EC A1/L2 Application Ventilation of houses, offices or other heated premises (classrooms, apartments, conference rooms, etc.) Description 3. 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 42-25 m 3 /h) with separate heaters available for different climate zones. 3. units have high overall energy savings due to the highly efficient heat recovery (up to 9%), quiet and economical EC fans, effective low-pressure-drop filters, % motorized bypass dampers (for the 19 and 25 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 3. units are fully equipped with automatic controls. Optional external sensors for CO 2 and humidity and the event planning feature will help to control automatically your climate (demand-level control). 3. units are service-friendly and are easy to mount. Filter pollution may be identified by timers or contamination controls (RIS 1-25 P EKO 3.). All units are supplied tested and ready to install. Remote control Features Construction Three remote control options are available: 1. Flex, Stouch or Ptouch remote controllers. 2. Building management system connections. 3. Remote control via PC MB-Gateway. Ideal for ceiling installations. Ready for Passive House technology: high efficiency. Easy and quick mounting. Water/electrical heating options. Fully integrated plug-and-play control system. Frameless construction from double-skinned panels. Acoustic and thermal wall insulation: RIS 4 25 P EKO 3. 3/5 mm. RIS 4-7 P EKO 3. powder-coated white housing RAL 916; RIS 1 25 P EKO 3. powder-coated grey housing RAL 74. 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 1-25 P EKO 3.). RIS 4 P E.9 EKO 3.
