Classic-Line
SQ Electric Top-Loader
CLASSIC-LINE SQ electric top-loader up to 1,350 °C or 1,380 °C
KITTEC is the first manufacturer worldwide to offer square kilns without the heavy, bulky steel frame. These kilns are therefore very easy to transport, since they will fit through any door opening of 50 cm or more. With the SQ model series, you also have the possibility of extending it with an extension ring.

Features of SQ model series kilns
More special features of the SQ model series:
- Powder-coated base – in your choice of one of five colours
- Stainless steel fastening clamps, welded on – rust-proof and easy moving
- Two-layer insulation: Lightweight refractory brick + high-quality, ceramic fibre-free insulation
- Continuous mortar-free brick lining reduces cracking
- Exhaust cowl at right-hand side, protected from condensation
- Lid lock (with lockable eyelet)
- Useful handles for secure and quick transport
Variants of the SQ model series:
- SQ Plus models, in addition to the lightweight refractory brick, also contain high-quality and innovative premium insulation in the sides and the base.
- SQ S models are constructed for high current operation.
- SQ extension rings (with their own heating elements) make it possible to extend certain SQ models to have bigger firing chambers.
Optionally available:
Other available options:
- Solid state semiconductor relay (noiseless)
An electronic semiconductor relay is used instead of the electric contactor, and makes noiseless switching procedures possible during firing. - Extended maximum temperature 1,350 °C or 1,380 °C
- Hearth air inlet slide valve
- Transport castors (2 of the 4 castors have a locking brake)
- Exhaust air opening on the left instead of on the right
- Flexible exhaust pipe
- Levelling feet for compensating for floor unevenness
Additional capacity with extension rings
The KITTEC CLASSIC-LINE extension rings (with own heating elements) for the CB and SQ model series bring additional volume and therefore more space and flexibility. In this way, extending a SQ 90 S to a SQ 140 S provides additional volume of 50 l. The divisibility of these extendible or extended models makes transport through the narrowest of door openings possible (from door width of 50 cm). The extension rings are currently available for the following CLASSIC-LINE SQ kilns: SQ 90 S and SQ 150 S.
