Function

he heating of the water is done with electrical tube elements made of stainless steel placed in the boiler water tank. The tube elements are electrically connected in groups, which by relays, gradually turn the power on or switch it off, thus sustaining the necessary power.

The boiler regulates the power in accordance with the adjusted preset value for the outgoing steam pressure. Replenishment of water is done with a feed pump which is controlled by level guards submerged into the boiler vessel.

The vessel is manufactured and approved in accordance with valid pressure vessel standards and can also be supplied in ASME performance for an additional charge.
