Neptronic SKG - gas-fired steam humidifier

The Neptronic SKG has the World's smallest footprint of any gas-fired humidifier. A 100kg/h unit has a footprint of just 610mm by 560mm making it ideal for plant rooms where space is at a premium.

It has also been designed with maintenance in mind. Every steam humidifier builds up scale, when run from mains water, as the minerals present in the water are left behind during evaporation. Scale build-up in the SKG is absolutely minimised by the patented spiral heat exchanger. This unique design expands and contracts significantly during operation, which literally cracks the scale from the surface to keep the heat exchanger clean and fully efficient. The result is a marked contrast to the performance of flat or tubular heat exchangers.

Scale is either washed away during flush cycles or accumulates as fragments in the bottom of the boiling tank. Periodically, the tank needs to be removed to empty out the scale fragments. Again, the SKG’s unique design takes account of this. There’s a quick-release mechanism on the boiling tank to allow it to be lowered, removed and emptied of scale in less than five minutes. It also makes manual handling safer and minimises the space needed around the unit for maintenance.

 Features
  • Smallest footprint for any gas-fired humidifier

  • Maintenance-friendly design with quick-release tank mechanism

  • Widest modulation from a single unit (8.7-400kg)

  • Patented spiralled elements that resist scale

  • Solid state water level sensor to always maintain water levels even during foaming

  • Single point connections for water, gas, flue, drain, controls & electricity

  • High combustion efficiency (93%)
  •  Widest modulation available
    As well as being the most compact gas unit available it also has the widest modulation and highest output from a single unit.

    The largest SKG has a massive output of 400kg/h with a minimum output of just 8.7kg/h, providing excellent control over humidity even at low requirements. This humidifier still only has single connections for water, drain, gas, electricity and flue making it easy to install.
     Payback in 12 months when compared to electric steam
    Payback in 12 months when compared to electric steam
    The running costs for the Neptronic SKG are 75% cheaper than electrode boiler steam humidifiers, resulting in a payback of around 12 months when replacing existing electrode boiler units. This graph shows the payback of a 180kg/h system when compared to the equivalent electric steam humidifier.
