Product Description
| Range | Pentair Raychem HCH Sheathed Heating Cable |
|---|---|
| Model | HCH1M630 |
Raychem HCH/HCC mineral insulated (MI) Copper series heating cables are suited for use in hazardous areas. They are extensively used in a wide variety of industrial heat-tracing applications, such as long line heating or condensation prevention at low temperatures, and domestic applications, such as under floor or road and ramp heating applications. The copper heating cables with copper conductors (HCC) are available in very low resistances to allow for long line applications with a limited amount of supply points when the maximum operating sheath temperature does not exceed 200°C.
The typical maximum power output goes up to 50 W/m. Optionally they are offered with an HDPE (High Density Polyethylene) over-sheath for enhanced corrosion protection up to 80°C, usually applied when buried in concrete. For temperatures in excess of 80°C, an FEP (Fluorinated Ethylene Propylene) over-sheath is available which can be used up to a maximum temperature of 200°C.
The heating cables are offered as bulk cable as well as factory-terminated heating units to ensure optimum quality of the connections. The offering is completed with a full range of components for installation, connection and splicing of the heating cables.

Brass glands are standard on all heating units. Other materials are possible, contact Pentair for more information.
Delivery length of bulk cable on coil depends on type of resistance and is limited by max. coil length as indicated in the table on top. Factory terminated elements are limited by a max. weight of 50kg, however to ensure practical and safe on-site handling, it is strongly recommended to limit element lengths to 25 - 30kg. Not all resistances are standard items and as such may not be in stock.
Where design results in higher leakage current, the preferred trip level for adjustable devices is 30 mA above any inherent capacitive leakage characteristic of the heater as specified by the trace heater supplier or alternatively, the next common available trip level for non adjustable devices, with a maximum of 300 mA. All safety aspects need to be proven.
Also refer to the components section for more details on heating units, accessories and nomenclatures.

Frequently Asked Questions
Can I use heat trace on plastic pipes?
Yes, when using trace heating on plastic pipes ensure that ATE- 180 aluminium tape is used to help disperse the heat around the pipe.
Can you design a full surface heating system for me?
Yes, utilising our in-house design facilities, we can design your complete trace heating requirement.
Do I have to allow extra heat for pumps and valves?
If the surface area of the pump is substantially greater than that of the adjoining pipework then extra heating cable may need to be considered (depending on wattage of cable installed). Pumps and ...
Do I have to spiral the trace heating onto the pipe?
Most applications can simply be straight traced, reducing costs of materials and installation time without compromising on operational requirements.
Do I need to use thermal insulation?
Yes, thermal insulation is required on all heat trace applications. Without insulation, surface heat losses can increase approximately 4-5 times.
Does my trace heating system require maintenance?
Generally, no maintenance of our trace heating systems is required but it is recommended that the system is checked for operational and electrical integrity periodically or prior to the winter or p...
How do I terminate the heating cable?
Full termination instructions are provided with all our heating tapes
How do I test my trace heating system is working properly?
System checks depend on the system installed, constant wattage systems can be fully checked for insulation resistance and continuity. Self regulating systems can only be checked for insulation resi...
What is heat tape for water pipes?
When water pipes are exposed to cold temperatures either outdoors, underground or in small spaces, you can protect them from freezing by wrapping them with heat tape. Heating tape is actually a cor...
What is Heat Trace?
This is used for a pipe freeze protection application. Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels. Trace heat...
What is self regulating heating tape?
Self limiting / self regulating heating tape adjusts heat output to equal the heat loss from the pipe work. As pipe temperature falls the electrical conductivity of the semi-conductive core increas...
