Drinking water

Gases help to produce drinking water of perfect quality. Nowadays, modern treatment facilities largely avoid the use of poisonous or corrosive chemicals. Instead two industrial gases are increasingly used: oxygen and carbon dioxide, both a natural component of the water cycle.

The VPSA Oxygen generator production line consists of the main technological equipment:

1. Air is drawn in and filtered. 2. O2 - Oxygen can flow through Containers switch between adsoption 2. N2 - Nitrogen stick to porous substance (absorbent)... and regeneration every 10 seconds 3. O2 - ...and is conducted into the buffer storage tank. 3. N2 -....and is drawn off by the vacuum pump during regeneration 4. N2 - ... and discharged. 4. O2 - Oxygen with a purity of 90 to 94 % goes directly to production. Adsorption - selective adhesion of gas molecules to a porous substance Regeneration - removal of the adsorbed gas molecules throught a reduction in pressure

Aluminum melting process

Just over 50% of aluminum products are produced from recycled secondary aluminum, with the main process steps being scrap conditioning, melting and casting. Depending on the contamination and bulk of the scrap, various types of furnace are used during melting: rotary drum furnaces, chamber furnaces or shaft furnaces. To remove impurities, the aluminum melt is cleaned by gas purging. This takes place in holding furnaces or specially designed ladle stations. In the case of the melt being transported in ladles on vehicles to another processing location, it is necessary to preheat the ladles with burners.

bakery products

The product variety of baked goods ranges from rolls to cake variations. Messer's application technology know-how in this segment is just as extensive. This starts with silo inerting during raw material storage, continues with cooling processes during kneading and extends to the transport of chilled or frozen baked goods.
