Industrial Machine Capable of Both
Compression and Expansion

Best in Class Performance

Highly Efficient

Achieving a 10:1 compression ratio in a single stage, the D430 enables superior performance in applications that previously required multiple stages, streamlining operations and enhancing process efficiency.

Wide Operating Range

The D430 operates effectively across a broad range of temperatures and pressures. Its advanced design enables supercritical cycles with CO₂ as the working fluid in high-temperature heat pump applications. Expanding operational boundaries where conventional compressors fall short.

Two Modes of Operation

The D430 features the ability to seamlessly switch between compression and expansion modes based on operational requirements. Using one machine to perform both functions in a heat pump application reduces overall system cost, enabling precise adjustments to meet specific application demands.

Modular Construction

Our modular design approach offers significant advantages, including lower costs and enhanced scalability. By utilizing identical cylinders in our systems, we achieve economies of scale during manufacturing, resulting in cost savings that can be passed on to our customers. This means that businesses can benefit from reduced initial investments while maintaining high-quality performance.

Additionally, the modular design allows for flexible system configurations. Machines can be easily stacked on a common shaft or combined to adapt to changing operational requirements. This adaptability means that your setup can grow and evolve alongside your process, enabling quick adjustments to capacity without significant disruptions or investments.

These features make our modular systems an ideal choice for industries seeking to maximise performance while effectively managing costs and responding to dynamic market demands.

Our architecture uses discrete modules by design, simplifying maintenance procedures. Each module can be individually serviced or replaced, allowing for quick interventions to minimise downtime and keep your operations running smoothly.

As your demands evolve over time, our discrete modules provide the flexibility to scale up capacity efficiently - without the need to replace the entire machine. Users can easily add or upgrade modules to meet increased thermal requirements, ensuring that operations remain efficient and effective as needs change.

Hot, Cold, or Anywhere In Between

The D430 is efficient at all temperatures when working as either a compressor or expander unlocking higher COP in high temperature heat pump applications.

Very high temperature heat pump applications where the return temperature of the sink stays high have considerable energy remaining in the gas before its expansion. Throttling this gas impacts the coefficient of performance (COP) of the heat pump too much for the solution be viable.

By replacing the throttling device in a heat pump with an expander machine, it is possible to recover large amounts of energy from the return gas stream and improve COP.

There are very few options for subcritical heat pumps for temperatures higher than 120°C. Transcritical and supercritical cycles are part of the solution for very-high temperature heat pumps.

Designed from the ground up for high operating pressures and extreme temperature lift, SynchroStor’s machine is uniquely positioned to provide best in class performance and the most cost effective solution to enable high-COP high-temperature heat pumps to help electrify industrial heat applications.

Flexible Compatibility

The D430 is compatible with most synthetic and natural refrigerants, enabling compliance with environmental regulations while meeting the demands of your process

When considering refrigerants, the environmental impact of leaks is a critical factor. Many traditional refrigerants have a high global warming potential (GWP) and contribute significantly to environmental degradation. Additionally, stricter regulations surrounding these substances have made compliance increasingly challenging for businesses.

In contrast, transitioning to argon, nitrogen, and CO₂ offers significant advantages. These refrigerants possess lower environmental impacts, with CO₂ being a naturally occurring gas that is safe and non-toxic. By opting for these alternatives, businesses can reduce their carbon footprint while adhering to evolving regulatory requirements.

Precisely Controlled

Our machine is equipped with a robust control system powered by six Field-Programmable Gate Arrays (FPGAs) per machine, ensuring precision, speed, and reliability. These FPGAs work in tandem to continuously monitor and adjust performance parameters, allowing for real-time adaptability to changing operational conditions.

The use of multiple FPGAs provides several layers of redundancy, enhancing system reliability and minimizing the risk of downtime. This design ensures that critical functions remain operational even in the unlikely event of a component failure, providing consistent and dependable performance.
