The cooling suit runs off of the same onboard battery that powers the suit's lamp, fan, and comm link; a pump circulates a liter of ice water (stored in a specially shaped bottle) from head to toe.

Now the pressure head of the pump is not able to make precise calculations in theory, the general use of experimental methods.

In the process conditions permit, the change in pump flow, head, speed and medium operating temperature operating parameters, to avoid the occurrence of cavitation.
