HCI-RANGE - heat pumps, chillers and combined systems
The HCI-range reaches capacities from 500 kW to 2,000 kW heat per unit and can be used for heat pump, chiller and combined water-water operation. They are designed as modular units that can be used independently or in series. The modular concept allows the units to be connected in series on the water side – up to three units can be connected, providing up to 3 or 6 MW per series. Multiple rows of connected units can also be installed, enabling us to deliver virtually unlimited capacity according to project needs.
All HCI units are designed as water-to-water systems, ensuring a low refrigerant charge. Using the natural refrigerant isobutane, HCI units 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 in data centres, heat pumps for the energy sector (CCUS, biogas, geothermal) and industrial processes, as well as a mechanical sub-cooler or as a 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.

Easy installation with a ventilated cabinet
All HCI-range systems are supplied in a reach-in cabinet for installation in a machine room. The cabinet is continuously ventilated by an EX-fan, which maintains negative pressure and ensures optimal internal temperature in accordance with EN 378. The cabinet's insulated walls are equipped with sound-dampening panels for quiet operation.
On request, we can supply solutions for outdoor installation where the HCI cabinet is installed inside a technical enclosure from the factory. The technical enclosure is a fully-approved machine room with lighting, ventilation, exhaust fan, gas detector, alarms and 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.
