Pressurized rooms and fume hoods
Desigo room pressurization and fume hood control is a range of dedicated,
reliable air volume flow controllers and supplementary components for
secure, precise and fast measurement, control and monitoring of air
volume flows and room pressures in highly specialized working spaces.
It is part of the Desigo building automation and control system.
As a result, the overall system maximizes security, efficiency and cost-
effectiveness.
Locations:
• Highly specialized research and manufacturing spaces requiring
dedicated high-speed control solutions for room pressurization & fume
hood control
• Rooms in:
– Research facilities
– Pharma/Biotech
– Healthcare
– Hi-tech manufacturing
– Vivariums
– Higher education customers, etc.
Applications:
• Room ventilation and general extraction, measuring, controlling and
monitoring of air volume flows
• Room balancing and room pressurization control
• Laboratory fume hood air volume flow control and monitoring
• Room air conditioning together with lighting & shading control
• Room and fume hood emergency functions
• Demand-controlled ventilation support for energy-saving opportunities
• Pressurized rooms and fume hoods
– Application works self-contained or distributed across multiple
automation stations.
– 1 room segment control (30 data points)
operates one supply and one extract terminal or one fume hood,
as well as coordinates operation among multiple room segments.
– 2 room segment control in single automation station
(60 data points)
operates two supply and two extract terminals or one fume hood,
as well as coordinates operation among multiple room segments.
• Variable (VAV) and constant volume flow
– with 2-stage electric heating
– with hot water
– with hot water and flow temperature control
– with hot water and thermal power control
• Separate temperature and volume set points for all 4 operating modes.
• Supply and extract air flow tracking
• Room pressure cascade control
• Accepts external demand control ventilation signal
• Chilled water and hot water valve
• Chilled beam active or passive cooling (2-pipe) or cooling/heating
(2-pipe) or cooling/heating (4-pipe)
• Radiant ceiling: cooling, cooling and heating (2-pipe) or cooling/heating
(4-pipe)
• Radiator: hot water, steam (2- or 4-pipe) or electric stepped controlled
• Light: up to 4 separate zones
• Blinds: 1 or 2 motors
