Ultra Low Noise Air Cooled Chiller with Screw Compressor
Due to increasing awareness of noise as an environmental pollutant, Petra Engineering Industries Co. developed the Ultra-Low Noise chillers with the lowest dBA level on the market today geared towards noise-sensitive design requirements.
Petra designed the Ultra-Low Noise chillers using their “Patented Design” for the compressor compartment. In addition, the chillers use the highly efficient, low noise screw compressor and cast aluminum sickle-shaped fans with high efficiency external rotor motor, to further reduce noise levels.
When measured against the AHRI standard, the highest dBA of Petra’s chillers is lower than the minimum dBA requirement for the same tonnage listed in the ASHRAE standard. In addition, these chillers can be supplied in systems up to 1760 kW (500 Tons) and take into consideration the chiller COP in both part load and full load values.
Petra Ultra Low Noise chillers have been installed in projects that have strict sound regulations such as schools, universities, libraries and large commercial projects in residential areas of the USA, UK and other countries, where noise control is imperative. The chillers were installed near the building with minimal noise disruption to its occupants and its surrounding neighbors.
