Allow me to alert you to something I think is unique in air handling. And, it's one of our products: the F. Muller Air Handling Unit (AHU).
The AHU uses an intelligent control unit (ICU). This can be used as a stand-alone controller, or it can easily be integrated with building management systems, thanks to the built-in RS 485 connection. Interface is easily achieved in botrh new and retrofit situtations.
Programming is done directly through the controller or by using the building management system. Functions include fan blower control, PID control, adjusting setpoint, setting timer to stop/start and so on.
Intelligent control means a user can take full advantage of the in-built energy efficiency. Control precision is + 0.5˚C.
Each F. Muller AHU can be supplied with chilled water control valves, temperature sensors and motor controllers. This simplifies installation, as all that is required, after positioning, is the supply of power and chilled water to the cabinet. Hence, installation time and associated costs are reduced.
Ruggedly built, the AHU has a high strength steel or aluminium alloy structure. Dual skin construction (with foam sandwich) not only helps overall structural strength but also helps provide greater energy efficiency.
F. Muller AHUs are highly efficient and feature low-noise multi-blade centrifugal blowers for extremely quiet operation.
Finally, our units come in three configurations: horizontal, vertical and suspension types. Operatiing modes are total fresh air, total return air or fresh air return. Working range is -20˚C to +40˚C.
