Liquid Cylinder Accessories – Guide to Choosing the Right One

AC Liquid Cylinders are a key component in laboratories, medical facilities, and industrial environments when it comes to storing and transporting cryogenic liquids such as liquid nitrogen. However, it's only with the right accessories that these specialized containers can reach their full potential.

Whether for safe transport, efficient liquid withdrawal, or precise level measurement – the right equipment not only enhances efficiency but also improves safety in daily operations. In this article, we present the most important accessories for AC Liquid Cylinders and explain when each solution is useful.

Not all AC Liquid Cylinders are factory-equipped with wheels, which makes transporting them without assistance significantly more difficult. The AC Transport Cart offers a reliable and user-friendly solution. It has been specially developed for the safe transport of cylinders without integrated casters.
Its sturdy construction ensures that the cylinder remains securely in place, while the ergonomic design allows for safe and easy maneuvering.

When to use:

• For all AC Liquid Cylinders without integrated wheels
• For internal transport over short or medium distances

For AC Liquid Cylinders with wheels, the square transport trolley is a suitable option. The existing wheels are removed, and the cylinder is mounted securely on the trolley. This solution not only improves stability but also reduces the risk of tipping.

When to use:

• When additional stability is required

Safely withdrawing, transferring, or filling cryogenic liquids requires specially designed hoses. AC withdrawal hoses, available in lengths of 1.2 m and 1.8 m, are tailored for these applications. They are flexible, cold-resistant, and extremely durable – even under intensive use.

When to use:

• For safe withdrawal, filling, or transfer of liquid nitrogen

For especially energy-efficient withdrawal, the vacuum-insulated withdrawal hose is the ideal choice. Thanks to its special insulation, the cold is retained within the hose without frost formation – a real advantage in terms of safety and energy efficiency. Particularly useful for frequent or prolonged use.

When to use:

• To reduce cold loss and prevent frost build-up

Withdrawing liquid nitrogen can sometimes result in uncontrolled splashing. The phase separator reliably prevents this by separating gas from liquid. The result is a safe and controlled withdrawal process without risk to personnel or surroundings.

When to use:

• For safe withdrawal without splash risk

The digital C-Stic SGB level gauge provides accurate, real-time measurement of the liquid level. It is suitable for various gases and requires no external power supply, as it is battery-operated. Two integrated analog outputs also allow for easy integration into existing systems.

When to use:

• For precise monitoring of liquid levels

The factory-installed wheels on many AC Liquid Cylinders are robust, but not always ideal for every type of flooring. The heavy-duty rubber caster set offers smoother operation, higher load capacity, and protects sensitive surfaces.

When to use:

• When transporting on delicate floors
• When high load capacity and smooth movement are required

The Multi Port LWD Set enables simultaneous withdrawal from multiple Liquid Cylinders. This is particularly practical for industrial applications with high consumption rates where uninterrupted supply is essential.

When to use:

• When using multiple cylinders at the same time
• For applications requiring high flow rates

Whether for improved mobility, enhanced safety, or more precise control – with the right accessories, you can get the most out of your AC Liquid Cylinders. Always consider your specific on-site requirements when selecting equipment. We are happy to advise you personally in choosing the right setup.
