Electric steam generator EL7

Electric steam generator, 99% efficiency (1).

EL7 is an instantaneous electric steam generator. Designed for a working pressure of 4.5 bar (8.5 bar upon request) and a steam production from 20 up to 250 kg/h (15 – 180 kW). The conformance to the essential safety requirements demanded by the European Pressure Equipment Directive 2014/68/UE (PED) is guaranteed by the CE mark. 

Design features

The steam generator is composed of one or more pressure vessels having a variable number of electric resistors on board. Such configuration allows the generator to modulate the steam production and the absorbed power.  

Installation of the generator is as quick as easy because only 4 connections are necessary: electric power supply, steam supply, drain and water inlet. Water feed can be connected directly to the water mains or to a condensate tank. The control panel manages automatically the steam generator and has an intuitive operational. Because of the vertical design, the EL7 has a very small footprint.
