Dairy & Wine

Health and safety regulations in the dairy and wine industry are of utmost importance in keeping processes and the finished product free from contaminants. Industrial Air Systems NZ specialises in providing clean and dry compressed air and gas solutions, tailored to suit a wide range of applications within these critical manufacturing processes.

Class-0 oil-free air

Industrial Air Systems Pneutech Oil-Free air compressors are ideal for applications in the food industry. They generate 100%, oil-free air while providing the benefit of low operating and maintenance costs with an efficient rotary screw system. Proven designs and quality engineering ensures the Pneutech oil-free compressors only deliver optimum performance, and arguably the highest reliability, in the oil-free compressed air class.

Air treatment equipment

Just as important as the compressor, are the filtration and drying processes, which serve to remove unwanted water and other contaminants from the compressed air supply.

We understand the particular needs for every different application, and offer a wide range of both standard refrigerated and specialist desiccant compressed air dryers to suit your requirement.

We also offer a wide range of Pneutech industrial filtration for both non-critical, and sterile applications, to facilitate Class 4 to Class 1 grade compressed air.

Nitrogen generators

The majority of winemakers in New Zealand still use bottled nitrogen for their production of wine, however an in-house Nitrogen Generator will bring huge reductions to your gas cost and increase your productivity and quality control no-end.

We at Industrial Air Systems can offer the world-class Pneutech modular generator with the facility to add further modules and capacity to the generator as your business and production increases over time.

The in-house nitrogen generation system brings many additional benefits to cost savings including the below:

• Adjustable and reliable purity control from 95 to 99.99%
• Guaranteed 24/7 delivery,  on-tap.
• Greater quality control by enabling the use of this low-cost N2 gas supply in so many additional applications.
• Time-saving with no bottle handling/downtime
• Safety, with no high pressure gas storage, and no bottle handling

Designed as a very compact, modular system that can be added to as your production requirement increases, the Nitro series N2 generator is second to none, in performance, efficiency, reliability, and low operating costs.

Case Study - Babich Wines

The Babich family has been making wine in New Zealand since 1916. With 12 vineyards spread over the Henderson Valley, Hawkes Bay and Marlborough, Babich values innovation as a key part of their winemaking excellence.

To supply their new production facility, a reliable and cost effective nitrogen gas supply was needed. For their production size and types of operations, ordering bottles as required with the risk of limited supply was not a sustainable or economical option.

The new winery potentially had an increased compressed air requirement as well. The initially installed compressor wasn't the most economical to run. Due to it being fixed speed, it was under-utilised during the off-season and under capacity during vintage.

The solution was to install an in-house Nitrogen generator system so they had a consistently reliable sources of N2 gas available 24/7, 365 days a year. This delivered a much lower cost per metre cubed than bottled or liquid form.

In order to do this, an increased compressed air supply was required. This would involve installing a larger variable speed compressor that operated to match varying air demand. This would bring energy savings, having only to pay for the compressed air used.

After looking at several options, Babich decided to go with Industrial Air Systems NZ and their Pneutech brand. We designed, supplied and installed the complete Pneutech nitrogen plant, comprising of a 55kW VSD screw compressor, a standalone refrigerated dryer, a 4/stage auto draining filtration, a PN2 Nitrogen Generator (40M3/hr at 99.9% purity) and storage vessels.

We had a very short time frame to have the plant supplied and completely operational but we managed to deliver it ahead of schedule. To date the Pneutech compressed air and nitrogen plant has operated faultlessly, delivering consistent and quality gas even during high demand use.

We also service this low-maintenance plant from our Christchurch base. We also have a 24/7 local call-out service assurance if it's ever required.

Babich are happy to recommend Industrial Air Systems NZ and their Pneutech compressed air and Nitrogen plant installation.
