Compact P AIR 9

The Compact P AIR 9 has the same functions, benefits and options as the Compact P but can further be used to exploit outdoor air to heat the home.

When you install a Compact P AIR 9, your home will become self-sufficient in sustainable energy and it will no longer be necessary to use other sources of energy, such as district heating, oil or gas, to heat your home. The Compact P AIR 9 is the eco-friendly choice for anyone who wishes to exploit sustainable sources of energy to heat their homes and at the same time reap the benefits in the form of lower heating bills and a good, healthy indoor climate. 

The system is equipped with an outside air heat pump, AIR 9 Compact, which, in contrast to the system itself, is set up outside. The heat pump absorbs the energy in the outside air and coverts this energy into heat that is used to heat water in your central heating system, which is then pumped to the radiators or underfloor heating in your home.

The Compact P AIR 9 solution can reduce your heating bill by up to 50%. For each kW power used by the outside air heat pump, you get up to four times as much heat in return.

Compact P AIR 9 is also available in a version with a built-in pre-heating element – Compact Polar AIR 9. Compact Polar AIR 9 is optimum for use in cold climates.

Compact P AIR 9 has the same benefits and functions as Compact P, but also has an integrated air/water heat pump, with connection to waterborne underfloor heating or lowtemperature radiators for central heating.

The solution consists of an integrated interior section in Compact P, as well as an exterior section that is easy to connect.

AIR 9 is delivered with a reversible heat pump, which also makes the unit capable of cooling.

AIR 9 is very silent and can be placed without disturbing it surroundings. During summer, when only hot sanitary water is needed, the fan is limited, reducing the noise level. This limit occurs when the outdoor temperature exceeds 15 °C and limiting the compressors output to a maximum off 60 %. These criterias can be set individually.

Top cover

To cover the ducting over the unit, Nilan offers a top cover in white-varnished aluzinc (RAL 9016).

Solar

Extra heat exchanger of 0.7 m2 in the hot water tank, which can be connected to an approximately 3 m2 solar heating system, or other heat sources.

CO2-sensor - CTS 700 control

With a CO2-sensor installed, the ventilation speed can be pre-programmed with CTS 700 to run at a higher ventilation steps when CO2 reaches high level in the extract air. CO2-level is programmable.

Pollen filter F7

A pollen filter class F7 can be fitted in the unit. The pollen filter is fitted with the G4 plate filter.

EM-box

An EM-box allows heat recovery from the air from the range hood and thereby helps to heat the supply air. The EM-box is equipped with a steel filter which efficiently cleans the range hood air of fat particles and thereby protects the system.

 

Electrical pre-heating element (Frost protection)

An electrical pre-heating element heats up the outdoor air before it enters the unit. This avoids having to defrost the unit, resulting in a loss of power. There are
temperature sensors supplied to be fitted in the ducts.

(Integrated in the Polar version).

Electrical heating surface incl. regulation

When you fit an electrical heating surface, you can raise the fresh air temperature to the desired level at any time. The electrical heating surface is supplied ready to fit into the fresh air duct and, for easy fitting, the device is pre-fitted with all the required sensors.

 

Water heating element incl. regulation (duct mounted)

The supply temperature can always be raised to the required level using a water heating element. The water heating element is designed to be built into the duct and must be connected to the primary heating supply. Supplied with two-way adjustment valve, temperature sensor and frost thermostat.

3 levels The control function is divided into 3 levels: User / Installer / Factory with various options at each level.  +
Weekly plan There is an option for you to set your own weekly programme.  +
User option 1 This allows you to override the operating mode in the main menu via an external potential-free contact or PIR sensor.  +
User option 2 This allows you to override the operating mode in the main menu via an external potential-free contact or PIR sensor. User option 2 has a higher priority than user option 1. +
User option 2 out When user option 2 is used, at the same time an output signal is given. +
Alarms The alarm list is featuring all alarms. +
Datalog Opportunity for datalog.  
Filter monitor Filter monitor with timer (factory setting of 90 days). Adjustable to 30/90/180/360 days.  +
100% Bypass Bypassing the outdoor air reduces heat recovery, enabling the desired supply air temperature to be maintained spring, summer and autumn. +
Air quality Allows you to choose whether to switch humidity sensors and/or CO2 sensors on and off.  +/-
Humidity control Allows you to set a higher or lower ventilation step in the case of high/low air humidity.  +
CO2 control Allows you to set a higher or lower ventilation step in the case of a high/low CO2-level. -
Air exchange Allows you to select a low ventilation step in the case of low outside temperatures and air humidity. +
Night setback A possibility to set back the ventilation and temperature a night. +
Defrost function Temperature-based automatic function for defrosting the heat exchanger. +
Frostprotection In case of failing heating system, the unit is turned off to avoid further cooling with a risk of the water heating coil frost bursting. +
Temperature control Allows you to select the temperature sensor which will control the unit.
•     TExt external room temperature sensor
•     T3 EXHAUST (extract air)
-
+
Air volume Allows you to set the ventilation flow stepless from 20 to 100 %. In four steps. +
Summer/Winter operation The unit automatically changes to summer or winter operation. +
Legionella control It is possible to choose a weekday or a day during the month, where the sanitary hot water temperature reaches 65 °C, for example between 1 and 6 o´clock. +
