Characteristic curve

WS 160 Flat KET - Characteristic curve

The figures shown indicate the preset ventilation levels ("factory settings").

1 = 60 m³/h, reduced ventilation (RV)

2 = 90 m³/h, nominal ventilation (NV)

3 = 120 m³/h, intensive ventilation (IV)

I = Interval or "humidity protection operation" depending on RV

Individual settings available:

RV = 40 m³/h - 160 m³/h

NV = 40 m³/h - 160 m³/h

IV = 40 m³/h - 160 m³/h

Essential condition: RV < NV < IV !

Product description

Features

  • Centralised ventilation unit with heat recovery for comfort ventilation.
  • The WS 160 Flat… range of units is characterised by its compact and very flat design. The total height of just 23 cm makes space-saving installation possible in suspended ceilings.
  • The highly efficient enthalpy heat exchanger fitted as standard means there is no need for a condensate drain. The installer is therefore free to select the unit's position on any ceiling, wall or inclined surface. Other benefits of the enthalpy heat exchanger with intelligent humidity control include humidity recovery and the ideal room climate, even in winter.
  • The housing consists of expanded polypropylene (EPP) with thermal and sound insulation. The housing's EPP cover is covered with sheet steel for enhanced sound insulation.
  • Colour black/white aluminium
  • The flat units are very quiet, energy-efficient and hold an A-rating label in accordance with the ErP Directive. The fans with constant volumetric flow cover a volumetric flow range of 40 to 160 m³/h.
  • The two supply air connections (fitted as standard) allow the supply air lines to be configured without crossing one another. There is therefore no need for unit variants in left-hand and right-hand versions.
  • As standard, the unit has an F7 filter in the outside air and a G4 filter in the exhaust air. As an option, a G4 filter can also be retrofitted in the outside air. This filter cascade greatly extends the service life of the F7 filter.
  • The controller is able to control a large number of external components, such as brine pump, external room heating or shutter for air/earth heat exchanger, and to extend the scope of the ventilation concept.
  • DIBT approval.
  • PH certification.
  • KBZET variant: The use of the motorised zone shutter and needs-based zone regulation allows the supply air rooms to be split into 2 zones. The relevant splitting of the volumetric flows over the 2 zones can be stored in the time programme or regulated by corresponding air quality sensors in the zones.
  • BET, KBET, KBZET variants: The integrated bypass shutter (100 % bypass) with needs-based bypass control makes a continuously variable bypass control possible. Depending on temperature differences and user settings the room air can be cooled in an optimum manner without draughts.
  • KET, KBET, KBZET variants: The performance-controlled electrical preheating register is regulated depending on various parameters recorded in the unit. The result is an efficient and energy-saving regulation strategy. Ventilation with a heat register therefore does not compromise on comfort even at low outside air temperatures.

  • Integrated excess humidity avoidance function.
  • Continuously variable needs-based adaptation of air volumes.
  • Multi-function contact for controlling EW brine earth heat exchanger (uncontrolled pump), operating and fault display, preheating and postheating register, shutters.
  • Can be extended with other PCBs.

ModBus

  • Integrated MODBUS interface enables integration in the building control technology.

EnOcean

  • Optional EnOcean plug-in module E-SM for integrating the ventilation unit into "EnOcean world" "www.enocean-alliance.org"

  • Optional KNX plug-in module K-SM allows for connection to building control technology, "www.knx.org".

Heat exchanger

  • Washable anti-microbial enthalpy heat exchanger made from plastic (PS).

Frost protection

  • Prevents the heat exchanger from freezing up at low temperatures.
  • For "K" unit models, using integrated, demand-controlled, electrical PTC preheating register.
  • For "non-K" unit models, by switching off the supply air fan.

Energy-efficient fans

  • 2 radial direct current fans, curved to the front in the outside air / outgoing air.
  • 4 ventilation levels can be adjusted continuously between 40.. 160 m³/h.

Mounting information

  • Easy, very time-saving installation.
  • Housing cover is easy to remove using guide pin and safety screw.
  • Provide sound absorbers on the inlet and outlet sides.

Electrical connection

  • Ready for service.
  • Prepared for assembly-friendly connection of sensors.
  • Extendible, functional electronics box allows optional additional circuit boards (ZP 1 and ZP 2) to be fitted with ease.

Condensation drain

  • Not required.
