Solareast Heat Pump Ltd. offers a reliable and efficient  R290 commercial heating and cooling heat pump system

逗号High Reliability

The BLN series commercial heat pumps from Solareast are packed with multiple operation protection, alternative cycle duty,defrosting operation, and anti-corrosion protection. These three features ensure reliable and efficient operation, even in demanding commercial environments.

The multiple operation protection feature safeguards the heat pump against voltage fluctuations, overheating, and other electrical faults, prolonging its lifespan and enhancing operational safety.

The alternative cycle duty and defrosting operation enables the heat pump to adjust its operating mode based on load requirements, ensuring optimal performance and energy efficiency.

Additionally, the anti-corrosion protection prevents damage from corrosive elements, enhancing the durability and longevity of the heat pump.


逗号Stable Operation At -25°C

The BLN series commercial heat pumps are equipped with the innovative EVI technology, enabling them to operate efficiently even in extremely low temperatures. With this feature, the BLN heat pumps can work effectively in ambient temperatures as low as -25 ºC. This makes them suitable for a wide range of commercial applications, such as hotels, hospitals, and industrial buildings, where heating is required in harsh winter conditions. The EVI technology allows the heat pump to maintain a high coefficient of performance (COP) and provide consistent heating output, ensuring optimal comfort and energy efficiency.

Whether it's heating large spaces or maintaining hot water supply, the BLN series heat pumps deliver reliable and efficient performance even in the coldest climates, making them a versatile and reliable choice for commercial heating needs.


逗号 All DC Inverter

Solareast stand out with their high efficiency for energy saving and quick start-up. These heat pumps are designed to optimize energy consumption, resulting in significant cost savings for commercial establishments. Additionally, the quick start-up feature ensures rapid operation, reducing waiting times for hot water or space heating. This not only enhances user comfort but also improves overall efficiency.

Moreover, the heat pumps are engineered to have less frequent start/stop cycles, reducing wear and tear and extending their lifespan. With their energy-saving capabilities, quick start-up, and reduced maintenance needs, the BLN series provides reliable and cost-effective heating solutions for commercial applications where efficiency and performance are critical.

逗号Water Temperature Outlet Up To 75 ºC

With two impressive features: intelligent climate curve adjustment for automatic water temperature adjustment and a higher water temperature output of up to 75 ºC.

The intelligent climate curve technology allows the heat pumps to adapt the water temperature automatically based on the surrounding conditions, optimizing both comfort and energy efficiency.

Moreover, the BLN series heat pumps are capable of delivering a higher water temperature output of up to 75 ºC, making them suitable for various commercial applications that require hot water supply at elevated temperatures. With these advanced features, the BLN series provides efficient and customizable heating solutions for commercial users, ensuring precise temperature control and reliable performance.


逗号 R290 Refrigerant,env ironment friendly

One remarkable feature of the BLN series commercial heat pumps from Solareast is their use of R290 refrigerant with a low Global Warming Potential (GWP) of 3. R290, also known as propane, is a natural refrigerant that offers exceptional environmental benefits. With a GWP of only 3, it has a significantly lower impact on climate change compared to traditional refrigerants. This makes the BLN series heat pumps not only highly efficient but also environmentally friendly.

By utilizing R290 refrigerant, Solareast demonstrates their commitment to sustainability and reducing greenhouse gas emissions. This feature ensures that the BLN series heat pumps not only provide reliable and energy-saving heating solutions but also contribute to a greener and more sustainable future.

逗号Super Silent

Solareast offer multiple silence modes, a feature highly appreciated by users seeking quiet and peaceful operation. The multiple silence modes provide users with flexible control over the sound emitted by the heat pumps. Whether it is for the comfort of customers in a hotel room or minimizing disturbance in a working environment, the BLN series heat pump allows users to choose the appropriate noise level that suits their unique needs. Moreover, the special attention given to sound reduction ensures that the heat pumps operate at a low noise level, minimizing needless disturbance and making them ideal for noise-sensitive commercial applications.
