Tecumseh’s CRIOS Unit Cooler, paired with ARGUS remote outdoor condensing units, delivers superior efficiency, safety, and precision for walk-in cold rooms. Designed for current A1 and next-generation A2L refrigerants, it offers easy installation, enhanced performance, and regulatory compliance, ensuring reliability for diverse refrigeration applications.
Tecumseh Products Company CRIOS Unit Cooler has been engineered to deliver efficient performance, safety, and simplicity for walk-in cold room applications. It is a perfect match with Tecumseh’s ARGUS ½ to 12HP remote outdoor condensing unit portfolio. The CRIOS unit cooler portfolio caters to multiple refrigeration applications. It has been developed for both current A1-class refrigerants (R448A & R449A); as well as next generation A2L-class refrigerants (R454A, R454C, R455A), ensuring compliance with environmental standards while maintaining high operational performance.
Both CRIOS and ARGUS systems have been designed with a strong focus on performance, reliability and safety, meeting UL standards and the Department of Energy’s (DOE) annual energy efficiency requirements for walk-in coolers.
The CRIOS Unit Cooler is available with various factory installed options to meet specific customer & application requirements. An advanced electronic expansion valve (EEV) & driver option is also offered which has been designed to provide precision temperature control and integration with system monitoring solutions. The advanced EEV feature also addresses specific safety and operational requirements associated with next generation A2L class refrigerants. This feature aligns with UL and regulatory standards, making the CRIOS unit cooler ideal for efficient and safe cooling in modern walk-in cooler applications using next generation refrigerants.
Cooling capacities
The CRIOS Unit Cooler offers capacities ranging from 3,200 BTU/h to 43,2000 BTU/h, making it a versatile solution for a wide range of cold room applications. Complementing this, the ARGUS condensing units include extended XL chassis options, providing increased capacity (7 to 12HP) for larger installations and ensuring flexibility to meet diverse refrigeration needs.
Currently, both CRIOS and ARGUS systems are compatible with legacy A1-class refrigerants, delivering immediate, reliable solutions for customers operating current systems. To support the industry’s transition to more sustainable refrigerants, Tecumseh will have samples of A2L-compatible models, such as those using R455A and R454C, by Q2 2025.
This will enable customers to test and adapt these models in preparation for the 2026 deadline for new installations, aligning with regulatory shifts towards low-GWP refrigerants while maintaining performance and compliance.
