Combustion gases, steam, or electricity can all be used to heat the water bath. Ready for use right away, a bundle of stainless steel vaporising tubes is immersed in the water bath. To keep the bath's temperature constant, the heat entering it is managed. If planned downtime in a freezing condition is anticipated, a glycol mixture may also be utilised. Nitrogen, oxygen, argon, carbon dioxide, ammonia, chlorine, ethylene, and LNG are just a few of the cryogens and liquid gases that can be vaporised using water bath vaporisers.
