V3 series-centrifugal fan type

Centrifugal fan- V3T and UDSBD type which can be provided with a centrifugal pressure fan are installed in a horizontal or vertical downward air distribution system. Altogether nine specifications are available with a heating capacity ranging from 15 to 64KW.
  • Mounting allows the fan of the heater to supply air vertically (in a downward direction) to reduce heat loss caused by roof and avoid thermal stratification;
  • One temperature controller can be installed to serve as a turbulent flow fan. After the indoor temperature reaches the desired value, the fan heater will stop blowing automatically and blow the hot air near the lower part of roof to the ground to reduce energy consumption and improve environment comfort;
  • A direct-coupled centrifugal fan can provide as high as 150Pa of effective outlet air static pressure and 3 kinds of air distributors — shutter air distribution boxes are available with horizontal and vertical air distribution shutter. The downward air distribution box is provided with a shutter.

    Note:

    (1)The category of the exhaust methods for fuel gas fumes can be treated according to the CEN report, CG1749-2001;
     (2)The installation height of the fan heater is recommended by the manufacturer and different use and installation requirements vary the planned use of the fan heater. The operation and efficiency of the fan heater are also affected by a number of external factors, such as other air treatment equipment, barriers along the intake path, cross ventilation and the doors and windows of an enclosed building. Efforts will be made to make the installation height of the fan heater exceed the recommended value, unless a downward air distributor is used. Otherwise, indoor air may become stratified, reducing the effective distribution of air and may obviously increase the thermal loss generated by roof structure;
     (3)This refers to the place where the ambient air temperature is 20 C, the air distribution shutter is 0  and the air velocity is 0.5m/s under isothermal working conditions;
     (4)dB (A) is the value at 5m distance from the fan heater in the reference environment where A=160m2 and Q=2;  (5)dB (A) refers to the open space which is 5m from the fan heater;
     (6)dB (A) is measured on the basis of 150Pa pressure of air outlet.
