Since over fifty years NINNELT

International (Salzgitter) is an

established manufacturer and

supplier of complete filling

stations for liquefied gases, such

as propane/butane, ammonia,

carbon dioxide, chlorine,

refrigerating agents and others

Dear customers!

Ninnelt filling stations are manufactured since several decades and are in constant use. Our activity area amounts from Scandinavia to the Pacific Ocean.

We have learned your needs and work hard to develop the latest technical solutions for you. Especially in the last 5 years we have presented with a very effective, newly formed team a number of technical innovations on the LPG market.

To the new novelties belong Ninnelt filling equipment with electronic wireless data transmission, re-designed conveyor systems, safety equipment. We design and build facilities that will meet all customer requirements. You can be sure that everything that is necessary for you to be successful in your business, can be realized by us. Also, the filling stations abroad are made in consideration of the relevant legislation.

We want to emphasize that the development and production take place exclusively in Germany.

My colleagues and I are very happy to put our ability for your benefit to the test.

Your Artur Pohl

Inline Filling StationsInline Filling Stations with driven chain convey-ors are designed for an average filling perform-ance. Depending on the size of the bottles are mounted up to 5-6 filling scales in a row.

Such stations are designed so that the filling equipment can be operated by one person.

Bottles conveyance to the filling device and fur-ther transport to the test and control units is au-tomatic.

The chain conveyor rails, drive and turn-over sta-tions are sunk in the ground for the filling of big bottles. For small bottles the stations are installed on the ground and the chain conveyor rails are suspended.

The complete filling and test sequence is opti-mized by means of a pneumatically controlled equipment. The installation of all filling devic-es listed in our program is available in an inline filling station with an additional mounting of a lift bridge.

Roller Conveyor StationsThe use of roller conveyors is intended for filling stations with irregularly arriving to be filled cylinders. The roller conveyor is the easi-est means to transport bottles. If the roller conveyor positioned with a down-grade of 2-3%, the cylinder rolls freely after a slight push on the ball-bearing steel rollers.

The roller conveyors are suspended to achieve a user-friendly working height. The installation of all filling devices listed in our program is in a roll-er conveyor station available.

For the filling and check devices the roller con-veyor is interrupted. The operator has to pull here the gas cylinder from the roller conveyor to the filling device or the check unit.

Compact UnitCompact Units are designated as Ninnelt products which fulfill several tasks and mounted on one frame. It works as one unit with different tasks.

In a compact filling station as a protective cabinet are inserted a filling unit and a evacuation rack with a hand pump in a closed cabinet.

Overfilled or leaking gas cylinders can be emptied into another cylinder, or in a gas tank.

Here are the different combinations of filling equipment, filling connections and evacuation units available, depending on customer require-ments.

This structure can also be extended still, e. g. with a pump, tanks, decanting equipment.

Accessories: Leak Testing Units The Leak Testing Unit checks the tightness of the cylinder valve after filling. It is also a visu-al water check of the total cylinder through an immersion bath possible.

The tightness of the cylinder valve can be exam-ined visually or electronically. During visual in-spection a Plexiglas bell is placed over the cylin-der valve. With opening of the valve, water flows into the bell. If bubbles are formed the leaky cyl-inder valve must be replaced. Through raising the checking bell the water flows off over the cylinder. By the manual electronic check the testing bell is placed manually over the cylinder valve.

The gas in the testing bell after the actuation of a key is extracted and the gas concentration in the air flow is detected by a gas sensor. If the gas con-centration is too high you will see a visual signal.

With the automatic electronic leak testing there is no personnel required. The gas cylinders to be tested — suitable for different bottle heights — are transported by the chain conveyor to the de-vice. Here the cylinder is centered and the testing bell moves automatically onto the cylinder valve, the gas measurement is initiated.

Leaky bottles are pushed over a pneumatic expul-sion on a roller conveyor. The control is pneumat-ic and built in a switchgear cabinet.

Accessories: EEvacuation UnitsWith an Evacuation Unit faulty filled or leak-ing gas cylinders can be emptied in a simple manner. The discharged medium is pumped into a storage tank.

An evacuation unit consists of a sturdy steel frame, which for one or more cylinders is de-signed. In this frame, the gas cylinders are manu-ally inserted upside down.

Heavy big bottles can be placed on a tilting device which is placed at ground level, and the rotation occurs via a hand wheel or lever.

The unit can be equipped for different gas cyl-inder valves with appropriate discharge connec-tions. The evacuation of several gas cylinders can be performed simultaneously. Are the gas cylin-ders emptied, the discharge process is terminat-ed by means of an automatic switch off. Alterna-tively, upon reaching a minimum pressure, which can be read on the manometer, shutdown can be made by hand.

For exhaustion are used pneumatic driven pumps. If only a few gas cylinders are to be evacuated, a hand pump can be installed. Special solutions are possible.

10



Accessories: Filling DevicesWith our filling equipment all types of gas cylinders can be filled. For the different cylin-der valves, a number of filling connections are available. We differ in filling devices the me-chanical and the electronic type series.

The shutdown of liquid gas supply reaching of the adjusted weight can be done with mechanical fill-ing equipment type WAB in two ways.

In the mechanical shutoff no additional power source is needed. The filling device is ready for use immediately after installation and connecting the liquid gas pipeline. In type WAB with pneu-matic shutoff an additional compressed air supply is necessary.

Calibratable electronic filling devices are operat-ed over a digital indicator. This indicator is a pro-prietary development of Ninnelt and is equipped with a module for wireless data transmission. Our check scales are equipped with this digital indica-tor too.

The filling devices are equipped with an exten-sive range of accessories to the respective require-ments.

11



Accessories: Shrinking MachinesTo avoid the fraudulent use of the filled gas cylinders, we have developed a device which seal a shrink sleeve on the cylinder valve. .

The cylinder valve is sealed directly after filling with shrink sleeves. Each shrink sleeve is placed manually over the cylinder valve.

When the automatic shrinking machines type AS, the bottle is positioned by means of a centering device and the correct position of the bottle dur-ing the shrinkage process is on hold. Centering is also suitable for different bottle heights.

Here goes the shrinking bell automatically onto the cylinder valve and the hot escaping air shrinks the sleeve. After the shrinkage is the automatic bottle changeover. The control is pneumatic and built in a switchgear cabinet.

With the manual shrinking devices type MS, the shrinking bell is placed manually onto the cylin-der valve. These devices can be combined with a check weighing on one workplace.

Over the hand-operated telescopic arm with pneumatic weight balancer are simultaneous-ly transported several gas cylinders.

The bottles are held through a vacuum at the gripper arm. This is held in suspension and al-lows easy positioning of the cylinders without operating any controls keys. This simplifies and speeds up the unloading and loading of pallets and pallet cages.
