Der Entwachs-Kammerofen KE 20/10 mit einem Volumen von 20 Litern ist ein Brennofen aus der Serie KE-EW für Temperaturen bis 1000°C.

Die Baureihe zum Ausbrennen von Wachs- und Kunststoff-Formteilen mit gesteuertem Luftwechsel vereint alle relevanten Funktionen in einem Ofen: das Ausschmelzen, das rückstandfreies Verbrennen von Formstoffen sowie das Fertigbrennen der Gießformen.

Ab dem KE 150/10 EW wird durch die präzise gesteuerte Zufuhr von vorgewärmter Luft ein gleichmäßiges Trocknen und Erwärmen der Gießformen sichergestellt und damit die Rissgefahr am Formkörpern verringert. Eine gute Wärmeverteilung während des Wachsausschmelzens ermöglicht ein Verkürzen des Brennprozesses sowie einen effizienten Energieeintrag.

Die exakte Regelung im Prozessabschnitt des Entwachsens verhindert ein unkontrolliertes Entzünden von Formstoffen, gleichzeitig werden die entstehenden Abgase sicher abtransportiert. Der spezielle Auflagerost – ausgeführt als Entnahmepalette – in Kombination mit der praktischen Auffangwanne unter dem Ofen, erlaubt ein leichtes Sammeln und Entleeren des Formstoffes.

Torsion-resistant riveted steel housing

The housing consists of a torsion-resistant rivet 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.

Adjustable feet can be set easily

Adjustable machine feet allow for precise height adjustment and guarantee a secure footing.

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.

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.

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.

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 at the back of the furnace

The switchgear is mounted at the back of the furnace and can be easily maintained and accessed.

Integrated safety due to safety 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.

3-side heating allows for good heat distribution

All-around heating (on the side walls) combined with floor heating 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 “Schuko” connector allows for easy connection

The standardised Schuko 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.
