Triton’s liquid ring systems (T1500, T2000, T2500) can use water or other service liquid. The water is spun in the pump to create the vacuum, and circulates in a loop through the water tank, which holds 250 gals when full to the middle of the sight glasses. Under full vacuum load conditions for an extended period, the water can reach a temperature in the range of 155F, which results in evaporation at the exhaust tower. At full load, the loss of water can reach ~8 gals/hour. However, Triton units are designed to be filled via an auto-fill float valve if fresh water is available. Simply connect a 1″ hose via a Chicago fitting on the side of the tank. New water then constantly replenishes the lost volume.
