Profitec Pro 400 Heat Exchanger Espresso Machine

The Pro 400 uses an E61 group head with a 4.5kg brass thermal mass, which resists the temperature drops that cause sour, under-extracted shots. A discreet three-way switch beneath the chassis lets you toggle between temperature presets for light, medium, or dark roasts, backed by a 1.6L insulated stainless steel boiler for fast steam recovery. A switchable pre-infusion mode soaks the puck gently at low pressure before full pressure engages, reducing micro-channeling, and an externally adjustable OPV lets you fine-tune brew pressure. Dual pressure gauges show boiler and pump readings together. Interchangeable colored valve inserts (red, green, blue, yellow) let you personalize the front panel, and an insulated no-burn steam wand delivers strong, dry steam for microfoam. Water reservoir: 2.8L with automatic low-water shutoff. Boiler: 1.6L stainless steel, heat exchanger type; power: 1400W at 230V; group: commercial 58mm; dimensions: 228 by 448 by 372mm (without portafilter); weight: 21.5kg.
