Helo Steam Generator Logo


Helo's new AK generators were purpose-designed for home use, transforming your shower or bathing room into a daily invitation to comfort.

An AK generator uses full power to quickly heat up the steam room to it's pre-set temperature, then cuts the power by 1/3 or 2/3 of its heating elements. The result is a more consistent flow of steam and more stable temperature.

Available in 4 popular sizes - 4.5kW, 7.5kW, 11kW and 14kW.  

Helo have been producing steam generators for the home and health clubs for more than 30 years. Built without compromise, should attention ever be required Helo engineers and genuine parts are always available to keep your steam room in service.
