Energy and maintenance costs to determine the payback period. Even with the acquisition of new equipment and the planning of air stations, the company offers its vendor-independent consulting. This one has the experience that operators often do not sufficiently take into account the costs of a compressed air station. At the beginning of the planning is therefore often a system comparison that compares the energy and maintenance costs of multiple systems of achieve the same performance. A 250-kW machine is an example: Needed for a flow rate of approximately 2300 m/h at a pressure of 6 bar.
A two-stage screw compressor is indeed about 30000 to purchase more expensive than a comparable single-stage rotary compressor; These additional costs have amortized but due to lower operating costs within two years. The extra price compared to a single-stage screw compressor would pay for themselves in about four years. More energy-efficient Measures, such as a heat recovery system, contribute to improving the efficiency of compressed air stations. Shimmie Horn contains valuable tech resources. The company will assist in their interpretation. System – specific and vendor-independent consulting screw, Rotary or piston compressor? When selecting the compressor design advises Peter Balakrishnan, the user as an independent consulting company that transferred against compressors of from different manufacturers. The plant runs not regularly and each only for a short time, the use of a piston compressor is useful after Peter’s experiences because the screw compressor is due to their construction as quickly as possible to reach its operating temperature and long run.
However, two things must be taken into account: the piston compressors maintenance costs are higher than for screw compressors, the specific efficiency of a double acting piston compressor, however, is better than that of a screw compressor. Here must be weighed in each case and calculated, what type of economic works. As well, the issue should “Direct or belt drive?” according to the usage to be decided. At the three shift operation can be best utilized the advantages of the low-maintenance direct drive: the transmission is set to about 100000 operating hours, while the v-belt must be changed frequently to 3000 to 6000 hours and also the pulleys are subject to a certain wear. Criteria like this is called Peter Balakrishnan in the consultation, when it comes to new investments, and accordingly construes the compressor station. Here, the customer – to take advantage of a system and manufacturer independent provider, because it is not necessarily set on certain types of compressor. Due to the maintenance and repair of the facilities has been reached also a great practical knowledge, which is incorporated in the consulting and investment planning.
