ELSR Ramp Self Limiting Parallel Heating
Self-Regulating Heating Cable - ELSR Ramp Self Limiting Parallel Heating
It is used in the areas of frost prevention, open areas, car park entrances and exits, helicopter landing areas, concrete ramps, stairs and walkways.
ELSR Ramp
This heating cable is designed for easy and safe installation of open-space heaters. Accidents due to frost and snow are prevented all over the heated space. To ensure a high mechanical load capacity in open space, the eltherm engineers developed this heating cable especially robust. Suited for installation in sand/cement mixtures
Advantages:
- Highly robust
- Suited for hardest installing conditions
- Flexible mounting
- Radially and longitudinally waterproof, outer jacket is strongly grouted with protective braid
Applications:
- Parking garages entrances and exits
- Helicopter landing sites
- Concrete ramps
- Stairs and footpaths
Electrical protection
Maximum heating circuit length
According to local standards and regulations.
Take into account the conductor size and max. permitted voltage drop.
A higher voltage drop can occur at start-up of heating.
Power at start-up
To determine the installed power with the electrical system designer, the nominal current of the series connected fuse or the current value at the system start-up temperature must be taken into account (e.g. 32 A for 55 m ELSR-Ramp (–10°C).
Residual current device (RCD) 30 mA required, max. 500 m heating cable per RCD.
Remark
For the use of standard control cabinets, the maximum heating circuit length of 55 m at 32 A per heating circuit must not be exceeded
