Variable air volume
Introduction to VAV & CAV
For CAV systems, frequency inverters are often used to maintain the flow independently of changes in pressure drop which occur when filters are contaminated
Flow regulation is an appropriate alternative in this case. For CAV systems with additional zones, we recommend frequency inverter operation with pressure regulation. Pressure regulation is used for VAV systems, where appropriate with flow-compensated supply or exhaust air in order to ensure balance in the system.
Frequency inverters are also an excellent tool for adjustment of the flow, and can eliminate the need to switch the belt transmission in order to change the air flow.

DOORS & WINDOWS
Clean Room Building Elements
Hinged doors, sliding doors, non-opening windows and transfer doors form a comprehensive built-in system and connect parts between individual rooms or spaces.
- An automatic drop-down seal integrated into the door leaf enhances the air-tightness of a door
- Being flush with sandwich wall partitions ensures easy maintenance and flawless disinfection
- An interlock system equipped with signaling units prevents both doors in an airlock room from being opened simultaneously, effectively reducing the risk of contamination
- Doors can be opened manually or automatically with automatic drive
- Transfer doors are used as partitions of transfer boxes (passive or with filtered airflow)
- Accessories available include automatic drives, door closers, mirrors, windows with sunblinds, windows made from float glass or safety glass (ESG, VSG), automatic drop-down seals, stainless-steel kick plates, electromechanical and electromagnetic locks, signaling panels (semaphore), and many more.
