Close Control HVAC Services

Close Control Systems are specifically designed for data centres, computer rooms, laboratories and operating theatres where close control of temperature and humidity is essential to ensure business critical system operation and air cleanliness optimisation.

Data Centres

We have a wealth of experience designing and installing close control systems in data centres and computer rooms. Often this involves project planning to keep business critical systems in use throughout the installation phase of projects.

Operating Theatres

Contamination from the environment is a huge risk in operating theatres. Understanding this risk, our specialist solutions have been developed to filtrate the air supply to minimise the risk of any air-borne contamination during surgeries.
