ACS (Advanced Coffee Solution)

ACS machines uniquely combine Italian handcrafted quality with innovative technology, including the only spring lever machines with dual boiler systems and independent PID temperature control. Each machine is built in Italy with high-quality materials and undergoes rigorous testing before shipment, ensuring café-quality performance that will last for decades.

ACS designs machines for both environments. Models such as the Minima and Vostok 1G offer professional features in compact, home-friendly formats, while the multi-group Elysium machine is suitable for the high volumes of cafés. All models feature durable, commercial-grade components.

With proper maintenance, ACS machines are designed to operate reliably for more than 20 years. Their mechanical simplicity, high-quality stainless steel construction, and repairable design ensure fewer breakdowns and a longer service life compared to alternatives with a lot of electronics.

Dual boiler systems have separate boilers for brewing espresso and frothing milk, allowing you to do both at the same time without having to wait for temperature changes. This delivers consistent, café-quality results at home and professional work efficiency.

Lever devices offer manual pressure control throughout the extraction process, enabling unique flavor profiles and pressure profiles. Pump devices provide consistent automation. ACS lever devices combine manual control with modern PID temperature stability, making them easier to operate than traditional lever devices.

Most ACS machines with double boilers reach brewing temperature in 12-15 minutes, depending on the model and voltage. The coffee boiler is heated first, followed by the steam boiler. Many owners use timers to get started quickly in the morning.

PID (Proportional-Integral-Derivative) control ensures an accurate, stable brewing temperature by automatically adjusting the heating elements. This eliminates the need to guess the right temperature and allows you to prepare espresso recipes consistently, which is crucial for brewing specialty coffees.

Yes. All ACS machines are equipped with professional steam pipes that allow you to produce café-quality microfoam. Thanks to the powerful steam capacity, you can quickly froth milk and make multiple milk drinks in succession without any loss of temperature.

Each machine is built in Italy with high-quality materials and undergoes rigorous testing before shipment, ensuring café-quality performance that will last for decades.

ACS offers comparable or superior features at more competitive prices. The unique combination of lever mechanics with a double boiler and independent PID control is exclusive to ACS. While other brands add complex electronics, ACS prioritizes mechanical simplicity for reliability and long-term value.

You can purchase ACS espresso machines via Vellutto.nl.

Vellutto.nl offers a 24-month warranty on parts for all machines.

No. ACS machines are designed for easy maintenance: annual descaling, periodic replacement of seals, and occasional maintenance of the pump. Mechanical simplicity means fewer electronic malfunctions and readily available parts. Most owners perform basic maintenance themselves.

Regular maintenance includes descaling every 6-12 months (depending on water hardness), weekly backwashing of the group head, replacement of gaskets/seals every 2-3 years, and occasional inspection of the pump. ACS provides maintenance guides and responsive technical support.

Filtered or mineral water is highly recommended to prevent limescale build-up and extend the life of the machine. Hard tap water accelerates the need for maintenance and can affect the taste. Many owners use simple carbon filters or bottled water for best results.

ACS lever machines have a learning curve, but PID temperature control removes one key variable, making them more accessible than traditional levers. Most users achieve basic proficiency within 2-4 weeks and consistent quality within 2-3 months. Community support is excellent for the learning process.

Yes, every good-quality espresso machine needs a good coffee grinder that can grind the coffee beans finely enough for espresso. For the best results, you should invest in a good coffee grinder that suits your machine.

Last Shot Protection is an ACS innovation that prevents coffee brewing from being interrupted halfway through when the water is almost empty. Traditional machines stop immediately, causing the coffee to be lost. ACS machines complete the coffee brewing process using residual pressure and then alert you to refill the water, saving you coffee and frustration.

Most ACS machines support both reservoir and pipe connections (direct water supply), making them flexible for home or commercial use. This allows them to be adapted to different environments and usage volumes.

Pressure profiling means that the extraction pressure varies during brewing: starting low for a gentle pre-infusion, then increasing to peak pressure and then decreasing again. This technique brings out different flavor profiles, especially in lightly roasted specialty coffees. ACS lever machines excel at manual pressure profiling.

ACS machines offer some customization options, including different types of steam pipes (Minima, Vostok, or Vesuvius designs) and adjustments for flow control. However, the machines are already well designed, so major modifications are usually not necessary.
