This pre owned RDM ‘MODULAIR’ Electric Oven is of the hot air recirculation type.

With this design, the Oven interior is heated by a fan assisted convection process. The heated air is constantly recycled around the Oven’s interior to maintain superb temperature consistency.

RDM Oven systems offer simple and very accurate digital temperature control. The ovens are exceptionally energy efficient and responsive due largely to the utilisation of the latest control technology as well as the oven‘s fully integrated, insulated construction.

RDM Ovens incorporate electronic over temperature protection, electronic fan sensors, a powered fume exhaust system, an internal safety handle to prevent operator entrapment, and a disintegration type Explosion relief system.


The RDM Oven is intended for use within the Humidification, Industrial Vacuum forming, Composite curing,  Drying, Paint stoving, Rubber Curing and General Heating applications from 30 to 250 Centigrade. 

These include:

  • Humidification 
  • Vacuum forming 
  • Composite curing
  • Moisture drying
  • Paint Stoving
  • Epoxy/Polyester Powder Curing
  • Lacquer Drying
  • Hydrosetting
  • Battery processing
  • Moisture removal
  • Plastic Curing
  • Rubber softening
  • Spring stress relieving


The Oven is complete with heavy duty insulated and reinforced swing doors The body is manufactured of double skin Galvanised steel panels, with high grade rockwool Insulation.

The explosion relief system is incorporated in the oven roof area and comprises of special panel work which is specifically designed to disintegrate and vent off to atmosphere should an explosion occur within the oven. The Oven is further quipped with an internal safety door handle to prevent any operator entrapment.

To ensure good performance, the RDM oven incorporates a medium pressure multi-vane centrifugal fan complete with scroll casing to provide a positive and well controlled air movement. The electric heating elements are positioned in the returning air to enable an even heat distribution and large duct work ensures that the returning high air volume will not disturb the product due to turbulence.


Fitted to the side of the oven is a PLC controlled JD Ultrasonics control panel which has the ability to inject air and atomised water to either control the humidity, or dampen down the atmosphere to reduce nuisance dust levels within the process chamber.


Humidification is the artificial regulation of humidity in environments. When the atmosphere becomes too dry, moisture is drawn from surrounding materials within the environment.

The humidification system is ideal for maintaining or increasing the level of relative humidity by introducing moisture back into the air without causing wet areas or excessive water drop out.

Dust control

Dust Control System is an important factor in meeting both environmental and health and safety requirements, helping and protecting employees and reducing emissions.

The dry fog dust suppression system controls both breathable and fugitive airborne dust without wetting the product and equipment while adding very little moisture.

To ensure a safe start up and shut down sequence, the Oven includes an electronic sequence control system. This system ensures that the heater will only switch on once the fans have safely evacuated any solvent fumes that may have ammassed in the oven chamber.

At the end of a shift, a simple press of the button initiates the controlled shut down cooling sequence, allowing the fans to cool the heaters properly prior to shutting down fully.
