Tube heater

for gasfor liquidscirculation

Overview
A through-flow heater provides direct heating of liquids, oils and gases while they flow through the tube. Designed for industrial in-line applications, these heaters raise the medium to the required temperature at the outlet and can be configured as lower-power circulation heaters when the medium recirculates.

Design and components
A standard through-flow heater includes the tube, inlet and outlet connections, electric heating elements, flanges and connection boxes. Configurations can incorporate thermal insulation, thermostats, temperature sensors, flow and pressure sensors, and overheat protection to meet process specifications.

Control and service
Control is typically done via a separate control cabinet or a control panel connected to a PLC. For lower-power or simpler installations, a mechanical thermostat may be used. Engineering support for control system integration, installation and preventive maintenance is available.
