Key Features & Benefits
✅ Independent Dual‑Boiler System ：Separate extraction boiler (2L) and steam boiler (6L) with individual temperature control. Brewing and milk‑steaming can run at the same time without temperature conflict. No waiting between pulling shots and frothing milk, greatly improving service efficiency during rush hours.
✅ Imported 9‑Bar Rotary Pump ：Maintains stable 9‑bar extraction pressure with minimal pressure fluctuation. Compatible with both municipal tap water and bottled water supply modes. Stable water pressure brings full‑bodied espresso with thick, rich crema shot after shot. ✅ Full‑Copper Heat‑Exchange Group Heads & Pre‑infusion Function :Full‑copper brewing groups preserve stable extraction temperature. Built‑in pre‑soaking releases CO₂ from coffee grounds before high‑pressure extraction, prevents channeling and achieves even, balanced flavor extraction. High‑density water outlet holes guarantee uniform water distribution over coffee puck. 
✅ Dual Independent Steam System for Superior Milk Texturing ：Two heavy‑duty steam wands deliver powerful, dry saturated steam. Fast milk frothing for silky micro‑foam perfect for professional latte art. You can brew espresso and steam milk on both groups simultaneously to handle multi‑order bursts. ✅ Dual Pressure Gauges for Precise Brewing Tuning Dual dial manometers show real‑time boiler pressure and extraction pressure. Baristas can visually adjust grind size, dose and extraction parameters conveniently to dial‑in different coffee bean profiles. 
✅ Rich Programmable Commercial Functions
- Adjustable brew temperature range: 30℃‑98℃
- Programmable pre‑infusion time & pause interval
- Customizable extraction flow rate
