Cooling data


Water is generally 16°c in and 20°c out for air cooling. Some site still use low temperature water, between 6°c to 12°c, but this often result with condensation and energy losses.
Warm water is generally 40°c in and 50-60°c out for direct water cooling equipments.

Ethylene glycol

Ethylene glycol is wildly used in industry.

Ethylene glycol is harmful and should be manipulated with care. Note that it’s “sugar” taste makes it attractive, and so, dangerous for children and animals.
