HERE IS AN INNOVATIVE, OIL FREE, HIGHLY EFFICIENT WATER CHILLER
AXIMA REFRIGERATION FRANCE, as European leader in commercial and industrial refrigeration, is pleased to launch an innovative water chiller, so called QUANTUM, dedicated to building’s facilities and industrial refrigeration.
It can respectively be used for air conditioning systems (banks, malls,…) and industrial processes (food industries, cosmetics, metallurgy…).
QUANTUM is a modular system which includes 1 to 6 centrifugal compressors providing a cooling duty from about 300 to 1800 kW.
The centrifugal compressor is fitted with magnetic bearings – preventing from any mechanical friction and offering high sturdiness. Moreover, as it is oil free operated, the maintenance costs are drastically reduced.
Whatever the operating conditions are, and especially at partial load, QUANTUM energy consumption is lowered thanks to a speed control system. So, depending on these operating conditions, the coefficient of performance (COP) varies between 5 and 11.
The water enters the chiller at 20°C max. and is cooled down to 4°C min.
For instance : for some water entering at 12°C and cooled down to 6°C, QUANTUM 4 energy consumption is limited to 206 kW while cooling duty is 1100 kW (assuming availability of cooling water at 26°C) !
Another important benefit: while starting up QUANTUM, the required intensity is less than 5 A.
The compact design of this water chiller, linked to a low noise level, and low weight, makes it easy to be integrated within machine rooms. Number of pipes within the unit has been reduced to insure optimal tightness. R134a has been selected as refrigerant and flows through shell and tube heat exchangers (the evaporator is flooded type), allowing more convenient maintenance operations.
The compressor which is set up into QUANTUM is oil free semi-hermetic type. It fully complies with in force environment rules.
QUANTUM is easy to use thanks to a SIEMENS PLC.
It is also fitted with a GTC plug, to allow monitoring and Internet connection.
As an option, one can also connect an industrial PC, an Ethernet connection, a bus, temperature probes onto the cooling water inlet and outlet nozzles, intensity probe, leak detector, additional pressure gauges,…
