Air-to-water monoblock heat pump Airmax3 Hybrid Heating System 1F R290 7GT (2-9 kW) G200/B100 Gbox Sinum Lite SG-000107SL

Modern heating solution for energy-efficient and modernized homes

Airmax3 7GT (2-9 kW) heat pumps represent the third generation of air source heat pumps produced by Galmet, offering advanced technology in a complete kit ready for installation. This is the brand's first inverter heat pump utilizing the eco-friendly R290 (propane) refrigerant, which provides excellent thermodynamic properties with minimal environmental impact.

Inverter technology and operating parameters

The heart of the system is a modern inverter scroll compressor, which allows for flexible modulation of heating capacity in the range of 2-9 kW, perfectly adapting to the needs of both energy-efficient homes and older buildings with radiator installations. Combined with the R290 refrigerant, it achieves exceptional efficiency confirmed by the A+++ energy class (A7W35) and a COP coefficient of 5.0.

The reversing system allows for the combination of three functions in one device: building heating and cooling, as well as domestic hot water preparation. The device maintains a supply temperature of up to 68°C even at outdoor temperatures from -5°C to 20°C, providing heating comfort comparable to traditional boilers.

Complete installation kit and intelligent control

The kit includes a specially designed Gbox hydraulic module with a built-in three-stage flow heater with a capacity of 7 kW (2.33/4.66/7 kW), an energy-efficient electronic circulation pump, and a controller with a color touchscreen. The module supports two heating circuits and wireless room sensors, and its power supply can be provided at 230V or 400V.

The vertical SGW(S) Tower Grand tank with a capacity of 200 liters is equipped with a large spiral coil with a surface area of 2 m², an electrical heating element with a capacity of 2 kW, and double magnesium anodes to protect against corrosion. Polyurethane foam insulation minimizes heat loss, while a soft skay cover provides an aesthetic form.

The SG(B) buffer tank with a capacity of 100 liters functions as a hydraulic separator, stabilizing the system's operation and significantly extending the lifespan of the entire installation. Made of black carbon steel, it can operate with heating water or glycol at a maximum pressure of 0.3 MPa.

Ecology and user comfort

The R290 refrigerant is characterized by zero ozone depletion potential (ODP = 0) and a very low global warming potential (GWP = 3). Thanks to the monoblock design, the installation does not require F-gas certification, which significantly simplifies assembly.

The Active Defrost system ensures intelligent and efficient defrosting, while Anti-Freeze provides active protection against freezing. The Dual Silent mode guarantees extremely quiet operation - the acoustic pressure is only 40 dB, allowing for installation even in densely built-up areas.

The Sinum Lite Smart Home hub turns the kit into a smart home center, offering control via a mobile application and a web browser. It enables control of underfloor and radiator heating, cooling, ventilation, lighting, and blinds from a single application.

The device was awarded the Gold Medal at the INSTALACJE 2022 trade fair and a medal at the ENEX 2022 trade fair, and its production takes place in Poland while maintaining the highest quality standards and a manufacturer's warranty of 5 years.
