DEVImulti™ PVC

DEVImulti™ PVC is a high-quality, 4-conductor cable with an outer sheath made of PVC and specially designed for frost protection of long pipes. Additionally cable is used in multiple outdoor ground, frost protection, etc., applications.

The cable is constructed of 4 identical conductors. The conductors can be connected in diﬀerent ways (parallel and/or serial), meaning that the same cable can provide up to 11 diﬀerent outputs, depending on the connection made.

DEVImulti™ PVC is very ﬂexible and therefore perfectly suited for external installation on pipes, it can be supplied in 3 versions with diﬀerent resistance values.

The cables are not approved for use in contact with water for human consumption. DEVImulti™ can be customized for the speciﬁc project, depending on voltage, required

output, length of heating cable and length of cold leads.

Note: It is the full responsibility of the installer/designer to use proper cold lead dimensioned for the purpose and assembly sets that establish suﬃcient

mechanical strength, ﬂammability resistance and water tightness - and to design the heating unit with correct output for the speciﬁc application to avoid overheating of the cable or building materials.

Beneﬁts:

• Easy to install

• Various Ohmic output

• Safe and robust

• Long life-time

Standard compliance:

• IEC 60800:1992

• EN 50581:2012

Always remember thermostat control – sensor placed on / in media. Notice: plastic pipes can melt at too high cable linear output and max. 10 W/m should be recommended.

Ohm values and lengths for couplings 1-11 with diﬀerent outputs for for 4-conductor heating cable

Coupling 1-10: 1 phase / 2 phase. Coupling 11: 3 phase (Y connection type).

When designing and selecting the coupling method, ensure that the load is distributed equally between heat conductors as much as possible. Connection to one cable side marked “T” – twin connection end, connection to two cable sides marked “S” – single connection ends.
