GreenMaster-C
Supply and exhaust air units (Heat recovery unit with heat exchanger)
GreenMaster-C-F and GreenMaster-C-T are two different types of air handling units used to manage indoor air quality. Both of these units are designed to be energy-efficient and can be used for air recovery, heating, or cooling.
GreenMaster-C-F is an exhaust air unit designed to remove polluted/dirty air from a building while recovering some of the heat from the extracted air. This is done by the unit taking in the dirty air and allowing it to pass through a filter to remove particles and other pollutants. After that, the air passes through a cooling coil, where heat is transferred to a heat pump. The cooling coil is filled with a liquid mixture, usually ethanol/ethylene glycol or pure glycol, which acts as a coolant or heat transfer fluid. After the heat is transferred to the heat pump, the extracted air is released from the building.
GreenMaster-C-T, on the other hand, is a supply air unit that takes in fresh outdoor air and treats it to create a healthy and comfortable indoor environment. This can be achieved by the unit using various coils, configured to recover, heat, or cool the air. For example, a recovery coil can be used to recover heat from the outgoing air and transfer it to the incoming fresh air. A heating coil can be used to heat the air during cold winter months, while a cooling coil can be used to cool the air during hot summer months.
Both of these units are highly valuable for improving indoor air quality and can help reduce energy costs. By using these units, you can also reduce the need for traditional heating and cooling systems, which can result in significant energy cost savings. Regardless of the type of unit you choose to use, it's important to select one that is properly sized for the building or space in which it will be used to ensure it operates optimally and provides the desired indoor environment.
Flow diagram, GreenMaster-C-F
GreenMaster-C-F is commonly used in properties with existing exhaust fans that need to be replaced, either due to age or new energy requirements. GreenMaster-C-F can be delivered with or without a bypass for fire safety.
Flow diagram, GreenMaster-C-T
GreenMaster-C-T is typically used in parts of properties that require clean supply air ventilation, either as standalone units or as part of a coil exchange system. Read more about combination/coil exchange systems below. Some installation environments require completely separate supply and exhaust air units, such as heavier industries or large kitchens. In such installations, GreenMaster-C-T fits well, either as part of a system or as standalone ventilation units.
Flow diagram with heat recovery coils
GreenMaster-C-T and GreenMaster-C-F can be used in a combined solution with heat recovery coils. In the GreenMaster Application AHU Selection Software, it is possible to calculate two units for combined installation. Below is a typical example of an installation with coil heat exchangers, where the customer uses both a GreenMaster-C-T and a GreenMaster-C-F unit.
Choosing size and type
The green field below represents the recommended airflow range for optimal energy efficiency, while the blue field represents a higher airflow level that can be selected for increased performance. The yellow area is intended for applications that require high airflow and where air resistance is higher, such as when using an external heat exchanger or similar.
It's important to note that the end of the green range is approximately 1.5 m/s above the built-in battery, the end of the blue range is 2.0 m/s, and the end of the yellow range is 4.0 m/s. These speeds are relevant for selecting the GreenMaster size and help optimize energy efficiency.

GreenMaster-C-F + NIBE Heat Pump
GreenMaster-C-F Exhaust Air Units are designed to be used in a complete system together with a separate heat pump from NIBE. The model is designed in partnership with NIBE Climate Solutions and offers the possibility to connect a NIBE heat pump to harness the energy from the exhaust air in the property.
A supply air unit takes in air from the outside and heats it to the desired temperature before it continues into the building. An exhaust air unit removes air from the indoor environment and cools it down (while heating the unit's liquid system) by extracting heat energy from the air before it is released into the surroundings. Both types of units can be energy-efficient and contribute to a comfortable indoor environment.
By connecting a NIBE heat pump to the GreenMaster-C-F, you can utilize exhaust air energy and thereby reduce energy consumption and heating costs for the building. This is an environmentally friendly solution that can help reduce climate impact and save energy.
