The oldest and best-known method of evaporating water is heating water to a boiling point of 100°C. This can be achieved in various ways:

– Electrode conduction: this is the conduction of electricity through water. The electrodes are located in a plastic container in which the water is heated. The electrode humidifiers are cheaper to buy, but more expensive to maintain, because the vessels have to be replaced regularly.

– Resistance or elements heating: this is placing one or more heating elements in the water. This is often done in a cleanable cylinder or tank made of stainless steel. The resistance humidifiers are more durable and cheaper in maintenance and water consumption. 

– Heating by gas burner/flue gas: Water is heated by a gas flame contained in a metal housing and submerged in water. The gas-fired humidifiers are often used for larger capacities and in locations where there is a high moisture demand, because it reduces the CO2 footprint of the company. O because the electrical connection is too light.

– Heating by oil or superheated steam: available steam nets are used to boil water directly or indirectly. 

Below you will find an overview of the hot steam humidifiers that we supply.
