Capillary Tube

• Tube length: 1 m
• Sensor length: 155 mm
• Sensor diameter: 4 mm

Electrical Data

• Resistor voltage:
  • 16 A at 230 V
  • 10 A at 400 V
• Inductive voltage:
  • 5 A at 230 V
  • 1 A at 400 V

Application

The capillary tube is used to start and stop the charging pump between the boiler and the circulation tank. The thermostat installed in the chimney pipe activates the pump when the temperature rises after ignition. The optimal operating temperature setting is approximately 50–120°C. After the fire goes out, the pump automatically shuts off when the chimney pipe cools down.
