SRV-EC fans are distinguished by their operational reliability, energy saving and low noise. Thanks to the use of highly efficient EC motors and intelligent automation that is built in the case of the fan, the unit allows you to maintain a set pressure, and depending on ambient temperature to change air volume, in this way ensuring independence of work of the exhaust unit all year round.
The case of the fan upon the customer request can be made of galvanized or stainless steel. Has a vertical air outlet.
Low-noise EC-motors with an external rotor of ZIEHL-ABEGG brand (Germany) or EBM papst (Germany). The motors are equipped with an electronic protection system of motor overheating.
The built in the roof fan case intelligent automation, in a board of a protection class IP64, gives the chance not to take out a control panel on a heating technical floor, hereby provides economy of the place, simplifying installation and commissioning of the fan. In some cases, automation upon the technical task can be installed separately. The fan works in the independent mode, constantly maintaining the set pressure.
* Scope of supply of the group of fans can include the panel for commissioning.
These parameters can be changed and programmed at the factory.
When the dampers in the apartments are closed, the built-in automation recognizes the change in the ventilation duct and regulates the air volume and fan power consumption, maintaining the pressure in the system.
