Develops unique technology

GMC HVAC is capable of providing ducts, dampers, air inlets, fans, air conditioning and cooling with short response time. This is due to a well-equipped workshop and a large inventory, as well as certified documentation.

GMC HVAC has a long history of developing its own product series of acid-resistant ducts, dampers and other components.

The independent development efforts have resulted in a number of unique solutions and concepts, including the ventilation system Simvent, which creates a safe air-conditioned environment in drilling booths.

Cooling technology is a new venture enabling GMC HVAC to offer a professional environment for complete cooling solutions.
