Since the early 1900’s, the Simons name has been synonymous with Australia’s thermal engineering and refrigeration industries.Through continual innovation, Simons Boiler Co. has evolved in response to the ever changing needs of the industry


Artisan carpenter, Woolf Simons began the business making ice chests in the days before refrigeration, and with sons Asher, Percy, and Sol founded Simons Boiler Company in 1932


In the late 1930’s, Asher Simons, a mechanical engineer, invented a new way to press clothes using an electric iron with a small steam boiler. The invention of the Simons iron was an instant success and later became part of Australia’s War effort pressing military uniforms.

In the 1940’s, the World War II hit Australia, and Simons began producing gas-fired boilers and air compressors in response to the call of the war effort


In the 1970’s the discovery and exploitation of natural gas brought demand for gas boilers and coincided with third-generation engineer Robert Simons entering the business. Since then, Simons’ have continuously been expanding their portfolio of allied steam and hot water products partnering with world wide manufacturers such as Vapac, Trevil, ICI Caldeie, Rapak and Edwards.
