YZDC series microcomputer bearing heater is an upgraded version of the ELD series bearing heater, electrical parts using the most advanced chip micro-processing technology, rugged design for continuous operating conditions to provide a safe and reliable guarantee. The microcomputer control technology for heating control of the whole process, to achieve a heater soft start, soft stop, automatically adjusts the output power, automatic detection program, a self-test failure heating devices work, as well as non-work state diagnosis and protection. Heating temperature and time can be pre-set and displayed, cylindrical Peng expansion, in the same hole, to become part of the production line of a process, significantly reduce production costs. Special design provides a higher effect at lower consumption, save energy. To increase the power or the size of all or ordered upon request.
