Spare parts for heat tracing and frost heave protection
Identify the Correct Component
A replacement must suit the existing system. Pro Therm helps identify heating cables, connection components, sensors and controllers for electric heat tracing and existing frost heave protection systems. Type information and installation conditions form the basis of technical assessment.

Start with complete type information
Please copy the complete identification from the component. Manufacturer, type suffix, voltage and circuit reference matter more than visual similarity. Nameplate and …
Please copy the complete identification from the component. Manufacturer, type suffix, voltage and circuit reference matter more than visual similarity. Nameplate and installation photos help identification. Where markings are unreadable, existing documentation may provide further clues.

Support existing frost heave systems
For cold-store floor systems, we assess accessible controllers, sensors and connections together with the related circuits. Pro Therm provides supply, spare parts and …
For cold-store floor systems, we assess accessible controllers, sensors and connections together with the related circuits. Pro Therm provides supply, spare parts and maintenance. Scope for inaccessible cables beneath the slab is clarified from the existing system.

Structure spare-parts enquiries by component type
For a heating cable, provide type, heated length, supply, output or resistance and temperatures. For a sensor, specify characteristic, wiring arrangement, measuring …
For a heating cable, provide type, heated length, supply, output or resistance and temperatures. For a sensor, specify characteristic, wiring arrangement, measuring range and dimensions. For a controller, also include supply, outputs, alarms and the existing circuit diagram. Connection kits need the associated cable-system designation.
Add quantity, installation country, required date and photographs of existing markings. Unknown values can remain identified as unknown. A suspected replacement designation is treated as a proposal and checked technically before ordering. This improves the enquiry without promising unverified interchangeability.

Are parts from different manufacturers interchangeable?
Not universally. Technical data, connections and system requirements must match. Alternatives are assessed for the specific installation.
What helps with an unknown type?
Photos, function, installation location, wiring diagram, electrical data and plant or circuit reference. Please identify assumptions as such.
Can Pro Therm make replacement MI assemblies?
Finished soldered MI assemblies can be requested to an agreed specification. Heating length, resistance, voltage, cold leads and terminations are assessed.
Is immediate delivery available?
Availability and lead time are confirmed after identifying the product and reviewing quantity. No universal stock commitment is made.

Heating cables and assembled units
For heating cables, we need length, supply, output or resistance and operating temperatures. Finished soldered MI assemblies also require cold-lead and termination information. Replacement considers the original design; identical dimensions alone do not establish electrical or thermal suitability.
Standards reference (checked 14 October 2026): For heating cables and assemblies outside hazardous areas, IEC/IEEE 62395-1:2024 is the international reference for general requirements and testing. Germany still lists DIN EN 62395-1:2014-10 as the current national edition.
Connections and fixing components
Connection kits, end seals and glands are assigned to the specific cable system. Ambient conditions, temperature and hazardous-area requirements may further limit selection. Fixings must suit the surface and duty. Mixed products require compatibility assessment rather than arbitrary combinations.
Choose compatible sensors and controllers
Sensor characteristics, range, supply and output function determine suitability. Controller replacement also needs assessment of alarms, limiting and switching capacity. Wiring diagrams help comparison. The same enclosure or number of terminals does not establish compatibility.
Standards reference (checked 14 October 2026): For industrial platinum resistance sensors such as Pt100 or Pt1000, IEC 60751:2022 defines the resistance relationship and sensor requirements; the German adoption is DIN EN IEC 60751:2023-06. Wiring arrangement, accuracy and installation are selected for the measurement duty.

Standards reference (checked 14 October 2026): IEC/IEEE 60079-30-1:2025 and IEC/IEEE 60079-30-2:2025 are international references for resistance trace heating in hazardous areas. Germany still lists DIN EN 60079-30-1:2018-04 and DIN EN 60079-30-2:2018-04 as current national editions. Equipment group, permitted EPL, protection concept and evidence for the actual assembly determine suitability.
