Exhaust air-free drying with heat pump
Our passion is to find the best drying solution for you and then realise it. We have over 30 years of experience in the construction of drying systems at our disposal - and a highly motivated team with a passion for innovation.
So much
We have realised over 2000 projects and made many customers happy in the process. "At last my products are dry" is a statement we hear time and time again. And of course it's about much more than that. It's about making processes safer. It's about gently dehumidifying products. It's about finally being able to adhere to cycle times or, in many cases, to shorten them. It's about drying without exhaust air in a closed system. It's about low temperature, efficiency and safety. Sometimes it's about developing new processes. Sometimes it's about developing new products.
And today - finally - it's also about energy and CO2. Today, everyone knows that a heat pump is energy-saving and efficient. It is the centrepiece of every drying system. Many of our customers save up to 75 % of energy with it. That's a lot!

So good
