Engineering Principles & Working Mechanism

Precision gas mixers and blenders mix two or three distinct gases (N2, CO2, O2, Ar) with pinpoint accuracy for modified atmosphere packaging (MAP), thermoforming machines, shielding gas welding, and specialized laser processes. Generating mixtures on-site from single-gas supplies eliminates the exorbitant cost of pre-mixed gas cylinders while providing operational versatility.

Utilizing mechanical proportional mixing valves or electronic mass flow controllers (MFC), these units maintain stable ratios within ±1% precision regardless of line pressure fluctuations. In MAP applications, strict gas ratio compliance is critical to retard bacterial growth and preserve product shelf-life.

At HAVKOM Engineering, we provide supply, installation, calibrated gas analyzer verification, and periodic diaphragm/seal maintenance for Witt and all leading industrial gas blender makes.

Frequently Asked Questions

What are the cost savings of on-site gas mixing versus pre-mixed cylinders?

Pre-mixed specialty gas cylinders carry up to a 300% price premium over bulk pure gases. Mixing pure nitrogen and CO2 on-site typically cuts gas expenditure by 50% to 70%.

What is the most common gas mixture for food packaging (MAP)?

For poultry, cheese, and bakery products, 70% N2 + 30% CO2 is common to inhibit bacterial growth. For fresh red meat, high-oxygen mixtures (80% O2 + 20% CO2) are utilized to retain blooming red color.
