NULITE FR-BG wall-mounted fan coils are designed for hydronic heating and cooling systems. The unit resembles a wall-mounted split-system indoor section, but instead of a dedicated outdoor compressor it uses chilled or heated water supplied by a central chiller, heat pump, or boiler plant.
Three models for small and medium rooms
The range includes FR68BG, FR85BG, and FR102BG. At high fan speed, cooling capacity is 3.6 / 4.5 / 5.4 kW and heating capacity is 5.4 / 6.75 / 8.1 kW. Three fan speeds provide 360–1020 m³/h airflow and allow output to follow the current room load.
The brochure lists 7/12 °C chilled-water and 65/60 °C hot-water conditions. Water flow is 0.6–0.9 m³/h, pressure drop is 25–35 kPa, and maximum working pressure is 2 MPa.

Benefits of wall mounting
- installation without a suspended ceiling or floor casing;
- a familiar indoor-unit format for occupants;
- direct access to the filter and service areas;
- three fan speeds and remote control;
- connection to the building's central hydronic system.
Applications
- hotel rooms, serviced apartments, and small offices;
- private rooms, meeting rooms, shops, and salons;
- homes served by a heat pump or chiller;
- retrofit spaces where a ceiling cassette cannot be installed;
- zones requiring individual temperature control.
Design and installation
Design must provide insulated water piping, balancing valves, reliable condensate drainage, and a 220 V electrical supply. The position should ensure unobstructed air distribution and practical service access.
Capacity depends on entering water and air temperatures, water flow, and fan speed. Final selection must be based on calculated room load and hydronic-system conditions.
