Heating systems protect pipes, valves, actuators and other elements vulnerable to harmful influence of low
temperatures, against the coldest winter conditions. Financial losses incurred due to damaged pipes and valves may even exceed investment costs of entire heating systems.
These heating systems are used for preventing frozen:
- water fixtures,
- sewage systems,
- sprinkler systems,
- air conditioning and ventilating pipe systems.
All metal (steel, copper, iron) and plastic pipes and tubes can be heated.
For pipe and pipeline heating, the following can be applied:
- constant wattage heating cables ELEKTRA VCD10 and ELEKTRA FreezeTec®, with constant heat output per metre,
- self-regulating heating cables ELEKTRA SelfTec®, with heat output matching the outside temperature variations.
Snow and ice protection
Protection of roofs, gutters and downpipes. Snow and ice protection systems protect against:
- snow and ice build-up on roofs,
- damage caused by ice build-up in gutters and downpipes,
- unsightly water damage on building walls,
- icicle formation.
For protecting roofs and their elements, heating cables with UV-resistant outer sheath need to be applied:
- ELEKTRA VCDR heating cables,
- tough ELEKTRA TuffTec heating cables,
- ELEKTRA SelfTec® and SelfTec®PRO20 self-regulating heating cables.
When heating external areas, it is required to assess the required heat output value per m2. Recommended heat output depends on the regional climate conditions, i.e. minimum ambient temperature, snowfall intensity and wind strength.
For heating external areas, the following options can be utilised:
- ELEKTRA VC20 single-side supplied heating cables (power output 20 W/m),
- ELEKTRA VC25 single-side supplied heating cables (power output 25 W/m),
- tough ELEKTRA TuffTec heating cables (power output 30 W/m),
- ELEKTRA SnowTec® heating mats, made from ELEKTRA VCD heating cable (mat’s power output 300 W/m2),
- tough ELEKTRA SnowTec®Tuff heating mats, made from ELEKTRA TuffTec heating cable (mat’s power output 400 W/m2).
Short, tight construction deadlines force contractors to execute construction works regardless of current weather conditions. When pouring concrete in temperaturesbelow 0°C, it becomes vital to protect freshly poured concreto mixtures against freezing to ensure optimal conditions for the chemical reactions between cement and water, which constitute a crucial factor influencing resulting mechanical strength of concrete.
ELEKTRA BET heating cables are designed to protect concrete mixtures poured and curing in temperatures below 0°C.
