CREEKSIDE TAPROOM: State-of-the-Art Green Technology. At Creekside, our beer kegs are actually 50 feet behind our iconic custom copper draft system bar wall…so we also had to design a custom “long draw” beer transmission system that keeps the beer cold, fresh and consistent with every pour. 
We partnered with Green-Air to install a Nitrogen Extractor which separates nitrogen from the ambient air as one of our propellants, and NuCO2 to design a large-scale CO2 system using liquid CO2, which we then turn into vapor/gas CO2, then use a network of four “gas blenders” to combine the Nitrogen and CO2 specific for each type of beer we then push the beer. Keeping the beer cold in our 30 degree beer walk-in (which holds 60 half-barrels of beer, or over 12,000 pints on any given day), each beer travels through 1/4″ NSF food-grade tubes, grouped together with glycol-chilled (at 26 degrees) insulated “trunk lines”…each individual run of 50 feet, plus our custom glycol “artery” looping return system using three Micromatic glycol refrigeration pumps. By “making” our own Nitrogen and using Liquid CO2 instead of gas, we reduce our carbon footprint by cutting weekly air-gas cylinder deliveries from weekly to a single quarterly refill. Additionally, with our precision balance of pressure, gas blend and temperature control, Creekside Taproom has a near zero-waste of product as there is no excess foam to pour-off, giving our customers a perfect pint every time, with no foam waste (which we consider alcohol abuse and literal money going down the drain).
THE MORE YOU KNOW: In the air we breathe and call home, 78% of air is actually NITROGEN. We’re Carbon-based units, taking in the bits of oxygen and exhaling CO2. The less crap we put into the air (excessive CO2 versus the replenishment of Oxygen and other toxic emissions), the better for everyone, but the catastrophic damages done in the past century requires a global shift for the planet’s survival. Serious side effects can occur if the oxygen levels drop outside the safe zone. When oxygen concentrations drop from 19.5 to 16 percent, and you engage in physical activity, your cells fail to receive the oxygen needed to function correctly. Mental functions become impaired and respiration intermittent at oxygen concentrations that drop from 10 to 14 percent; at these levels with any amount of physical activity, the body becomes exhausted. Humans won’t survive with levels at 6 percent or lower. Source: SCIENCING.com
