Contec Oil Mist Separators Ensures the Façade Design of ETFE Cushions for Efficient and Environmentally Friendly Glare, Heat, and UV-Protection

Contec oil / mist seperator

The use of the Contec oil mist separator (COMS) in the field of building construction has once again proven its advantages in environmental aspects.

The filtration challenge

The Media-TIC building in Barcelona (Spain), designed by Cloud 9/Enric Ruiz Geli impressed with its glass façade, which rests on a steel structure. However, buildings with reinforced glass insert make high demands on the glare, heat, and UV-protection.

UV-protection has been integrated in the south-west façade of the building. On this side the building is completely covered with ETFE-film (ethylene-tetrafluoroethylene).

The membrane uses ETFE cushions made of two layers filled with nitrogen, which act as a solar filter. Solar sun shading is achieved on the roof installed system of inflation unit, oil mist separator, and fog generator, which injects fog into the cushions.

Through the pneumatic displacement of the center to the outer or inner foil film, UV transmission can be controlled. This system provides variable shading, which reduces solar heat gain up to 90%.

The solution

This application sucks oil mist separator type 180/435 of the Contec aerosol mist, which is pumped into the nitrogen-filled air cushion again.

Oil-based fog fluid is used, which neither dissolves nor decomposed over a long time. At high-concentrations, there is a risk of explosion, slipping, and blowing out into the atmosphere cannot be unfiltered. For these reasons, a separation of oil mist by the oil mist separator from Contec is necessary.

The advantages

Contec oil mist separator (COMS) is equipped with a side channel blower that generates adjustable negative pressure in the system.
This leakage and the leakage of oil mists are prevented.

Due to the long service life of the filter elements and the automatic return the system requires minimal maintenance. Oil droplets contained in the air are trapped in the two-layer Contec glass fiber filter elements with integrated reinforcing fabric, flow through the depth of the filter and are collected as larger drops in the filter element. The air flow pushes the drops towards the downstream surface of the filter element.

The oil separated by the filter element drops down from the outer surface onto the surface below. Here it is collected in the ring space surrounding the intermediate bottom and passes through the drain.

The purified oil is returned to the oil reservoir through the oil return line. The solid particles contained in the exhaust air are also retained by the filter.

Contec oil mist separators are installed on the lubrication oil tanks of turbines, compressors, large-scale compressors, turbo-engines, and other equipment with oil systems.

Contec oil mist separators filtered exhaust is clean and dry. The recovered oil is supplied to the oil circuit and as eco-friendly, as well as cost recycled. A Contec oil mist separator (COMS) was awarded the Environmental Technology Award 1990.
