- History- MEI EC 6000- Dispensing coils- Cooling system- Vandalism
Sielaff Sü 2020
- AD 10-70: Hero of Alexandria, holy water- 1880: London, post-cards- 1897: extra incentives -> slots- 2010:
- news papers, cigarettes, candy, food, drinks, condoms, zoomshops...- cash, credit card payment- 30911 patents

- 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
