Concrete heater

KDBS KDBS
  • effective and cost-efficient method of concrete heating at low temperatures
  • possible to carry out monolithic concrete works all year round
  • acceleration of concrete setting
  • stable power and equal heating without boiling and wires burn-out
  • simple installation and connection
  • no electric transforme
  • optimal line of sections
  • high mechanical resistance of the cable
  • bestfor columns, beams, technological grouts

Purpose

The heating cable is laid on the carcassof an object to be concreted. After concreting in a timbering, a cable is con-nected to electrical network. The KDBS cable, demonstrating its heating features, dries theconcrete in time required, according to the operation requirements and sizes of theconcrete construction. After drying, the cable is disconnected from the supply network, ends are to be cut and it is left inside a concrete construction.

Structure

The KDBS section consists of a double-core cable connected with an installation wire by using a con-nection coupling. On the other side, the section has an end coupling. Couplings ensure the connection hermeticity.

Single- and multi-wire cores made of various materials and alloysInner insulation – polyethylene composition

Screen – copper drainage core and aluminized polyethylene tape Outer jacket – PVC-plastic
