LEVA CLASS® Controlled Lever Anti-Shock System.
The first La San Marco patented technological innovation for lever machines to improve mechanical espresso extraction in full compliance with international safety standards.
PID SYSTEM
The PID system - Proportional-Integral-Derivative – works by electronically modulating the energy supplied to the heating element, thereby maintaining the temperature constant and thus replacing the current pressure switch which is unable to guarantee constant temperature.
The PID system boasts many advantages:
• Environmental: PID control allows the machine to reach a high level of energy efficiency and therefore a reasonable use of non-renewable sources.
• Practical: regulating the water temperature in the boiler becomes easy, quick and intuitive and can be carried out directly by
the operator without any intervention by a technician;
• Espresso customisation: controlling the water temperature in the boiler is the basic pre-requisite for a good espresso coffee, the PID control system quickly enables espresso coffee to be customised according to customer tastes and the coffee blend used;
• Appearance: removing the pressure switch and all of its
components enhances the clean and elegant design of a machine like Leva Luxury, characterised by its transparent glass bodywork;
To the traditional five key elements that go towards preparing a
well-made espresso coffee (Blend, Grinding, Machine, Maintenance,
Hand), La San Marco adds a sixth: Monitoring, essential for an even
better coffee.
