20 lb Aluminum CO₂ Cylinder – Siphon Tube, CGA-320, DOT Approved (Liquid Withdrawal)

Brand: General Supply

20 lb Aluminum CO₂ Cylinder – Siphon Tube, CGA-320, DOT Approved (Liquid Withdrawal)

This 20 lb aluminum CO₂ cylinder is built for applications that require liquid withdrawal from a siphon-tube tank. It features a high-strength aluminum body, integrated copper siphon tube, and a CGA-320 valve, making it suitable for cryogenic processing equipment that specifies direct liquid CO₂ feed, as well as general CO₂ service when paired with appropriate controls.

Key Features

• 20 lb CO₂ capacity, shipped empty and ready to be filled with food-grade CO₂

• High-strength 6061-T6 aluminum alloy cylinder for durability with reduced weight compared to steel tanks

• Light gray protective exterior coating to limit surface wear in working environments

• Built-in internal copper siphon tube for liquid CO₂ withdrawal and high utilization of cylinder contents

• CGA-320 valve with external threads, compatible with standard CO₂ connections and regulators where required

• DOT-approved cylinder with current production date and required external markings

• Integrated carry handle for easier movement and handling

Technical Specifications

Recommended Applications

• Cryogenic tumblers, sifters, and extraction equipment that specify:

  • 20 lb liquid-withdrawal CO₂ cylinder

  • Internal siphon tube

  • CGA-320 valve connection

   

• Controlled environment agriculture (CEA) and processing environments where liquid CO₂ is required as a process medium

• Beverage and draft systems (when used with a suitable CO₂ regulator for gas-phase dispensing)

• General industrial or laboratory CO₂ service within the cylinder’s rated pressure and valve specification

Usage & Safety Notes

• This is a liquid-withdrawal (siphon-tube) cylinder. Confirm that your equipment is designed for liquid CO₂ feed before use.

• For cryogenic processing equipment that connects directly to the tank, follow the equipment manufacturer’s instructions for hookup – external gas regulators may not be required or allowed.

• For gas-phase applications (draft systems, enrichment manifolds, etc.), use only with compatible CO₂ regulators rated for cylinder pressure and CGA-320 connections.

• Always secure the cylinder in an upright position during storage, transport, and operation.

• Filling, handling, and installation must follow all compressed gas safety standards and local regulations.
