Did you know that infrared emitters help embellish garden shovels?


Planting roses or digging over the vegetable patch - tools are necessary for any kind of work around the garden or house. Colored shovel blades are not just nice to look at, the applied coating additionally helps protect the blade against rust and corrosion.

The powder coating on the metal blades of the shovel, as well as the coating of machine parts, rims or engine housings, can be cured with infrared heat.

Gardening tools are exposed to plenty of nature's features - they have to withstand dirt and now and then the occasional downpour.
However, rain is not the only hazard: sunlight makes the colors on your gardening tools fade.

This is why it is of upmost importance for you gardening tools, e.g. a shovel, to be produced and coated at high quality. It is necessary that the coating remains on the product for two reasons: A well-coated garden shovel is aesthetically more pleasing than one with its coating chipping off. Furthermore, the coating helps protect the shovel.

A high quality and efficient coating of metals can be achieved with infrared emitters from Heraeus Noblelight.

Infrared heat - basics

Infrared heat transfers energy and generates heat where it is needed. PLC controlled infrared ovens are precisely designed to match the thermal process application. This saves energy, improves process stability and increases capacity and quality. The emitted radiation is in the range of 3,5 to 5,5 µm and thus exactly matches the absorption spectrum of powder coatings and water.

Gas catalytic infrared - efficient and reliable heating processes

Gas catalytic IR heat is idead for several processes, for example the coating of heat-sensitive substrates such as MDF, powder coating of metallic and non-metallic substrates, drying processes and thermoforming of plastics. The coating of the shovel blade is cured with a gas catalytic infrared system, thus making sure that the shovel does not oxidize and that the colors do not fade or chip off.

Gas catalytic infrared emitters convert natural gas or propane into medium to long wave infrared by using a special platinum catalyst. This flameless reaction differentiates the gas catalytic infrared system from other conventional infrared systems where gas is burnt in the process.

The heaters are available in ten standard sizes that can be combined to create large or small oven systems depending on the application. Each system can be split into any number of individual PLC controlled zones for precise process control.
