AHU for Pharmaceutical Industry

AHU (Air Handling Unit) is a heat exchange device used in HVAC systems or industrial factories, where there is a high requirement for clean rooms, such as in the pharmaceutical, cosmetic, and electronics technology industries. Nowadays, AHU systems are widely used in commercial buildings and large shopping centers with central chiller systems. It can also be understood as a pre-processing device, similar to PAU, located in areas like corridors or large halls.


AHU is considered as the heart of clean room systems, applied in operating rooms, pharmaceutical and health supplements production rooms. Therefore, INTECH has built a factory that complies with GMP and ISO standards, equipped with advanced control technology to help factory managers easily monitor the “heartbeat” of their facility.

INTECH will help customers address concerns regarding clean room equipment and technology for GMP and ISO projects.

One of the outstanding features of INTECH Air & Clean Tech’s AHU is its durability, less proneness to breakdowns, and much more competitive price compared to directly imported AHUs from Thailand or South Korea.
