Capacity calculation You can simply calculate the approximate humidification capacity that you will need to obtain the air humidity that you desire in a certain room using the calculation module. You must enter the following data: the cubic content in m3; the ventilation in m3 per hour; the inside temperature in °C; and the desired relative air humidity in %. Press on the button 'Calculate' and the required humidification capacity is calculated for you.   cubic content of the room m3 ventilation of the room m3/hr inside temperature 10 15 20 25 30 35 °C desired relative humidity 50 55 60 65 70 75 80 85 90 95 %       required humidification capacity (indicative) l/hr (For the calculation, a winter situation with an outside temperature of -10 °C and a relative humidity of 60% is assumed.)
