Pipework shall be traced with appropriate wattage tape, secured in accordance with the manufacturers recommendations. All connections to be made using the RayClic system.

components: 

CE Connection and End Seal Kit

nVent RAYCHEM CE20-01, CE20-03 and CE25-01 are heat shrink polymer kits used to connect and terminate select nVent RAYCHEM self-regulating trace heating cable. Requires wire stripping and a heat gun. Each kit contains connection components for a cable termination and end seal.

RayClic Connectors

nVent RAYCHEM RayClic connection system is a simple, fast and reliable set of connection kits developed for select nVent RAYCHEM XL-Trace, IceStop and HWAT self-regulating heating cables. No heat guns or wire stripping are needed, because insulation displacement technology is used to make the electrical connection.

Fixing Tape

nVent RAYCHEM GT-66 is a glass installation tape to attach trace heating cables to pipes.

HWAT L/M/R Heating Cable

nVent RAYCHEM hot water maintenance (HWAT) solutions provide a smart and simple single pipe alternative to the traditional method of hot water recirculation.

recommended insulation thickness in mm (particular project specifications may differ): 

HWS (55 deg C)

Raychem recommendations

15 - 22mm = 20mm thick, 28mm = 25mm thick

35mm = 30mm thick, 42mm = 40mm thick

54mm = 50mm thick

All based on mineral fibre insulation thermal conductivity = 0.035 W/mK
