Necta Koro Max

At 330 mm width, 530 mm depth and 620 mm height, the Necta Koro Max Prime occupies less counter space than many tabletop OCS units in its price segment. At 28 kg, the weight is distributed across a robust cabinet that stands securely on a standard kitchen counter without additional mounting. When the door opens, the unit extends up to 724 mm in depth; tight fitted kitchens and under-counter installations require pre-measurement.

The control panel combines a 128 × 64 pixel graphics display with backlight and tactile selection buttons. There is no capacitive touchscreen. The resistive buttons respond reliably even with protective work gloves, which is a practical advantage in service environments. In a pure office context, the graphics display appears technologically dated compared to current OCS models with colour displays and capacitive touch. The graphics display is sufficient for the eight preset selections and status indicators, but does not offer multilingual menu navigation or customizable tile layouts.

Blue LED lighting at the door and dispensing area subtly highlights the unit. The cabinet comes in standard grey-black with no colour options or interchangeable face panels. For locations with corporate identity requirements, the Koro Max Prime offers no customization.

Two variants are available: the mains-fed variant (ES+2IN mains-fed) connects permanently to the water supply; connection pressure 0.5 to 8.5 bar, 3/4-inch thread. The tank variant (ES+2IN tank) holds 2.75 litres and suits locations without direct water connection. Above 50 vends daily, the tank variant reaches its refill threshold and must be topped up multiple times daily. Price difference between variants in DE: approximately €200 net in favour of the mains-fed entry model.

Product generation: Necta no longer lists the Koro Max on the current manufacturer website (as of August 2026). This device comes from the Evoca product generation predating 2020. DE and AT retailers including ECMshop, All4Vending and ATTIA still sell from existing stock. The cabinet design reflects the compact approach typical of that era, at the expense of modern display and connectivity technology.

For locations seeking a narrow tabletop unit with genuine espresso capability and no design aspirations, the Koro Max Prime fulfils its purpose. Operators requiring modern user interfaces, remote service capability or long-term manufacturer support should evaluate current units from the Evoca range.

The core component is the Z3000 L espresso brewer with a maximum dose of 12 g. This brewer produces genuine espresso through brewing pressure, not via instant process. This distinguishes the unit from pure instant-OCS machines and justifies its positioning in the mid-market segment. The steam boiler holds 0.5 litres and supplies both hot water dispensing and powder-based milk frothing simultaneously.

Milk system: powder only. A fresh-milk connection, automatic cappuccino maker and steam wand are not present in the design (manufacturer specification, confirmed by several DE and NL retailers). Milk-based drinks such as cappuccino and coffee with milk are produced by mixing hot water with instant milk powder from the 750 g container. Foam quality falls short of fresh-milk systems. For locations where milk quality is a purchase criterion, the Koro Max Prime is unsuitable.

Beverage menu: eight preset selections. According to retailer information, these comprise espresso, caffè, coffee with milk (powder), cappuccino (powder), chocolate, hot water and decaffeinated. The decaffeinated option is standard; whether routing occurs via instant granules or a second dose chamber depends on the variant designation ES+2IN.

Connectivity and telemetry: none. Analysis of all available retailer and forum sources reveals no IoT module, wireless or Ethernet interface on this device. Remote monitoring, push notifications and remote configuration are not possible. This reflects the technical state prior to 2020; current Evoca devices offer optional telemetry modules.

Payment interface: according to the 2019 UK datasheet, an external payment module is listed as optional accessory. No MDB variant is specified in any available source. Contactless or mobile payment as standard: not present (manufacturer specification not independently verified). Operators requiring payment integration must add external hardware and account for the absence of MDB specification.

Rated power 2030 watts, supply voltage 220 to 240 volts / 50 to 60 hertz: European standard connection via Schuko plug. The brewing technology delivers genuine crema in espresso and caffè; milk drinks do not benefit, as the fresh-milk system is absent.

The manufacturer datasheet cites 80 espressos per hour as throughput. Distributors such as Happy Donkey (UK) recommend approximately 50 vends daily as a practical daily average. The discrepancy reflects idle periods, refill interruptions and limited bean hopper capacity.

The coffee bean hopper holds 950 g (figure from DE retailers ECMshop and All4Vending; NL retailer lists 750 g, likely a different variant). At typical consumption of approximately 8 to 10 g per vend, 950 g yields 95 to 119 espressos. At 50 vends daily, refilling is needed every two days; at 80 vends daily, refilling is required daily.

The milk powder container holds 750 g; the chocolate container holds 1,500 g. The latter is relatively generous for a tabletop unit of this class. At 20 chocolate vends daily, one fill lasts approximately three weeks without refilling.

Water supply: the mains-fed variant connects permanently to the network with no internal reservoir. The tank variant holds 2.75 litres. At typical water consumption of 50 ml per espresso and 100–150 ml per milk drink, the tank yields approximately 25 to 35 vends per fill. This means: above 50 vends daily, the tank variant must be refilled twice daily. For this duty, the mains-fed variant is clearly more economical.

Grounds drawer: 25 to 30 portions. Waste water reservoir: 1 litre. At 50 vends daily, the grounds drawer must be emptied every other day. No external fill-level indicator is visible; status can only be checked by opening the door, which triggers a complete device restart.

The eight-preset menu covers the basic needs of an office location: espresso, lungo, coffee with milk, cappuccino, chocolate, hot water, decaffeinated. For locations expecting a broader speciality range or fresh-milk drinks, the menu is too limited. For classic office-coffee locations focused on espresso and basic hot beverages, it is adequately sized.

Daily cleaning: approximately 5 minutes. Empty grounds drawer, rinse drip tray, wipe powder discharge spout. These steps can be performed by office staff without technical training. Weekly tasks add approximately 15 minutes: remove milk and chocolate containers, rinse separately, clean mixer channel and dispensing area. No automatic descaling programme is documented. Descaling is manual; at moderate water hardness (14–21 dH) approximately every three months.

Special note on door opening: each opening of the service door triggers a complete device restart. Every refill operation for beans, milk powder or chocolate interrupts service for the duration of the restart cycle. This behaviour is noted in forum reports and reflects the design principle of this series. It is not a malfunction, but it does limit flexibility during frequent refilling.

Spare parts and repair costs (parts prices excluding technician labour, guide values from DE specialist retailers):

- By-pass pump: €37–60 (wear part after 3–5 years continuous operation)

- NTC temperature sensor: €68–90 (for boiler control issues)

- Boiler with heating element: €207–383 (for limescale damage or failure after several years of operation)

- Valve block 4-way: €223–280 (for water leak or solenoid failure)

- Solenoid valve 4-way 230 V: €354–420 (for water intake errors)

Service infrastructure for Necta devices across the DACH region is not nationwide. Specialist retailers such as gerds-coffeehome.de and libertyshop.de offer spare parts mail order; delivery times of 3 to 10 days have been reported in forums. Contractually guaranteed SLA response times are not documented.

For operators with in-house service technicians, the effort is manageable. For locations without dedicated technicians, a failure means several days of downtime. A maintenance contract with a local service provider should be agreed before commissioning. Proximity to an Evoca-competent technician is a relevant factor in site selection.

The Necta Koro Max Prime has a rated power of 2030 watts (manufacturer specification, confirmed by ECMshop DE, All4Vending DE and uwkoffieleverancier.nl NL). The supply voltage lies in the European standard range of 220 to 240 volts / 50 to 60 hertz; a standard Schuko plug is sufficient, no heavy-duty installation required.

Standby power: no public figure available. Neither datasheet, retailer listings nor technician forums specify a standby value. Annual consumption estimates can therefore only be given as a range: assuming 8 hours daily of active heating at 2030 watts yields approximately 5,900 kWh per year from this alone. Adding standby hours (typical OCS units: 5 to 30 watts), estimated annual consumption lies between 6,000 and 6,500 kWh at 8-hour daily operation. This estimate is not verified; on-site measurement with an energy monitor is recommended for precise figures.

Warm-up time from cold start: no public figure available. Comparable Evoca devices with 0.5 litre boilers typically require 2 to 4 minutes to reach operating temperature from field experience; this estimate is not sourced from Necta documentation.

Noise level: not specified in datasheet or retailer sources. The grinding process and pump produce standard espresso machine noise; specific dB(A) values are not available.

Throughput: 80 espressos per hour (manufacturer specification). This equates to approximately 1.3 espressos per minute at full capacity, sufficient for morning peaks in offices with up to 80 people. Where more than three people require beverages in close succession, brief waiting times arise.

The device carries no publicly accessible EU energy label certification. For commercial OCS tabletop units of this generation, an EU energy label is not mandatory. The eco-score C reflects missing consumption data and the absence of documented energy-saving modes.

List prices (August 2026, net): All4Vending DE offers the mains-fed variant from €3,105 net. ECMshop DE lists the same variant at €3,328 net (€3,959.73 gross incl. 19% VAT). The tank variant costs approximately €3,531 net at ECMshop (€4,201.89 gross). In Austria, the ATTIA price is €3,930 gross, equivalent to approximately €3,275 net at 20% Austrian VAT. The market ceiling comes from Dutch retailer uwkoffieleverancier.nl at €4,429 net (excl. VAT).

Used market: on Kleinanzeigen.de, Necta Koro units appear between €250 (defective units) and €1,500 VB (tested units). The UK retailer The Commercial Trader offered a tested unit at approximately €1,350 equivalent. Used purchase reduces capital outlay substantially, but increases risk regarding part availability and remaining service life.

TCO estimate (mains-fed variant, 5 years, 50 vends/day, 250 operating days/year):

- Acquisition €3,100 net, depreciation over 5 years: approximately €620/year

- Beans: 8 g/vend × 50 vends × 250 days = 100 kg/year; at €12/kg procurement approximately €1,200/year

- Milk powder + chocolate: approximately €300–400/year (depends on beverage mix)

- Energy: approximately €200–400/year (not verified, based on consumption estimate above)

- Maintenance and wear parts: approximately €100–200/year (excluding major repair)

- 5-year total: approximately €13,500–15,000

- TCO per vend: approximately €0.22–0.24 at 50 vends/day

For comparison: capsule OCS systems typically cost €0.40 to €0.80 per vend in materials alone, without unit acquisition. Instant systems without genuine brewing cost less to manufacture but deliver no genuine espresso quality.

Since this device is apparently no longer in active production, retailer prices and availability may change soon. Those requiring long-term planning certainty should evaluate current models from the Evoca range as alternatives.
