Pure-Aire Z1250 Vacuum Purge Air Dryers Reduce Annual Energy Cost

The Challenge Identifying Energy Waste in a High-Volume Operation

Compressed air demand across the facility continued to grow, while aging air dryers consumed excessive purge air and inflated energy usage. With production running at scale, even minor inefficiencies translated into substantial annual operating costs. Leadership needed clear data to isolate waste and identify improvement opportunities without disrupting daily output.

The Assessment A Roadmap to Savings

A Brabazon-certified auditor conducted a comprehensive two-week compressed air system study as part of a utility-funded energy audit. The evaluation reviewed existing equipment performance, operating patterns, air leaks and purge air consumption. Findings showed a path to major reductions by replacing two existing dryers, installing two Pure-Aire Z1250 Vacuum Purge Air Dryers, adding a 2,560-gallon air storage tank, upgrading to high-efficiency air nozzles and repairing system leaks. Projected savings totaled more than 1.33 million kilowatt-hours annually, with estimated energy cost reductions of $106,500 per year.

The Solution Deploying Cutting-Edge, High-Efficiency Technology

Brabazon replaced legacy dryers consuming roughly 15% purge air with Pure-Aire Z Series Vacuum Purge Air Dryers operating at only 1.7% purge air. The patent-pending design uses a compact, self-contained regeneration pump to remove moisture from the desiccant with minimal energy input. Combined with air storage optimization, leak repair and nozzle upgrades, the system delivered immediate performance improvements across the compressed air network.

The Result Verified Savings Surpass Projections

Following installation, a post-implementation audit confirmed energy savings well beyond original estimates. Verified annual savings reached $131,500, exceeding projected targets by more than $25,000. The customer also received a $71,050 incentive payment from their utility provider, further accelerating project payback and strengthening the overall return on investment.
