SEMI-HERMETIC RECIPROCATING COMPRESSOR MULTIPLE COMPRESSORS UNIT WITH LEADING INVERTER COMPRESSOR ORIGINAL MANUFACTURED EQUIPMENT

PRODUCTS SPECIFICATIONS In a world where energy efficiency and sustainability are key factors for the user of any kind of refrigeration projects, adjustability becomes an additional driving force for the design of the ipac range of units. The high adjustability is required especially to follow adequately the variation of the refrigeration load along the whole running time of the system. The integration of the inverter technology through the use of the VARISPEED compressor by BITZER, allows the required modulation and adaptation that any designer is looking for. This gives the potential to lift the evaporating temperature and stabilizes fluctuation in condensing pressure to reduce the energy consumption. The ipac, in the 2, 3 and 4 compressors configurations, will offer a compact and plug & play solution to be fit into any refrigeration applications where otherwise a multiple condensing unit installation will be required. The ipac range is a further identification of the basic phylosophy of the Added Value Products by BITZER. It incorporates all the high quality features of the well known and qualified MultiPacs semi-hermetic reciprocating compressor racks and at the same time it includes additional features characteristics of this new technology. FEATURES VARISPEED compressor by BITZER with suction gas cooled inverter, to provide maximum flexibility and efficiency also at part load.conditions Standard electrical board with customized controller that will simplify the installation of the unit. Extremely easy access to compressors and all replaceable parts fitted on the unit. Flexible eliminator and electronic oil level control on each compressor for maximum reliability. ipac racks nomenclature is reported here below, with clear similarities to MultiPac designation: // 2 Identification for ipac unit Index for the frame configuration Code for the number of compressor installed on the rack Identifier for Medium or Low temperature application Code to identify the VARISPEED compressor model Identification of the standard compressor model
