The next level of energy efficiency and flexibility
Industrial cooling technologies evolve at a high pace, so to keep up with the demand of being more and more process centred and adaptive to increasingly variable production conditions. Flexcool was developed to cope with those stringent conditions of operation and to deliver the highest accuracy of control, flexibility of duty and efficiency of energy utilization. Aquatech’s newly introduced range of thermochiller of the DigitempEvo series, along with the new line of Aryacool dry cooler units, are the main elements of the Flexcool solution and represent the state of the art in the design of modern cooling equipment and controls.
Model CA INVERTER driven SCREW compressor Cooling capacity: 167 to 410 kW
The Ecosmart Inverter driven chillers provide low temperature water assuring the highest energy efficient functioning. INVERTER TECHNOLOGY works on the principle of variable compressor motor speed; an electrical signal is given to the compressor motor to adjust the screw speed according to the thermal load. If the thermal load is high the compressor runs faster developing a higher refrigerant flow rate and accordingly increasing the cooling power; on the contrary, the inverter reduces the refrigerant flow rate reducing the cooling power supplied consequently.
Benefits: ● High efficiency: highest EER in any working condition (partial loads) ● Inverter driven screw compressor: stepless continuous modulation from 25% to 100%. ● Inverter driven fans: air flow continuous adjustment ● Internal pump inverter driven: to have stable values of pressure of water process in any working condition. ● Oversized condensers evaporators: in order to have the best efficiency of ● EEV electronic expansion valve to reach the high est water temperature stability (+/- 0.4°C in the evaporator outlet) ● Extended compressor life: no inrush current ● Lower friction ● Safe functioning: differential pressure switches, oil flow switches, water flow switches ● Simplified installation(indoor or outdoor), with facilitated and quick startup operations. ● Eco-compatible:green refrigerant R134a. ● Low noise operation level
DigitempEvo is the new flexible solution developed for industrial processes of heating and/or cooling. It integrates both temperature control and free-cooling functions, providing accurate water temperature, pressure and flow rate to every single circuit. The traditional centralized cooling system concept (chiller + TCU) is replaced by the newly introduced Flexcool solution, with one DigitempEvo dedicated to each user coupled with outdoors free cooling capabilities. State of the art design and technical characteristics make DigitempEvo highly performing and flexible to each situation.
• Integral free-cooling • Digital scroll compressor • Braised plate evaporator and condenser • Medium and high pressure pumps • Single or double circuit with independent temperatures
• Flexible operation providing water from 5°C to 90°C to each single circuit (in the dual pump configuration the unit controls the process allowing two different working temperatures) • Reduced energy utilization performed by the digital scroll compressor, that allows to modulate the power from 10% to 100%, saving more than 35% of absorbed electrical energy compared to the standard on/off units • Precise temperature control obtained with the use of: electronic expansion valve, digital Scroll, PLC controller (high precision +/- 0.3°C) • Reduced running costs ensured by the integral free cooling feature • High efficient heat exchange, braised plate evaporator and condenser in AISI316 stainless steel • Long life and reliability • Compact design • Easy to use HMI, clear display of water temperatures and alarms
