AQUARIUS R134
a
Water-cooled chillers and heat pumps with R134a equipped
plus
semi-hermetic twin screw compressors. Cooling capacity 449 - 1594 kW.
Class A energy efficiency on all models, refrigerant R134a equipped screw compressors, an advanced evaporator and sophisticated microprocessor all combine to make Aquarius plus the choice solution for the most discerning industrial user.
ENERGY EFFICIENCY CLASS A HIGH EFFICIENCY EXCHANGERS
The high energy efficiency levels offered by Aquarius plus have been achieved thanks to meticulous design and accurate selection of sophisticated components aimed at reducing operating costs. All models feature “Class A” energy efficiency, i.e. they offer EER values in excess of 5.05 in compliance with EECCAC standards. Continuous compressor capacity control, together with the use of up to 2 compressors in 2 independent circuits and electronic thermostatic valves, offer excellent partial load energy efficiency levels. The direct expansion shell-and-tube evaporators and condensers, optimised for R134a, are amongst the most technologically advanced on the market. Thanks to their construction, and the facility for periodic maintenance, they provide stable and reliable operation in even the harshest industrial applications. All evaporators are protected from freezing by means of the microprocessor’s antifreeze function and a differential pressure switch.
R134a ENVIRONMENTALLY FRIENDLY REFRIGERANT PERFECT TEMPERATURE CONTROL
Aquarius plus features R134a, a chlorine-free, zero ozone depletion potential (ODP) refrigerant with significant environmental benefits. R134a’s reduced operating pressures and temperatures ensure high compression levels with reduced electrical power consumptions. Continuous capacity control combined with the electronic thermostatic valves allow perfect control of the cooling capacity output and hence the water outlet temperature, this being a fundamental requirement in the precision cooling of industrial processes.
HIGH TECHNOLOGY SUPPLIED AS STANDARD VERSIONS
The electronic thermostatic valves, supplied as standard on almost all models, control the refrigerant flow by means of an actuator on the basis of the pressure and temperature values measured by sensors in the refrigerant circuit. The thermostatic valves ensure unparalleled cooling capacity precision whilst simultaneously extending the operating limits of the units. Thanks to these features Aquarius N - standard;
SSN - super silent.•• plus ensures highest energy efficiency levels.
