The Carel pRACK pR100 series of controllers is designed for the complex management of condensing units and compressor systems. This series is available in five sizes in various equipment versions with built-in or external PGD1 terminal or built-in RS485 interface. The user-friendly interface makes it easy to configure the controller and the extensive range allows flexible adaptation to installation requirements. The pRACK pR100 controllers are equipped with solutions to facilitate configuration for different types of compressors (screw, reciprocating, and scroll compressors). They can be integrated with supervision systems from the boss family and remote control systems, providing optimal monitoring for retail applications.

Ideal for most standard applications, the pRACK pR100 controller is distinguished by its ability to adapt its functions to the type of system and characteristics of the electrical panel.

All pRACK pR100 models are equipped with: opto-isolated pLAN input, black cover, maximum number of available SSR relays and connector set.

Key features that have enabled the pRACK controller to achieve a high position in compressor unit management in the retail sector include ease of use, full system type configurability, and maximum input/output availability, in particular:

  • Wizard: a step-by-step procedure guiding the user during controller configuration
  • Double line: pRack can completely manage an entire low-medium temperature system on one single controller. In addition to the traditional configurations with one suction line and one condensing line, two suction lines and two split or shared condensing can be managed.
  • Multiboard layout: the flexible pRack architecture means several controllers can be connected together to make up a single control unit for managing up to two complete systems.

Characteristics of Carel pRACK pR100 controllers:

  • Various equipment versions: Compact, Small, Medium, Large, Extra large
  • Up to 6 analog outputs (depending on the version)
  • Up to 18 (29) digital outputs (depending on version)
  • Up to 10 analog inputs
  • Up to 14 (18) digital inputs
  • Available with built-in or external PGD1 terminal or built-in RS485 interface
  • Support for reciprocating, scroll, digital scroll and screw compressors
  • Generation of user-configurable functions (ON/OFF, modulation, alarms, time ranges)
  • Carel and Modbus communication
  • Heat recovery, ChilBooster

Advantages of Carel pRACK pR100 controllers:

  • Operation of up to two independent suction lines and two condensers
  • Innovative management algorithms for energy savings
  • Support for up to 12 scroll or reciprocating compressors per system, up to 2 screw compressors per system (maximum of one system with screw compressors), up to 16 fans per system
  • Faster operation thanks to new technology based on pCO 5+ controllers
  • Easy to operate; has numerous technical details, procedures, and tools to help users when using the control unit
  • Modulation and energy saving
  • Multiboard layout - pRACK boards can be combined with each other in a very versatile way to serve different unit configurations available on the market
