HWAT Temperature Maintenance
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
