Condensing units are Ecodesign-ready

BITZER_ECOSTAR_LHV7EGERMANY: Bitzer’s new LHV7E condensing unit already meets the requirements of the 2016 EU Ecodesign Directive.

Noise levels and energy consumption are said to be reduced significantly thanks to the integrated EC fan. The fans have a sound-optimised airflow and the compressor is located inside a sound-damping housing. When the cooling load is normal, the system can be operated in ECO or low-sound mode.

Efficiency is also improved by the incorporation of an optimised control, which allows the user to adjust the speed of the fans and the EcoLine Varispeed compressor at any time.

The optimised mini-channel condenser is also said to improve eco-efficiency – compared to the previous EcoStar models, the LHV7E requires a lower refrigerant charge while offering higher heat exchange.

In addition to standard field tests, the LHV7E has also undergone many other tests with a Varispeed compressor, including refrigerant injection and R407F, and proven itself across the board in low temperature applications thanks to stable operation with acceptable discharge gas temperatures even in high ambients.

The optimised Lodam controller with newly integrated Bluetooth technology is also said to have proven to be a helpful feature, ensuring technician-friendly operation of the EcoStar.

The LHV7E 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. Another new feature is that up to four EcoStar condensing units can be linked together via the Modbus. 

The LHV7E is available in six variants, four of which offer a capacity of up to 42kW. Depending on the model, it’s compatible with R134a, R404A, R507A, R407A, R407C and R407F

With its compact design, the condensing unit also fits into smaller plant rooms, while the robust housing also makes it suitable for outdoor use. The integrated winter start feature allows the compressor to be started even in winter when the ambient temperature falls below the saturated suction temperature.

The Bitzer LHV7E condensing unit comes standard with an integrated frequency inverter and filter drier. Optional features include an oil separator with check valve, oil monitoring and an additional check valve for installation in low ambient temperatures.
