What are CRAC units?

CRAC Units (Computer Room Air Conditioners) are a key component of data centres. They provide cooling solutions to ensure optimal environmental conditions for IT equipment and hardware. CRAC Units maintain a consistent temperature and humidity level, ensuring the data centre’s hardware runs efficiently and reliably.


They also help to prevent hardware from overheating and ensure the protection of valuable data. CRAC Units are an essential part of any data centre, as they ensure the reliability and longevity of IT equipment.
