Why is there different coloured pipe in Pub Cellars?
The different coloured pipe in “Pub Cellars” relate mainly to the gas systems (the soft drink companies have used black for water).
The idea is so you can quickly identify which gas goes where.
There are five main colours:
- Grey (Co2),
- Green (30/70 mixed gas),
- Purple(50/50 mixed gas), 50/50 should be purple but in most cellars white is used.
- White (60/40),
- Blue (air from the air compressor).
e.g. Mixed gasses 30/70 relates to ( 30% Co2 / 70% Nitrogen ) in that order.
