Industrial Furnace Manufacturer

Caltherm have many years experience of designing and building industrial furnaces, from simple front-loading furnaces to automated furnaces operating at 1300OC.

 

All Caltherm's furnaces are designed and built to suit.  If you have a straightfoward batch requirement or a challenging heat-treatment process that also needs material handling, talk to us - we are here to listen.

We will come up with ideas and listen to yours.

Titanium Heat Treatment Furnace Titanium Heat Treatment Furnace

Caltherm's small batch furnaces are designed for rugged industrial environments, with vertical doors, they can be safely opened at their maximum tempeartures.

Typical options:

  • Controlled cooling
  • Programable time temperature control
  • Guides for fork trucks
  • 9-point temperature survey with calibrated instrumentation (Nadcap TUS)
  • Paperless chart recorders
Conveyor Furnace and Water-Spray Quench for Heat Treatment of Stainless Steel Conveyor Furnace and Water-Spray Quench for Heat Treatment of Stainless Steel

Using nickel-alloy belts, conveyor furnaces are ideal for high-volume heat treatment, giving repeatability through consistent times and temperatures.

Example features:

  • Air quench
  • Water quench
  • Polymer quench
  • Controlled cooling
  • Return conveyors
Combined Mould Preheat and Controlled Cooling Furnace with Bogie Hearth Combined Mould Preheat and Controlled Cooling Furnace with Bogie Hearth

Roller or bogie hearth furnaces allow for overhead handling of heavier loads, using brick hearths to carry the weight. Heating uniformity is achieved through zone control of the heating elements, with heating elements in the hearth to improve heat transfer efficiency.

Semi-automatic Loaded and Unloaded Drying Oven and Firing Furnace Semi-automatic Loaded and Unloaded Drying Oven and Firing Furnace

Caltherm design and build product handling to suit production volumes and techniques. We can combine ovens and furnaces into a complete production system, typically offering:

  • Tray handling vis push-pull
  • Basket lifting and shuttling
  • Accurate positioning for robotic handling
  • High-speed transfer to quench

Pusher Kiln, with hydraulic press, for processing spark plugs.

Completely designed and built by Caltherm, the push mechanism, door gear and product press are operated by hydraulics. The whole system was built in our works and product was produced, witnessed by the customer, to minimise installation time on site. It includes:

 

  • Allen Bradley PLC control with HMI
  • Solid-state switching of the heating elements
  • Rapid cooling at the press, via a high-pressure blower
  • Accurate positioning for robotic load and unload of components
  • Kiln temperature uniformity of +/-5OC of set-point
3D Model of Small Batch Brazing Furnace Small Batch Brazing Furnace

Caltherm design and manufacture small batch brazing furnaces, using a retort mounted inside a circulating air oven that rises off a heated hearth.  The automatic raise and lower mechanism allows easy loading access and an all-round seal when the furnace and retort is lowered onto the hearth.  A sophisticated control system gives fully automatic operation from closing the safety gate, to opening it to unload. With oxygen instrumentation, heating and cooling is optimised to minimise nitrogen consumption.
