The global wine market has never been more competitive, and customer expectations have never been higher. Facing a world of choice, buyers in the wine industry are increasingly turning to familiar brands for the reassurance of consistent quality, taste and affordability. The challenge for producers is to supply consumers’ favorite wines at the volume and cost required while ensuring that taste, character and enjoyment remain undiluted.
From fermentation to bottling, nitrogen has an important role to play in modern winemaking. Nitrogen is used for purging or blanketing tanks, racking barrels, flushing bottles, and at any point where the wine comes in contact with air.
Benefits of using nitrogen in wine production and processing include:
A cost-effective alternative
On-site generation provides a reliable source of nitrogen at the lowest total cost available. Generating your own nitrogen eliminates the hassles of supplied cylinders, dewars or bulk nitrogen. A nitrogen generator, such as the Parker WineMaker series, produces 98 to 99.9 percent pure, dry nitrogen on-demand and dispels any concerns about lines icing up, running low, or running out of nitrogen. Features include:
Easy installation and operation
Installation is simple: pipe in compressed air and pipe out nitrogen. Just connect a standard compressed air line to the inlet of the generator, connect the outlet to your nitrogen line and the unit is ready for trouble-free operation. The system is designed to operate 24 hours/day, 7 days/week. There is no complicated operating procedure or labor-intensive monitoring involved. Simply select the purity your process requires and set the flow and
within minutes, high purity, dry nitrogen is available. Once the nitrogen generator is installed, the system requires very little maintenance.

Searching for a water chiller for an industrial application?
The use of cold water is very common in industry, as cold water improves productivity, secures industrial processes and reduces costs. There are several methods of creating cold water, but water chillers are increasingly becoming the preferred solution. Primarily because chillers always supply the exact water temperature requested, even with differing ambient conditions and load requests, thus ensuring optimum efficiency.
Chillers, by operating in a closed circuit, continuously reutilize the same water, and thereby avoid unwanted water wastage. Add to this fact that a number of directives have recently emerged to safeguard both the quality of the water being utilized (for health reasons) as well as the discharging of impure water into the ambient (to protect the environment): closed circuit chiller operation greatly simplifies conformance to these regulations. The needs of industry are changing, and a water chiller increasingly satisfies these needs.Hyperchill water chiller with wide product range
The Hyperchill product line offers a wide range of cooling capacities from 1/2 to 50 ton, and a huge variety of options to fit every application. Parker’s ability to easily configure and package these options in a turn-key assembly allows for reduced installation costs and easy start-up.
Common installations: Single process closed loop
About 80% of installations are straightforward, single process, closed loop cooling applications. In such an application the piping is simplistic and flow demands are unchanging. The chiller is sized for worst-case site conditions, the pressure drop is calculated for the piping and the process, and there are few, if any, options required. The standard Hyperchill process water chiller includes a pre-programmed PLC, an electrical cabinet with motor overloads, a refrigeration system, and an internal water system.
The two standard pump sizes are “3 bar” with a nominal head pressure around 40 psi, and “5 bar” with a nominal head pressure around 70 psi. The vast majority of applications use high quality, low noise level, axial fans which are installed as standard on the Hyperchill. There is a large cold-water storage tank built into the chillers which allow the compressor(s) to cycle off when load requirements are low in comparison to the available cooling capacity.
This configuration allows the customer to take advantage of seasonal conditions which increase the efficiency of the refrigeration circuit, thereby reducing electrical consumption. The pre-programmed and integrated controller makes set-up a snap. All the customer needs to do is install piping, supply power, fill the unit, and select the desired outlet water set point. From there, the unit is ready for startup!
Beginning with our 5-ton unit, model PCW060, a variety of additional options are available. For outdoor installations where the units are subject to cold ambient conditions, Parker offers two different low ambient packages. These packages can allow the chiller to operate outdoors in ambient temperatures as low as -4°F (-20°C). For conditions beyond this temperature range, the unit must be installed indoors. In such an application, it may be beneficial for the customer to look at our centrifugal fan option, which allows the user to duct hot exhaust air outside the building during summer. The user can also benefit from such an installation by installing a second exhaust port indoors. This would allow the customer to direct the hot exhaust back into the plant during cold winter months, reclaiming the heat and decreasing the cost of heating the facility.
In addition to the centrifugal fan option, Parker offers two additional condenser options. The “Bio Energy” option includes a corrosion resistant epoxy coating on all of the exposed copper piping. This is an excellent option for Bio Gas or Landfill Gas sites, as well as for installation near coastal waters where the environment may be salty. There is also an option for a water-cooled condenser. This is a great choice for High Ambient conditions or for indoor applications where the customer has an existing cooling tower. The water-cooled condenser option may also be selected when the customer has the desire to reclaim the heat expelled by the chiller. Parker can even quote the water-cooled condenser with special corrosion resistant materials of construction for applications where it is desired to use seawater for cooling.
Parker’s highly knowledgeable Applications Engineers can work with you and your team to select the options required to optimize the chillers for your specific installation. For a full list of available options – including special pumps, remote controls options, special voltages, and more.

In southern California, Mulligan Sales, Inc. blends dry dairy and other food ingredients for makers of baked goods, snack foods and confections. These powdered ingredients typically create high dust levels that tend to absorb moisture in the air, requiring cool, dry in-plant conditions.
Dust collection and constant air conditioning create a challenge
In its powdered ingredients processing facility, Mulligan Sales required both substantial dust collection and constant air conditioning for temperature and humidity control. Running both systems simultaneously was not an option with the company’s existing dust collectors—an external baghouse unit with envelope-type filters and a manual shaker for filter cleaning. The existing system vented outside, returning no air back into the mixing and batch-weighing areas. And because the unit would have extracted conditioned air as well, the air conditioning could only be run when the unit was off and the facility was not blending. Additionally, the facility had limited power available for their dust collection equipment, so a bigger system alone was not the answer.
Mulligan needed a solution to:
A Parker Hannifin representative performed a detailed assessment of Mulligan’s existing equipment, identified its key design inefficiencies and areas in need of dust collection, and considered the company’s potential need for additional processing equipment in the future. The representative then arranged a tour of a successful DustHog® installation at a leading snack food maker’s facility. Impressed with its performance, Mulligan chose to work with Parker.
Parker Hannifin solved Mulligan’s temperature control needs with an external DustHog® SFC 12-3 downward flow cartridge dust collector, customized with a C-3600 Cyclone pre-cleaner for each of the existing large mixer and batch-weighing areas. This achieved measurably more effective, efficient dust collection than the previous baghouse unit. Unlike the former externally vented design, the new SFC system returned clean air into the facility. For further assurance, the system featured an exterior safety filter, as well as a silencer to keep the noise level well under OSHA guidelines. As for system size, Parker Hannifin tailored the design to meet Mulligan’s equipment and airflow goals—as well as the facility’s limited horsepower requirements.
Maintenance was also substantially reduced since the SFC system required far less frequent filter change-outs than the previous baghouse unit. This resulted from the SFC’s patented pulse-jet technology that pulses dust off filters. Parker Hannifin designed this pulse-jet system to clean the full length of the cartridge filter for better, long-lasting performance while allowing the unit to clean the filters during operation. Further, the pulsing is delivered in regulated blasts of air, so fewer pulses are needed, which conserves costly compressed air.
Additional value and future needs addressed
According to Mulligan Sales Plant Manager Byron Tobin, the facility went from having “tremendous dust challenges” to an “85 percent decrease in residual airborne dust.” With no external air discharge, the company also began saving thousands of dollars in state permitting fees, while reinforcing its good-neighbor commitment.
This solution also resolved the challenges of dust collection in conjunction with temperature and humidity control. UAS (now Parker Hannifin) worked with our vision all the way,” Tobin said. He also cited quality details that are yielding added value, including the system’s washable filter cartridges with a spare set for less downtime during change-outs, explosion relief vents for protection, powder-coated finish on the collectors for corrosion resistance and three additional flexible dust collection arms that allow reconfiguration of the processing room equipment for other projects.
To accommodate Mulligan’s future needs, the new system can be expanded. Tobin noted that his facility is initially optimizing 30 to 40 percent of the new system’s capacity, allowing for expansion or reconfiguration to improve productivity at any time.
“We knew we needed to step up. The result is impressive, and we have future capability.”
Byron Tobin, Mulligan Sales Plant Manager

As new markets emerge and off trade consumption increases, the shelf-life of canned and bottled craft beer has become increasingly important.
Brewers of craft beers carefully select and balance the ingredients to generate the unique and distinctive characteristics of their brand. And as competition between breweries heats up - and drinkers become more adventurous in their choices - the range of flavours available is blossoming. Coffee, chocolate, vanilla and even smoky flavours are joining citrus fruits, sours and high-intensity hops in the battle for beer drinkers' palates.
Beer's unique characteristics, which include colour, brightness and taste such as bitterness and sweetness, should remain unaffected by any microbiological stabilization treatment prior to bottling. In a competitive market, it's vital that a brewery's products are protected — and that consumers can enjoy their chosen beer's unique flavours as intended.
Sterile filtration (or cold stabilization) is the final microbial filtration of beer using a microporous membrane to remove yeast and typical spoilage organisms to provide extended shelf life. It's an alternative to the flash pasteurization of beer, which deactivates yeast and spoilage organisms by heat. Flash pasteurization demands higher relative water and energy consumption, therefore making cold stabilization a more appealing process to craft brewers who wish to keep operational expenditure low and reduce their carbon footprint.
The final stabilization of beer by microfiltration has commonly been accepted as a gentler method of stabilization, generating a cleaner, fresher, more natural flavour when compared to flash pasteurization.
A number of independent tests have investigated the effect on the taste of both flash pasteurization and cold stabilization by Parker's BEVPOR microfiltration range.
Cold stabilization as an alternative to flash pasteurization, a brewer's perspective
A trial, conducted by a leading UK brewery, indicated that beer packaged after cold stabilization produced a beer that protected the desirable, crisp and bitter taste profiles when compared to pasteurization in a triangular taste test.
The test, carried out with an experienced taste panel, tested the same batch of beer after cold stabilization and flash pasteurization to identify if the method of stabilization impacted upon the finished product characteristics of the beer. In this case, the data generated helped the brewery to select cold stabilization as their preferred method of microbial stabilization.Protecting shelf-life
The studies performed not only established the immediate characteristic changes of the beer that had been pasteurized, but they also identified that the method of stabilization had an effect upon the beer's characteristics for the duration of the product's shelf-life.
The work identified that cold stabilization through BEVPOR filtration increased the time taken for the beer to display a stale/oxidized characteristic. Not only did the oxidized characteristics take longer to develop in the microfiltered beer, but it was far less pronounced over the 12-month trial.
A second brewery in the south of England conducted a trial looking at flash pasteurization and cold stabilization to determine which method would be used in the bottling of a leading premium ale. The same batch of beer was sent to two different contract packagers, one packaged the beer after flash pasteurization and the other after cold stabilization.
The brewing team commented that microfiltration appeared to be a 'gentle process' which protected the late hoppy characteristic of the ale. As a result of this process, the brewery installed an integral cold stabilization unit utilizing Parker's BEVPOR microfiltration cartridges and fabricated housings.
Choosing the right filter materials
Products from Parker's BEVPOR microfiltration range - such as the BEVPOR BR and BEVPOR PH filter cartridges - utilize a polyethersulfone (PES) membrane which has been carefully selected due to its excellent performance characteristics in beer stabilizing applications.
One of the key performance requirements of the PES membrane was making sure the unique characteristics of the beer were protected while guaranteeing the removal of yeast and typical spoilage organisms.
Microfiltration elements are designed to remove spoilage organisms through size, however, they will also remove other material such as suspended solids, proteins, polysaccharides and colour through adsorption. Depending on the extent of the adsorption, changes to the final characteristics of the beer may be possible.
Studies into the adsorption of head retention protein components during membrane microfiltration were conducted using two commonly used membrane materials: polyetersulphone (PES) and polyamide (PA) for both 0.45 micron and 0.65 micron ratings. Results showed that the membrane material had an effect on the protein content of the filtrate. PES reduced the protein content to a lesser degree than the PA membrane. Micron rating was also shown to affect the adsorption of proteins with 0.65 micron filters having a lesser effect than 0.45 micron filters.
Protecting the unique characteristics of your beer
A further study was carried out in order to demonstrate the low levels of protein adsorption expected with PES membrane compared to other materials used for beer filtration and serves to demonstrate the functional benefits of using PES on a number of levels.
Firstly, due to the lower protein adsorption characteristics of PES, the filtration has a negligible effect on the physical and sensory properties of the first run brew, so qualities such as head retention , colour and taste remain unaffected. Secondly, due to the low adsorption affinity, the PES membrane does not foul as readily as PA and is easily cleaned by clean-in-place processes so the system can be regenerated and used again.
Both of these qualities have been observed by multiple brewers who have reported the associated functional benefits of using BEVPOR filters.
