Overview air-handling ceiling systems

Capillary Tube Systems

The Capillary Mats are installed under Plaster (PP-Ultra), in Floors (PP-Floors) on Dry-Wall (PP-Combi), or they are installed in Metal Cassettes (PP-Metal) and in all room enclosing Surfaces, like Ceiling Walls and Floors.
They are then connected to the main to-and from pipes of the Hydraulic System. The Hydraulic System consists of corrosion resistant materials (PP, Copper or Stainless Steel).
The heating and cooling takes place in the same system.
The thin Capillary Tubes (3.35 x 0.5 mm or 4.3 x 0.8 mm) are set up in a parallel configuration, And they are welded to main Pipes (trunks) to form complete Mats.
The distance of the Capillary Tubes is 10 -30 mm and they are fixed by means of distance plates, called “Omega- bands”. All components of the Mats and the Fittings are made from Polypropylene.
Polypropylene –Copolimerisat ( Pandom-Copolimerisat Type 3 ) gives the Mats its stiffness, high tensile strength and ruggedness. The material has a life span of at least 50 years.

Materials made from PP conform to the fire resisting Class B2( DIN 4102 T2) and ignite normally. Because of the contents of Carbon and Hydrogen-Atoms, burning of the material does not emit Poisoned gases into the environment.

One property of the Capillary Mats is Oxygen-Diffusion through the Tubes and the Fittings. The Oxygen exchange between the air surrounding the circulating water in the system takes place until the Oxygen-Saturation point is reached. To protect the Mats against Oxygen caused corrosion and lime deposits, the Capillary Mats are separated Hydraulically from the Energy carrying circuits by the use of a Heat Exchanger. There are two hydronical systems:
The primary circuit carrying the hot or cold water and the secondary circuit with the Capillary Mats. The secondary circuit is 100% corrosion resistant, and it therefore has a long life span.
Hose System

The Hose Systems are integrated into Plaster (Single-Ultra) or Dry- Wall (Single-Combi) or into Metal Cassettes (Single-Meta). Because the system is made from Oxygen-tight material, it is possible to connect it to an existing Pipe system, even if this is not corrosion resistant.
However, we always recommend the separation of the two systems to ensure a long life span.
The advantage of the Hose system lies in it’s flexibility and its perfect fit into the entire surfaces. Changes on a short notice on the job site are no problem.
The Hose of the Single-Combi and Single-Meta –Systems is integrated into a heat distributing profile. This gives the system the best Heat – conducting properties between the Climate-system and the Hose.

Copper Systems

The Copper System is ideal for Dry-Wall ( Cu-Combi) or Metal Cassettes (Cu-Metal).
These Systems are best suitable for areas with strict fire protection regulations. Because the system is Oxygen tight, it can be connected to all existing Pipe systems.

Regulation

A corresponding regulating technology should be used to regulate the Pre-Temps for Heating and Cooling, to regulate the Room Temperature. To avoid damage to the installation, a Dew-Point
Regulator should be installed to protect against condensation in case of a drop in the dew-point.
