OTP Compact is a mobile unit engineered for on-site dehydration, degassing, and filtration of transformer
insulating oil, providing a variable flow rate range of 500–12000 L/h.

It features a heavy-duty vacuum pump and booster if required, capable of achieving –0.5 mbar in the degassing
chamber, ensuring efficient removal of dissolved gases and moisture. The precision heat exchanger distributes
uniform heat from 1.5 to 2.2 W/cm2, maintaining optimal oil quality.

Purification is completed through a three-stage filtration system utilizing 1 μm filters (99.98 % efficiency).
The plant’s compact and mobile design enables fast deployment, easy transport, and reliable eld operation.
