Sanhua Standardized CO2 Unit Package for HVACR
HVACR operators can now utilize a modular, integrated controller package designed for CO2 condensing units.
Updated on Oct. 3, 2026 in Consumer Goods
Sanhua has introduced a standardized package solution for CO2 condensing units, integrating line components, sensors, electronic expansion valves, and controls. The system, which excludes compressors and fans, is designed to support both single-stage and dual-stage applications.
Why it matters
By consolidating disparate sensors and controls into a single package, this solution aims to simplify the procurement and integration process for complex CO2 refrigeration systems. This pre-integrated approach streamlines the assembly of condensing units for manufacturers and service providers.
The new Sanhua package integrates electronic expansion valves, sensors, compressor drives, and connectivity controls into a single unit. It serves both single-stage and dual-stage compressor applications.
The players
Sanhua
A global manufacturer specializing in HVACR components and integrated control systems for commercial refrigeration.
Reftronix
A technology firm providing specialized electronic controller solutions for the refrigeration and climate control industry.
The details
Developed in partnership with Reftronix, the controller features multi-modal connectivity, including RS485, Wi-Fi, and Ethernet capabilities. The system supports remote monitoring through smartphone integration and includes backup power functionality for electronic expansion valves. By offloading the component integration to a standardized kit, operators can reduce the complexity of system assembly and field-site configuration for CO2-based cooling projects.
