Avelair has recently designed and installed an in house nitrogen generation system for a well-known brewery in Southwold, Suffolk. The project provides a highly efficient, sustainable, and cost-effective way to produce nitrogen on site – eliminating the need for bulk deliveries while ensuring consistent gas purity and availability for the brewery’s production processes.

Efficient British-Built Air Compressor

At the core of this installation is a British-built Avelair VSD 30 variable speed compressor, providing the compressed air supply for the nitrogen generation system. Using variable speed drive technology, the compressor automatically adjusts its motor speed to match demand, delivering excellent energy efficiency and significantly reducing electricity consumption.

The system includes a desiccant dryer with two-stage filtration, achieving ISO 8573-1 Class 1.2.1 air quality. This ensures clean, dry, and oil-free compressed air – essential for the reliability and longevity of the nitrogen generator. The purified air then feeds into an advanced PSA nitrogen generator, producing nitrogen at 99.999% purity.

This fully integrated setup creates a robust, high-performance in house nitrogen generation system tailored to the brewery’s operations.

Why Breweries Use Nitrogen

Nitrogen is vital throughout the brewing and packaging process. It is used to:

• Blanket and purge tanks and kegs to prevent oxidation.

• Maintain product freshness by displacing oxygen during bottling and canning.

• Transfer beer under pressure without using CO₂, preserving flavour and consistency.

• Clean and purge pipelines, ensuring hygienic and efficient production cycles.

By switching to an in house nitrogen generation system, the brewery can now produce nitrogen as and when it’s needed, ensuring complete control over gas purity, pressure, and supply.

Benefits of Producing Nitrogen In House

Installing an in house nitrogen generation system offers numerous benefits for breweries and manufacturers alike:

• Reduced operating costs – Eliminates ongoing rental and delivery charges for bottled or liquid nitrogen.

• Security of supply – Removes dependency on third-party gas deliveries and supply chain uncertainties.

• Environmental sustainability – Significantly lowers CO₂ emissions by cutting out transport and bulk delivery requirements.

• Consistent purity – On-site generation ensures nitrogen quality remains constant, improving product reliability.

• Fast return on investment – The savings in gas costs and energy efficiency provide a quick payback period.

The result is a self-sufficient, environmentally responsible, and cost-effective approach to nitrogen supply – perfectly aligned with the brewery’s sustainability goals.

Efficiency Through Variable Speed Technology

The Avelair VSD 30 variable speed compressor is key to the system’s efficiency. Unlike fixed-speed compressors that run continuously at one speed, variable speed technology adjusts automatically to match real-time air demand.

When production slows, the compressor reduces output and energy use. When demand increases, it speeds up to maintain pressure stability. This intelligent control system can deliver energy savings of up to 35%, reducing both running costs and environmental impact.
