The first centralised Quincy Vacuum System in New Zealand

What is the idea of circular economy and continuous remanufacturing? When a customer wants to keep their plant running, they quite often consider the re manufacturing of assets. In some cases it might make more sense to refurbish the existing asset, even if the cost of a new machine is the same as the re manufacturing cost. It sounds strange, but it is often the case. Why so? Because the cost of the re manufacturing is mainly comprised of the local labour as opposed to material, energy, transport cost and sales margin for a new asset. Hence the environmental impact is lower, local social contribution is higher and expected monetary value equal.

Though thinking about an upgrade, one should not only consider “incurred” monetary and environmental costs, but most importantly to look into economic and environmental values expected in the future. When a new technology brings energy efficiency, even the most cost efficient remanufacturing will result in opportunity cost.

For the last few years Ash Air has been offering Quincy centralised vacuum systems in New Zealand. One step at a time, in a market when re manufacturing and refurbishing is typically the first choice before replacing, we are seeing more companies switch over to this new system. 

Here at Ash Air, we have seen vacuum pumps made many decades ago, underwent multiple refurbishments and are still running. This doesn’t come as a surprise - one of the most well spread types of vacuum pumps - vane pumps haven’t changed much since decades, offering little reasons for upgrade.

But the time has come. With introduction of the Quincy QSV centralised vacuum system on a meat packing plant, we managed to replace 52 kW of installed power by 30kW Quincy QSV. Quincy screw pump is driven by VSD and runs on average at 80% load, consuming about 24 kW. With the new system we expect to save up to 90,000 kWh per year. On top of that we are aiming at recuperating 10kW of heat . We can heat water to 80C, which can be directly used for sterilization processes. This has a saving potential up to 60,000 kWh per annum.

Additional benefits are stable vacuum level and longer service life time of the pumps. And this is just a beginning, we are now standing in front of the technology gap, ready to jump over and progress towards full adoption of a new energy efficient technology.
