Different strokes for different folks
Cotes has a large assortment of well-engineered, energy-efficient, and reliable adsorption dehumidifiers that are used in all types of industries ranging from large lithium-ion battery manufacturers to your local brewery – anywhere there is a need to better control humidity.
The right dry-air solution for you depends on your dry-air strategy and that is why our dehumidifiers are mobile, modular, or purpose build to fit your business needs.

ULTRADRY
Most Sustainable Battery dry rooms
To safely manufacture lithium-ion batteries you need a relative humidity of less than 1% because of the delicate chemistry involved. 30-50% of the total energy used to manufacture lithium-ion batteries are used to keep the dry room ultradry. Cotes can reduce the dry room energy consumption by 60-95% depending on the configuration and sustainable energy source available.
With Cotes Exergic Technology you can maintain
a constant dewpoint below –70°C (max –120°C) by harvesting external sustainable energy sources like waste heat, biomass or biogas, solar thermal panels, CO2 heat pump, wind or solar power. Save millions of Euros on energy reduction and cost savings by removing tonnes of CO2 from your carbon footprint – the right way to dry a battery dry room.
