One of 8 Vitalis Roxsta™ G6 R744 (CO2) refrigeration systems with outdoor enclosures, unitized with gas coolers on subframes, for a pharmaceutical cold storage facility in North Carolina. Includes 2 60-TR units for freezers (1 with heat reclaim) and 6 75-TR units for coolers.
Cold Storage
Efficiency and reliability are critical starting points. Vitalis solutions enhance capital and operational planning of modern cold storage applications, which encompass objectives such as operational safety, sustainability, managing variable loads, and mitigating long-term regulatory risks.
Vitalis Roxsta™ CO2 refrigeration systems are well-suited for operators transitioning away from HFCs or seeking to avoid ammonia or the flammability and potential PFAS liabilities of A2L F-gas refrigerants.
Especially for urban-adjacent facilities, Roxsta systems offer a compelling balance of safety, performance, and regulatory confidence.
Modular system designs support variable loads and future expansion opportunities, while avoiding the glare of increasing regulatory scrutiny.
CO2 provides long-term confidence for operators planning beyond the next compliance cycle, with the most balanced option for modern cold storage: a safe, reliable, efficient, future-ready platform that supports ESG goals and evolving regulations.
Highlights
-
Natural refrigerant R744 for lower operational and regulatory risk than ammonia or A2L options
-
Similar cost to central ammonia, but added value via isolated redundancy and common, easily stocked parts
-
Modular, multi-compressor architectures for matching capacity to real operating conditions, supporting part-load efficiency during idle periods and full performance during peak stock handling and production
-
Optional heat recovery for comfort heating or hot water production, reducing emissions
