CAREL Unveils New pRack for Refrigeration Racks

CAREL is set to showcase its latest innovations at Chillventa 2026 in Nuremberg from October 13 to 15, centering on the theme of "Tangible sustainability." A major highlight is the launch of the new pRack, an advanced controller for refrigeration racks that builds upon the pRack300 family. The new pRack introduces an upgraded modular architecture and enhanced connectivity, allowing the system to adapt to specific installation needs. Featuring Ethernet connectivity for remote access via APPLICA Desktop or an integrated web server, it simplifies commissioning, maintenance, and daily plant management. The controller supports various refrigeration systems, including HFC/HFO, subcritical CO₂, and transcritical CO₂ architectures, ensuring regulatory compliance and greater efficiency.

Alongside the pRack, CAREL will display integrated solutions for residential heat pumps designed to boost efficiency and reliability using natural refrigerants like R290. The showcase also features Heos Pro, a high-efficiency solution for plug-in and semi plug-in refrigeration units. Heos Pro integrates continuous modulation and connectivity, supporting natural refrigerants such as CO₂ and propane to reduce emissions. These technologies allow commercial refrigeration systems to operate independently, adapting to real-time conditions to meet stringent sustainability requirements.

Additional Context
This section provides technological and market background not explicitly detailed in the original release.

The HVAC/R industry is undergoing a massive shift toward natural refrigerants, such as R290 (propane) and CO₂, driven by stringent European F-gas regulations aiming to phase out high-GWP (Global Warming Potential) synthetic refrigerants. Controlling these natural refrigerants safely and efficiently requires complex, highly precise modulation algorithms, which is where edge-computing controllers like the pRack and Heos Pro play a vital role. Furthermore, as centralized refrigeration and distributed units become increasingly digitized, integrating robust remote monitoring and data-driven supervisor systems (like CAREL's boss or RED enterprise solutions) allows facility managers to optimize energy consumption and proactively maintain assets, effectively reducing the total cost of ownership while meeting demanding environmental targets.
