SUPPLEMENTARY HEAT IN VAULTS AND FOUNDATIONS
With heating cable installed directly in the concrete, any damage and delay due to low temperatures will be eliminated.
The concrete hardens evenly and fast, the forms can be removed after 24 hours and painting can start considerably earlier.
By measuring the temperature in the concrete and controlling the power to the heating cable, the process of hardening can be controlled in order for the concrete to achieve the maximum strength.
With its low running charges and easy installation this is an extremely effective way of saving and a good insurance against the impact of winter on constructions strength and against waste of time. An insurance well worth its price.
After casting, the heating cables can be used as a source of heat to get a quick drying-out and to keep the construction warm.
The heating cable loops are made from TSF-cable which is designed for this purpose. They are supplied in two different standard lengths, 40 and 95 metres respectively.
The loops are delivered as double-coiled loops with connecting devices (CEE) fitted.
|Length||Type of cable||Power||Voltage||Part.no.|
|45 m||TSFR 0.82||1435W||230V||89 871 11 with built-in return-wire|
|95 m||TSF 0.18||3100W||230V||89 871 12 without built-in return-wire|
|95 m||TSFR 0.18||3100 W||230V||89 871 13R with built-in return-wire|
From the table below one can easily find how large a surface each loop will cover for a required output (Watt/m²) .
Thereafter you calculate how many loops needed.
Normal output: 120 watt/m².
|Required power||c/c-distance (cm)||Covered surface (m²)|
|W/m²||40 m||95 m||40 m||95 m|
