Description:
Flow-through Heating Units are used for the direct heating of liquids and gases. The design of the heaters is based on general conditions (type and properties of the fluid, temperature, pressure, etc.). The units are made from tubular or ceramic heaters housed in protective casings that are welded to a flange. The entire assembly is placed inside a protective tube and finished with a control box with a protection rating of IP54 or IP65.

Control / Regulation
Flow Heater Units can be equipped with a built-in control system (for low power) or a separate external control cabinet. The heating power can be divided into one or several heating sections.
A. Temperature Controllers:
- Electronic ON/OFF control
- Thyristors
- Capillary thermostats
B. Sensors:
- PT100
- Capillary temperature limiter
- Other thermocouples
