Cooling controller PRACK

Overview
The pRack is CAREL's compressor rack controller for scalable, connected and more sustainable centralised refrigeration systems. Building on the pRack300 family, it preserves proven control logic while introducing a modular product architecture, enhanced connectivity and improved usability for modern refrigeration installations.

Modularity that simplifies rack design
The pRack provides the intelligence and I/Os required for each installation with hardware tailored to the application, enabling an architecture that matches real needs.

• Main board available in three hardware sizes.
• Can be combined with valve drivers and I/O expansion modules to scale with machine options and installation requirements.
• Modular I/O supports different rack configurations and reduces unnecessary complexity.

Enhanced connectivity for data-driven refrigeration
Relevant operating data is provided where and when needed to support remote control, maintenance and efficient system management. The pRack is compatible with RED enterprise solutions and boss supervisors (legacy and current). Direct Ethernet connection and an integrated web server enable remote access via CAREL commissioning tools and simplify commissioning, configuration, diagnostics and daily operation. The user interface includes clearer descriptions and a renewed set of auxiliary and generic functions for easier customisation.

Ready for HFC/HFO, CO2 subcritical and CO2 transcritical systems
The pRack family includes versions for standard HFC/HFO and CO2 subcritical systems, a transcritical variant and a universal version covering all these system types, aiding the transition to lower-impact refrigeration technologies.
