Concrete Component Activation, Yes – but Not Concrete Core Activation
Near-Surface Concrete Component Activation
Near-surface concrete component activation with BEKA capillary tube mats or BEKA single pipe technology is the clear answer to the weaknesses of concrete core activation with thick tubes located in the middle of the component structure.
Near-surface concrete component activation with BEKA capillary tube mats or BEKA single pipe technology responds comparatively quickly to temperature changes and achieves sufficiently high cooling and heating performances.
Concrete Component Activation with BEKA Capillary Tube Mats
In the case of near-surface concrete component activation with BEKA capillary tube mats, the narrow capillary tubes with an outer diameter of only 4.5 mm lie just a few millimetres above the finished concrete surface. In this method of construction, which has been verified through considerable practical experience, the capillary tubes have proven themselves even under these challenging operating conditions and complex building procedures.
It is possible to activate both in-situ concrete ceilings and precast concrete elements produced in the concrete factory.
Advantages of Near-Surface Concrete Component Activation
- Responds quickly to temperature changes
- Utilises the construction component to store energy
- High cooling and heating capacities
Near-Surface Concrete Component Activation with BEKA Single Pipe Technology
The BEKA single pipe technology is suitable for installing near-surface concrete component activation systems under difficult site conditions and at low ambient temperatures. The robust and durable PE-RT pipes remain flexible even at low outside temperatures and are not liable to fracture.
The single pipes, which are just 10 mm thick, lie below the top reinforcement and thus close to the finished surface of the concrete floor slab. This therefore ensures a rapid thermal response by the floor slab. For the same supply temperatures, significantly higher cooling and heating capacities are achieved than with conventional concrete core activation (CCA) with thick tubes.
The technology is suitable for installation in in-situ concrete ceilings as well as for thermally activating precast concrete elements.
Near-surface concrete component activation with BEKA capillary tube mats or with the BEKA single pipe technology. The heat-conducting tubes always lie immediately above the finished concrete surface. This makes this technology thermally responsive and energy efficient.
