nVent RAYCHEM S-21 trace heating splice kit

nVent Raychem S-21 trace heating splice is a hot applied low profile splice kit designed and approved to splice Raychem QTVR self regulating trace heating cable in industrial ATEX hazardous area locations. The Raychem S-21 is approved by PTB and Baseefa for use in ATEX hazardous locations zone 1, zone 2, zone 21, zone 22 and suitable for temperatures ranging from -40°C to +45°C.

The unique design of the Raychem S-21 suits the demands of ATEX hazardous area locations and the industrial environments. The low profile splice kit employs easy to use heat-shrinkable tubing with an adhesive, that when heated forms a semi-flexible moisture proof encapsulation over the join of Raychem QTVR trace heating cable. Electrical continuation is maintained via crimps for the conductors and a solder connection for the braid of the trace heating cable. Due to its low profile design the S-21 trace heating splice kit can be installed under insulation directly on the pipe or other surface.
