The problem

Outlet temperature, power deviation and pressure sealing are the three hard failures of coffee machine boilers; finding them after assembly means teardown rework, and manual gauge reading is slow and skips items.

Capability

Heating boiler comprehensive tester for factory function and sealing checks of coffee machine extraction and steam boilers. Four stations with independent start; supply pressure 0.3-1.2MPa at 0.25 percent accuracy; outlet temperature ambient to 120C (0.25 percent); built-in boiler temperature control working with the appliance control board. Verdict logic: stable outlet temperature band, measured power within 10 percent of rating by digital power meter, pressure 9 plus/minus 1bar held over 10 seconds; flow includes dosed water fill (e.g. 1.5L), relay-simulated power-on, warm-up wait and steam-path condensate check (wet steam fails); PT100 sampling, digital power meter, analogue pressure input, level input and water-leak sensor cutting water and power; hard-wired emergency stop; 10-inch touch screen with PLC (Modbus TCP to MES), pneumatic valves and tower lamps; 30L purified-water tank, 3.5kW maximum per station (external load supply) with 10A/16A and multi-use sockets; aluminium frame with painted panels and stainless tank.

Applicable standards

Per customer technical agreement; factory function and sealing inspection of coffee machine heating boilers
