5. Flow (pressure), time control system

Working mode High-pressure water pump → three-way → nozzle and balance pressure outlet → electromagnetic flowmeter (pressure gauge, 100bar) → four-way (controlled by solenoid valve, solenoid valve set by time → controlled by the controller) (Four high pressure nozzles: 0, 30, 60 and 90 degrees), at each angle for 30 seconds, a total of 120 seconds (2 minutes), the cycle of work.

6. Working mode BT (H) C Balance thermostat mode.

When the water temperature through the nozzle after the hot steam scouring test, less than 80 ± 5 ℃, return to the tank, the tank heating system automatically heated (4KW), in a short time to maintain the water temperature at 80 ± 5 ℃, to ensure that The test water temperature runs normally. The touch screen controller can be set to display the temperature of the water.
