Trench heaters - PK

Licon PK convectors are intended for embedding in floors, especially in places prohibiting installation of higher radiators, e.g. in front of french windows, winter garden entries, hall entrances, exits etc., in public buildings (shops, administrative buildings etc.), as well as in residential houses. Various colored designs of the floor grids are making convectors suitable for any interior.

 Convector breakdown

Optional version

Basic - zinc galvanised steel case, exchanger without any surface finish, no frame.
Exclusive – black coated zinc galvanised steel (identical with the design type Economic), black coated heat exchanger
InPool – the case design in stainless steel AISI 304, unpainted exchanger (only for dry environment)
Inox – the case design in stainless steel AISI 316, unpainted exchanger (only for dry environment)

Standard delivery contains

 version Economic – black coated zinc galvanised steel case
  • unpainted heat exchanger with low water content, air vent and uniquely shaped lamellas for higher heat output
  • anodized Al frame, U profile, in colour of natural aluminium
  • fixing anchors to fix the case to the floor
  • a pair of flexible stainless steel hoses for easy connection
  • chipboard cover protecting the exchanger against dust and dirt on the building site
  • 25 mm height adjustment screws to compensate for the floor asperity
  • mounting instructions
  • the set is packed in a strong and durable packaging

Optional specification

  •  pool design PKB are standard designed with a drain hole include mounting instructions PKB

  • colour of the anodized Al frame – natural aluminium, light and dark bronze in the F profile or light or dark bronze for U profile

  • lockable screwing thermostatic valve and thermostatic shut off valve head 

  • cover plate with increased rigidity

 

Aluminium frame profiles

Standard design – U frame

U RÁMEČEK                                    U rámeček

Standard PK design contains silver U profile. Profile colour is equal with grid colour, for other colours.

Selectable version – F frame

F RÁMEČEK                  F rámeček

When the selectable frame F is ordered, it is attached separately to convector (not installed on convector). Frame colours are identical with aluminium grid colours.

Pertl - Version Basic – without frame                                                 

Pertl         Pertl

Convectors installation

Connecting the floor convectors Licon PK

Cases' types according to water inlets' location and lowering of faces for batch assembly.

Lowering of the cases' faces is used where it is not desirable to see the connections between the convectors (long rows of convectors, i.e. administative buildings, hotels etc.). When ordering the walkable grid it is necessary to mention that it is the PM, which will be used for the convector with the lowered face.

Note: The PKB convectors' individual cases cannot be mutually interconnected. These are made only in P0 design.

Building recommendation Several general principles must be fulfilled for proper function of the convector.

  • To interconnect the exchanger and the distributing pipeline, the standard stainless-steel hoses with stainless-steel jacketing must be used (unless recommended otherwise) which always form a part of the delivery. In practice they provide a better access under the heat exchanger without having to dismantle the heating system, e.g. during cleaning.
  • ​A correctly installed convector is mounted horizontally and the top edges of the convector case are not warped or deflected to ensure proper functioning of the walk-on grid and allows venting of the heat exchanger.
  •  Correctly installed convector's decorative frame at the floor covering is within the margin of + 2 mm.
  • We recommend to keep the cover board in its place for the full duration of the building work to prevent dirt getting inside the convector. The standard board supplied is not walkable. A higher load bearing capacity board can be ordered.
  • The height adjustment screws are only used for horizontal levelling of the convector case.
  • During concreting the convector must be fixed to the floor with the use of fixing anchors screws that will prevent vertical shifting of the convector during subsequent pouring of concrete. The convector can be vertically loaded during concrete pouring. During concreting the convector must be strutted to prevent deformation of the case. When using other casting material (e.g. anhydride) seal thoroughly all passages into the convector to prevent it from flooding.
  • Convectors with stainless steel case, designed for humid environments and identified as PKB have a standard built-in water drainage. It must be interconnected during the installation with a pipe with secured slope to drain the waste water. We recommend to fit the drain with the odour trap.
  • For further versions for PK built-in  (Possibility to imbed in floors according to floor types).
