CAREL’s know-how in natural refrigerant applications has led to the design of a new pRACK series control system, bringing the latest innovations in carbon dioxide refrigeration to the established reliability of a product developed for the management of refrigerating units.
Description:
pRack pR100T is the CAREL controller for managing AC-powered CO2 condensing units. It is the ideal solution for market requests regarding transcritical condensing systems.
A single-stage system is where the CO2 cooled by the gas cooler is first expanded through the high pressure valve, and subsequently, once in the liquid state, through the electronic expansion valve (before the CO2 evaporates in the individual cabinets/cases).
This compact solution comprises a single controller fitted with a driver and an Ultracap module, for direct management of E2V*CS valves used as HPVs and RPRVs; Carel E2V*CS CO2 valves have a maximum operating pressure of 140 bars with a 90 bar differential, and can be used in these types of applications with capacities up to 40 kW.
The scalability of the pRack platform allows the same user interface to be used for all these types of applications, with special focus on installation costs and simple operation.
