The KE 250 N Chamber kiln has a volume of 250 litres and is a kiln from the KE-N series suitable for temperatures to 1300°C.
ROHDE Chamber kilns from the KE-N series comprise six models with kiln volumes between 100 and 480 litres. The heating elements are recessed into grooved firebricks on all five wall sides.
The KE-N series has been designed for use in workshops and schools. The heating elements in this series have been recessed into grooved bricks. This results in a variety of advantages. The heating elements are protected while the kiln is being charged, power output is constant and heat is evenly distributed throughout the firing chamber, providing the best possible results.
Special features of the KE-N series:
- 5-side heating resulting in even heat distribution
- Heating elements recessed into grooved bricks
- Stainless steel in-frame ventilation resulting in low external temperatures and corrosion protection
- 3-layer insulation structure
- “System ROHDE” R-SiC ceiling support prevents cracks and particles falling from the ceiling onto the ware

Long-term application temperature Tapp 1240°C
The kiln is designed for long-term and continuous use at temperatures up to 1240°C which makes it suitable for applications such as bisque, earthenware, onglaze and stoneware firings. These applications correspond to Seger Cone 6a or Orton Cone 6.
Cognitive Connectivity with the ROHDE myKiln App
This kiln can be connected to the ROHDE myKiln app using the included controller and enjoy all the advantages of the "digital firing program".
Power supply through a "CEE 32 A 5-Pol." plug connection
The standardised CEE 32 A connector allows for easy connection and quick and safe start-up. With this plug connection, furnaces with an output of up to 22 kW can be operated.
High-quality heating elements
With the heating elements made from "Kanthal A1" we attach great importance to a low surface load and a careful production. The heating elements are reliable and durable thanks to a sufficient reserve capacity in the calculation.
Careful sealing of the door
The seal between the door and the outer bricks is ensured by a flexible insulating cord. This insulating cord closes the high-quality polished sealing surfaces in the cooler area around the front row of bricks and reduces the escape of thermal energy and radiation.
Air supply slide
The fresh air supply into the firing chamber can be regulated manually with the air supply slide installed as standard on the underside of the furnace. Among other things, this removes residual moisture and combusted substances from the firing chamber or accelerates the cooling phase. In some models, the air supply slides can optionally be equipped with a servomotor and can thus be controlled automatically via the furnace control.
Exhaust air flap handle
The manual exhaust air flap handle is available for the controlled removal of gases and hot exhaust air. With the exhaust air flap handle and a generously designed exhaust air opening in the furnace ceiling, the escape of hot exhaust air can be controlled manually. Ventilation or cooling can be adapted very precisely to the required process using the slide mechanism. In some models, the exhaust air flap handles can optionally be equipped with a servomotor and can thus be controlled automatically via the furnace control.
Safety – Safety switch
The safety switch, which is installed on the door of the furnace, interrupts the circuit to the heating elements when the door is opened and thus prevents live components from being touched.
Safety - Over-temperature protection
The integrated overtemperature protection prevents damage to electrical components. The electronic over-temperature protection is a safety routine in the control system, which can avoid a malfunction of the furnace and thus prevent damage to the electrical system.
Easy-to-maintain switchgear mounted at the back of the furnace
The switchgear is mounted at the back of the furnace and can be easily maintained and accessed.
Unique system prevents particles from falling onto the products
ROHDE uses a unique concept of mortar-free lightweight firebricks combined with R-SiC ceiling supports preventing cracks and particles from falling onto the products.
Efficient 3-layer insulation structure
The clever 3-layer insulation concept means the required temperature can be achieved with low energy input. A high level of energy efficiency is achieved even in continuous use.
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.
Heating elements securely recessed into bricks
Heating elements are recessed in a protected position into bricks and achieve high energy input and provide ideal protection against mechanical damage.
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.
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.
High-quality heating elements
We only use high-quality Kanthal A1 wire for the heating elements. In addition to a solid calculation with sufficient power reserves, careful processing in the manufacture of the heating elements is crucial for long service life. This leads to reliable and highly efficient heating elements as well as low spare part costs.
Plug-in control system
All ROHDE furnaces are connected to the control system via a standardised plug connection (CPC 14 or CPC 19). This enables quick and easy installation and simplifies the replacement of the control system during servicing.
3-year warranty
We produce each kiln by hand and keep to strict quality guidelines. Therefore, we offer a voluntary 36-months warranty to extend legal warranty regulations.
