5 reasons for system solutions from BEKA
The underlying principle behind cooling and heating ceilings applies irrespective of the system and is based on transporting heat by means of thermal radiation and convection. All three product ranges from BEKA for installing cooling ceilings – BEKA capillary tube mats, BEKA serpentine copper tubing and BEKA single pipe technology – are water-based (hydronic) systems.
Although metal has traditionally been used in industry for producing pipes, plastics are also now being increasingly deployed. Both plastics and metals (predominantly copper) have been successfully used for many years in cooling and heating ceilings. All these materials have proven themselves on the market over many years.
BEKA produces the capillary tube mats with more than 30 years of experience from pure polypropylene. The material is easily recycled and very resistant. Since the capillary tubes are produced with a wall thickness of only 0.5 mm, the slightly poorer thermal conductivity of plastic relative to metals is not a disadvantage. The large number of parallel, closely aligned capillary tubes generates equally high cooling and heating outputs.
BEKA serpentine copper tubes are bent from soft tempered (R220), Cu-DHP copper pipe to EN 12449 standard. Copper as a material is highly valued for its intrinsic quality and excellent thermal conduction properties.
While plastic pipes have clearly dominated in underfloor heating systems for many years, equivalent and even higher-quality plastic pipes are still not widely used in chilled ceilings. The BEKA single pipe technology system utilises modern, PE-RT 5-layer composite pipes that are diffusion-tight according to DIN 4726 ISO 24033/22391/21003.

Whether BEKA capillary tube mats, BEKA serpentine copper tubing or the BEKA single pipe technology should be selected for a cooling and heating ceiling can only be clarified by considering the specific overall conditions relating to the project. In addition to the actual cooling output that needs to be provided by the system, issues relating to the ceiling design, use of space and, of course, the specific costs of the investment also need to be clarified. The three product groups differ in regard to these three aspects. However, it is precisely these product-specific differences that enable a conscious decision in favour of a technically and economically optimised solution. As a manufacturer of the three product lines, we can offer effectively neutral advice purely aimed at optimising the required solution. BEKA’s technical support service will be happy to provide you with the product-specific information you require.
In addition to these essentially technical- and economic-based criteria, key people involved in the project may also have valid arguments for or against a system solution based on their own personal experience or even emotive reasons. To find this out, an open consultation between the responsible persons is absolutely recommended. Ultimately, it is always a question of selecting and defining the technical variant that meets the wishes of the client and fits the accepted cost frame.
