RIS P • Air handling units

  • Heat recovery units
  • Counter flow
  • 420 ≤ Qv ≤ 2500 m³/h

Application

  • Ventilation of houses, offices or other heated premises (classrooms, apartments, conference rooms, etc.)

Composition

  • Frameless construction from double-skinned panels
  • Acoustic and thermal wall insulation: RIS 400–2500 P EKO 3.0 – 30/50 mm
  • RIS 400-700 P EKO 3.0 powder-coated white housing RAL 9016; RIS 1200–2500 P EKO 3.0 powder-coated grey housing RAL 7040
  • Integrated electrical heater or optional duct-based water heater/cooler
  • Low-pressure-drop filters: F7/M5
  • Hinged door with locks grants easy access to internal components
  • Separate compartment on the side of the unit grants quick access to the control board (plug-and-play)
  • Stainless steel condensate tray
  • Fitted with mounting brackets
  • Integrated anti-frost pressure switch (RIS 1200-2500 P EKO 3.0)

Characteristics

  • RIS P EKO 3.0 is a range of heat recovery units with high-efficiency counter-flow heat exchangers and low height. The units are designed for mounting under ceilings in order to save space. There are 5 sizes (airflow interval 420-2500 m3/h) with separate heaters available for different climate zones
  • RIS P EKO 3.0 units have high overall energy savings due to the highly efficient heat recovery (up to 90%), quiet and economical EC fans, effective low-pressure-drop filters, 100% motorized bypass dampers (for the 1900 and 2500 versions) and top-level of air tightness
  • Energy efficiency ensures full thermal comfort for passive houses, without an additional pre-heater at temperatures above -5°C
  • All the RIS P EKO 3.0 units are fully equipped with automatic controls. Optional external sensors for CO2 and humidity and the event planning feature will help to control automatically your climate (demand-level control)
  • RIS P EKO 3.0 units are service-friendly and are easy to mount. Filter pollution may be identified by timers or contamination controls (RIS 1200-2500 P EKO 3.0)
  • All units are supplied tested and ready to install
  • Three types of remote controllers: Flex, Stouch or Ptouch controllers; BMS connections; via PC MB-Gateway
