Variable volume flow controller for room supply / exhaust air and fume cupboards

To achieve stable air conditions in a room while at the same time maintaining the necessary air change rate, the specified direction of flow, if applicable, a certain room pressure and temperature control, all constant and variable exhaust and supply air volume flows must be measured and exchanged between the individual components of the system solution.

For this purpose, the volume flow controllers of the TVLK, TVR, TVRK, TVZ, TVA, TVJ and TVT type are combined with electrical control components based on the TCU-LON-II controller. The information exchange between the controllers takes place on the globally standardized LON bus and manufacturer-independent standard network variables (SNVT).

Advantages of the LON bus communication system

Minimum wiring expenses in comparison with conventional technology
Use of the LON infrastructure across various disciplines
Cross-manufacturer system components can be used
Simple integration of modules in a high level centralised building control system
Implementation of central operating mode switching and alarm forwarding
Centralised access to all modules for visualisation and configuration
Maximum flexibility in regard to expansions

LON technology is therefore particularly suitable for large-scale projects.
