Industrial Autoclaves

Cyclotherm SA has manufactured over 130 industrial autoclaves for the South African and international markets. Our experience has resulted in unique methods that are now standard across the industry.

Cyclotherm SA is a proud leader in the design and manufacture of industrial autoclaves in South Africa and beyond. As one of the countries most trusted autoclave suppliers, our reputation is first-rate. We’re often approached for our unique autoclave design that is suitable for electrical, dry and wet steam heating.

What makes our autoclaves stand out from other industrial autoclave suppliers in the market? Our products have an exceptional design that makes them safe and sought-after. We’ve integrated a hinged door into our autoclave design and have fitted our own loose ring door-securing device to complement it. This device promises perfect pressure retention and a long seal life. While the door-securing device rotates, the door does not, resulting in smooth operation with minimal effort. As an added safety feature, every one of our industrial autoclaves is fitted with a mechanical door safety device. This ensures that the door cannot be opened while the chamber is still under pressure. Each autoclave is lagged with fiberglass for added insulation, and comes with galvanised stainless steel sheet cladding.

Our industrial autoclaves can be built to your exact requirements and every product meets strict international standards. From design approval to inspection, procedures and methodologies, world-class quality is standard here at Cyclotherm SA.

Our team has manufactured over 130 industrial autoclaves for South African and international markets and this has added to our already exceptional knowledge bank and improved our skillset. We’re masters when it comes to workmanship, and every autoclave is made to British Standard or American Standard, including South African inspection and design approval SANS 347: 2008 – (RSA/CIF 8.1 07 A 08). Each product is issued with an inspection certificate.
