Fibre glass re-enforced high load junction box for HEW-THERM XPI and Pyrotenax MI trace heating cables. This junction box is used to make reliable connections between cold lead cables and a power cable when the load exceeds the ratings of the JB-EX-21.
The JB-EX-21/35MM2 has 6 entries to enable tri-phase connections and allows for a load of 100A in any configuration (star and delta).
The box is intended for wall mounting.
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...
