One of the key challenges for institutional buildings (schools, universities, and hospitals/health care) is getting the best possible performance from the HVAC chiller while keeping maintenance costs to a minimum. Institutional buildings need their HVAC chiller systems operating at peak performance due to the high number of operating hours but also need to keep maintenance costs low because of limited maintenance staff and budget.
Oil-free compressors can be the right choice to meet these needs by offering unique capabilities in terms of performance while also reducing maintenance costs when compared to traditional compressors using an oil management system. Traditional compressors, such as screw type, require oil for several reasons, including lubrication of the compressor bearings to support the movement of the rotor and to form a seal to prevent refrigerant from traveling in the opposite direction.
