HCI-RANGE - heat pumps, chillers and combined systems
The Fenagy HCI-range reaches capacities from 500 kW to 6,000 kW heat per system. The systems can be used for heat pump, chiller and combined water-water operation. The entire range is designed to deliver optimal performance in accordance with customer-specific operation needs. The HCI-range is only available as water-to-water systems, thereby ensuring a small refrigerant charge.
The HCI-range uses the natural refrigerant isobutane and can reach supply temperatures up to 95°C, regardless of the return temperature.
The HCI-range is typically used for high-temperature heat pump applications, heat pumps for the energy sector (PtX, geothermal, biogas, CCSU), industrial processes, as mechanical sub-cooler and as booster in district heating systems. The systems can also be used as water-sourced heat pumps for district heating or heat networks and for normal water-cooled chiller applications.
APPLICATIONS
High-temperature heat pumps
Heat pumps for the energy sector
(PtX, geothermal, biogas, CCSU)
Industrial processes
Mechanical sub-cooler
Booster in district heating systems
Easy installation with enclosure
The HCI-range systems are always delivered in a reach-in enclosure, which is suitable for both in- and outdoor installation.
The enclosure is constantly ventilated with an EX-fan, which ensures negative pressure and maintains the right temperature in the cabinet.
The enclosure has insulated walls with sound dampening panels.
Control systems
The complete range uses a standard Siemens PLC controller, and Fenagy has developed its own PLC algorithms for the most essential functions to ensure optimal control and monitoring. Our PLC solutions can communicate with most of the platforms the customer will need to communicate with. The onboard HMI panel offers direct monitoring of the system and its operating conditions. Furthermore, our PLC solutions support several communication protocols and can integrate with the overall SCADA system.
For all systems, Fenagy aspires to minimise start-up and shutdown times, enabling the system to help balance the electrical grid in a future with an increasing demand for such functions. Last, but not least, the system can deliver high supply temperatures, and Fenagy is continuously pushing the boundaries with new functions and features in the PLC development.
