Air drying is an energy-efficient solution for all coating drying
Thanks to high drying rates and effective nozzle technology, air dryers can achieve energy efficiency of up to 80%. Energy savings are 50% compared to infra-red drying since the energy efficiency of infra-red drying is much lower, only 25-35%, which means higher energy consumption and more costs. Air dryers are also environmentally friendly -50% less fuel is burned and CO2 is produced.
In addition, air dryers require much less maintenance time and costs and offer higher evaporation capacity. The maintenance savings are remarkable since there is no need to replace IR bulbs or emitters regularly.
Start saving your energy costs with the OptiDry air drying family and PowerFloat nozzles!

Contact our expertsReplacing gas with electricity
Many paper producers are looking for ways to eliminate the use of fossil fuels in their production. How can this be achieved in coating drying?
CO2-free coating drying is enabled by using electric heating. A gas burner can be replaced with an electric heater, which can save energy at the same time. When electric heating replaces a gas burner in an air dryer and the process is optimized, energy savings are typically around 10 percent.
