Bitzer recently presented its new Ecostar condensing units, which already comply with the Ecodesign Directive for 2018, at the EuroShop trade fair.
With the Ecostar LHV5E and LHV7E, Bitzer has developed two air cooled and particularly energy efficient series of condensing units.
The new series exceeds the specifications in the EU Ecodesign Directive providing users long-term planning security.
From July 2018 the minimum efficiency performance standards (MEPS) requirements will become much more strict.
Users can choose between three models of the LHV5E and from 10 models of the larger LHV7E.
Both series of condensing units have an improved mini-channel condenser, which means they need less refrigerant charge, while at the same time being more efficient than their predecessors.
The new Ecostar condensing units also have electronically commutated fans to save electricity with the latest generation of active PFC monitoring.
Users can smoothly adjust the speed and power of the fans and of the integrated Ecoline Varispeed compressor.
In this way it is possible to operate with optimised energy requirements with a low number of switching cycles. The new condensing units also boast a reliably long useful life and low maintenance requirements.
Devices can be quickly installed on-site thanks to the control electronics being factory-wired, making them immediately ready-to-operate.
The Ecostar's integrated controller automatically adjusts the compressor speed as well as the fans to match the actual cooling load, i.e. the ambient temperature, making the overall system especially efficient.
Depending on the choice of model, the condensing units are designed for use with the refrigerants R134a, R404A, R507A, R407A, R407C and R407F, so that Bitzer can cover a wide range of applications.
Additional refrigerants with a low global warming potential (GWP), for example R448A, R449A, R450A and R513A have already been programmed into the firmware so that they are available on request.
