  • Page 8 BX CNDU Tumble Dryer 4.1. Condanser Dryer Working Principles: • Firstly, the process air is sucting from ambient it goes to the electrical heater • The process air is heated in the electrical heater and directed into the drum • The hot and the dry air goes through the drum, it interacts with laundries and takes out the humidity from them.
  • Page 9 BX CNDU Tumble Dryer CND Ecosense Working Principles: In all sensor dryer we use a humidity plate(two metal strip) on front-bearing. When wet or dry clothes touch this plate, we can read a resistance by electronic card. And thus, we can understand the dryness level of clothes. When this level reaches to the limit(already determined) heater are off and cooling period occurs.

  • Page 11 BX CNDU Tumble Dryer 4.2. Components Related to the Drying Cycle: 4.2.1. Heater: Two circuit open spiral wire type heater is driven by the 2 relays. A manual resettable thermostat is used on these heater, in order to provide IEC safety rules accordingly. This manual resettable thermostat cut the heater power at prescribed temperature and can be resetted by pressing the button on thermostat, so heater can be used after a failure bacause of thermostat is open circuit.
