HM403 and HM403T

HM403 and HM403T models are a semi-automatic, three-channel heat treatment units for preheating and annealing metal workpieces.
Difference between HM403 and HM403T models is in output power regullation:
- HM403 is equipped with contactors
- HM403T is equipped with thyristors

Programming alternatives

HM403/HM403T has three conventional controllers for temperature regulation. The controllers operate with or without a thermocouple. Temperature is registered on a separate temperature recorder. The signal light for HM403T will indicate any disturbances in the electrical network and/or the heating resistors. Locating the disturbance is easy and therefore problems can be solved fast.

Heating process can be carried out with or without a thermocouple. If needed, the temperature can be recorded using a separate temperature recorder. A mains current socket provides power for the unit, which means that short cables can be used.

HM403TA has one processor regulator, which is used for adjusting heat treatment parameters.
When using a thermocouple, the regulator shows the temperature and the following parameters can be adjusted:
* Heating rate [°C/h]
* Holding temperature [°C]
If a thermocouple is not in use, the so-called percentage system is applied, whereby the heating power is regulated in percentage ratio and the temperature is measured with an external measuring device.
