Farcical codes!

A report on www.reven.de concerning currently applicable exposure limits relating to air pollution and air cleaners.

rules

The fine dust pollution in the outside air has been a matter of discussion for several years now. Vehicle and industry emissions are in the focus of attention; the pollution of indoor air at workplaces is obviously neglected. The related discussions and regulations are becoming more and more grotesque: The Federal Emission Protection Act (BImSchV) stipulates limiting values for the outside air, which remain dramatically below the permissible WELs for indoor air. Obviously, nobody has noticed that until now. It is high time to point out this absurdity.

New energy efficiency directive

REVEN® air cleaner now also available in an energy-efficient eco-design!

erp

By adopting the Kyoto Protocol, the European Union has undertaken to reduce CO2 emissions by at least 20 percent until 2020. To achieve this climate goal, the EU adopted the ErP Directive (Energy-related Products Directive).  This new directive helps with studying the savings potential of numerous energy-related products and stipulating minimum requirements. Limits for fans were defined in June 2010 and are valid now.

Electrostatic separator

Food processing and mechanical manufacturing free from emissions.

rke_newIn an urban environment, metal processing factories, restaurants and other food processing companies may have a problem with complaints about odour nuisance and oily and greasy exhaust air. A high-grade oil mist separator on an electrostatic basis can alleviate the situation. Properly dimensioned equipment suitable for integration into the exhaust duct can remove finest aerosols and odorous matter.

New REVEN® X-CYCLONE® Profile available in 2011

The 5th generation of the REVEN X-CYCLONE® profile – a new arrow profile for a healthy environment and improved working conditions!

729ba392fb

The X-CYCLONE® filters manufactured by Rentschler REVEN GmbH are the fruit of persistent research throughout the previous decades. The X-CYCLONE® filters consist of rectangular elements with a thickness of 50 mm. They have proven their worth millions of times as air cleaning equipment in the mechanical sector and in the food industry. The X-CYCLONE® filter elements distinguish themselves considerably from traditional aluminium mesh or metal sheet filters because their development has been based on a scientific flow analysis and sound particle measurements and analyses. Only because of these research efforts, we were able to continuously optimise the separating performance of our X-CYCLONE® filters and will launch the fifth product generation in 2011 – the new REVEN® X-CYCLONE® Arrow Profile.

REVEX Air Cleaner now available!

The REVEX® spraying system is suitable for dry cast-iron machining and other machining processes involving a high release of vapour and smoke .

UC_COMPACT_REVEX

The REVEX® spraying system is suitable for dry cast-iron machining and other machining processes involving high vapour and smoke release. In many cases, you can dispense with the particulate air filter. The spraying system is suitable for connection to the tool cooling cycle of the processing machine (alternatively: supply via a separate tank and a pump by the customer). The system sprays cooling lubricant onto the oil and emulsion mists extracted from the processing machine via REVEX® nozzles that are installed in the Ultra Cleaner. For technical data sheets in English, Chinese, French, Spanish or Japanese, please contact us via info@reven.de.

REVEN X-CYCLONE & DIN18869

The X-CYCLONE® separator made by Rentschler REVEN is the first device worldwide that passes successfully the flame-resistance test in accordance with the new DIN 18869.

REVEN – The X-CYCLONE® separator made by Rentschler REVEN is the first device worldwide that passes successfully the flame-resistance test in accordance with the new DIN 18869. In Part 5, the standard describes a method for testing the flame-arresting capability comparable to that specified by UL 1046, with a flame intensity that is up to three times higher, however! The X-CYCLONE® separator is the only separator of airborne liquid particles available on the market that was tested in accordance with UL 1046 and DIN 18869. It is the only device to be classified as a class A/DIN18869 separator.

German army hospital in Ulm

One of the greatest state-of-the-art extraction ceilings will be commissioned these days in the military hospital in Ulm.

ulm3ulm2Ulm in December – One of the greatest state-of-the-art extraction ceilings will be commissioned these days in the military hospital in Ulm. The extraction ceiling uses a modern air-induction system. The airflow is optimised and induction airflows direct the exhaust air to the filters. The filters of the extraction ceiling clean themselves fully automatically and need not be removed for this purpose. The ceiling is made of stainless steel and powder-coated aluminium.  Please take a look at the following illustrations.

New fire test for filters

This year, the new DIN 18869 standard came into force. It describes a testing procedure of the behaviour of aerosol separators (filters) under fire and their suitability to arrest flames. The testing is similar to the method described in the UL 1046 standard with a flame intensity that is approximately twice as high, however!

fire_testThis year, the new DIN 18869 standard came into force. It describes a testing procedure of the behaviour of aerosol separators (filters) under fire and their suitability to arrest flames. The testing is similar to the method described in the UL 1046 standard with a flame intensity that is approximately twice as high, however! Unfortunately, no test stand satisfying the requirements of the new standard has been available until recently. Therefore, Rentschler REVEN started to build an new compliant test stand in close cooperation with test institutes and suppliers under the supervision of the REVEN project manager Marcus Auer. The test stand will be completed by the end of this month and by the end of the year, we will be able to test our equipment in accordance with DIN 18869 on the new stand. The following illustration shows the DIN18869 test stand.

REVEN MINIs for DMG turning machines

REVEN MINI, a fully integrated air cleaner for lathes of the DMG CTV160/250 type.

dmg_machineBecause Rentschler REVEN coordinated the design of its air cleaner with the manufacturer of the machine tool GILDEMEISTER in the early project stage, the company succeeded in developing an ultra compact air cleaner that is fully integrated into the machine tool! The new vertical GILDEMEISTER® lathe type CTV160/250, shown in the illustration below, comes in series with a REVEN MINI air cleaner.  The air cleaner is integrated in the machine housing and does its work underneath the lining.
