  • 18-Month Warranty (12-Month Standard)
  • (2) Electric Heaters and (2) Heater Gaskets
  • (2) Sight Glass Tubes and (4) Washers
  • (1) Pressure Control
  • (1) Contactor

Motorized Automatic Flush and Drain (MAFD)

N/A During Start-Up before steam pressure is accumulated, the Motorized Automatic Flush and Drain option cycles fresh water through the boiler for 0-300 seconds (Factory set for 180 seconds or three (3) minutes). As old water is drained out, fresh water will be cycled in. This drain valve will not open if boiler pressure exceeds 5 psi, and the electric heaters are locked out during flush cycle.

Single Service Transformer

N/A Supplied standard with all portable steam generators, the Single Service Transformer steps down the primary high voltage to provide 120 VAC Single Phase (1Ø) to the controls; with this option, only the one (1) primary high voltage supply is required.

5-Micron Water Filter

N/A 2-stage, 5-micron water filter installed into incoming water line to reduce sediment, dirt, rust, chlorine, and even odor from incoming water supply.
Manual Low Water Reset4 N/A Manual Low Water Reset trips if the electric heaters shut-off because of a low water condition. Reset must be manually pressed to resume steam production.

Portable Mounting Includes

  • Wheels
  • Push Handle
  • Single Service Transformer Option

Water Feed Booster Pump

N/A The minimum requirement for your water pressure is the operating pressure +25 psi; if your water pressure is below this requirement, this option must be added. The Water Feed Booster Pump increases your incoming water pressure to overcome the operating pressure of the steam generator. The Pump requires a 5-150 psi water supply with a minimum flow rate of 2 gpm.
  • 1 Electro-Steam™ 100-240 kW electric steam generators require three (3) power supplies: Two (2) primary high voltage supplies and one (1) secondary 120 VAC 1Ø, 50/60 Hz supply. Each generator is custom built to accommodate two (2) supplies of only one (1) customer specific high voltage for the heaters. 120 VAC 1Ø, 50/60 Hz must also be supplied for the controls, unless the Single Service Transformer option is added.
  • 2 Calculations are based off of a 212 °F boiler feed-water temperature. Boiler feed-water temperatures that range between 60 °F and 140 °F, are approximately 80% to 90% of the calculated values shown. Boiler feed-water must not exceed 140 °F.
  • 3 Wetted Surfaces.
  • 4 A Manual Low Water Reset Button is supplied standard with every steam generator, but it is disabled. If this Reset Button is required as per your local boiler codes, simply plug the two attached wires into the PC-Board terminals labeled "Reset".
