  • Page 16: Technical Product Description

    To this end, the two chambers alternate between different operating modes. Whilst in one vessel, compressed air is de-humidifi ed (adsorption), in the other vessel the humid drying agent is prepared for another charge (regeneration). These two states, which run in parallel during compressed air preparation, are described below. K-MT 1-8/D3...
  • Page 17 This separate regeneration air fl ow is fed through the depressurised chamber. The humidity stored in the drying agent is taken up by the air fl ow and expelled into atmosphere via the muffl er. Here, regeneration is shown in the right vessel. K-MT 1-8/D3...
  • Page 18 When the drying agent in the adsorbing chamber has taken up a suffi cient level of humidity, then the switchover between the vessels will be effected between the vessels. Following switchover, the above-described process is repeated, with the adsorption and regeneration now taking place in the respective different vessel. K-MT 1-8/D3...
