The suction pump (15) draws air from within a drainage tank (13), so that an air flow directing toward the drainage tank (13) is generated in a drainage pipe (11) to promote recovery of a waste fluid.

If the drain tank is full, the fuel from it can be pumped into the tank of another aircraft or tank truck.

A blowdown tank (10) delivers fuel to a reaction site, produce gaseous products.

A first step of the process is to open a drain port (50) in a hydraulic system (20) of the heavy equipment piece and drain used hydraulic fluid therefrom and into a waste reservoir (55) that is maintained exterior to the equipment piece itself.

Moreover, you need to clean not only the product itself, but also the drain tank.

The controller (220) responds by operating a divert valve (222) to direct the treated product away from a batch tank to disposal tank.

Very convenient thanks to fully automated and adjustable disposal of collected particles in the desludging tank

On one flush is due to the water, then all the products fall into a drain tank.

Triotank Vacuum Tank, International Patent Pending, is the world’s first vacuum tankmade entirely of Polyethylene.

Put the drain tank if it is separate - you need to act carefully, combining all the holes and trying not to damage the device inside the tank;

A cleaning solution is then injected into the hydraulic system (20) that purges remaining undrained hydraulic fluid from the system (20) and into the waste reservoir (55).
