heating and cooling ceiling with capillary tube mat OPTIMAT SB 20.00

system description

Design
The capillary tube mats are plastered directly underneath a concrete ceiling. On the visible side, a closed, jointless plaster ceiling is created for the dissipation or supply of sensitive heat loads. The water circulates noiselessly in the capillary tube mats and regulates the room temperature largely by radiation, partly by convection.

Capillary tube mat
The Clina capillary tube mat OPTIMAT SB 20.00 is recommended for this design.

Length & Width
The capillary tube mats are custom-made in length and width for each project. On the construction site the mat distributor pipes are connected to each other by heating element socket welding. This is a secure, non-detachable connection.

Hydraulic connection
Mat distributor pipes and supply lines are accommodated in the the suspended ceiling of the corridor, a slot or a decking at the front of the room. The capillary tube mats welded together to form a hydraulic circuit are connected to the flow and return lines.

Of course, the ceiling void can also be used for further installations.

Mounting
The capillary tube mats are fastened, depending on the nature of the subsurface, either with Clina Optifix, double-sided adhesive tape, Knauf plaster pins or a full-surface plaster base.

Lamps & Ventilation
Larger openings must be considered in the planning phase. Up to approx. 100 mm, openings can also be realised during the construction phase by simply pulling the capillary tubes apart.

Plaster
All commercially available plasters such as gypsum, lime, cement or acoustic plaster are suitable. For example, they are applied using the spraying method up to a plaster layer thickness of 15 mm.

Regulation
The system can be regulated room-by-room.

Fields of application
Suitable for all types of buildings, such as office buildings, residential buildings, hotels, etc., whether new construction or renovation.

The capillary tube mats are plastered directly underneath a concrete ceiling.

Mat distributor pipes and supply lines are accommodated in the the suspended ceiling of the corridor, a slot or a casing at the front of the room.

The capillary tube mats are fastened, depending on the nature of the subsurface, either with Clina Optifix, double-sided adhesive tape, Knauf plaster pins or a full-surface plaster base.

Plaster, for example, is applied using the spraying method up to a layer thickness of 15 mm.

recommended capillary tube mat

The OPTIMAT SB 20.00 consists of 2 round mat distributor pipes (20 x 2,0 mm) and capillary tubes
(4,3 x 0,8 mm).

The constant distance between the capillary tubes (centre distance) is 20 mm and is guaranteed by the omega ribbons.


Special features

  • high mechanical resilience
  • low pressure loss
  • good venting

advantages

Cooling and heating with one system
In most buildings, the heat requirement to be covered is so low due to the well-insulated building envelope that capillary tube mats invisibly integrated into the ceiling not only provide excellent cooling in the summer, but can also be used to heat very comfortably and energy-efficient in the cold season.

High performance and dynamics
Due to the capillary tubes completely enclosed by the plaster, a large-area heat conduction is achieved. The near-surface layer with a low plaster coverage ensures a fast response. This design allows a maximum degree of activation of the ceiling.

Good price/performance ratio
The use of large-sized capillary tube mats reduces the installation effort. The usual plaster layer thickness is not affected by the capillary tube mat. There are no additional costs for material.

Very low installation height
A complete embedding of the capillary tubes is achieved with a plaster layer thickness of 10-15 mm. Mat distributor pipes and supply lines are accommodated in the the suspended ceiling of the corridor, a slot or a decking at the front of the room. Ideal for maximum utilisation of the building height.

Very flexible
This design can be adapted to all spatial conditions, e.g. also to spaces with vaults and archs.

Individual room control
The system can be regulated room-by-room.

Better than component activation
The plaster ceiling convinces with significantly higher dynamics, performance and surface quality.
