CBM Self-regulating heating cable K55A100 (100m coil)

HEATING CABLES K55A-K65A SELF-ADJUSTING HEATING CABLES TO MAINTAIN THE TEMPERATURE OF FLUIDS - HIGH TEMPERATURE SYSTEMS ■ Suitable for maintaining the temperature of liquids in the pipes, for example, domestic hot water ■ It can maintain the pipes at a temperature above 70°C, thereby avoiding the formation of Legionellosis bacteria ■ Optimisation of energy consumption thanks to the self- adjusting feature of the cable CODE Cable Power Maximum Maximum Minimum Maximum length length room room installation of the heating circuit temperature temperature room from the supply point powered not powered temperature K55A100 100 m 9 W/m 55 °C 80 °C 100 °C -20 °C 130 m K65A100 100 m 13 W/m 65 °C 80 °C 100 °C -20 °C 110 m HOMOLOGATION AND STANDARDS OPERATION ■ CSTB ■ The heat emission varies automatically without control thermostats being used. They are based on the property of some polymers, with which the conductors are insulated, to vary their resistance according to the temperature which they are subjected to; ■ Using a thermostat (L03BI1A) allows periodic heating of the system to be guaranteed or to maintain the system temperature constant. 1 K55A-K65A - SELF-ADJUSTING HEATING CABLES TO MAINTAIN THE TEMPERATURE OF FLUIDS HIGH TEMPERATURE SYSTEMS INSTALLATION ■ The heating cable can be secured linearly according to the diameter of the pipe; ■ The cable can be cut to the desired length directly during installation; ■ Minimum bending radius: 27 mm; ■ The power of a metre of cable varies with the room temperature; ■ The total power depends on the length of the heating cable. The heating core is active along the entire length of the cable, therefore, a cold tail end must be created so as to have a section with cold terminals (using the KIT2A); ■ Secure the cable to the pipe with the relevant fixing Ø PIPE INSULATION THICKNESS tape K50 for steel pipes or K50AL for plastic pipes; mm inches mm ■ It is advisable to apply an insulating coating over the heating cable for an effective system. 10 1/2 19 20 3/4 19 25 1 19 32 1/4 25 40 1 1/2 30 50 2 40 60 2 1/5 50 The table shows the insulation thickness that is required to ensure the temperature in stainless steel and galvanised steel pipes is maintained with a minimum room temperature of +18°C and a thermal conductivity coefficient of 0.035 W/m.
