Product Specifications

Technical details and manufacturing context for CO₂ Supply System

Definition
The CO₂ Supply System is an integral component of beverage filling machines, responsible for delivering precise amounts of carbon dioxide to carbonate beverages and maintain pressure within the filling system. It ensures consistent carbonation levels and prevents oxidation during the bottling or canning process.
Working Principle
The system typically consists of a CO₂ storage tank, pressure regulators, flow control valves, and distribution lines. It maintains a constant pressure supply to the filling heads, where CO₂ is injected into beverages or used to create a protective atmosphere that displaces oxygen from containers before filling.
Common Materials
Stainless steel, Food-grade polymers, Copper alloys

Unsuitable: Corrosive chemical environments (e.g., chlorine, strong acids)
Sizing Data Required
  • Required CO₂ consumption rate (kg/h or m³/h)
  • Filling machine throughput (bottles/hour)
  • Desired carbonation level (volumes of CO₂)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Corrosion in piping and valves
Cause: Moisture contamination in CO₂ supply leading to carbonic acid formation, which attacks metal components, especially in high-pressure sections and at joints.
Pressure regulator failure
Cause: Contaminant buildup (e.g., oil, particulates) or icing from rapid gas expansion causing diaphragm damage, seat wear, or valve sticking, resulting in inaccurate pressure control or leaks.
Maintenance Indicators
  • Hissing or whistling sounds from valves or fittings indicating gas leaks
  • Frost formation on pipes or regulators suggesting moisture accumulation or blockages
Engineering Tips
  • Install and maintain high-efficiency coalescing filters and desiccant dryers upstream to remove moisture and oil contaminants, preventing corrosion and icing.
  • Implement a routine pressure decay test and ultrasonic leak detection program to identify and address leaks early, reducing stress on components and maintaining system integrity.

Compliance & Manufacturing Standards

Reference Standards
ISO 9809-1:2019 (Gas cylinders - Refillable seamless steel gas cylinders - Design, construction and testing) ANSI/CGA G-6.1:2019 (Carbon Dioxide) DIN 477-1:2016 (Gas cylinders - 10-litre to 150-litre water capacity for compressed, liquefied and dissolved gases - Part 1: Manufacture)
