The ELS 330/13 Chamber Furnace with the Ergo Load System has a volume of 330 litres and is a furnace from the ELS series suitable for temperatures up to 1300°C.
Based on the design of chamber furnaces, ROHDE has developed the unique ELS Ergo Load System furnace concept. The free-running mechanism of this furnace allows the floor to be pulled out completely.
The furnace floor can be pulled out effortlessly using the door that opens to 180° and allows charging on three sides. This makes it faster, safer and more efficient to load the furnace, combining the compact chamber furnace construction with all the advantages of truck furnace loading.
The entire steel construction is equipped with an in-frame ventilation made of stainless steel sheets contributing to low external temperatures and the best possible corrosion protection. The insulation comprises three layers and the furnace floor is fitted with a conical sealing cord providing optimum sealing.

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.
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.
The ELS Ergo Load System ensures easy loading
The ROHDE Ergo Load Systems allows the furnace floor to be pulled out completely with a smooth-running mechanism enabling convenient loading from three sides. Comfortable, ergonomic and safe.
Flexible and adjustable truck sealing
The truck is fitted with a conical insulating cord providing optimum sealing of the furnace floor and preventing incoming draughts.
Efficient 3-layer insulation structure
A sophisticated 3-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.
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.
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 mounted on support rods
Heating elements are mounted in protected position on Sillimantin support rods and achieve ideal heat radiation and facilitate easy replacement of heating elements.
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.
