INDUSTRIAL-LINE laboratory kilns model series CLL, up to 1,400°C

The heating coils of the CLL laboratory kilns are on support bars. The five-layer insulation structure is the guarantee of a low energy requirement. The 5-sided heating provides optimum temperature distribution, even in the upper temperature range. The low surface load of the Kanthal heating elements leads to less wear and tear and a long service life. The housing structure with all-round rear ventilation provides excellent corrosion protection. The use of stainless steel supports this protection to a considerable extent.
The SiC ceiling plate is an absolute innovation in kiln construction: No contamination of the work for firing by brick dust from the ceiling. The steel frame is extremely robust and has a stable door mounting. The cover of the electrical connections of the door heating elements are integrated in the steel structure of the door. The frame of the kiln is provided with hard-wearing industrial lacquer in powder coating. The side panels are made from stainless steel.
