StEM is a series of fully automatic, instant electric steam generators. Designed by Unical for an operating pressure up to 7.5 bar, the range includes various models with steam production from 40 to 320 kg/h (30-240 kW) and is CE marked PED 2014/68/EU.

The generator consists of one or more modules that come assembled to increase steam production. Each module consists of a tank and various accessories, with multiple resistances installed that allow to modulate the production of steam and the absorbed power.

Installation is particularly simple and fast, as only four connections are required: Power supply, steam outlet, discharge and water inlet, which can be taken directly from the water mains. The control panel is intuitive, and the interface is based on Ufly P panel. Thanks to the modular composition, the generators allow to optimize the space occupied.

Unlike traditional generators, instead of functioning with the combustion of fossil fuels, electric generators use a system of resistances which allows to generate energy for the production process, reducing emissions to zero.
