HEATING chambers FOR PAINTING AND DRYING  

Why Rimor?

Radiant panels systems are successfuly used for water-based and solvent-based paint drying with
low operating costs ensuring an efficient and safe alternative to the radiant electric panels.

They can be applied with surface frame or in closed chambers in order to allow a better drying quality in the hidden parts.

The system guarantees an efficient drying even on big dimension components. It is particularly appreciated the push/pull ventilation system of the radiant panels that allows the panel’s ventilation with a centrised system with supply and exhaust air.

THE PRODUCT

Rimor heating system is a gas catalytic heating and cooling system with a “push or push/pull” technology. It is made up of 3 modules, an upper one, and two lateral. As shown in figure, the machine has been purposely designed for being used in the automotive sector, in details, for the paint drying of cars body.
The lateral modules have been designed and made so that they can longitudinally and transversally slide, to fit any different car size and inclination. They can thus be placed perpendicularly
to the surface.
The heat source consists of catalytic burners, conveying heat mainly by radiation through a flameless combustion of natural gas. The flames lightning is avoided by combining the low temperatures of the panel with the catalyst action, even if solvents are present. The catalytic burner emits infrared radiation, absorbed by the surrounding objects. The energy emitted by the catalyst surface moves along straight lines.

Everything Aboard

Air handling:

Dual systems PUSH or PUSH-PULL, the Air Radiant Heating System can direct the airflow onto the panels. The air distribution from the upper module to the lateral ones occurs through flexible hoses, modelled according to airflow.

Air system:

It is dimensioned according to the required flow rate.

The air cools the backside of the catalytic panels, in addition, it contributes to homogeneously dry the surface.

The airflow can be changed by means of regulating valves.

The internal air distribution to the modules is optimized through sheet-metal bulkheads, which convey the air towards the surface irradiated by the panels.

Gas system:

It’s made up of ¾ steel pipes in a ring-shaped arrangement, in order to obtain a correct exercise pressure of the combustible gas (methane or GPL).

The distribution of gas from the upper module towards the lateral ones is carried
out by means of ¾ flexible steel pipes with nipple joints to allow a faster assembly.

Electric system:

Electric plant: the preheating resistors cables of burners and the type K thermocouple cables for internal temperature control are conveyed through an internal duct being inserted in a derivative box.

The box is placed in a comfortable position, so as to facilitate the connection as much as possible.

HOW THE COMBUSTION PROCESS TAKES PLACE

 

  • The gas enters the combustion chamber (F) through a nozzle placed on the backside of the burner.
  • A support grid (G) ensures a uniform combustion chamber.
  • The gas passes through an insulating panel (E) with established density. The panel prevents the heat transfer to the backside of the burner and facilitates the gas diffusion by serving as flow barrier.
  • The gas flows through the catalytic panel (G), preheated by an electrical resistance (G) powered by 230V AC. The terminal sections of the resistance are shielded by a certified box (I). The flash burner is furthermore equipped with a type K thermocouple (K) for the internal
    temperature control.
  • Oxidation occurs when the gas, after it gets into the catalytic panel, touches the catalyser.
    The catalytic panel is protected by a fiberglass net, resistant to high temperatures, and by a stainless steel grill (B), fastened to its edges by a stainless frame.
  • The burner radiating surface is furthermore protected by a chrome-plated grid (A), ensuring a safe distance from the surrounding objects.

Various configurations available

Combination of catalytic technology and convection technology

Rimor ventilation technology can provide a controlled wind on the surface. In addition, it allows to recover the exhaust gases of the process.

The ventilated solution by Rimor & combines the quality and strength of the catalytic panels by with the ventilation technology studied by Rimor.

This combination optimizes the heating process and gets the best from catalytic panels, ensuring their integrity and sucking the powders created throughout the process and throughout the panel lifetime.
