Electric boilers are very efficient. They are compact (miniature) and require no venting. Dry steam is discharged directly from the electric boiler for a quick, efficient operation. The saturated steam from Reimers boilers can be controlled as to pressure, which will vary the temperature and BTU transfer of the steam. Reimers offer a variety of models from 1.5 to 750kW with carbon steel pressure vessels and 1.5 to 120kW in all stainless steel design to match any steam application.
