PRODUCT DATA COMPACT P - SERIES BY NILAN heat recovery heat recovery Comfort heating Comfort cooling Sanitary hot water production

THE VENTILATION AND HEATING SOLUTION OF THE FUTURE Compact P is developed for future homes. The system can be used in all types of low-energy and passive buildings, but can also ensure low energy consumption in any home or flat. The integrated AIR 9, GEO 3, GEO 6 and GEO 9 heat pumps utilise the latest compressor technology to ensure that the heat output is continuously matched to the home’s requirements. Top-class efficiency Many benefits Compact P is equipped with the latest technology, comprising a highly-efficient counterflow heat exchanger, as well as a special designed heating pump that...

ONE UNIT SEVERAL SOLUTIONS Since Compact P is module-based, it offers not just one, but several solutions. The unit can be combined with a geothermal or an outdoor air heat pump that can be fully integrated into Compact P. As either a supplementary or total heating solution, Compact P combines up to five functions: Compact P • Ventilation with heat recovery • Sanitary hot water production Compact P can ventilate up to 300 m3/h and recovers more than 100 % of the energy from the extracted air via a counter flow heat exchanger that is combined with a heat pump. The heat pump produces hot water...

COMPACT P Product description Compact P is an energy-efficient total indoor climate solution for all types of low-energy buildings, single-family homes, flats and small office areas in commercial leases with a ventilation requirement of up to 300 m3/h. Compact P recovers the energy from the extracted air using a highly efficient counter flow heat exchanger. The remaining energy that is not utilised by the counter flow heat exchanger is used by the heat pump to produce hot water, and to further heat the supply air. The heat pump has a reversible cooling circuit, which means that, in the summer,...

Time-controlled filter change alarm. Easy filter access by opening the top front panel with the help of two finger screws. Intelligent humidity control. Adapts ventilation to the home’s current humidity level. There is plenty of space to replace filters and to vacuum clean the filter space. CO2-sensor can be purchased, for further demand management. A clear, user-friendly Touch panel is included. Low-energy EC-ventilators with B-wheel, adjustable from 20 to 100%. The modern CTS 700 control runs Modbus communication. Counterflow heat exchanger in polystyrene, with a temperature efficiency ratio...

Compact P ventilates the home, ensuring a good indoor climate. While also producing hot water. Supply air Compact P is an untraditional ventilation unit that, in contrast to other ventilation units, recovers 100% of the heat in the extracted air. Via a counter flow heat exchanger, up to 95 % of the energy in the extracted air is used to heat the supply air. Discharge air The built-in heat pump uses the remaining energy to further heat the supply air, while also producing hot water. Cooling the home is the challenge of the future New homes are well-insulated and therefore easy to heat. On the...

Passive and active heat recovery Utilising the residual energy that the counterflow heat exchanger does not use, the heat pump further heats the supply air. Utilising the residual energy that the counterflow heat exchanger does not use, the heat pump produces hot water. Active cooling If heat recovery is not required, the bypass damper closes off 100% and leads the outdoor air past the heat exchanger. The heat pump has a reversible cooling circuit and can cool the supply air during hot periods. Hot water can be produced at the same time. Hot water is produced with a high efficiency (COP). This...

PLANNING DATA Capacity Capacity of standard unit as a function of qv and Pt, ext. SEL values according to EN 13141-7 are for standard units with ISO Coarse >90% (G4) filters and without heating element. SEL values comprise the unit’s total power comsumption incl. control. Conversion factor: Attention! The SEL values are measured and stated as a total value for both fans Compact P is also available in a XL-version, which can provide an air volume of 430 m3/h at 100 Pa

Temperature efficiency Temperature efficiency as a function of volume flow qv [m3/h] for unit with counterflow heat exchanger. Temperature efficiency according to EN13141-7 (2°C / 20°C). NB! The temperature efficiency, is for the heat exchanger only (without heat pump operation). Temperature efficiency Volume flow Heat output supply air Heat output Qc [W] as a function of qv [m3/h] and outdoor air temperature t21 [°C]. In accordance with EN 14511, t11=21°C (extract air) Heat output is the contribution to room heating added to the fresh air via Compact P to the supply air. The ventilation loss...
