CO₂ Flow Meters & Regulators – Dial in Accuracy

For precise gas delivery, you need a high-performance flow meter or regulator designed to maintain consistent CO₂ flow rates. Our selection includes:  
Single-stage and dual-stage regulators for stable pressure control.  
Flow meters with easy-to-read scales for accurate gas monitoring.  
Preset and adjustable models to match your exact requirements.  
High-flow options for industrial applications, minimizing pressure drops.  

CO₂ Gas Heaters – Prevent Freezing, Maximize Flow

Running high-flow CO₂? You’ve probably experienced freezing at the regulator, which can disrupt operations and damage equipment. Our CO₂ gas heaters prevent this by warming the gas before it hits your system, ensuring consistent performance, reduced pressure fluctuations, and improved gas flow stability.  

Inline and regulator-mounted heaters for seamless integration.  
Prevents regulator freeze-ups at high flow rates.  
Maintains optimal CO₂ performance across all applications.
