CLU Chamber Kilns
INDUSTRIAL-LINE model series CLU circulating-air chamber kilns up to 850°C
The KITTEC CLU kilns have a frame made from powder-coated sheet steel and an interior made from stainless steel. They are perfectly designed for stress relief annealing, tempering, precipitation and keeping warm.

Features of model series CLU
Further features of model series CLU:
- Short heat-up times
- Temperature distribution within the usable space ±5°C (with soaking times of > 30 minutes), based on DIN17052
- High-quality and energy saving insulation using mineral fibre boards
- Horizontal air circulation
- Powder-coated steel frame
- Stainless steel interior
- Stainless steel side panels with rear ventilation for low outside temperatures fulfill the industrial standards
- Heating system with long service life
- CLU 15 comes as a table-top model, all others with removable pair of legs for easier transport
Optionally available:
Further available options for model series CLU:
- PC connection including WinControl professional software
- Protective gas connection
- Semiconductor relay (noiseless)
An electronic semiconductor relay is used instead of the electric contactor, and makes noiseless switching procedures possible during firing.
