Frequently asked questions

What are the benefits of electric heating?

Electric heating is virtually maintenance-free. Apart from some periodic checks or inspections, no preventive maintenance is required. The production process does not have to be stopped to do so. In addition, electric heating systems are relatively easy to install and connect and easy and precise to control.

What is the maximum temperature which you can reach with electric heaters?

You can achieve high process temperatures by means of electric heating. Most forms of electric heating can reach temperatures of up to 300°C, but there are also heaters that can even be used up to 1000°C.

Can you use heating elements in all kinds of applications?

No, that is not wise. Electric heating elements are often especially made for a specific application (for example for water, air or oil). Although they look very similar, the structure is certainly different: the material partly depends on the product that has to be heated and the heat input, absorption and load is different for each medium.

How do you control electric heating elements?

Heating elements are often controlled externally by means of an external thermostat or control box. This can be done, for example, with a digital control system or by means of a capillary thermostat.

Where are electric heating systems being used?

Electric heating systems are often used for frost protection, process heating and space heating. These applications are found in almost every sector, especially in the food industry, oil and gas sector, tank and machine construction, cooling industry, utility and residential construction.

What is the lifespan of electric ramp heating?

Ramp heating can easily last more than 20 years. It is important that the system is properly installed and tested during installation. Once the cables are in the concrete, little can go wrong.

Does electric ramp heating need to be maintained periodically?

Electric ramp heating is virtually maintenance-free. It is advisable to have an annual inspection before the winter period, which includes a visual inspection and the measurement of components. We offer service contracts for these inspections.

Which top layer is used on ramp heating?

Electric ramp heating can be placed under various top layers. Concrete is the most common (cables on the top net with a 3-4cm coating), clinkers (cables under a 2-3cm sand bed with about 6cm clinkers on top) and asphalt.

What power per square meter should you install with ramp heating?

The power that is installed depends on the type of finishing layer and its thickness. For concrete this is generally 200-220w / m2, for clinker finishes approx. 300w / m2 and for asphalt 300 / 350w / m2.

What parameters does electric ramp heating control on?

Ramp heating controls on a combination of low temperature and winter precipitation.

What types of heating cables are there?

Self-limiting heating cables, constant power heating cables and serial heating cables.
