The formula for calculation of heating performance [kW] of air heater is dependant on air flow volume and the air temperature difference (between air on-coil and air off-coil, to be taken out of following diagrams) is as follows:

Qh[kW] = VL/3600 x (tLA - tLE) x ρL x cpL

Qh = heating performance [kW]VL = air flow volume [m³/h]tLA = air temperature off-coil [°C]tLE = air temperature on-coil [°C]ρL = specific weight of air = 1,2 [kg/m³]cp = specific heat capacity of air = 1,0 [kJ/kg K]

The required amount of water can be calculated with the formula:

VW[m³/h] = (Qh x 3600)/(∆tW x cW x ρW)

Qh = cooling performance [KW]VW = quantity of water [m³/h]∆tW = water temperature difference [Kelvin] (4K at 6/10°C or 6K at 6/12°C)ρW = specific weight of water = 1000 [kg/m³]cW = specific heat capacity of water = 4,19 [kJ/kg K]

Note for units type LJ, LM and CLM:Pressure loss of Air Mixing Units is calculated on base „free air“. That means, for connected duct of same cross section no additional dynamical intake losses have to be considered.

In case of pressure side connection with a ventilator unit the resulting pressure regain is bigger than the pressure loss. Therefore, no statical pressure loss needs to be considered.

Air Mixer Unit LJ and LMfor AHU with supply and extract air arranged on top of each other

Coarse Filter Unit GF

Combinated Activated Carbon Filter Unit AKCFfor elimination of dust and undesireable odours

equipped with:1. Activated carbon filter with 16 filter cartridges (bayonet fixing),2. Pocket filter, quality class F7 (EU7), length 600mmTotal air resistance of combinated filter unit is a sum of pressure drops of the filter steps 1 and 2.Therefore, the pressure loss of filter EU7 has to be added sepa-rately to below values for activated carbon filter (to be found in diagram for the respective filter module).


equipped with:3 Filter steps:2 Metal mat work filter and 1 Fibre mat filter with an exchange frame (regularly cleaning required)
