Our Products
Leading Manufacturer, Supplier & Retailer of Bulk Liquid Oxygen Tanks.
The vacuum-insulated double wall tanks consist of two concentric vessels, an austenitic steel inner tank and an outer jacket in carbon steel with an anti-corrosion primer and a special environmentally friendly top coat. The interspace between inner and outer tank is evacuated and filled with insulating powder (perlite). An adsorbent is also added to maintain the vacuum in the insulation interspace.
The standard tanks come in gross nominal water capacities from 3, 160 litre to 61, 620 litre. The maximum allowable working pressure for these tanks is 18, 22 or 36 bar gauge for design temperatures ranking from -196C up to 20C. All standard tanks have vertical configuration, requiring little space for installation. The pressure vessels are manufactured and tested in accordance with the Pressure Equipment Directive EU 97/23/EC and EN 13458. These codes are internationally accepted. Consequently, it will be much easier than before to install and use these tanks in and outside of the European Union.
The quality management system satisfies all elements of the ISO 9001 program. All produced tanks are subjected to inspection and quality control under supervision of independent inspection bodies.
The operating pressure may be set up to 90 % of the maximum allowable working pressure and is automatically maintained constant by the regulator and pressure building coil fitted to the tank. Each tank can also be equipped with a tank mounted (clip-on) air-heated vaporizer to supply product in gaseous form at ambient temperatures and flow rates up to 120 Nm3/h. Standard tank features are various fittings for transportation and installation. Vaporizers up to 1, 000 Nm3/h are installed separately.
Based on the standard design, we offers additional features depending on clients requirements.
Standard carbon dioxide tanks are very similar to the tanks for air gases. As a function of the application and customers request you have here the choice between an inner vessel either manufactured from a low temperature resistant austenitic steel or a fine grain carbon steel. The insulation system is equal to the system which is used for the air gas tanks.
CO2-tanks, equipped with an inner vessel made out of a low temperature resistant austenitic steel can therefore also be used as multi-purpose storage for other industrial gases. Owns long standing experience in hand-ling other liquefied gases such as for example LNG and hydrogen. Tanks for these gases are engineered and manufactured according to customers specifications.
The vaporizers are suitable for a design overpressure = max. allowable working pressure (PS) of 40 bar and a allowable operating temperature range (TS) of +50/-269C.
Design and testing was carried out in accordance with the directive 97/23/EC concerning pressure equipment, AD 2000-Merkbltter and DIN EN. The connecting flanges are DIN EN compliant.
The Linde finned tubes and connecting flanges are made of aluminium alloy and the seals for-med according to Linde standards. Variations defined by specific order instructions are possible.
The stressing of the materials used, at low temperatures for example, was taken into account during their selection.
