The versatile boosters can deliver compressed air up to 650 psig and are ideal, for example, for the supply of compressed air to PET bottle production plant where economical and energy-efficient, high-pressure air is required.
This finely graded series covers a power range of up to 25 hp. Now, the efficient two-cylinder N 253-G, N 351-G and N 502-G models are available in the smaller power range of 10 to 25 hp to cover pressure requirements up to 650 psig. The Kaeser N-series boosters are two-cylinder reciprocating compressors running at very low speeds between 740 and 1320 rpm with power ranges from 10 to 25 hp. Initial pressure is between 75 and 190 psig, discharge pressure up to a maximum of 650 psig, and flow rates are between 35 and 194 cfm. On the two-cylinder versions manual belt drive tensioning reduces the need for maintenance and guarantees optimum power transmission to the compressor block. An efficient idling control provides additional energy savings by enabling the compressor power to be precisely and economically matched to suit the actual discharge pressure required. Special air ducts integrated in the drive belt guard ensure efficient cooling. The two-cylinder boosters are fitted with a generously dimensioned air-cooled aftercooler to provide optimum temperature conditions for subsequent air treatment units.
The combination of these boosters with Kaeser's energy-saving rotary screw compressors allows the implementation of extremely flexible and economical compressed air concepts for a variety of compressed air applications up to 650 psig. A typical area of application is the supply of compressed air to PET container production plant. With “Sigma PET Air”, Kaeser provides complete system solutions tailored to such needs.
