Functionality and design of our SPI HYBRID System
The SPI HYBRID System contains of two cooling circuits using the natural refrigerants R290 and R744. This enables us to install both R290 and CO2 units in one market making use of the advantages of each system. In the next steps we will explain the system components and usage in detail.

SPI System
At first, we install an AHT Semi Plug-in (SPI) System for the refrigeration and freezing devices. The structure and components are identical to those of the classic SPI System.
It consists of a waste heat unit & pump station, cooling & freezing units and optionally of cold room aggregates, hydraulic station, the OSSM, and a heat pump. In our example only the cooling and freezing units are installed as SPI system.

Adding the CO2 System
Adding the CO2 System
In this step, we are adding the CO2 units which are, in our example, cold room aggregates. For the setup and installation this system does not require a CO2 compressor rack and gas cooler as it is operated by a small unit which passes on the waste heat to the SPI system via a plate exchanger. Which units are running on CO2 and which are installed in the SPI system can be defined precisely to your requirements.
This allows us, to be fully flexible on the offered products and systems and creating the best possible option for your market.

Extending the CO2 units
Extending the CO2 units
It is also possible, to integrate e.g. an existing serve over counter or other CO2 components in the SPI HYBRID System. In this case, we expand the system adding a compact unit to deliver the refrigerant and moving the waste heat to the SPI System.
Whit SPI HYBRID AHT offers a system solution with great possibilities to integrate various CO2 system components – just as flexible as you need it.
