Sanhua Developed Standardized CO2 Unit Package
The new package integrates essential HVACR components into a single solution for condensing units.
Updated on Oct. 3, 2026 in Consumer Goods
Sanhua has introduced a standardized package solution for CO2 condensing units that integrates multiple critical line components. The company developed the new package in collaboration with Reftronix.
Why it matters
The integrated system simplifies the assembly of CO2 condensing units by bundling sensors, valves, and controls. This standardized approach aims to streamline the manufacturing process for HVACR components.
The package includes line components, sensors, electronic expansion valves, compressor drives, and controls while excluding the compressor and fans. The included controller supports both single and dual-stage compressor applications.
The players
Sanhua
Sanhua is an international manufacturer specializing in components for the HVACR industry.
