How efficient are the systems in terms of energy?
One warm-air blower is able to dry up to 8 sets of work clothes. With a volume over 200.000 ltr. air per hour, your clothes will be dry in approx. 2-3 hours. The system is only switched on for a short period, rather than running over-night. Only the drying air is heated up to a moderate temperature of approx. 39 ºC, avoiding the need to generate a large amount of heat in the room. In conventional systems it is the need for heat generation that consumes a large amount of energy.
To minimize the costs of the drying process, and to limit unnecessary energy-consumption, the systems can be equipped with several automatic timers. By calculating the drying costs we recommend to assume an average of € 0,206/kW (the average price paid for 1 kW in Europe). One blower consumes on average ± 1 kW/hour. By drying your clothes 5 times a week, the total costs will be:
drying time of 3 hours × 5 sessions = 15 hrs per week
15 hours x 1 kW/h x € 0.206/kW x 52 weeks =
€ 160,68 per year
