F1S InFloor convectors

F1S InFloor

F1S convectors InFloor are manufactured in 55 dimensional combinations F1S product line includes: 2 standard heights (75 and 110 mm) 4 standard widths (170, 200, 230 and 250 mm) 11 standard lengths (from 700 to 2800 mm)

InFloor F1S - basic characteristics:

  • high heating output
  • can be used as the only heat source in a heated space
  • low volume of water - quick response - energy saving
  • EC motors with low power input for safe voltage 24 V
  • quiet running fan
  • suitable for low teperature heating systems and heat pumps
  • room thermostat control with tree-stage fan speed control or the possibility of continuous fan speed control 0-10 V
  • possibility of customization - dimensions or shape modifications

F1S models come delivered with the following as standard:

  1. trench made from galvanized sheet steel, painted in black RAL 9005
    • fronts and sides of trench with break-out openings for connection to the piping and cabling
    • all visible trench components are painted in black RAL 9005
    • accessories including M8x30 set screws for trench positioning, set angle brackets for fixation of the bathtub to the floor with anchor function in concrete, rubber grommets for breakout holes and flexible stainless steel connection hoses with sealing
  2. Cu / Al heat exchanger, painted in black RAL 9005, finished with two glands with G 1/2' female thread and fitted with a venting valve
  3. tangential fan with 24 V EC motor and protective grille
  4. cover plate overlapping the connection point to the pipework
  5. chipboard covering the convector tray, fan and heat exchanger during transport and assembly

Optional extras:

  • trench made of brushed stainless steel sheet e.g. AISI 304 or AISI 316Ti or other material according to customer's request
  • speed controller, room temperature sensor, room thermostats, remote control of room thermostats
  • shut-off and control fitting, thermostatic valve, electrothermal valve actuator
  • heat exchanger sensor to prevent the fan from running at insufficient heating water temperature
  • external three-sided thermal and acoustic insulation of the whole trench against impact noise
  • coating of trench, exchanger and other components in different shade according to RAL
  • uncoated heat exchanger

Advantages of F1S Convector:

  • optimised usage of the inner trench spaces
  • optimised impellor length compared to the length of the heat exchanger
  • high heat output
  • high convector efficiency
  • low price of the convector related to 1 W of heat output
  • low electrical usage of the tangential impellor
  • low usage costs
  • quiet

F1S InFloor convector order codes:

Type   Width   Length   Height   Trench material
F1S = InFloor with a impellor - 17 = 170 mm - 070 = 700 mm - 08 = 75 mm - 01 = galvanized, standard version
    20 = 200 mm
23 = 230 mm

23 = 230 mm
34 = 340 mm
  :   11= 110 mm   11 = stainless steel, standard version
