Thyristor control units
HTM's control units are normally designed to meet the requirements of the particular furnace type.
Our customers may choose from a wide range of temperature controllers available in the market and decide for a trusted manufacturer.
Controllers with different comfort features are available, such as:
- Set point controllers;
- Program controllers with 8 or more program steps;
- Program controllers for up to 10 parameters;
As far as possible, controllers for supply media, drives and vacuum pump stations are incorporated in the control units.
Control units using one or more thyristors as a power control, are suited for heaters with transformers or with high hot/cold resistance, e.g. for the LOSIC and LORA standard furnaces.
