Complete N2 System for Closed-Top Wine Tank $1050 in stock
Does NOT include N2 cylinder

All components (except gas cylinder) needed to keep wine under N2 blanket. Simply attach the system to 2" TriClamp ferrule on top of tank.

Wine tanks cannot be safely pressurized above ~2 psi. This system permits safe pressurization of wine tanks at ~0.5 psi.

  • N2 Vent
  • Ultra-Low Pressure N2 Regulator---you must use an Ultra-Low Pressure N2 regulator. [Standard N2 regulators cannot operate at the low pressure required.]
  • Valves and Fittings.
    • Push-In valve and fittings for easy setup and gas-tight connections.
    • 2" TriClamp 90° Elbow, two 2" TC clamps and gaskets to connect to 2" TrClamp port on tank.
  • Tubing: Includes 100' of tubing. Cut to desired length.
  • N2 cylinder NOT included---obtain a cylinder from your local gas supply.

Easy to add tanks to the system. One regulator can handle many tanks. One N2 Vent can handle several tanks. Contact us with number of tanks, and distance between tanks, and we can setup complete system. As an example, a complete system for 6 tanks (one regulator and one N2 vent) will be ~$1750. A complete system for 3 tanks is ~$1400.

Ultra-Low Pressure N2 Regulators

These regulators are designed for wine tanks in which the pressure MUST be regulated at very low pressure. Maximum pressure is 3 psi and the pressure can be precisely regulated to 0.3 psi.

Wine tanks are neither fabricated nor certified to withstand pressures in excess of a few psi. Standard single-stage N2 regulators should NEVER be used to pressurize wine tanks because the upper pressure limit is too high. Click here for standard single-stage N2 regulators.

In addition, tanks should have a safety release valve installed. The vent pressure should be 3 psi or less. [Please note that closed top tanks with a two-way air valve are fine because the air valve is a safety release valve.]

Low Pressure N2 Regulator--Tank mount $750

  • Pressure Regulation 0.3-3 psi
  • Attaches directly to N2 (or Argon) cylinder.
  • This is a two stage regulator. The first stage accepts pressure of the cylinder (as high as 3000 psi) and drops the pressure to ~40 psi. The second stage regulates the outlet pressure from 0.3-3 psi.
  • Flow 43 GPM
  • Outlet Valve included.

Regulators must be calibrated in the static phase.
Procedure to calibrate: Close the Outlet valve. Open the N2 cylinder valve. (The pressure reading will be inaccurate.) Open and close the Outlet valve. (The pressure reading is now accurate.)

Dual Scale on Gauge. mbar in red, and mm H2O is outer scale.
70 mbar ~ 1 psi. So typically set pressure to 40-50 mbar for wine tank.
Note that the N2 vent (at left) opens at 1 psi (70 mbar), so you must set the regulator below 70 mbar.

Replacement Gauges
Low Pressure $80

Low Pressure N2 Regulator--Wall mount $1195 in stock

  • 0.3-3 psi
  • Wall mounted. Run feed line directly from N2 (or Argon) cylinder to unit. Two inlets permit operating line and reserve. For large operations, place these units at 50' spacings to ensure proper pressurization along entire line of vessels.
  • This is a two stage regulator. The first stage accepts pressure of the cylinder ( as high as 3000 psi) and drops the pressure to ~40 psi. The second stage regulates the outlet pressure from 0.3-3 psi.
  • Outlet Valve included.
These regulators are intended to be used with Closed Top tanks.

Inflatable Gaskets
Instructions for Assembly of Floating Lid of Variable Capacity Tank

Determining Correct Gasket Size

  1. Measure inside diameter of tank in inches.
  2. Multiply by 2.54
  3. This is diameter in cm
  4. Choose matching diameter from table. [If diameter lies between two sizes, choose the smaller tube.]

Polyurethane gaskets may seem too small. They can stretch at least 10%.
It is easier to inflate (stretch) the gasket prior to putting on the lid.

Inflatable gaskets have 30 day warranty subject to normal use and service.

Pumps for Inflatable Gaskets

Periodic maintenance of pumps.
Remove the valve (black knob in photo) and lubricate orings and end seal.

Please note. Do not overtighten black knob---particularly if it has a teflon tip to make the seal. Teflon "cold-flows". This means it changes shape under pressure. Overtightening will change the shape of the teflon, making it harder to seal in the future.

  • Flow: 100 GPM.
  • Cleaning diameter:13'-20'

Note the correct orientation of the components. It is important that the all components rotate clockwise (as viewed from ends). 1)In top photo, note the position of the central part that spins in the horizontal plane. The two arms make an "S" as viewed from above. 2)See end view of nozzles in photo below. Note position and angle of the nozzles spraying to left and right. Both vertical rotating end units should look like this.

 

 

Maintenance of all spray balls. Lubricate periodically with food grade silicone spray. Be sure to rinse well with water after cleaning. Always lubricate after cleaning.

Pressure and Flow for Spray Balls:

  • Spray balls have a range of pressures/flows over which they operate effectively. The greater the pressure, the less flow is needed to maintain the same cleaning efficiency. However, there is an upper pressure limit. At excessively high pressures, the water turns to mist and is no longer effective.
  • City water pressure is often sufficient for rotating spray balls and barrel cleaning head. For example, our city water pressure is max 75 psi, and can supply 10+ GPM at 30 psi.

Rotating Arm for TriClamp Valve
The original simple Rotating Arm—designed, manufacutred, and introduced to the wine industry by St. Pat's.
Allows you to drain up to 8" above or below the racking valve of the tank. It is also an answer to a tank with only one valve and the lees at the valve height.

  • Change a fixed height valve into a variable height valve
  • Drain tank from up to 8" above or below a racking valve
  • Drain tank from up to 8" above the lowest side wall valve.
  • Fittings to fit 1.5", 2", or 2.5" TriClamp
  • For new tanks or retrofit any tank
  • Simple to operate
  • True Stainless Steel Sanitary Fitting--high polish sanitary fitting designed by St. Pats
  • TC Clamp and Teflon Gasket included

The Rotating Arm is an independent fitting that is inserted between the butterfly valve and the tank ferrule. Prior to draining, loosen the TriClamp clamp slightly, rotate the Arm until the drain tube is above the lees, and retighten the clamp. The drain tube can be placed anywhere between 0" and 8" above or below the racking valve.

To operate: Loosen the clamp just a little to turn the arm. Then open the valve slightly while turning the arm until the juice is clear, and retighten clamp. You can now drain all the wine that is above the lees.
Leave the arm in the horizontal position when not in use to prevent lees from settling into the arm.

Please note there is a reduction in the output with the Rotating Arm in place. Each Triclamp size is effectively reduced by 1/2". For example, the RA250 will have the output of a standard 2" valve.
Please note rotating arms will NOT work on 100 and 150 liter tanks--diameter of these tanks is too small.

We set up the N2 systems in miniature----short lengths of tubing between components. This is to insure it will be very easy to understand how to put the system on your tank(s).

You simply need to replace the short lengths of tubing with appropriate lengths for your arrangement.

The tubing is connected with PUSH-IN FITTINGS. To release, depress the ring and pull out the tubing. Simply push the tubing in to connect.

Regulators must be calibrated in the static phase.

Procedure to calibrate: Close the Outlet valve. Open the N2 cylinder valve. (The pressure reading will be inaccurate.) Open and close the Outlet valve. (The pressure reading is now accurate.)

Dual Scale on Gauge. mbar in red, and mm H2O is outer scale
70 mbar ~ 1 psi. So typically set pressure to 40-50 mbar. Note that the N2 vent opens at 1 psi (70 mbar), so you must set the regulator below 70 mbar.

If you wish to understand how the vent works, I suggest the following.

  1. Put a 2" end cap on the side arm of the N2 vent. You will then have a very simple system of N2 regulator with valve and N2 vent only.
  2. Disconnect the tubing on the outlet side of the valve and calibrate the regulator as described above.
  3. Connect the tubing to the valve. Now adjust pressure slowly up to ~100 mbar. At around 70-80 mbar you will hear the gas escaping thru the top of the vent.
    Back the pressure off to ~50 mbar and it will hold pressure for a very long time--we have demonstrated that a K cylinder (50 L) will last literally 1000 years with this simple arrangement.

Maintenance of the N2 Vent.
The N2 vent has a simple design that will operate flawlessly for a very long time. There are no springs or complicated seals so it is easy to maintain.

  1. Periodically remove the top cover---it is simply a press fit over an oring.
  2. Remove the top seal with red silicone gasket. Clean surfaces and gasket with mild detergent cleaner. Lubricate with any non corrosive lubricant.
  3. To remove the bottom (vacuum) seal. Unthread the top part of the vent.
  4. The bottom seal has long thin rod---remove and clean silicone gasket as above.

Two-stage regulators are intended to be used with Closed Top tanks, but not with Variable Capacity tanks.

The top hatch on closed top tanks can be tightly secured with the rubber gasket and latches. The tank can then be pressurized with N2 and sealed tightly. N2 should not be used with Variable Capacity tanks, aka tanks with Floating lids. The Floating lid with inflatable gasket is not designed to allow the tank to be pressurized. Furthermore, the Floating lid rests directly on the wine, with no headspace, thus negating the need for N2. Ironically, installing a N2 system on a Floating lid tank will almost certainly increase, not decrease, the oxidation of the wine. All N2 cylinders have small amounts of O2. Every time N2 is introduced, a small amount of O2 is also introduced. In a tightly sealed system (such as a Closed Top tank), the amount of N2 needed over time is very small (and thus the amount of O2 is very small). In this case, a nitrogen blanket is certainly useful in protecting the product from oxygen. On the other hand, a Floating Lid tank will not seal tightly under pressure. Thus the N2, and O2, introduced over time is much greater. In the extreme, you will oxidize your wine completely by continuously bubbling N2 through it---because N2 cylinders always contain a small amount of the limiting reagent O2.
