A spark-free booster for ice-machine water purification.

Why brushless next to R600

Commercial and residential ice machines that use R600 keep a flammable hydrocarbon charge in the refrigeration loop. The PEILI 605 is specified for the water circuit that feeds or purifies that machine — ice-machine water purification — not as a refrigerant pump. The safety claim is narrow and published: no carbon-brush contact, so no spark at the motor. That is the difference versus a conventional brushed RO-style booster sitting in the same cabinet.

• No carbon brushes, no commutator spark.
• Magnetic isolation sleeve; motor-side sealing concept to IP68.
• Speed, flow and pressure adjustable from the driver if the ice machine’s water system needs more than one operating point.
• Same 605 pump head as PEILI’s RO family, so brackets and ports can follow an existing water layout.

Factory tests that still apply

The ice-maker water circuit still sees pressure spikes when valves close. The Jiangmen stand bursts the wet end at 3.5 MPa and runs 1.2 MPa water hammer for 120,000 cycles. Outlet max on the nameplate remains 150 psi.

• Type-test burst: passed 3.5 MPa (~35 bar / 508 psi). That is not the working pressure.
• Water hammer: 1.2 MPa for 120,000 cycles, then leak, flow and pressure re-checked.
• Life / endurance run under load on the Jiangmen comprehensive stand.
• Every serial unit still goes through nine outgoing benches: air tightness, mechanical properties, flame retardance, flow, noise, pressure, load, hot/cold, material reliability.
