L&W STORAGE
Storage Cylinders
Storage tanks are frequently used to provide extra filling capacity during peak periods. The storage cylinders can either be opened all at once“ in a single stage, or cascaded“ into the cylinders to be filled, usually in 3 stages.
- Stationary steel tanks 10 year hydro test, powder coated in accordance with EN 1089/3
- Powder coated according to EN 1089/3
- Special paintings on request
- 50 l tank size
- Operation pressure: up to 350 bar (200, 300, 420 and 500 bar on request)
- Painted steel housing (RAL 6026)
- Connected according to customer’s specifications
- Modular construction to accommodate future expansions

Storage Management
Single stage storage management
High pressure valve and pressure gauge can be installed as a storage controll in every L&W filling panel.
Cascade panels
Cascade filling panels are efficient for filling operations without using the compressor (i.e. during silent periods). The separate panels can easiely be without any difficulty added to an existing filling station.
- Steel frame and housing, powder coated in RAL 6026
- Available in 1, 2, 3 or 4 stage versions
- Ø 63 mm 0-400 bar glycerine filled pressure gauge for each stage
- Hand wheel isolation valve for each stage
- 8 mm bulkhead fittings (left), 1 for each stage and 1 for the compressor
- 8 mm bulkhead fitting (right) outlet to the filling panel
- Ready to connect, fully piped with stainless steel piping

Auto Filling Selector
The compressor, storage and auto filling selector can be located remotely from the filling panel with only one HP line between the auto filling selector and the filling panel.
Cascade filling panels are efficient for filling operations without using the compressor (i.e. during silent periods). The separate panels can easiely be without any difficulty added to an existing filling station.
The auto filling selectors are available in 3 versions:
For applications with a storage pressure of min. 300 bar and a max. filling pressure of 225 bar.
300 x 270 x 100 mm, 3 kg
For applications with a storage pressure of min. 300 bar and a max. filling pressure of 225 bar. The outlet pressure is set by the pressure reducing station and is secured by the downstream safety valve.
550 x 350 x 150 mm, 9 kg
Switching points can be exactly set by the electronic pressure transducer. This system has to be used when the filling pressure is close to the storage pressure, e.g. storage pressure of 330 bar and filling pressure of 320 bar.
430 x 500 x 200 mm, 16 kg
Options: Auto start signal for the compressor
Pressure Reducing Stations
Ideal for safely reducing storage pressure down to the required filling pressure. The pressure reducing stations are available with various inlet and outlet pressures and high flows for large capacity applications.
