A passive system is an oil management system
without any measurement or control devices
such as oil level regulators and oil controllers.
By contrast, a solution equipped with such
measurement or control devices is called an
active system.
Danfoss has qualified only the even tandem
(two same compressors)
for passive solutions
.
