Drägerwerk AG is a German company based in Lübeck[7] which makes breathing and protection equipment, gas detection and analysis systems, and noninvasive patient monitoring technologies.[2] Customers include hospitals, fire departments and diving companies.

History

The company was founded in Lübeck in 1889 as Dräger & Gerling by {{Interlanguage link multi|Johann Heinrich Dräger|de|3=Johann Heinrich Dräger|lt=J. Heinrich Dräger}} and Carl Adolf Gerling.[3] The first patent was taken out for a reduction device for using carbon dioxide to dispense beer. In 1902 Heinrich Dräger's son Bernhard entered the management; from then on, the company was named Drägerwerk Heinr. und Bernh. Dräger. Since 1970, Drägerwerk has been a public limited company, or Aktiengesellschaft (AG) in German.

In 2003, the aerospace division was sold to Cobham plc. In July 2006, it was announced that Draeger Aerospace GmbH had been acquired by B/E Aerospace, Inc.[4]

Draeger's stock has tumbled to its lowest YTD close of 66.6 EU on of 4/18/18. Its YTD high was 104.15 EU on 5/10/17.

Dräger Safety GmbH

Dräger Safety GmbH is a manufacturer of personal protection and gas detection technology, and a supplier of safety systems for industry, fire prevention, mining and other hazardous areas.[6] The products and services from Dräger Safety warn and protect people from airborne pollutants and enable people to breathe reliably even in extreme situations.

Dräger claims to have longstanding experience, especially in the fields of gas management, gas flow control, gas monitoring and gas measurement.

The current product range encompasses respiratory protective equipment for firefighters, miners and other industrial personnel as well as complete air filter and air supply systems, portable and fixed gas detection and warning systems, devices for on-site or laboratory contaminant analysis, and instruments to determine a person's breath-alcohol concentration.

Dräger combines the practical use of equipment with, for example, consultancy services, training, maintenance, service and commissioning. Represented in over 100 countries, the company has 40 subsidiaries and, with its 3,600 employees, achieved global sales of €557.8 million in 2005 (EBIT: €40.7 million).{{Citation needed|date=February 2008}}

Dräger Safety operates production plants in Germany, Great Britain, USA, Sweden, South Africa and China.

Dräger Safety faces heavy competition from other manufacturers of safety equipment such as Sensidyne, LP. Also, the company’s competitors include Mine Safety Appliances, Industrial Scientific Corporation and RAE Systems.[7]

Dräger supports the German Firefighting Sports Federation in the German firefighting fitness badge.[8]

Colorimetric gas detector tubes

Dräger was one of a few companies who were early pioneers of colorimetric gas detector tubes (also known as detector tubes) used to measure the concentration of gases present. In a typical colorimetric gas detector tube a known volume of air is pumped through a tube using a pump. The tube typically has a layer which indicates the analyte by changing colour, depending on the amount of the gas which has passed through the tube the length of the zone which has changed colour will be different.[9][10] Today colorimetric gas detector tubes are used throughout industry as a low-cost and easy-to-use tool for detecting the presence of gases and are available from a wide range of manufacturers.

An early limitation of detector tubes is that they were designed to detect a single known gas or vapor. Advancements in the design and capability of detector tubes came with the introduction of such tools as the HazMat kit. The specialty kits are designed for use by hazardous material response teams in determining what gases or vapors are present through using a "stack" of colorimetric material that change color based upon the presence of an organic or inorganic gas.

Alcohol Screening Kits

Dräger developed their first Alcohol screening kit in 1953 when some employees came into work hungover following a party the night before. It was originally developed using silicon crystals, where a breath sample was passed through these silicon crystals, if there was alcohol in this breath sample, a chemical reaction would occur resulting in the crystals changing colour. This particular method is still used today to create "single use breathalyzers."

Dräger's first digital display Alcohol Screening Kit was developed in 1980. Later they developed a breathalyzer that uses a fuel sensor. Many of Drägers breathalyzers have home office approval, which means they can be used by the police in a variety of countries, including the UK.

Diving equipment

In 1912 the Drägerwerk had developed a standard diving dress without an umbilical. Its air supply came from a rebreather.

Since 1941 Hans Hass used bag-on-back rebreathers originally built by Dräger for self-rescue of submarine crews (Tauchretter, like the Davis Escape Set). The first Dräger-Tauchretter had been built in 1907. In 1926 the Bade-Tauchretter was brought into action for rescuing drowning swimmers.[11]

It makes the popular Atlantis, Ray and Dolphin line of sport diving semi-closed-circuit nitrox rebreathers. It also makes the LAR-5 and LAR-6 military oxygen rebreathers, and LAV-7 military rebreather (switchable between closed-circuit and semi-closed-circuit).[12][13]
