- Heart of the vending machine- Data transport

- coin recognition- motor drive- temperature

- Different types: lead, diameter- 360° turn: 1 product- 1 motor per (set of)coil(s)- No friction: negligible power- Stainless steel

Danfoss 4550

- ±15°C (zones)- Air circulation, insulation PU- Compressor, expansion valve, refrigerant,

exchanging pipes

1. Compression of Freon: high-pressure hot gas2. Condensation into liquid, dissipation of heat3. Expansion valve controls amount of freon to evaporate into low-pressure cold gas4. Warmth absorption, back to compressor

ventilation circulation

- Locking system: 3 point lock + lever- Layered glass: PVB + glass (reduction UV radiation and high frequency sound)

- No accces through delivery drawer- Stability: 4 legs M16

- 400 kg- H: 1830 W: 990 D: 880- Power: 670 W- Voltage: 230V- Frequency: 50Hz- Current: 16A- Steel and inox
