Water-efficiency tests demand strict water quality, pressure and temperature; mains supply drifts with seasons so batches cannot be compared, and high-flow tests stall halfway when the supply runs out.
Thermostatic constant-pressure supply system for purifier water-efficiency, life, desalination and recovery tests. Twin 2.0m3 SS304 insulated tanks supplying alternately or together, 1m3 effective volume; outlet pressure 0.05-1.0MPa with 0.01MPa resolution and 0.5 percent accuracy, set-point fluctuation not over 3 percent; one outlet delivering up to 40L/min for over one hour with refill interval under one hour; water temperature 5-35C settable, fluctuation under 1C, drift within plus/minus 1C per 2h, 0.1C display; scroll-compressor cooling with electric heating balanced by PID; VFD plus multistage booster pump and surge tank for constant pressure; high/low level monitoring, overflow protection and over-temperature cut-out; fully insulated piping (end-to-end difference within plus/minus 0.5C). PLC with touch screen, Pt100 class A sensors, imported pressure/level transmitters and Keyence flowmeters. AC380V 50Hz.
Water-efficiency laboratories per GB 34914; feed-water for purifier makers efficiency and life test benches; government testing of water-treatment products
