The Magister Stella Professional with PID combines classic Italian engineering with modern temperature control technology. Built around the legendary E61 group head, this heat exchanger espresso machine features a robust 1.3-litre copper boiler and professional-grade components throughout. The integrated PID controller delivers precise temperature stability while eliminating the need for cooling flushes typically required in heat exchanger machines. Its thermosyphon circulation system ensures consistent heat throughout the group head, while the powerful heating element maintains stable temperatures during extended use.

The machine's commercial-grade construction is evident in every detail, from its polished stainless steel housing to the no-burn steam and hot water wands with Teflon inserts. The E61 group head, a cornerstone of professional espresso making for over 50 years, operates through a classic lever mechanism that activates both the vibration pump and group solenoid valve. A three-way solenoid valve ensures clean, dry coffee pucks by relieving pressure post-extraction, while the automatic water refill system maintains consistent boiler levels for uninterrupted operation.

The heat exchanger design allows for simultaneous steaming and brewing, making the Stella Professional an ideal choice for home baristas who enjoy crafting milk-based drinks. The machine's vibratory pump delivers consistent pressure for proper extraction, while the PID controller allows for precise temperature adjustments to explore different coffee origins and roast profiles – perfect for those who love to experiment with their morning cappuccino or afternoon flat white.
