Welcome to Thermal Technologies
Australian Supplier of Furnaces & Kilns
Our range of accessories includes kiln ventilation systems, shelves and props, spyhole and vent bungs, & pyrometric cones.
Cera-Vent – Venturi Action Exhaust Fan
This model succeeded the BTC9090 & is often the preferred upgrade. It also offers the same facilities for ramp & hold time at the set temperature, but rate is in degC/hour & time in mins.
This versatile programmable controller is an ideal upgrade for any older kiln. The controller is very user friendly & provides the user with the facility to store up to 9 programs each with 8 stages.
The Sentinel controller can store up to 12 programs, each with up to 32 segments. View firings progress in graph mode. Also turn kiln vent or gas injection on or off during the firing.
The main switching device which links the controls to the heating elements – these have to work hard, switching on and off throughout each kiln firing. They provide millions of switching intervals over the kiln’s life – but eventually, they do wear out. Various sizes are available to suit all kilns.
Early model kilns which did not have the luxury of programmable temperature controllers were reliant on this device to manually provide a means of progressive variable input power. Generally used in older Woodrow & Tetlow kilns.
Pre 1972 – most kilns used J or K
1972-1982 kilns generally used K
Post 1982 most kilns used type N
Most commercial kilns are R or S
A range of support documentation and service is available including replacement manuals for kiln controllers, cone equivalent firing charts, ventilation advice, good kiln housekeeping and safety tips for the kiln room, as well as advice on troubleshooting

History of Thermal Technologies
Thermal Technologies Pty Ltd is owned and operated by Peter Geddes. Peter has a diverse background, having completed diploma studies in mechanical engineering and management in 1969 and 1973 and then moving into the specialized field of industrial control, in areas such as conveyorised paint finishing lines, high-speed steel strip paint lines and many appliance industries.
With this experience, he later found that he had developed considerable skills in the area of industrial ovens and furnaces, primarily in paint finishing and the heat treatment of steels. His furnace experience enabled him to move quickly to the design of kilns when ceramic art disciplines became part of school visual art curriculums in the early 70’s.
Eventually, in 1977 he began his own business as a furnace and kiln manufacturer in Sydney. Furnaces and kilns were offered for metals heat treatment, pottery, doll making, jewellery etc. Similarly, when Australian Universities began to expand their own visual arts programs to include art glass, Peter designed a whole range of art glass kilns for the various processes. (glass slumping and fusing, glass casting, glass annealing, recycled glass, stained glass).
Over the last 30 years in Australia his knowledge in these field has become widely respected. Peter has designed, developed and patented processes for the ceramic and glass industries, having pioneered many furnace construction techniques. Over the years, he has presented papers on glass processing at several international glass conferences.
Peter moved away from full time manufacturing in 2010, and started Thermal Technologies, now based in Queensland. The company is less industry focused and more service and repair orientated toward educational institutions and private users. Although ceramics and glass processing are still very much a part of the focus, albeit as a reseller and repairer of smaller kilns and furnaces, the same services now extend to glass bead annealing kilns, dental ceramics and knife making.
Thermal Technologies continues to seek out the best value equipment on offer around the world for its clients and provide the backup service that has been the hallmark of its success.
