ELEKTRA FreezeTec™ is intended for protection of pipes and valves
susceptible to damage caused by low temperatures. The system may be used
only when the following conditions are met:
external diameter of pipe to be insulated should not exceed DN 50 mm;
pipe insulation thickness should be between min. 10 mm and max. 20 mm;
temperature of the protected pipe should not exceed +65°C;
min. ambient temperature - 25°C.

Page 4: Installation Preparation
Installation (Preparation) Before the cable set is in place, the length of pipe to be heated should be measured in order to select the length of heating cable (Table 1) using a co- efficient (Table 2) which will depend on the following:... - Page 5 Fig. 1 STAGE 2 The ELEKTRA FreezeTec™ heating set is laid along the pipe as shown on the Drawing (Fig. 2a) or helically wound around the pipe (Fig. 2b). Method used to lay the cable (along or helically around the pipe) depends on the selected length of heating cable.
- Page 6 The value of coefficient (Table 2) for the a.m. parameters is 1.5. Therefore, the length of heating cable will be: 1 2 m x 1,5 = 18 m. ELEKTRA FreezeTec™ 12/21 heating cable 21 m long is selected. The cable should be helically wound around the pipe.
- Page 7 In the a.m. example: - outer diameter of pipe is 4.2 cm - dimension of heating cable is 5 x 7 mm - heating cable length is 2100 cm - pipe length is 1200 cm Thus, the cable has to be wound around the pipe so that the distance between cable runs is about 11 cm.
- Page 8 To prevent possible displacement, the cable should be fitted with extra tape lengths. STAGE 3 After the ELEKTRA FreezeTec™ cable is placed on the pipe, it must be fixed with self-adhesive aluminium tape along the whole cable length.
- Page 9 NOTE: If plastic pipes are to be heated, then the self-adhesive tape should be used under the cable. The use of aluminium adhesive tape ensures that the cable adheres to the pipes securely and accurate heat transmission is facilitated. The tape also prevents the cable from being pushed into the thermal insulation, which could cause possible overheating.
