Closed circuit cooling tower for the Rotor Dynamics Laboratory
The laboratory located at the University of Pisa has an area of 200 square meters and is located within the protected park of San Rossore. MITA Group provides a solution for the cooling system of the 2 engine test benches.
CHALLENGE
The laboratory, attached to the University’s Mechanical Turbomachinery Research Centre, was to be extended and modernised.
The laboratory test benches (approximately 1 MW total operating power) had a particular need: to preserve the quality of the cooling fluid, which should not come into contact with the air.
SOLUTION
The ideal solution to keep the quality of the coolant intact was to select a closed circuit MCC cooling tower. This cooling equipment keeps the coolant inside the metal coils and is cooled by a second, cooler water circuit. The E3-09 SILENT MCC closed circuit cooling tower, installed with the engine test benches, implements this technology.
RESULT
The installed closed circuit cooling tower has a power of 700 kW. The inlet fluid temperature is 50°C, the outlet temperature is 35°C, while the installed electrical power is 3.3 kW for the motors and 1.5 kW for the water recirculation pump.
As in other civil contexts, the noise developed had to be limited. The silent version of the closed-circuit cooling tower has been equipped with low speed electric motors, directly coupled to the fans with aerodynamic profile blades, and the sheath that absorbs the noise.
CUSTOMER BENEFITS
- Anti-corrosive fiberglass structure.
- Completely removable panels that allow easy, fast and total access to the internal parts of the installation.
- Side walls and water collection tank manufactured with specific color requested by the customer.
