The BT 300/13 Shaft Furnace from the BT series has a volume of 300 litres and is suitable for temperatures up to 1300°C.

This series combines 5-side heating in a robust chamber furnace construction with all the advantages of a toploader. The high-quality insulation structure and the even temperature distribution make the shaft furnace suitable for applications where as many goods as possible must be placed and processed in one firing process. The shaft furnace offers an excellent overview during charging.

The in-frame ventilated lid and the use of galvanized steel sheet in the furnace casing provide effective protection against corrosion. Another feature of this design is the carefully manufactured furnace lid. It is provided with a gas pressure spring that allows easy opening of the lid. KANTHAL heating elements have been calculated with minimal surface load to minimise wear and to ensure a long service life.

Torsion-resistant welded steel housing

The housing consists of a torsion-resistant welded construction. Each furnace is manufactured by hand and leaves the factory after undergoing extensive quality controls.

Durable textured paint finish

The high-quality light-grey RAL 7035 textured coating protects the furnace body and steel construction.

Safe lid opening thanks to the robust lid

The lid comprises a robust lid hinge and a gas pressure spring allows for easy lid opening.

Air supply handle

The manual air supply handle ensures the best possible ventilation of the furnace interior.

Exhaust air flap handle

The manual exhaust air flap handle is available for the controlled removal of gases and hot exhaust air.

Efficient 2-layer insulation structure

A sophisticated 2-layer insulation structure allows for required temperatures to be achieved using less energy. High energy efficiency can be achieved even in continuous use.

First-class useful volume

All insulating materials are processed precisely and carefully. Lightweight firebricks in the firing chamber are characterised by a high insulation value and good thermal shock resistance.

Covered heating elements on the floor

A high-quality SiC plate protects heating elements mounted on the floor. The SiC plate guarantees good heat transfer and at the same time protects the heating elements from damage.

Easy-to-maintain switchgear mounted in a connection box

The switchgear is mounted in a stainless steel connection box and can be easily maintained and accessed.

Integrated safety due to door contact switch

A door contact switch automatically isolates the heating elements from the power supply when the kiln opens. The integrated overtemperature protection prevents damage to electrical components.

Low-wear contactors for control

The furnace is controlled by low-wear, durable contactors.

5-side heating allows for good heat distribution

Heating from 5 sides (side walls, back wall, door and floor) results in very good heat distribution throughout the firing chamber.

Durable heating elements made of “Kanthal A1”

We are committed to minimal surface load and precise manufacture when dimensioning “Kanthal A1” heating elements, so a long service life is guaranteed.

Heating elements securely recessed into bricks

Heating elements are recessed in protected position into bricks and achieve high energy input and provide ideal protection against mechanical damage.

Heating elements can be easily accessed and serviced

An easy-to-access detachable cover for heating element connections allows the effortless replacement of heating elements.

Precise temperature measurement with the “Type S” thermocouple

The installed PtRhPt thermocouple (type S) is protected against damage and guarantees exact temperature measurement at all times.

The “CEE 32 A” connector allows for easy connection

The standardised CEE 32 A connector allows for easy connection and quick and safe start-up.

Components from well-known manufacturers contribute to long service life

We only obtain our electric components from well-known manufacturers (e.g. SIEMENS, MOELLER, WEIDMÜLLER, RITTAL).

Furnace construction in accordance with DIN EN 746-1

The unit is constructed and manufactured in accordance with DIN EN 746-1 Industrial Thermoprocessing Equipment.

Switchgear design in accordance with DIN EN 60519

The switchgear is designed in accordance with DIN EN 60519 Safety in Installations for Electroheating.

2-year warranty despite intense use

We deliberately refuse to reduce the warranty period despite commercial furnaces being used intensely except parts that are subject to wear.
