Cotes Ultradry Adsorption Dehumidifiers
If you want to make sustainable batteries, you need sustainable battery production. Lithium-ion battery dry rooms use a lot of energy and represent over 43% of the total energy used in the battery production process. With Cotes Ultradry adsorption dehumidifiers, you can stop using gas, cut that energy consumption dramatically and source the remaining energy from sustainable energy sources.
Cotes, the right way to dry.

What is your prefered nominal operating dew point inside your dry room? Cotes Exergic Technology can reach dew points of -120°C in an unstaffed room, though we see most dry rooms only need to maintain a dew point of -60°C.
Based on your data Cotes Exergic Technology can provide you with the following:
-

Compare Cotes Exergic with the competition
The issue with current non-Cotes dehumidification is their high dependency on only electricity and gas. Cotes Exergic Technology allows you to choose a combination of sustainable energy sources like:
- Waste heat (District heating or waste heat from elsewhere in the li-ion battery production)
- Biomass or Biogas (if available and sustainable)
- Solar thermal panels
- CO₂ Heat Pump used for both heating and cooling. Pay once and use twice.
- Electricity (From sustainable energy sources, i.e., wind power, hydropower, solar power and/or nuclear power)
Depending on your sustainable source of energy to heat the hot water in Cotes Exergic Technology, you can save up to 66% on your dry room energy bills and reduce up to 95% of dry room CO2 emissions.

The right way to dry a battery dry room
Cotes is an independent family-owned business that designs and manufactures adsorption dehumidifiers [dry-air solutions] for all types of industrial applications across the world, focusing on sustainability, efficiency, quality and positive impact.
Lithium-ion battery dry rooms use a lot of energy. Up to 43% of total energy consumption in the battery manufacturing process is for keeping the dry rooms super dry—that's a relative humidity of under 1% and dew points ranging from -40°C to -120°C.
Cotes offers an Ultradry-air Solution for battery dry rooms that uses our Cotes Patented Exergic Technology, enabling massive energy reductions, cost savings, and huge CO₂ emissions reductions of up to 95%.

Cotes Exergic Technology
Choose a combination of different sustainable energy sources
The issue with current non-Cotes dehumidification is their high dependency on only electricity and gas with very ineffective air-drying processes at high temperatures makes for a volatile and unsafe process environment. Cotes Exergic Technology gives you a competitive advantage by saving up to 66% on your dry room energy bills, reducing up to 95% of dry room CO2 emissions, and an ultradry system that operates at an extremely safe low dew point as low as -120°C.
How it works
With the Cotes Exergic Technology, you can utilize a combination of sustainable energy sources to achieve considerable energy cost savings and large carbon footprint reductions. All you need for Cotes Exergic Technology to work is hot water heated by a sustainable energy source:
- Waste heat (District heating or waste heat from elsewhere in the li-ion battery production)
- Biomass or Biogas (if available and sustainable)
- Solar thermal panels
- CO₂ Heat Pump used for both heating and cooling. Pay once and use twice.
- Electricity (From sustainable energy sources, i.e., wind power, hydropower, solar power and/or nuclear power)
- Gas **
**Cotes does not recommend or consider gas as a source of sustainable energy due to the environmental footprint. We recommend utilizing energy for the hot water from sustainable or “green” energy sources instead. However, if gas is a requirement, the water can come from a central gas boiler.

Why use hot💧water?
Cotes Excergic Technology uses hot water because it enables flexibility, makes your dry room operations safer, and has low installation costs—all you need is hot water [80-90°C].
Because the energy to heat the water can come from a combination of sustainable energy sources and can be changed in the future if the price of energy changes, it makes the Cotes Exergic Technology more sustainable and more future proof. This flexibility is not possible if the dehumidifier is built for gas regeneration specifically.
Cotes Exergic Technology is highly efficient. We are able to provide a dew point of -120°C for an unstaffed dry room and -70°C for a manned room.
The Cotes Exergic Technology is less vulnerable to toxic leaks and has a high safety margin running nominal conditions at low temperatures. Running optimal conditions at low temperatures (80-90°C) allows the electric booster inside the dehumidifier to increase the drying capacity when needed without jeopardizing the effectiveness or the safety of the system. Our closest competitors run optimal conditions at maximum temperature (140-180°C) making it vulnerable to any fluctuation in humidity and drying capacity.
