Electric heating of wind turbines

In 2020, the Netherlands placed the most wind turbines of all European countries, which was good for a 1979 Megawatt power. Up to 2030, 10 offshore wind turbine parks will be added. In all these windmills, heating is required in various places to ensure optimum operation.

Warm rotor blades during maintenance

To ensure proper overhaul and maintenance, we can provide a special system that keeps the rotor blades warm during the maintenance period. The PHBC-6 system consists of a portable controller (tablet-style) combined with heating jackets with built-in temperature sensors.

The controller also measures and records ambient temperature and humidity. This system offers several advantages:

  • The blades are always at the correct temperature during maintenance
  • The correct TG value is achieved immediately each time
  • No more errors in recording and monitoring the values
  • Less downtime due to perfect repair and maintenance
  • Possibility to start multiple repairs per day per turbine
  • Automatically generated and fully documented reports for the customer
  • Time savings in most parts of maintenance/repair

The production and delivery of these heating blankets are bespoke because each application is different and the material of the rotor blades plays a role. Our consultants calculate the power density needed to achieve a perfect TG value every time. Due to the light material and flexibility, the heat blankets are easy to use.

Robust fan heater for wind turbines

In wind turbines, fan heaters are used in different locations. Due to the rough conditions that can arise from the weather and the high altitude, these fan heaters must meet various requirements.

Especially for wind turbines, Heating Group International provides fan heaters that operate at temperatures down to -40ºC and are also suitable for high altitude applications. We supply these fan heaters in various versions with different voltages and wattages. This depends entirely on the application. The heaters are CE or UL/CSA certified.

Frost protection/ice-free rotor blades

With the specially developed units for frost protection and de-icing, freezing of rotor blades is prevented in cold climates. This prevents downtime. Whether the wind turbine is switched on or off, this unit can be used continuously if desired.

Immersion elements for wind turbines

Both in the gearbox and the hydraulic unit, immersion elements are used for heating and maintenance of oil and lubrication systems. Heating Group provides immersion elements that meet all requirements and specifications for use in wind turbines. There are different voltages, wattages and lengths possible and there is a choice between flange or wire. A big advantage of these immersion elements is that they are very quick to install and that the oil does not need to be drained.

Flow heaters for wind turbines

The built-in pump of these flow heaters circulates the lube oil through the gearbox. The flow heater is equipped with a pump, temperature limiter, and Pt100 sensor. In addition, we can also supply glycol heaters for pre-heating cooling water in the cooling/heating system in inverters of wind turbines before start-up.

Heating for control systems in wind turbines

Temperature differences create condensation even in sealed enclosures. In combination with dust and aggressive gases, condensation causes corrosion, resulting in stray current and arcing. In addition, too high or too low temperatures can cause parts to fail. This provides a high-security risk and causes huge costs due to downtime. Heating Group provides cabinet heating that prevents condensation. This ensures optimum protection of the control panel.

Silicone heating mats for wind turbines

The lightweight, thin silicone heating mats have a low thermal mass and fast warm-up time. Silicone mats have even more advantages:

  • They are custom made.
  • Easy to install
  • No maintenance required
  • Flexible

Silicone heating mats are used for heating battery trays, pipelines and lighting systems.
