Heating Metal Structures Before Painting with Infrared Heaters

At the Zhytomyr Armored Plant, Teplov was faced with a specific technological requirement: heating the surface of metal structures before painting.

The structures were located inside a large production workshop and could be positioned in different areas. The solution therefore had to be movable and capable of being positioned close to the object being processed.

For this purpose, Teplov P4000 industrial infrared heaters were installed on a mobile structure.

For a different task — industrial heating of workshops and production facilities — the heating system is designed around the building and its overall thermal requirements.

The Technological Requirement

The metal structures had to be heated directly in the working area before painting.

The large size of the workshop and the changing location of the structures were important factors. The objects being processed could be located at different points within the facility.

The equipment therefore had to work with the surface of a particular metal structure rather than with the entire workshop volume.

This determined the localized nature of the solution.

Infrared Heating of the Metal Surface

Infrared radiation can be used to transfer heat to the surface of an object toward which the radiation is directed.

That principle was central to this project: the objective was to heat the metal structure before painting, rather than establish the same thermal conditions throughout the workshop.

A Teplov P4000 industrial infrared heater was used as the heat source for the localized heating zone.

Mobile Heating Structure

The heaters were installed on a specially designed mobile structure.

Its purpose was to allow the infrared heat source to be moved toward the required metal structure.

This arrangement matched the conditions of the facility, where:

• metal structures could be located in different areas;
• the working position could change;
• heating was required before a specific technological operation;
• the entire workshop did not need to be treated as one heating zone.

The mobile structure therefore provided the required positioning of the equipment relative to the heated object.

Why Localized Heating Was Required

In conventional production-facility heating, the thermal system is designed around the working space as a whole.

In this project, the actual heating target was a metal structure.

The key requirement was therefore the ability to direct the thermal effect toward the required surface. This illustrates another industrial application of infrared equipment: not only space heating, but also localized heating for specific technological processes.

The project is therefore specifically associated with localized heating of metal structures before painting.

Equipment

The project used Teplov P4000 industrial infrared heaters.

Project Data

Infrared Heating for Technological Processes

This project demonstrates an application in which the point of heat delivery is a specific metal object rather than the entire building.

For industrial facilities where individual metal structures need to be heated before painting or another technological operation, the equipment positioning and the required heating zone become part of the engineering solution.

Other installation and application options are available in the ceiling infrared heaters section.
