Bitzer semi-hermetic Condensing unit LH44E/2HES-1Y-40S 400V

Air-cooled condensation units with semi-hermetic compressors
The Ecodesign Directive introduced more stringent efficiency requirements for fans from 2015 and for condensation units from 2016. The new air-cooled LHE condensation units fulfil these criteria with an impressively optimised combined fan and condenser.
It has a conveyed volume range of 4 to 110 m3/h (50 Hz). The condensing units are available as a module system in several different configurations.
Standard condensing units
• With single compressor: LH32E/2KES-05(Y) to LH135E/6HE-28(Y)

Options:

• accessory pack
• additional equipment (pre-installed)
• weather protection casing
• electronic speed regulator for condenser-fans LH32E/.. to LH124E/..

• CRII: semi-variable power regulation from 100% - 10% depending on operating conditioning and refrigerant from CE2
• CM-RC01: As an option in addition to the proven semi-hermetic BITZER piston compressors, the Ecoline series (from CE4) with IQ module offers further improved compressor functions
