Chamber Furnace KE 330/10 EW
- Volume 330 litres
- Int. dimensions (w x d x h) 590 x 720 x 700 mm
- Power 22 kW
The KE 330/10 Dewaxing Chamber Furnace from the KE-EW series has a volume of 330 litres and is suitable for temperatures up to 1000°C.
The series has been designed to burn-out wax and plastic moulded parts using controlled exchange of air. It combines all relevant functions in one furnace: melting, clean combustion of the moulding material and the firing of moulds.
Furnaces from KE 150/10 EW upwards use the precise supply of pre-heated air to ensure even drying and heating of casting moulds thus reducing the risk of cracking of the mould. Good heat distribution throughout the dewaxing process shortens the firing process and allows efficient energy supply.
Exact control of the dewaxing process step prevents moulding material from uncontrolled ignition and at the same time allows reliable escape of exhaust gases. A special supporting grid is combined with a practical collecting drawer positioned below the furnace allowing the moulding material to be easily collected and emptied.

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.
Corrosion protection due to stainless steel in-frame ventilation
The fully in-frame ventilated steel construction contributes to low external temperatures and combined with stainless steel components provides effective protection against corrosion.
Durable textured paint finish
The high-quality light-grey RAL 7035 textured coating protects the furnace body and steel construction.
Robust swing door allows for safe opening
The convenient operation of the swing door allows easy opening of the furnace. The solid door handle ensures smooth operating procedures even when opening the hot furnace while the process is running.
Flexible door sealing allows for thorough door closing
A flexible insulating cord ensures a seal between the door and the furnace opening. Minor unevenness can be corrected and the door can be closed flush with the furnace.
Lockable door catch
The robust door catch guarantees safe closing and locking of the door.
Stainless steel door frame protects against the effects of heat
The door frame is reinforced with stainless steel sheets and protects the construction against the effects of heat.
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.
Unique system prevents particles falling onto the products
ROHDE uses a unique concept of mortar-free lightweight firebricks combined with R-SiC ceiling supports preventing cracks and particles falling onto the products.
Easy-to-maintain switchgear mounted in a Rittal switch cabinet
The switchgear is mounted in a Rittal switch cabinet 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 solid-state relays for control
The furnace is controlled by low-wear, silent solid-state relays with external cooling elements.
4-side heating allows for good heat distribution
Heating from 4 sides (side walls, back wall and door) 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.
