This breathing air is free from effects of the working environment. ZANDER offers the marketfor the industrial breathing air sector proven adsorption technology, with a high emphasis on savety in regard to maximum allow-able impurity concentrations depending on specific coun- try regulations. Adsorption dryers of the BS-MT series are eminently suitable as breathing air conditioning units for indu- strial applications by virtue of exactly matched conditio- ning steps <0,5mg/m 20-23 %= 3 <5,0mg/m 21,5 %= 3 -Pre filter -Adsorption phase A -After filter -Cleaning 2nd stage -Catalyst stage -Cleaning 1st stage -Adsorption phase B filters condensate up to 0,01 mg/m filters solid particles reduces CO eliminates oil components reduces CO adsorbs moisture converts CO to CO <1,0mg/m 3 2 2 fractions 3 3 <0,003mg/m <–40°C 2 20,8-21,1 % 3 • The ZANDER adsorption dryers ofthe BS-MT series for breathing air are characterised by the following features: be harmful to the human organism. Compressed air from the compres-sor contains impurities such as solid particles, condensate, oil components, odour and flavour substances and other harmful gases.The ZANDER breathing air purifica-tion unit Series BS-MT dependably removes and reduces these com-ponents from the compressed air. The ZANDER microfilters Series X reliably remove the solid and liquidimpurities with 0.01 µm and 0.01 mg/m Service life Filter element 8.000 operating hours Desiccant 4.000 operating hours•Pressure dew-pointup to –40°C•Flow rate up to 6.000 m 3 filtration efficiency. The compressed air saturated withmoisture is then fed into the dryer. For the adsorption the air flows through the adsorption chamber from the bottom to the top. A spe- cial desiccant mixture retains the moisture and reduces the fraction of the various gases which could 3 /h•Pressure ratings up to 350 bar•Exceed international guidelines •Lower operating costs•Variable control•Compressor control Suitable for operation and utilisati-on in the sectors off: • Dry clean compressed air leaves the adsorption dryer. Parallel to the adsorption, regene- ration takes place in the second adsorption chamber. A partial flow of decompressed dried regenera- ting air flows through the adsorber which is to be regenerated in coun- terflow, removes the moisture picked up by the desiccant and then escapes into the open atmos- phere via the downstream muffler. The continual pressure change inoperation requires a pressure build-up during the cycles and gua- rantees pulsation free switchover from regeneration to adsorption. The activated carbon catalyst char- ge of the downstream cleaning stage removes odour and flavour substances, oil vapours, various gas fractions and carbon monoxi- de. The universal filter retains any particles of the adsorbers.
