gaSteam is the result of CAREL's extensive experience in the humidification sector.

The exclusive design of the stainless steel heat exchanger ensures very high efficiency (94 - 96%), easy maintenance and a long life. gaSteam runs on natural gas or LPG, and is fitted with a sophisticated built-in electronic controller that can also manage other types of gas by simply setting a number of burner calibration parameters. even in heavy-duty operation. The price gap between gas and electricity makes gaSteam the ideal choice for more high load applications, where steam is required many hours a day, allowing savings in the thousands of euro per year.


Continuous modulation of steam flow-rate means the appliance is also suitable for precision applications. gaSteam can operate on drinkable mains water or demineralised water (R.O.). Easy to install, it features a room-sealed combustion chamber with premix burner, and gas valve with double mechanical closing; furthermore, it is fitted with multiple safety devices and comes with ETL and CE certification (issued by TÜV-DVGW).


It is available in capacities of 45, 90, 150, 180 and 300 kg/h and can be delivered for indoor or outdoor installation.
