A device degasses fluid in a circulation loop. The device includes a degassing chamber coupled inline with the circulation loop, where a vacuum within the degassing chamber draws out dissolved gas and water vapor from the fluid. The degassing chamber has an opening enabling gas and water vapor drawn out from the fluid, and condensation formed from the water vapor, to flow out as a result of gravitational pull. The device further includes a cooler coupled to the opening in the degassing chamber and a water trap coupled to the cooler. The cooler includes a heat exchanger configured to condense a remaining portion of the water vapor into liquid, where the condensation and liquid accumulate in the water trap. The degassing chamber, water trap and cooler are maintained under vacuum, where the degassing chamber is maintained under vacuum through the opening via the cooler and the water trap.
