    CAREL’s extensive experience in the humidification business has led to the development of gaSteam, the range of gas-fired humidifiers, available in models from 45 to 450 kg/h with a temperature range of -40°C to 45°C.  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.

    The exclusive design of the heat exchanger ensures very high efficiency (94-96%) and easy maintenance. Made from stainless steel, it guarantees long life 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).

    Production from 45 kg/h to 450 kg/h

    The gaSteam proposal includes a wide range of production capacities (45-450 kg/h), which can be increased considerably by connecting up to 20 units in series.

    Operating temperature from -40°C to 45°C

    gaSteam is available in the indoor and outdoor versions, designed to withstand both high temperatures and especially climates or environments where the temperatures are very low (-40T45°C (-49T113°F)).

    High efficiency (94-96%)

    The exclusive design of the heat exchanger ensures high efficiency (94-96%) and easy maintenance. Made from stainless steel to ensure a long life with any feedwater.

    Fuel supply

    gaSteam can be supplied with natural gas or LPG: the gas is selected directly in the pre-mix burner calibration software. No modifications to the mechanical parts of the unit are required to switch gas.


    gaSteam is suitable for precision applications, thanks to continuous capacity modulation from 25% (12.5%
    for UG180 and UG300) to 100% (giving a precision of up to +/-2% around the set point).
