Necta Kalea Plus

368 mm width, 586 mm depth and 783 mm height per current manufacturer specifications for the Kalea Plus. Unlike many foodservice coffee machines, the unit stays well under one metre height; at 47 kg, however, it enters the category where single-person installation is not feasible. When the door opens, plan for 854 mm depth. Airflow requires minimum 40 mm clearance from the wall per spec—often overlooked in fitted cabinetry. Placement is strictly limited to dry indoor environments between 2 and 32 °C; outdoor stations or open foyers are ruled out, a common constraint for office and HoReCa ranges.

Notable is the control concept: a 7-inch touchscreen per German datasheet, tactile input across all functions. Beverage selection uses either ten direct-select buttons per screen or scrolling; screen count is undocumented as unlimited. Outlet height adjustment spans 75 to 170 mm, accommodating espresso cups and tall coffee mugs alike. Custom backgrounds and icons can be configured by the operator—automated voice prompts or gesture sensing are not documented.

Where add-on modules are planned, space must be allocated for optional refrigeration units and rolling undercabinets. For optional refrigerators, the manufacturer specifies 190 or 290 mm width. The option to mount the unit on mobile undercabinets of 700 or 1,000 mm width clearly targets flexible deployment or sites requiring cleaning access beneath the machine. A typical value-add in high-traffic offices with dedicated service staff.

Two grinders with self-adjusting grind settings, each holding up to 1.2 kg bean capacity. The mills draw on the Z4000 brewing platform deployed across the Evoca Group, dispensing 7–14 g per brew cycle (ref. Necta, Datasheet 2024, p. 4). Powder preparation covers chocolate (1.8 kg), milk powder (0.75 kg) or instant barley (0.5 kg), depending on ordered configuration. Dual-bean plus instant-module operation eliminates peak-hour bottlenecks common to single-grinder setups at high-volume sites. Menu flexibility is confined to the hardware configuration at purchase—no runtime reconfiguration available.

The 7-inch touchscreen renders clearly and supports custom backgrounds and menu layout per manufacturer documentation (Datasheet 2024, p. 3). For shifting user populations such as hotel guests in breakfast areas, this guards against operator error. Beverage selection remains hardware-limited: only fitted product hoppers appear as available selections. Dispense height is electronically controlled, spanning 75 to 170 mm (German Datasheet L543D0, p. 3), restricting deployment at niche sites like grab-coffee services requiring oversized cups.

Milk delivery employs Necta's Milk PerFoamer system, sourcing fresh milk from external refrigeration units with separate temperature control. Connection to external refrigerators is mandatory; no built-in cooling exists (Datasheet 2024, p. 2, 4). Fresh-milk dispensing succeeds or fails entirely with this peripheral. A lockout function blocks milk delivery after shift-end if cleaning has not occurred—operator errors are thus trapped at the machine, though incomplete cleaning cycles remain unguarded.

Connectivity ships standard as WiFi and Bluetooth, documented in both datasheet and user manual. Telemetry is used for remote service alerting; complex remote steering or configuration changes over the internet are not implemented per available sources (Datasheet 2024, p. 4, German Datasheet L543D0, p. 2). Analogue logging, full-automatic inventory capture or alarm functions are absent. For operators without in-house support, this means: no complete remote operation, but at least status reporting and baseline data for service visits.

Payment is restricted to an optional MDB board with coin module and change-dispensing function (Original Manual H5035EN01, p. 65, 68–70, 88). Card or mobile payment are not factory options. Retrofit of cashless solutions remains the operator's responsibility and requires cost outlays plus mandatory coordination with equipment partners on protocol and interface grounds.

Two bean hoppers at 1.2 kg each—for many operators, this sets the ceiling. Capacity supports roughly 200 beverages daily per the official German datasheet; current international manufacturer specs cite comparable hopper and output figures without explicit cup count. Chocolate powder holds 1.8 kg per 2024 datasheet; barley instant allows 0.5 kg, milk powder up to 0.75 kg. The machine targets sites with sustained high demand, not typical office coffee setups for ten staff. Throughput under 100 cups pushes capital and fixed costs upward without benefit.

Whether office corridor, hotel breakfast area or canteen alcove: configurations scale freely between one and two espresso mills (ES), one or two instant containers (IN) and fresh-milk system. This is a purchase-time programming exercise, not a runtime operator function. Touchscreen menu logic permits ten direct selections per page with undocumented unlimited pages per German manufacturer spec. Distinct beverages—coffee, cappuccino, chocolate, espresso, optional barley coffee—deploy across near-arbitrary assortment breadth.

Daily output is widely specified by the manufacturer as 200 cups; distributor sites sometimes cite 250 cups/day without primary source reference. Operator accounts report realistic throughputs of 90 to 150 beverages per machine in office routine without stress. Dual-bean and instant configurations are mandatory at higher demand. The limiting factor often becomes fresh-milk refrigerator refill cycles and brew-group service intervals. By 150–180 cups/day, technically mandated maintenance engages every 2–3 months. At venues with sudden guest surges—breakfast hotels between 6:30 and 9:30 am—pre-service verification of all hoppers and grounds bin reserves is essential.

Small sites and decentralized branches are oversized by the Kalea Plus. The breadth of drink recipes and heavy fresh-milk focus justify investment only at meaningful utilization thresholds. Parallel regular and decaf coffee delivery via dual-mill configuration genuinely offers two bean types concurrently. The constraint: no reliable published volumes for filter coffee or cups exceeding 270 ml from either manufacturer or operators.

Bean-coffee plus instant-module combinations enable hybrid specialities; drink customization is bounded by programmed variants. Simple selection sequences are possible; spontaneous modifications such as swapping bean origin mid-dispensing are not available. Mid-tier large machines reveal: 200-cup/day capacity is the operative mark for operations of 60–120 staff, hotel breakfasts and small canteens. Single offices or sites below 30 daily drinks lack economic justification, leaving assortment potential untapped.

Daily mandatory routine: the automatic milk-system cleaning cycle runs after hours, requiring 5 to 8 minutes per manual. Insert cleaning tablet; the system executes autonomously. Without this step, the display blocks all milk beverages for the next day. Drip tray emptying and grounds bin removal belong to end-of-shift, as does outlet-area wiping. Manufacturer quotes 8 minutes total for complete daily cleaning, with milk-system work dominant. Above 100 milk drinks daily, Necta recommends running the program twice. Weekly, mixer and milk tubing warrant manual disassembly and sanitizing (roughly 20 minutes per manual).

Brew group and seals demand more attention than many peers. After each shift, the display prompts the brew-group wash (powder tablet plus rinse cycle). This is mandatory; skip it and coffee dispensing locks. Z4000 brew-group service falls due every 10,000 vends or six months, whichever comes first (see Manual p. 28–29). At 150 cups daily, service is thus due every 2–3 months. Seal-kit pricing ranges 5–15 EUR per spare-parts retailer; a complete replacement brew group stands at roughly 475–601 EUR plus labour (Gerds-Coffeehome.de).

Typical wear items like flow-meter sensors are individually stocked at approximately 94 EUR (Kaffeetechnik-Shop.de), with turnaround typically 1–3 working days. Self-service on these tasks saves the technician callout of roughly 80–120 EUR per visit. In practice, this is only economical with in-house workshop capacity or under service-contract arrangement. Deeper interventions like boiler descaling and hydraulic repairs are technician-reserved per manual; precise hourly rates and maintenance contract pricing are not publicly disclosed by Evoca or authorized partners such as ATW-Technik (atwtechnik.de/evoca-kundendienst/). No public fixed-price offering exists; operators must negotiate individually.

Service coverage is dense. Kalea Plus parts stock in Germany from at least three major distributors (Liberty Vertriebs GmbH, Gerds-Coffeehome.de, Kaffeetechnik-Shop.de) with typical 1–3 day lead times (Libertyshop.de). The Z4000 platform shares components across other Necta and Wittenborg lines, reducing downtime when standard parts suffice. Technician-only work is required for heating-system or boiler-descaling interventions.

Any missed mandatory cleaning triggers immediate menu lockouts. Flow-meter and "brew-group cleaning" faults are the most frequently cited error messages in operator forums (Kaffee-Netz). One operator documents concrete surcharge costs on same-day parts purchase plus quick recovery after replacement.

Used-machine buyers should demand clear maintenance records. Undocumented service history or aged password protection carry risk of unplanned downtime and extra technician costs. A maintenance contract is strongly recommended for mid to high throughput sites, since unscheduled service visits otherwise rapidly exceed budget.

3,200 W peak draw. The Kalea Plus clearly sits in the high-power class for office and foodservice machines. The manufacturer specifies exactly 3,200 W peak at full load (source: Evoca Group Technical Datasheet 2024, p. 4), requiring a 230/240 V circuit at 15 A minimum. Single-phase, but not typical office-outlet consumption—operators must verify electrical supply and circuit protection. Beyond the scope of small tea kitchens.

Standby draw is differentiated in the user guide: espresso-only variant consumes 1,171 Wh per 24 hours; the Plus configuration with steam reaches roughly 2,400 Wh (source: Evoca Manual H5035EN01, p. 31). This translates to annual consumption of approximately 428 kWh (espresso only) to 876 kWh (espresso plus steam) on a full-day standby basis. Operators using Deep Sleep mode can schedule windows with reduced water temperature to cut standby loss; no concrete savings values are published. Cold-start warm-up to operating temperature requires 63 Wh for the standard configuration and 173.7 Wh including steam boiler. Time-to-ready in seconds or minutes is absent from the datasheet—operators must test per installation.

No sound-pressure data appears in any published primary document. Operator reports and forum posts remain silent on noise. Sensitive areas such as libraries or executive suites require pre-deployment trial.

Energy efficiency rating is not disclosed. Ecodesign metrics are entirely absent. Given 3,200 W connection rating, integration into building energy-monitoring workflows is advisable. At 200–250 daily outputs realistic for this model, the high base consumption spreads across many drinks. Under 60 daily cups in small operations, energy cost per beverage becomes significantly higher than at high-volume sites. Calculation must account for total context: power tariff, operating hours and actual utilization.

Direct-cooled milk systems and auxiliary refrigerators draw additional current. Datasheet figures do not address this. Heavy cleaning cycles or extended idle periods demand on-site empirical data—no published benchmarks exist from the maker. Operational deployment requires advance consultation with electrical specialists.

Net prices for the Necta Kalea Plus range 6,798.32 to 9,439.20 EUR by current quotes from Munich Coffee Company and ECM SanRemo. The black variant prices near 7,201 EUR net. Used display stock pieces trade below this, though service records and meter readings remain uncertain. Lease or instalment schemes exist in market at 150–250 EUR monthly on 3–5 year terms; all terms require individual negotiation. Not included in purchase price: refrigerator, installation, maintenance, water filter and consumables. Buyers should define all options pre-order and confirm in writing (see Munich Coffee Company – Kalea Plus 2 Mühlen + 1 Instant and ECM SanRemo – Kalea Plus 2ES + IN FM).

Sample 5-year total-cost calculation, 150 daily cups (37,500/year): Purchase price (midrange): ~8,120 EUR net. Installation/water filter/initial training: flat 800 EUR. Brew-group maintenance every 10,000 vends or 6 months: minimum 5–15 EUR seal-kit plus technician (~80–120 EUR hourly, frequency at 150 cups/day roughly every 2–3 months, details Kaffee-Netz – Kalea Plus Volumenzähler). Milk-system and brew-group cleaning tablets: 0.26 to 0.60 EUR/unit (current gross pricing hotcoffee.de). Replacement parts such as flow meter (~94 EUR/unit), brew group (475–601 EUR; Gerds-Coffeehome.de – Ersatzteile Necta Kalea Plus verifizierte Preise). Power draw (3,200 W peak, espresso standby 1,171 Wh/24 h, espresso + steam 2,400 Wh/24 h per manual, Evoca Kalea/Kalea Plus Originalanleitung – Seitenansicht). At assumed 13 cents/kWh and realistic usage, annual energy cost runs roughly 111–228 EUR.

Over five years, operator-only costs (excluding beans, milk and unplanned service) quickly total 10,000–13,500 EUR. This yields 13–18 cents fixed cost per drink for machine operation and maintenance alone, depending on utilization intensity. Raw materials such as beans and milk add individually per venue, café or hotel standard.

Drivers of running cost are cyclical maintenance (brew group, valves, seals), milk-system cleaning programs and quality-sensitive parts like flow meters. Boiler descaling falls outside user scope and generates unbudgeted technician charges. Used-machine purchases without maintenance documentation carry risk. After 5 years and 200,000 vends, unserviced machines may exit economic operation. Low-throughput deployment multiplies per-cup cost disproportionately. This calculation reflects 2026 baseline; spare-parts pricing may spike (all pricing and details: Munich Coffee Company – Kalea Plus 2 Mühlen + 1 Instant, ECM SanRemo – Kalea Plus 2ES + IN FM, Gerds-Coffeehome.de – Ersatzteile Necta Kalea Plus verifizierte Preise, Kaffee-Netz – Kalea Plus Volumenzähler).
