Automatic oil return becomes easier

摘要

Titan engineering has launched the latest Witt barrel dosing pump, BDP2, which, managing director, Don Belcher, says has many advantages for automatic oil return in refrigerant systems. Among the advantages claimed for the BDP2 are that manual oil draining is not required; internal damping allows the use of hot gas at high pressure to be injected to activate the BDP2; it can be operated at fixed time intervals or activated when needed by the addition of a Witt supplied electronic level sensor; it's relatively simple to install in new systems compared to a conventional manual oil drain vessel; it is adaptable to changing system requirements and has a design pressure of 40 bar.
