks with the end-user exploring all the system requirements and necessary transitions. This research, combined with years of experience with CO₂ systems, enabled our engineers to design the ideal system to handle the level of variation this application required. The equipment consisted of a 200-ton low-temp (-15°F) and medium-temp (20°F) transcritical CO₂ system and an indoor rack.
