Energy-Efficient Condensing Unit
BITZER, Flowery Branch, Fla., presented the new LHV7E, a cutting-edge condensing unit that features low noise and already fulfills the requirements of the 2016 EU Ecodesign Directive.
The ECOSTAR LHV7E’s optimised control allows users to adjust the speed of the fans and the ECOLINE VARISPEED compressor at any time for more energy-efficient operation. The optimized mini-channel condenser also improves eco-efficiency, requiring a lower refrigerant charge while offering higher heat exchange.
The LHV7E features low noise EC fans with sound-optimized airflow. Plus, the compressor is located inside a sound-damping housing. This means that when the cooling load is normal, the system can be operated in ECO or low-sound mode.
The optimized Lodam controller with newly integrated Bluetooth technology ensures technician-friendly operation and works seamlessly at a distance of 30 meters away. Plus, the condensing unit can be controlled and serviced remotely via an Ethernet connection for networks or the Internet, Modbus RTU and Bluetooth access using BITZER’s BEST software. There’s also a display for operation, which comes integrated into the controller housing and offers optimized menu access. The BEST software or an optional retrofit display provides users with full access to all the menu options.
Up to four ECOSTAR condensing units can be linked together via the Modbus. Together, the condensing units form an ECOSTAR control network, and in optimized interaction, control the temperature of a cold storage unit without having to be connected in the refrigerant circuit.
The control electronics are fully wired in the factory and come ready for operation, facilitating fast installation of the condensing unit on-site. To simplify maintenance, each of the two casing parts can be opened with a captive screw, and the terminal box, the filter drier, the sight glasses and the oil separator can be accessed in no time from the outside.
The ECOSTAR LHV7E is available in six variants, and is compatible with the refrigerants R134a, R404A, R507A, R407A, R407C and R407F.
