Product overview
EM4-CW is a constant output heating cable for simple, fast, and effective ramp and accessway heating to prevent snow and ice formation.
The pre-terminated EM4-CW cable comes complete with a 4m cold lead, removing the need for on-site termination activities. Simply install the heater over the required area and connect the cold lead to the power junction box and “Smart” control unit.
The EM4-CW heating cable is designed for applications where a 3 phase (400V) supply is available.
Key Benefits:
- Robust constant wattage heating cable with 25 W/m output.
- Pre-terminated with 4m power cable to avoid on-site cable splicing/connection.
- Maintenance-free: no moving parts.
- Available in many sizes to fit your application.
- Combine with VIA-DU-20 controllers and SBS-xx-CW-40 multi-circuit control panels for increased energy efficiency .

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...
