Bosch Compress 7000 38-2 LW Groundwater Heat Pump 38kW, 8738207483

Compress 7000 LW EHP-2
Ground source heat pump for multi-apartment buildings, public buildings, commercial and industrial facilities. The series includes eight different models with a nominal capacity ranging from 22 kW to 80 kW, but by cascading five units, it is possible to achieve a power of up to 400 kW.

Excellent efficiency
The Compress 7000 LW series uses high-quality components and the latest technologies. The result speaks for itself - all units comply with the A +++ energy efficiency class. For example, the Compress 7000 28-2 LW with a nominal capacity of 28.9 kW achieves a seasonal energy efficiency value of SCOP 5.61. In other words, it produces 5.6 times more energy in a year than it consumes.

2 compressors save energy
The 7000 LW series is designed according to an innovative tandem scheme. Each heat pump has two identical compressors that can operate independently or both at the same time. When one compressor is operating (which is 70-80% of the heating season), the cooling circuit provides favorable conditions for efficiency. In addition, by using separate compressors, the heat pump's start-up current is reduced by almost half. This allows for a smaller size of the installed protective device and, accordingly, reduces the cost of providing an electrical connection.

Injection technology
Another reason for the high efficiency of the Compress 7000 LW is the injection of the refrigerant. This is a process in which the gaseous refrigerant is injected into the middle of the compressor to cool it down and increase the mass of the compressed refrigerant. As a result, the compressor wears out less, while the heat output remains consistently high even at higher supply temperatures. The Compress 7000 LW provides a flow temperature of 68°C, providing the user with high comfort and the ability to prepare hygienic hot water without the need for an additional water heater.

Smart control
The control system supports Modbus and BACnet protocols, as well as supports smart grid functionality. By installing additional modules, it is possible to control up to ten separate heating zones. The Compress heat pump can be combined with an existing heat generator or central heating system. The interaction between the two heat sources creates a hybrid system with high efficiency - an ideal solution for modernization projects.
