Ex-flow heaters
Description
EX-Flow Heaters are used for direct heating of liquid and gas liquids. The design of the heaters is based on the general conditions (fluid type and properties, temperature, pressure, etc.). The assemblies are made of tubular or ceramic heaters in shields that are welded to the collar. The whole is placed in a protective tube. They are terminated with a control box with IP54 or IP65 protection.
Application
- drinking water, circulating water, deionized water, demineralized water, etc.
- hydraulic oil, lubricating oil, cooking oil, heating oil, bitumen, etc.
- air, natural gas, exhaust gases, nitrogen, etc.

- electronic ON / OFF control
- thyristors
- thermostats with a capillary
B. Sensors:
- PT100
- temperature limiter with a capillary
- other thermocouples
