Electrical components

Elements in Incoloy 800 stainless steel. Much higher quality than traditional copper ones. Withstands high temperatures and minimizes the possibility of overheating or failures if the machine runs out of water. Excellent resistance to corrosion and rusting in aqueous environments. Its structure remains stable during prolonged exposure to high temperatures). 100% food safe. Anti-lime scale material. The cover of the element (platen) is also made from AISI 316 stainless steel.

Solenoid valves in AISI 316 stainless steel.

Internal motor for continuous use (24 h). Manufactured by RPM. High power 245W. (2-3 groups).

Rotary pump in AISI 316 stainless steel. Procon 200 l.

Flow meters. State-of-the-art. More precise.

Top-quality static relays used in all electrical circuits.

High-quality safety thermostats in the coffee groups and steam boiler.

NTC temperature sensors in stainless steel in the coffee groups and steam boiler.

Heat-protected general wiring. Maximum protection and quality. 100% silicone wide section wiring. All wiring is sheathed in a silicone + glass fibre heat protection jacket (250ºC maximum resistance).

Filter holder/Filters/Seal rings

the filter holder is one of the most heavily used parts of the machine. It is important that the design facilitates the barista’s work.

We focused on various aspects of the handle:

Filter holder in AISI 316 stainless steel
Designed to adapt to the palm of the hand, conveying a pleasant sense of strength and safety in use.
The 10º tilt facilitates its use, allowing the hand to adopt a natural position.
Horizontal resting position of the filter holder for perfect tamping of the ground coffee.
The filter holder body has a flat base to facilitate optimum tamping.

Soft filter holder closing action: The precision-design of the group head and the conical design of the seal ring provide a smooth, streamlined and uniform feeling when coupling the filter holder to the group.

Coffee spouts in AISI 316 stainless steel. Thanks to the closing system these are always positioned centrally, making assembly and dismantling safe and easy.

HNBR seal ring

Material: HNBR. Hydrogenated. Can withstand temperatures of up to 160º. Our tests show that they have double the normal lifespan of standard high-quality rubber seal rings. Food safe material. In green.

Design: Specially designed rubber seal rings. Thick and flexible. The side grooves release air and water, making installation easier. The conical shape allows a smoother closing action than a traditional flat joint.

Competition filters in AISI 304 stainless steel. These are essential for optimum extraction. We only use high-precision filters. Only a top quality, cutting-edge production process can guarantee a consistent result. Filter by filter. Hole by hole. Otherwise, there would be significant differences in the cups and systematic extraction variations (over/under).

Main features:

1 mm thick AISI 304 stainless steel plate. The usual thickness is 0.6 mm. We guarantee 120,000 life cycles without any decline or change in the extraction quality. Our filters are designed to pass this life test.
Laser engraving, including a different serial number for each filter.
High-tech manufacturing process.
A well-manufactured filter has uniform, circular holes that are all the same size (maximum tolerance is 0.02 mm difference). This ensures consistent, uniform extraction of the entire coffee dose, Simplifying the preparation of an espresso, and reducing possible grounds in the drink.

The holes are produced using a highly precise perforating machine that guarantees uniformity of all the manufacturing parameters.

Tolerance of the diameter of the holes: +/- 0.02 mm.

Tolerance of the perforated surface area: +-1%

Geometry: Exclusive perforation system which ensures that 100% of the holes are clear and free from burrs, guaranteeing consistent extraction, reducing sedimentation in the holes and offering an anti-wear surface.

The holes have a pyramidal exterior and a circular interior. The exit angle is 94º to prevent build-up and guarantee uniform performance throughout the filter’s lifespan.

Finishing process and quality control.

cleaning by ultrasound.
high-gloss polish.
Quality assurance 100% of the holes of one filter in every 500 with a 2D projector. The test includes checks of the number of holes, diameter, circularity, total area and up to 12 other control criteria.

Configuration: The design of the filter is crucial. There are three factors to bear in mind: the diameter of the filter holes, the diameter of the perforated area and the depth of the filter. A balance between these three points is essential to produce a good espresso.
