EcoDose 3K — Three-Component Electronic Dosing
Three streams. One precise mix.
An electronic dosing system for three-component paint processes — independently metering base paint, catalyst, and additive at programmed ratios across the full production shift, with per-component pot life monitoring and independent flushing circuits.
Why this product
Three-component mixing multiplies every ratio error.
When a paint system requires a base, a catalyst, and a separate additive — each at a precise ratio — the compounding risk of manual measurement grows with every component. A small error in component C doesn't just affect that stream; it shifts the whole mix ratio and can invalidate the cure chemistry. The EcoDose 3K removes human ratio error from all three streams simultaneously.
- Three independent electronically metered streams — base paint, catalyst, and additive each controlled separately
- Programmed mix ratio maintained precisely across the full shift — no operator variation between batches
- Per-component pot life monitoring: each stream tracked independently with process alerts for ratio deviation
- Independent flushing circuits for all three components — no shared premixing chamber to purge
- Colour change with minimal waste — each component circuit flushed without contaminating the others
- Covers the same 40–4,000 cc/min flow range as EcoDose 2K — from touch-up to full production volume
How it works
Supply, ratio, flush — three streams
Three-stream supply and metering
Component A (base paint), Component B (catalyst/hardener), and Component C (additive or accelerator) are supplied from separate EcoPump packages to the EcoDose 3K dosing unit. Each stream is independently measured — by Coriolis or gear flowmeter — continuously and in real time. No component contacts another before the mix point.
