Airmax 3rd generation is the result of many years of experience of Galmet's research and development department and continuous pursuit of perfection. The latest generation of heat pumps are inverter air-source heat pumps with ecological and efficient R290 refrigerant designed for new and renovated buildings. These are two devices Airmax³ 7GT (2-9kW), Airmax³ 12GT (3-15kW) allowing flexible modulation of their heating power and adaptation to the heating needs of practically any home. Both energy-efficient, newly built ones and older, modernized buildings with radiator installations. Airmax³ guarantees "green" and cheap heat in our homes. Thanks to its versatility, Airmax³ works perfectly both in single-family houses and in larger facilities such as multi-family buildings, offices or industrial halls.

Comfort, ecology, maintenance-free operation and lowest operating costs - this is the best summary of the advantages of Airmax³ – the latest heat pumps from Polish manufacturer Galmet.

Airmax³ impresses not only with its appearance, but also with advanced technology and exceptional efficiency confirmed by energy class A+++, thanks to which it reduces heating costs. This is a combination of the highest efficiency of advanced inverter-controlled compressors and ecological R290 refrigerant with excellent thermodynamic properties. Heating, cooling the house and domestic hot water heating is possible thanks to free energy from renewable sources. The highest COP coefficient of 5.2 (for the 12GT model at A7W35) testifies to the high efficiency of the device.

Cooling function, intuitive application with full range of functions for user and service technician, large readable control panel with high-resolution color screen, support for wireless room sensors, complete set of sensors, control of two heating circuits and other heat sources and ventilation system or cooperation with Smart Home intelligent house system are functions and options prepared for the user as standard.

All this is available in the form of complete ready-to-install sets for quick installation.

Exceptional technology and highest efficiency

• The heating power of the Airmax³ heat pump can be intelligently adapted to demand both in the case of energy-efficient homes and the most demanding modernized ones.
• The reverse system used in Airmax 3rd generation combines 3 functions in 1 device – heating, cooling the building and domestic hot water heating.
• High COP coefficient of 5.2 (12GT model for A7W35) is record efficiency for air-source heat pumps.
• Airmax³ reaches high water temperatures on the supply close to 70°C (up to 68°C for air temp. from -5°C to 20°C).
• Ecological, natural R290 refrigerant has excellent thermodynamic properties. Combined with an inverter compressor, it ensures exceptional efficiency of the heat pump confirmed by energy class A+++.
• Achieved efficiency is up to 21% higher compared to the previous generation.
• Hermetically sealed heat pump system - monoblock type – combined with a special hydraulic module ensures quick installation of Airmax³ heat pump.
• Winner of the most prestigious awards: Gold Medal of INSTALACJE 2022 fair and medal of ENEX 2022 fair.
• Developed and manufactured by Galmet in Poland.

Proven construction

• Efficient Emerson Copeland Scroll inverter spiral compressor is the most efficient solutions on the market! Allowing flexible modulation of heat pump heating power even in the range from 2 to 9 kW (Airmax³ 7GT) or from 3 to 15kW (Airmax³ 12GT) and adapt them to almost all installations - both energy-efficient, in new buildings, and older, modernized e.g. with radiator installations. Airmax³ heat pump compressor provides better operating parameters – higher operating temp. – better envelope – than even compressors with EVI on R410!
• 23% lower outdoor unit (Airmax³ 12GT vs Airmax² 12GT) – allows easy installation, even under a window.
• Timeless classic design and natural shapes and colors of the outdoor unit work very well in any space.
• Durable housing resistant to atmospheric factors was made of aluminum and plastic.
• Airmax³ heat pump was tested in a cooling chamber, in extreme climatic conditions already at the prototype stage.
• Efficient defrosting of the new Airmax outdoor unit is taken care of by the intelligent Active Defrost system.
• Anti-Freeze - active protection against freezing has also been introduced in Airmax³.

Extremely quiet

Engineers from the hybrid heating systems and heat pumps R&D department at Galmet have also ensured the best acoustic properties of the latest design. The new generation Airmax is 13% "quieter" than its predecessor (sound power Airmax³ 12GT vs Airmax² 12GT).

• The new Galmet heat pump uses double silencing - Dual Silent mode.
• Very quiet operation enables installation in dense housing development.
• Exceptionally quiet fan operation is thanks to their aerodynamic shapes.
• Sound pressure is only 40 dB - Airmax³ 7GT.

Ecological refrigerant

Advanced technology and high efficiency of Airmax 3rd generation are the result of combining state-of-the-art inverter compressors with excellent thermodynamic properties of ecological R290 refrigerant, so-called propane.

• High efficiency of Airmax³ heat pump is achieved with a smaller amount of refrigerant.
• Natural R290 refrigerant allows achieving very high heat pump operating parameters and high efficiency even at low outdoor temperatures.
• R290 refrigerant does not negatively affect the ozone layer. It has the lowest ODP (Ozone Depletion Potential) = 0.
• Ecological R290 is safe for the environment. Propane has the lowest impact on the greenhouse effect among refrigerants used in heat pumps. GWP (Global Warming Potential) = 3.
• The benefit for both installer and user is also no need to register the device in the CRO database - Central Register of Operators, as is the case with older refrigerants.

Easy and quick installation

Installation and operation of the Airmax³ heat pump are intuitive and simple. They also do not require f-gas qualifications. Specially for new inverter heat pumps, Galmet has developed special Gbox and Onebox hydraulic modules. They contain practically all necessary boiler room elements in one module. Additionally, Onebox is a so-called hydraulic cabinet, i.e. it has been integrated with a domestic hot water tank. All hydraulic connections, sensors and controls are routed to the hydraulic module. Only communication cable and power supply are routed to the outdoor unit. This significantly simplifies installation and service. Gbox and Onebox are universal and adapted to all Airmax³ heat pumps, they can also have both single and three-phase power supply.

• Convenient installation is enabled by the internal Gbox hydraulic module designed for Airmax³ heat pumps. Maximum installation simplification is ensured by using the Onebox hydraulic cabinet.
• One of many advantages for the installer is the first startup configurator – Step by Step and special installer menu.
• Configuration of Gbox module and Onebox hydraulic cabinet enables handling of two heating circuits and wireless room sensors.
• Airmax³ air-source heat pump can be automatically controlled based on heating curve, constant set temperature or operating schedule.
• Among many functions available for user and installer, important are also: control of circulation pump and DHW tank heater, heating schedule: buffer, DHW tank, heating circuits.
• Safe DHW tank disinfection is taken care of by the Anti-legionella function.
• Connection of all installation elements, central heating buffer, DHW tank, additional heating circuits etc. is enabled by a complete set of sensors.
• Convenient room temperature control is enabled by wireless room sensor, delivered as standard. It serves as a room thermostat.
• Complete control of room temperatures and heat pump operating parameters is possible via app or through web browser – internet module as standard.
• Heat pumps are offered in single and three-phase sets (230V - Airmax³ 7GT) or (400V - Airmax³ 12GT).
• Additional protection of heat pump operation in case of power supply interruptions is enabled by using UPS, with which the heat pump can cooperate.
• Airmax³ can cooperate with Smart Home System e.g. Sinum.
