Gemilai Whale G3135H E61 Dual Boiler Espresso Machine with Flow Control

Gemilai Whale G3135H – E61 Dual Boiler with Manual Flow Profiling

The Gemilai Whale G3135H brings together a classic E61 pure copper group, two independent 1 L stainless steel boilers, an Italian Fluid-o-Tech rotary vane pump and a hands-on flow control paddle.

Built for serious home baristas and light commercial use, it lets you change the flow mid-shot, brew and steam at the same time, and run from the tank or a direct water supply.

Key Features

Stainless Dual Boiler System

Separate 1 L brew and 1 L steam boilers, each governed by its own PID, so brewing and steaming never compete.

• Brew and steam simultaneously
• Brew and steam temperatures set independently
• Stable temperature cup after cup

Classic E61 Copper Group Head

A pure copper E61 group with refined electroplating and thermosiphon circulation keeps the group at working temperature all day.

Flow Control Paddle

Variable pressure extraction through a flow adjustment rod. Ramp in gently, hold a plateau or taper the finish – genuine manual flow profiling.

• Slow pre-infusion for light roasts
• Taper the tail to reduce astringency
• Repeat what works

Italian Fluid-o-Tech Rotary Vane Pump

Quieter and smoother than a vibration pump and built for sustained, back-to-back use.

Three Pressure Gauges & Touch Display

Extraction, steam and water gauges plus a touch screen for temperature and time. Extraction temperature, steam temperature, pre-wetting and pre-infusion are preset and stored.

Flexible Water Supply

1.7 L removable tank or direct water supply, with an automatic supply and drainage system.
