Tracer Heating

Conduits, valves, fittings, contains and much more heated electrically!

Used as frost protection to prevent water pipes, valves, water meters and other facilities from being damaged by frost. To maintain the temperature level: liquid substances such as chocolate, oils, and fats must always be maintained on a constant temperature level, e.g. when temperatures drop or in the idle status. To heat up: various media - e.g. in the industry sector - must get heated to a certain level.

Whether in a private household or in an industrial plant: there are many good reasons for installing trace heatings.

Heating cables used for frost protection

SiPCPS/E (acc. to VDE 0253)
Application: Trace heating for water meters, valves, fittings, containers, and oil pipelines.
Delivery range:

Ready to connect: 2m PVC connecting cable, one-sided
Dimensions: approx. 10 x 6.5mm
Power: 20W/m max.
Length: as required
Voltage: 230V and others
Temperature stability: up to 90 °C

 

Special designs:
Extended connecting cable or connecting cable with different insulation (e.g. rubber, PUR…); connecting cable with right-angle plug or customized special plug; different voltages, e.g. 400 volts or low-voltage design.

 

SiPCPS/E-A
Trace heating as described above. With control knob (+5 °C) in the end sleeve. Frost protection for water and heating oil pipes.
Additional applications: aquariums, terrariums, hotbeds, narrow gutters or down pipes, and much more. Please enquire for your special application.

Heat requirement, planning: The heat loss depends on the diameter of a pipe (NW in millimeters), the strength, and the thermal conduction coefficient of the insulation and the temperature difference (K) between pipe and environment. A trace heating is used to leverage this heat loss.

 

Which pipe temperatures must be achieved?

0°C:       Used to protect heating oil pipes from coagulating

+5°C:     Frost protection for water pipes

+50°C:   To protect grease pipes such as kitchen drains from being blocked by deposits

+80°C:   To protect heavy oil pipes between burner and oil pre-heater

 

The following details are required for the planning:

  • Pipe length and pipe diameter
  • Pipe material and pipe thickness
  • Type and thickness of the insulation
  • Type of liquid, e.g. water, oil or fat
  • Type of heating, i.e. to be used as frost protection, to be used for maintaining the temperature or for warming up.

 

Performance calculation

Example: Water pipe NW50, 10m long, frost protection up to -25°C min., insulation approx. 30mm.

 

Key to figure above:

Wärmeverlust in Watt pro Meter Rohr     Heat loss in watts per meter pipe length
Temperaturdifferenz in °C                         Temperature difference in °C

Requirement:

  • 1 SiPCPS/E heating cable, 10m long, 230V, approx. 15W/M
  • 2m cold end, adhesive aluminium foil for assembly, 1 controller

 

 

Assembly and insulation: Install heating cables as a single or multiple layer across the length of the pipe according to the pipe thickness and the required heating power (see fig. 1 and 2) or wind heating cable at regular intervals around the pipe (see fig. 3).

Key to figure above:

Rohr                 Pipe
Heizkabel        Heating cable
Aluklebefolie   Adhesive aluminium foil
Fühler               Sensor
Isolierung         Insulation
Aluklebefolie   Adhesive aluminium foil
Heizkabel        Heating cable

Attach heating cable and sensor complete with adhesive aluminium foil to the pipe. The adhesive aluminium foil must be used for assembling the device as it ensure the optimum contact between pipe and heating cable.

Once the heating cable has been installed, the pipes must be covered with commercially available insulation material.

Important! When installing heating cables on plastic pipes or plastic parts, there may be no direct contact between cable and parts. The cables must be wrapped with adhesive aluminium foil before being installed. Any electrical connections must be performed by an approved electrician in
compliance with the VDE regulations!

 

Heating cables for various applications

PVC heating cable, up to 90°C

Connection at both ends, to be used e.g. for thick pipes. Multiple parts attached to tube, to be used as frost protection for pipes with branches and for container heatings.

 

Silicone heating cable from -60°C to +180°C    

To be used with higher temperatures: heavy oil and fat pipes, container heatings, valves, glue tubes, etc.

 

Teflon heating cable, from -190°C to +260°C    

To be used for high temperatures or aggressive substances, e.g. in chemical factories.

 

Self-limiting heating bands    

Anti-freeze heating or in the place of warm water circulation lines.
