Car park ventilation in West Sussex

Enclosed and underground car parks need mechanical ventilation to clear vehicle exhaust in normal use and, in many designs, to help clear smoke in a fire. We install and maintain jet fan and ducted extract systems with carbon monoxide detection and controls.

We carry out car park ventilation across West Sussex, including Chichester, Burgess Hill, Crawley, Worthing and Bognor Regis. Prices use South East rates. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it

Approved Document B sets out ventilation provisions for enclosed car parks, commonly 6 air changes an hour for normal use and 10 in fire conditions where mechanical ventilation is used. CO detection lets the system run at low speed most of the time and boost when pollution rises. Smoke control aspects are designed with the building's fire strategy and fire engineer.

Ducted extract

Traditional ducted systems where layout suits.

CO and NO2 detection

Sensors and controls for demand-led running.

Maintenance

Planned testing of fans, sensors and controls.
