Ravenscroft specialises in providing low velocity displacement ventilation solutions to commercial and manufacturing premises. Displacement ventilation is the perfect solution for lobbies, theatres and large public spaces with high ceilings and large air volume requirements. Thermal displacement ventilation is based on cool air supplied at low level and due to the natural buoyancy of warm air, draws fresh air into the occupied zone. This results in the occupant constantly enjoying fresh air in pleasant temperatures. Halton low velocity displacement ventilation creates a comfortable, draft free atmosphere while guaranteeing adequate fresh air for the occupants. Because incoming air is released at such low velocities, displacement ventilation is practically silent, making it an ideal solution for areas where acoustics are essential.
