Calculate your battery dry room CO2 savings

This calculator uses dynamic energy prices and your dry room data to calculate how much energy you can save and how much CO2 reduction you can achieve by choosing the right way to dry a battery dry room.

Enter your dry room data:

1 H
8760 H

How many hours a year is your dry room operational? In other words, how many hours a year is your dry room staffed and producing batteries?


Conventional systems are dependant on ice water that requires more energy to generate. To dry a dry room you need both a heating and cooling source. What is your cooling source price in EUR/kWh?


Conventional systems are limited to either electricity and/or gas as a regeneration heating source. Cotes Exergic Technology however makes it possible to select a combination of sustainable sources of regeneration heating.


Because dry rooms operate at extremely low dew point it makes a big difference how many people work in the dry room at one time. 

-60 °C
-25 °C

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:
  • Dry air requirement
    0 m3/h
  • Annual energy consumption
    0 kWh

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 
  • CO 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) 
Cotes Exergic Technology can reduce energy consumption and costs. All you need is hot water

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.

So there is cost and then there are CO2 savings.
