ACMV, Cleanroom & Process Utilities

Air Conditioning and Mechanical Ventilation (ACMV)

The ACMV system is typically one of the largest power consumptions in an industrial building due to cooling, handling & displacing, and treating huge volumes of atmospheric ambient air. At Critical, we are at the forefront of evolving with technology and best known practices to ensure our systems provide clean, safe, & controlled working environment for our end users.
