Flange immersion heaters

Standardized flange immersion heater
DN40 to DN100

CETAL has created a new range of standardized flange immersion heaters to ensure rapid costing and optimized delivery times.

They allow the heating of liquids (water, oil, fuel oil, glycol, soda, bitumen, etc.) or neutral gas, by natural or forced convection.

They can be fitted with regulation and safety devices (thermostats, PT100 probe, thermocouple, etc.) with temperature measurement in the fluid or on the heating elements.
