The R290 Commercial Heat Pump System is designed for commercial heating applications that require dependable high-temperature water production and flexible capacity control.
Using R290 natural refrigerant and Dual DC Inverter technology, the system can deliver water temperatures up to 78°C while adapting heating output to changing system loads. Its cascade configuration and smart control functions make it suitable for both standalone installations and larger commercial heating projects.
With a maximum water outlet temperature of 78°C, the system can support applications where standard low-temperature heat pumps may not provide sufficient water temperature.
It is suitable for:
Commercial space heating
High-temperature hydronic systems
Domestic hot water
Heating system replacement
Large residential and commercial projects
The high-temperature capability also provides greater flexibility when connecting the heat pump to existing heating infrastructure.
The Dual DC Inverter system adjusts compressor operation according to the actual heating load.
Instead of maintaining a constant output, the system can modulate its capacity as demand changes. This helps improve system stability and reduce unnecessary operation during periods of lower heating demand.
Key benefits include:
- Precise capacity adjustment
- Stable water temperature
- Efficient part-load operation
- Reduced compressor cycling
- Flexible response to changing loads
The Commercial Series achieves ErP A+++ at 35°C and a SCOP of 4.57, supporting efficient operation in suitable low-temperature heating applications.
The inverter-driven system further helps optimize performance when heating demand varies throughout the day.
Commercial heating requirements can vary significantly between buildings and applications. The system supports cascade operation of up to 8 units, allowing multiple heat pumps to work together as a larger heating system.
This provides:
- Scalable heating capacity
- Flexible system configuration
- Better load matching
- Easier capacity expansion
- Improved operational flexibility
The built-in Wi-Fi and IoT cloud functions provide convenient access to system operation and monitoring.
These functions allow heating operation to be adjusted according to different project schedules and system requirements.
