KITANO commercial equipment consists of water-cooled and air-cooled chillers with heat pumps or centrifugal compressor. All equipment is available in three acoustic versions: "N", "SN", "SSN".
"N" - Standard acoustic performance. Compressors are directly accessible from outside the unit. The fan speed is approximately 900 rpm.
"SN" - Low Noise Acoustic Performance. Compressors are located in a fully insulated sound-absorbing coating of cellular polyurethane foam in a metal box. Fans have a reduced rotation speed of 700 rpm.
“SSN” - Super low noise acoustic performance for operation with minimal noise. Compressors are installed on anti-vibration supports and connected to discharge and suction lines by means of flexible hoses with silencers. These are located in a metal box covered with sheets of sound-absorbing material and a layer of flexible cellular polyurethane foam. The condenser section has an increased size. Fans with a low speed of rotation of 580 rpm (except for the last five models).
