Filter houses on offshore platforms cope with moisture and sandstorms

Oil fields located in the Arabian Gulf needed new filter houses for their platforms to ensure a reliable operation of the gas turbines‘ compressor sections. The local conditions are harsh with moisture, salt and sand. Thus, engineering and construction of filter houses had to consider optimal protection against corrosion. A 3-stage filtration system with hydroMaxx coalescers provides high efficiency and allows continuous operation.

Marine air intake filter units protect gas compressors for offshore platform

The Brazil-based gas field runs gas turbines for the compression of gases from the nearby offshore platforms. The marine air intake units made from stainless steel prevent turbine blades from corrosion or erosion. Weather louvres, mist eliminators and a filtration system with water barrier protect against harsh weather conditions with salt and fog.

Viledon IceProtect - the infrared anti-icing unit

Easy handling and maximum protection

Viledon IceProtect is a unique, variable infrared anti-icing unit, which is used as icing protection for filter walls. At the heart of IceProtect is the infrared heating element. This is mounted within a stainless steel housing and protected against dust and splashing water by a built-in quartz glass protective tube. A grille provides additional security.

IceProtect is extremely easy to handle and the unit can easily be mounted on the filter house. The infrared heater is maintenance free and can be simply removed if required. A dirty protective tube can be quickly cleaned, ensuring maximum heating performance at all times.

Your advantage with Viledon IceProtect

  • Cost-effective alternative to systems using hot bleed air from turbomachinery compressors or heat exchangers 
  • No additional pressure drop 
  • Module can be supplied in different lengths 
  • Delivery includes complete measuring and regulating technology, including switch cabinet 
  • Protection of heating element against dust and water spray to IP54 standard 
  • Easy change of heating element
