Create your own esPRO® Inline Heater.
The esPRO® Inline Heater LH is a remote heater using an electrical resistive element heater. It is intended to safely heat acids, bases, DI water and other noncombustible liquids up to 160°C.
The Inline Heater LH Series is designed to be used in an ultra-pure environment, such as manufacturing equipment for the Semiconductor, Electronics, LED/Flat Panel, Solar cells, Chemical Processing, Aerospace and Life Science industry. It is not to be used in non-industrial, food and consumer products and applications. It is also not designed to be used to heat gases.
The Inline Heater LH is intended to be mounted vertically, with IN and OUT connection ports located either on the top, top sideways, bottom sideways or bottom of the cylindrical housing. It is not intended to be used in any other angle.
The Inline Heater LH Series is available in different type variants, according to customer needs:
Features
- Unprecedented flexibility for space saving installation and cost efficient solutions based on the individual heating application requirements.
- Embedded Temperature sensors for the
- heater element and liquid overtemp (additional sensors for process control available)
Heating process
The process liquid is supplied to the Inline Heater LH via the IN-connection. The process liquid is guided along an electric resistance wire, which is electrically and chemically insulated by a chemical resistant fluor polymer. The resistance wire is designed to heat up when electric current is applied. The heated resistance wire is allowing to exchange the thermal energy with the surrounding process liquid. This way, the inline heater can be used to heat the process liquid to the desired temperature.
Liquid overtemp sensor:
The temperature of the process liquid can be measured with the integrated process temperature sensor, which is mounted inside the inline heater near the outlet connector. The liquid temperature needs to be kept below its boiling temperature at the given altitude or pressure.
Embedded thermocouple:
The temperature of the resistance wire needs to be measured by the embedded thermocouple, which acts as the safety overtemperature sensor. A maximum wire temperature of 220°C should not be exceeded.
Capacitive liquid present sensor
The inline heater can be equipped with a liquid present sensor, which can be used to detect if the process liquid has filled the whole volume of the inline heater before the heater is activated. Inline heaters require a minimum flow to be controlled at the outlet of the heater. The liquid present sensor is not required for inline heaters.
Ground wire with Ta-tip or Pt-tip:
An insulated ground wire with a chemically inert metal tip in electric contact with the process liquid is used to detect leakage current between the heater element and the process liquid.
Vent port:
The thermal expansion of the process liquid in contact with the heater element may lead to local gas bubble formation. The user needs to make sure that the liquid is carrying those bubbles away from the heater element by providing a minimum flow of the process liquid. The gas bubbles can be vented through the vent connection at the top of the heater.
