Carel Controllers and DAP Series Replacements for CRAC Systems

CRAC Parts and Service is now the official, exclusive distributor of Carel controllers and Carel DAP controllers designed for use in Data Aire CRAC systems and other precision cooling environments. Whether you’re replacing a failed controller or upgrading an outdated interface, we offer reliable solutions for system diagnostics, airflow management, and temperature control.

Our inventory includes Mini Data Alarm Processors (MiniDAP4s), and full Data Alarm Processors (DAP4s) fully configured for compatibility with Data Aire equipment as well as retrofit kits for legacy models like DAP 2 and DAP 3. These factory-supported controls ensure smooth integration with your CRAC unit’s logic and communication protocols.

Every controller is configured and programmed for use on specific Data Aire CRAC units and is tested and backed by technical support to help ensure fast installation and reliable performance. If you’re unsure which Carel controller fits your system, our team is here to help you select the correct model based on your unit’s specifications.

To obtain a quote on the DAP4 controller retrofit kits, please provide the Data Aire unit model number, serial number and job number off the unit ID tag. In addition, any numbers off the controller itself are useful, and knowing the software version is sometimes critical. This is visible on the display.
