C-RANGE - chillers
The chillers in the Fenagy C-range are COâ‚‚ DX chillers, which reach cooling capacities from 500 kW to 2,600 kW per rack. The chillers are equipped with plate heat exchanger evaporators on the compressor frame, and they are designed to deliver optimal performance in accordance with customer-specific operation needs.
The entire C-range is available with both water- and air-cooled gas coolers. The chillers use the natural refrigerant COâ‚‚, which is ideal for applications such as the food industry, industrial processes, data centres, logistics centres, offices, hospitals and HVAC in general.

Easy installation with a FENhouse
All chillers in the C-range can be delivered in a FENhouse – a factory-built, turnkey concept where the chiller is installed in a sound-insulated enclosure designed as a fully approved machine room, complete with lighting, ventilation and CO₂ alarm.
The benefits are numerous. FENhouse arrives ready for connections, making on-site installation ultra-fast, and its compact design saves space. As a new building is not needed, the authority approval process is also shorter, and the overall cost of the installation is reduced.
FENhouse is usually delivered with a self-supporting concrete foundation, so only a levelled sand pad is needed on site for installation. It is flexible by design and can be delivered with extra space for an electrical supply panel, pumps, valves on the water circuit, etc. and is available in various designs, ensuring aesthetics are always prioritised.
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. The onboard HMI panel offers direct monitoring of the system and its operating conditions. Our PLC solutions are compatible with most customer platforms, support several communication protocols and can integrate with the overall SCADA system.
If the overall installation consists of multiple units, a master controller – FENmaster – is installed to coordinate operation between them. FENmaster offers a wide range of functions and can, among other things, handle grid balancing services and the grouping of multiple heat pumps, chillers and electric boilers.
All Fenagy systems are built with cybersecurity as a cornerstone. Among other measures, the systems are protected by network segmentation and firewalls, ensuring that each heat pump, chiller or electric boiler is always separated from other devices on the network and protected against unauthorised access, both inbound and outbound.
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.
