Ultrasonic & DI water — the support cast

Great cleaning is 90% water and maintenance

Bench ultrasonics for parts too small for cabinets, DI plants that keep every rinse loop at 18 MΩ, and the consumables program that makes all of it boringly reliable.

DI Water Plants — DI-250 / DI200 / DI-1000

Own your rinse water: RO + mixed-bed deionizers feeding wash cabinets at 18 MΩ. DI-250 makes 250 L/h; DI200 (200 L/h) drops beside a stencil cabinet; DI-1000 supplies full lines. No more bottled DI, no more conductivity surprises mid-shift.

How it works

TO WASHER

  • Cavitation — 40 kHz transducers drive cleaning solution into every bore and thread; parts come out like new.
  • RO — feed water passes a >98% desalination membrane.
  • Polishing — the terminal mixed bed delivers 18 MΩ water straight to your washer's rinse loop.
  • Monitoring — conductivity meters log every rinse; salt-regeneration is a 20 kg brine task, twice a year.
Equipment selection guide

Which machine fits your EMS line?

Tell us your product mix and we will spec it — this section shows how we typically match lines to factories.

S-40A / S-100A

Parts benches & labs

Start with 10 or 30 L of 40 kHz cavitation; baskets sized to nozzle trays and blades.

Cabinet companion

DI-200 / DI-250

One washer, one plant

Pair a cabinet; get independent rinse purity without municipal-line surprises.

DI-1000

Whole line

Feed in-line washers, ultrasonic trains and final-rinse stations from one RO plant.

Return on investment

Cleaning pays for itself — fast

18 MΩRinse purity you control in-house
250 L/hDI-250 output at >98% desal
40 kHzCavitation frequency, 4–10 elements
600 WUltrasonic power (S-100A)

DI water sold in drums costs more per month than the plant that makes it. The datasheets show payback inputs.

FAQ

Questions EMS engineers actually ask

Ultrasonic vs spray — which cleans my nozzles?
Through-tip spray (S-6200) clears bores; ultrasonic tanks handle external coating and multi-part batches. Many EMS sites run both, which is why we sell both.
How pure is 'DI' here?
RO permeate polished by terminal mixed bed — 18 MΩ class on the datasheet; cabinet conductivity meters log it live during rinse.
Space for a DI plant?
DI200 footprint is 1100×1100×1600 mm — one floor tile next to the washer.
Do you ship consumables with machines?
Yes — one PO covers machine, 12 months of filters/paper/salt. WhatsApp us for the starter-pack list.
