How a 5L Dual Boiler System Enhances Café Efficiency – A Technical Breakdown

1. Heating & Boiler System

• Stainless Steel Explosion-Proof dual boilers (5L + 1L x2)

  • Material: Food-grade 304 stainless steel, pressure-resistant design

  • Advantage: Independent control of brew/steam temperatures, ≤±0.5°C fluctuation during continuous extraction

  • Tested data: Boiler recovery time ~45 sec (industry average: 60+ sec)

• Saturated Group Head with Water Circulation

  • Copper tubing for minimal heat loss

  • Measured group head stability: 93°C ±0.3°C (industry standard: ±1°C)

2. Control & Operation

• Dual PID Temperature Control + T3 Logic

  • Independent PIDs for brew/steam boilers

  • Tactile buttons + backlit stainless switches (humidity-resistant)

  • Extraction timer precision: 0.1 sec

• Dual Pressure Gauges (Real-Time Monitoring)

  • Brew pressure (adjustable 9 bar) & steam pressure (1.5 bar)

  • Pressure fluctuation range: ±0.2 bar

3. Critical Performance Components

• US-Imported rotary pump (Non-Vibratory)

  • Flow rate: 2.2L/min, noise <55dB

  • Lifespan: 50,000 hours (~6 years of continuous use)

• 4-Hole 360° Steam Wand

  • milk frothing time: 25-30 sec (single-hole: ~45 sec)

  • Material: 316 stainless steel (corrosion-resistant)

4. Practical Design Features

• Large Cup Warming Area

  • Holds 12 standard cups or 6 mugs

  • Warming temperature: Adjustable 40-60°C

• Stainless Steel Drip Tray

  • Removable design, splash-proof
