Most air-cooled products (including chillers, rooftop units, and condensing units) use DX evaporators. Most DX systems allow oil to travel through the refrigeration circuit and back to the compressor oil sump. Great care must be taken during design to provide oil return, particularly at part load, when refrigerant flow rates are reduced.Water-cooled chillers often use flooded evaporators. In a flooded evaporator, even small amounts of oil can coat evaporator tubes and significantly diminish chiller performance. This can lead to an elaborate oil-recovery system. Magnetic bearings eliminate the need for these systems and oil management in general. In fact, the only required regular maintenance of the compressor is the quarterly tightening of the terminal screws, the annual blowing off gas of dust and cleaning of the boards, and the changing of the capacitors every five years. Complete service agreements and extended maintenance contracts can be provided by the manufacturer.
