Cellarstream Flat to Perfect, Pint after Pint!
$0.00
Nitrogen is inert and is used to dispense beer, in brewery operations and in packaging. It is economical and an environmentally attractive alternative to CO2.
It is designed for use with all types of beer - keg and cask. The CELLARSTREAM is capable of infusing any gas mixture, you select, into beer - even from initially flat beer.
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.

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.
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:
- Flush line with water using beer pump to pull water from a bucket and allow water to flow from faucet until clear
- Disconnect gas inlet fitting from beer pump
- Adjust Cellarstream regulator to 45 - 48 psi
- 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)
- 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)
- 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!
