Packing industry

To ensure the rigorous air demand in the food industry as well as medical engineering in compliance with the strictest explosion protection regulations, EVG supplies high-performance ATEX fans with a state-of-the-art design and best energy efficiency. The fans are welded gas-tight and leak tightness is guaranteed by constant monitoring in production. A multi-labyrinth seal with return rounds off the scope of supply and guarantees 100 % tightness, even in the case of the most demanding continuous operation.

 

Machine construction - Exhaust air plant

A dust free environment is a basic requirement for a perfect surface. To make sure this is successful even under difficult conditions, EVG supplies radial fans with a belt drive, with high static pressure and high volume flows. The high efficiency of > 85 % and long-lasting design in stainless steel guarantee uninterrupted operation at low operating costs.

To ensure that the personally preferred colour remains brilliant for the entire life of the car, the paint job consists of many work stages and multiple layers. The spray cabin is therefore the core element of the paint shop. To remove the resulting paint mist from the air, EVG supplies the perfect exhaust air fans in an ATEX version. We use built-in fans with a freewheel for the incoming air. To clean the exhaust air after cathodic electrocoating (TAR), gas-tight housing fans are used. In this way, EVG fulfils the highest requirements of BMW for this particularly environmentally-friendly integrated painting process.

In painting plants, the drying process is used to harden the coats of paint. To create the perfect surface, the fans are designed exactly for the operating point. The absolute absence of silicon is a basic prerequisite. Our housing fans are used for the dryer exhaust air and our free-wheeling built-in fans are used for the incoming air.

Melamine resin is a colourless substance that cures abruptly at a specific temperature. EVG developed a pressure surge-protected special fan in stainless steel with a magnetic coupling to convey the substance. To prevent unwanted hardening inside the fan, the fan housing can be temperated for the specific process and thereby guarantee an ideal melamine production process.

With the 11 MAN diesel motors, type 18 V 48/60, operating the power station in Garabito, Costa Rica, the EVG hot gas fans produce a permanent vacuum during and after the operation of the 18,000 kW MAN motors to prevent the aggressive sulphurous exhaust gases at temperatures of up to 450 °C from flowing back into the motor. This prevents the inside of the motor from corroding in the tropical climate and extends the maintenance intervals and service life of the motors.

Tunnel Technology - Flystation Tokyo

Maximum efficiency and optimised design with probably the largest axial fan used for indoor skydiving, combined with a perfectly managed tunnel leads to the highest wind speed of up to 320 km/h (200 mph) in the flight chamber. This guarantees unlimited performance for skydiving beginners as well as for the most experienced professional flyer.

Original comment of our customer: ­­ ″Some cool figures to you. The axial fans working at 750rpm consume exactly 400kW as we expected. But the velocity at the flight chamber is around 360km/h at this speed :) Actually even most experienced sportsmen are afraid to fly at this speed. nobody still tried it "

In the sugar manufacturing process heat is generated in a range of 60-70 °C. This heat source is used in low temperature dryers (NTT) of Swiss Combi to pre-dry beet pulp. This can save natural gas to a great extent, which would otherwise be required for the drying of beet pulp. The required large amounts of air are circulated by 24 centrifugal fans in stainless steel. Therewith EVG accomplish a major contribution to CO2 reduction in the drying beet.

Drying animal feed is a complex process for which the customer requires maximum reliability and extremely high efficiency of the fans. In this case, EVG has developed three customised stainless steel process fans with an installed power of more than 700 kW and with an efficiency of up to 90 %. In this way, we help our customers ensure the very best quality during the drying process.

Before further processing to wood pellets sawdust must be sufficiently dried. The EVG centrifugal fans thus drag the warmed air in the heat exchangers through the product layer and the polyester tape of Swiss Combi belt dryer. The air becomes saturated with moisture from the biomass, which is sucked in by the fans and discharged through the chimneys to the environment. The high efficiency of EVG centrifugal fans support our customers effectively in the economic use of natural resources.
