Cellarstream Flat to Perfect, Pint after Pint!

Regulation of dissolved gas is essential for breweries and establishments dispensing all types of beers in order to achieve the optimum amount of head and maintain the quality and taste of their beers. To infuse nitrogen into beer at dispense, use the (CS-1) Cellarstream I.

BENEFITS:
• Automatically adjusts dissolved gas levels to where you want them
• Delivers perfect presentation, pint after pint
• Gives independent control over both dissolved CO₂ and N₂. CS-1 takes still beer from the brite tank or keg and dissolves nitrogen and CO₂ into the beer, in-line, on the way to the tap. The CELLARSTREAM Dispense system has a small foot print 8"H x 22"L x 9" D. The unit allows full correction during dispense of both nitrogenation and carbonation from initially flat beer. The calibration system operates by producing a constant stream of water containing a known and displayed amount of dissolved gas. The amount of gas is controlled by gas/liquid membranes. These establish an equilibrium between the gas and the liquid in terms of the amount of the dissolved gas in the liquid which is purely a function of temperature and pressure. The process merely requires a mixed gas source with 25% to 30% CO₂. The unit is designed to be installed in-line prior to the point of dispense and can feed multiple faucets from a "Y" or manifold.

MAINTENANCE IS IMPORTANT. Each Cellarstream purchased comes with 1.9 oz Line Cleaning Powder Packets. This specially formulated line cleaner does not cantain surfactant type chemicals or chlorine based chemicals. It is designed with color change technology to let you know when your lines are totally clean. If the liquid changes from purple to a green or yellow color, it means there are still residual organics hanging around and the lines aren't quite clean yet. Continue to circulate fresh solution until the liquid remains purple after three or more minutes of contact. IMPORTANT: Cleaning with surfactant type chemicals and/or chlorine based chemicals will damage the nitrogenation infuser causing it to become wetted and/or saturated compromising performance and voiding warranty!

ADVANTAGES OF CLEANING PACKETS:
• Cleaning packets are safe and encompass exact dosing.
• Chemical utilizes a fast to read color changing technology.
• Chemical is fast rinsing.
• Chemical is chlorine free
• Chemical dissolves yeasts, sugars and other organic residues.
• Cleaning Packets last up to 5 years in storage.

IMPORTANT INFORMATION: Cellarstream should always have gas supply feeding the membrane even when not in use unless it has been purged of all liquid. While not in use the beer pump gas feed should be disconnected from bottom of beer pump.

Beer should have low carbonation level around 1 to 1.5 volumes of CO2.

Supply Gas Should Be 75% N2 / 25% CO₂ and primary gas feed to Cellarstream should be min of 10 psi higher than regulator setting on the Cellarstream.

Liquid line cleaning chemicals should only be utilized for cleaning to prevent damage to membrane.

IMPORTANT: Surfactant type chemicals (ie BDP, DraftTech, Micromatic DraftLine ect) and/or chemicals with chlorine will damage the Cellarstream membrane causing the membrane to become wetted and/or saturated compromising performance.

Flow rate should be controlled by instructing servers to pour one pint and then shut faucet momentarily allowing membrane to become enriched with gas. A maximum of 32 Oz can flow across membrane before over-running the gas content in membrane. By pouring a pint and closing faucet for just a moment will prevent inconsistent pours. The process of line cleaning should be performed in a similar manner to assure beer is at proper gas level when complete with line cleaning.

In the event of problems from non gas exchange from membrane it's important to check that mixed gas supply has not been depleted or shut off. If only liquid pressure is applied to membrane without equal gas pressure on internal side of membrane it will become liquid logged. This will result in "flat" beer and will need to be dried out using the following process:

1. Flush line with water using beer pump to pull water from a bucket and allow water to flow from faucet until clear
2. Disconnect gas inlet fitting from beer pump
3. Adjust Cellarstream regulator to 45 - 48 psi
4. Connect CO2, N2, Or Mixed Gas to the product inlet of Cellarstream line which is the Beer Pump Product inlet. (Adjust pressure to 30 - 40 psi)
5. Open outlet of Cellarstream at shut-off in cooler or open faucet at bar and allow all water to purge from Cellarstream & line. (Objective is to blow system clear of all moisture)
6. Repeat process of opening the outlet of faucet to purge residual moisture which may take 8 hours to 48 hours depending on each case (when expelling moisture from the line only leave shut-off or faucet open for about 5 seconds, then repeat after pressure builds) Once there is no moisture in system the membrane will be able to perform its function of liquid gas contactor. The primary objective with the Cellarstream is to allow liquid pressure and gas pressure to be in equilibrium. This is why the regulator on Cellarstream has it's outlet split feeding both the beer pump and the membrane. Liquid feed which is generally beer should be at a lower pressure than the regulator setting on the Cellarstream. Normally the beer feed pressure will be around 10 – 12 psi. and the Cellarstream regulator is adjusted to 26 - 40 psi.

VERY IMPORTANT NOTE: Shurflo Beer Pump is the only pump that can be used on the Cellarstream as it does not create cumulative add to the liquid pressure feeding the membrane! If a Flojet Beer Pump were to be used the liquid supply pressure would be combined with the Cellarstream regulator pressure setting and would cause liquid pressure on membrane to be greater than the gas feed side thus causing the membrane to become liquid logged!
