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.

We make every effort in answering your questions. Below is a list of those questions we are frequently asked. Click on a question to expand its answer.
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...
Yes, utilising our in-house design facilities, we can design your complete trace heating requirement.
Yes, when using trace heating on plastic pipes ensure that ATE- 180 aluminium tape is used to help disperse the heat around the pipe.
Yes, thermal insulation is required on all heat trace applications. Without insulation, surface heat losses can increase approximately 4-5 times.
Most applications can simply be straight traced, reducing costs of materials and installation time without compromising on operational requirements.
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 ...
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...
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...
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...
