  • Self- Contained Nitrogen Generators for Nitro Iced Coffee -Coffee Beans on background - Parker Industrial Gas Filtration and Generation Division

    Battlegrounds Coffee is a small, community-oriented coffee shop in Haverhill, MA. The owners were challenged to find a more efficient and consistent way to deliver Nitro Coffee to their customers.

     

    Nitro coffee is the new smooth brew

    According to Battlegrounds Coffee, Nitro coffee is the new trend.

    It has a soft smooth mouthfeel. It’s like sipping on a Guinness. It gives the sensation that you’ve added cream to it but you haven’t. It looks fantastic poured and cascading in a glass. Nitrogen gas enhances some of the complex coffee flavors that you find in our blends and roasts at Battlegrounds Coffee. Prior to using the generator, we were using pre-charged food-grade nitrogen tanks.

    Self Contained Nitrogen Generators for Nitro Iced Coffee - Nitrogen tank - Parker Hannifin"Tanks were the most difficult aspect of making and maintaining nitro coffee. The pressure gauges on the regulator were faulty indicating you had more nitrogen that was really left. As owners, we would get calls in the middle of the day saying 'Hey, we are out of nitrogen!'

    For us, it was a hassle getting those tanks refilled. We had to drive to the local welding shop. We change out the tank 3-4 times per week so you had to assure that was done right and that there were no leaks. It wasn’t an efficient system and was becoming a hassle. The supplier was charging more than $50 per tank for food-grade nitrogen so my payback was very quick."

    — Sal DiFranco, Battlegrounds Coffee

     

    Nitrogen Generators with on-board compressors for low flow applications provide safety, savings, and convenience.

    Parker nitrogen generators completely eradicate the danger, inconvenience, and high costs of truck delivered nitrogen. The hassles of changing high-pressure tanks and the routine interruption of nitrogen supply are eliminated. They offer long-term cost stability by eliminating vendor price increases, contract negotiations, long term commitments, transportation issues and hazmat charges.

    Once installed, a continuous supply of high purity nitrogen is available within a few minutes of startup. Nitrogen, unlike CO2, imparts a small bubble that creates an attractive cascade down the side of a glass. More importantly, the small size of the nitrogen bubble creates a smooth, creamy finish on your palate. Consumers report that it is even sweeter than conventional iced coffee.

    Meeting the needs of retail coffee establishments

    Self Contained Nitrogen Generators for Nitro Coffeee - Case Study - glass filled from tap - Parker Industrial Gas Filtration and Generation DivisionBuilding on Parker’s history of over 35 years of producing Nitrogen Generators for beverage dispense, we are pleased to offer a nitrogen gas generator specifically designed to meet the needs of retail coffee establishments. Parker Nitrogen Generators eliminate the danger, inconvenience and high costs of truck delivered nitrogen. There is no need to rely on an outside supplier. The hassles of changing high-pressure tanks and the routine interruption of nitrogen supply is completely eliminated. 

    Parker Nitrogen Generators are also good for the environment because delivered nitrogen is manufactured using an energy-intensive process and then distributed in smog generating trucks. Parker generators offer long term cost stability by eliminated vendor price increases, contract negotiations, long term commitments, tank rental fees, delivery fees and hazmat charges. Once the generator is installed, a continuous supply of high purity nitrogen is available within a few minutes of startup.

    Cold brewed coffee may be enhanced with nitrogenation. Nitrogen becomes infused into the coffee, much like a nitro beer. Nitrogen, unlike CO2, imparts a small bubble that creates an attractive cascade down the side of a glass. More importantly, the small size of the nitrogen bubble creates a smooth, creamy finish in your mouth. Consumers even report that it is sweeter than conventional iced coffee. Imagine the reaction of your customers to a creamy slightly sweet coffee without the need for added cream or sugar! Parker nitrogen generators are ready to operate as delivered with carefully matched components engineered for easy installation, operation and long term reliability. The generators are free-standing and housed in an attractive cabinet with casters.

     

    Operation

    The Parker DN-6NA Nitrogen Generator is designed to provide a constant supply of nitrogen gas, at a pre-selected purity, flow, and pressure. The system uses proven Pressure Swing Adsorption (PSA) technology with a Carbon Molecular Sieve (CMS) to separate N2 from the atmosphere and deliver it at high purity. The installation consists of simply connecting the plug to a standard outlet and connecting the nitrogen outlet to your coffee dispenser.

    The onboard compressor means that there is no need to connect to a source of compressed air. Simply turn it on, and the air is then prefiltered, compressed, and passed through a 0.01 micron filter rated at 99.99%. The air is then passed through the CMS separation bed which captures the oxygen, creating a stream of high purity nitrogen. Lastly, the stream of nitrogen is passed through a sterile grade filter rated at 99.99999+% at 0.01 micron and then sent to the coffee dispenser. The CMS bed is regenerated to remove the captured oxygen and the cycle repeats.

      Nitrogen generator package includes
    • Self Contained Nitrogen Generators for Nitro CoffeeNitrogen generator, filters, controls, and an on-board compressor
    • Floor mount on casters
    • Automatically shuts down if there is no demand
    • Stays in standby mode until more nitrogen is needed
    • Environmentally friendly
    • Compact - frees up floor space
    • Eliminates unexpected shutdowns
    • Hassle-free operation
    •  Safe and reliable
    • UL, NSF, & CE listed
    • CB Scheme, CSA, EMC and IEC certified
     

     

     

     

    Self Contained Nitrogen Generators for Nitro Ice Coffee -  nitro coffee in glass - Parker Industrial Gas Filtration and Generation Division"The Parker DN-6 provides nitrogen without any interruption. It’s always ready. Saved us at least four man-hours per week. It is awesome! We use nitrogen to push Kombucha too. Plug and play. It’s always working and saves us a lot of time. We also pour wine and we keep the wine bottle purged with nitrogen to keep it fresh. We are also looking at using it to pour our beer too.”

    — Sal DiFranco, Battlegrounds Coffee

     

    "We were always fighting with the tanks to work properly to pour the perfect pour for a nitro cold brew. Since we’ve had the nitrogen generator it has been easy breezy. With a generator, you don’t have to worry about it. You set and forget. We never have to tell customers 'Sorry we aren’t pouring today.' The pour looks great, tastes even better.”

    — Dana, Battlegrounds Coffee

  • Making Good Sense of Sensor Installation - Citrus - Pneumatic DivisionCareful and correct sensor installation is vital if accurate and reliable information is to be measured and communicated from the sensor. 

    What all engineers want when it comes to sensor installation is a simple, secure and rapid assembly process, without complicated processes such as the need for additional mountings. 

    The P8S proximity sensor offers universal use, flexible integration and excellent form. Its square design is also suitable for rapid installation in industry-standard T-slots, regardless of cylinder profile or brand. The upshot of this direct, drop-in design – as opposed to ‘turn-in’ or ‘slide-in’ concepts – is a significant reduction in installation time. 

    Making Good Sense of Sensor InstallationAmong the innovations with the P8S are retaining ribs on the side of the sensor body that enable simple mounting, including hard-to-reach locations or overhead assemblies. These ribs ensure the sensor conveniently holds its position in the T-slot even before the screw is tightened.

    To begin the installation, simply slide the sensor into the T-slot. When in the desired position, a quarter-turn of the eccentric stainless steel screw is all that is required to secure the sensor. To further simplify mounting, the screw head design is such that it accepts either a flat-blade screwdriver or Allen key. The mounting screw even features a knurled head that helps to withstand shock or vibration.

    Of course, not all cylinders have T-slots. With P8S sensors this is not a problem as they also mount externally to cylinders. As a result, fitment to round, tie rod and profile cylinders are straightforward.

    To make life as simple as possible, every P8S sensor is delivered with a specific adaptor to suit dovetail grooves. Also available are special brackets for round and tie-rod cylinders. The concept is to provide one sensor for all actuator types and brands - not just Parker units.

    Cables are be supplied in three or 10 metre lengths (flying lead) or 0.3 metres with an M8 rotating plug, as standard. 

    Ultimately, automation demands excellent functionality and precision, which in turn requires solid expertise and knowledge at all levels, including best-practice installation.

  • HVACR Tech Tip: Top 5 Most Frequently Asked Questions About Thermostatic Expansion Valves (TEVs) - HVACR Technician diagnosing air conditioning unitNot everyone is familiar with all the intricacies of HVACR as we are at Parker Sporlan and that’s okay. Whenever you have questions, you can always contact our world class Technical Support team or check Parker.com/Sporlan for in-depth information and guidance. Our Climate Control Blog has many of the answers you need for questions on most topics, so dig in. Below, we’ve answered some of the most frequently asked Thermostatic Expansion Valve (TEV) questions – you’ll find easy answers to your need-to-know questions.

      Where should the TEV external equalizer be installed?

    The purpose of the external equalizer is to sense the pressure in the suction line AT THE BULB LOCATION and transmit it to the TEV diaphragm. This usually means installing the external equalizer immediately down stream from the bulb. This ensures the correct pressure is signaled to the TEV. In some situations, this “ideal” location may not be possible. In these cases, an alternate location could be used. However, the pressure at these locations must be nearly identical to the pressure in the line where the bulb is located. In other words, alternative locations are acceptable as long as these pressures are essentially the same as when the system is operating at full load. In the past there has been concern about installing the external equalizer “up-stream” from the bulb. This was due to the possibility of refrigerant leaking past the TEV push rods, passing through the equalizer line and into the suction line, thus falsely influencing the TEV bulb temperature. Today, with Parker Sporlan’s TEV design, this possibility is virtually eliminated.

      Where should the TEV’s bulb be located?

    In general, the TEV bulb should be installed on a straight section of horizontal suction line. When the compressor is above the evaporator – Locate the bulb on a straight, horizontal line, pitched slightly down, immediately after it leaves the evaporator. A short trap should follow before the vertical line rises to be connected to the compressor suction. With the line pitched down, any liquid refrigerant and/or oil will pass into the trap, away from the bulb. As the trap fills with oil, the velocity of the refrigerant will carry the trapped oil into the vertical section and be returned to the compressor. When the compressor is below the evaporator  No trap is required after the bulb location, but the line should be pitched slightly down to prevent any liquid refrigerant or oil from being trapped at the bulb location. When several evaporators are installed both below and above the common suction line – Observing the same principles outlined above, the piping should be arranged to prevent the accumulation of oil and/or refrigerant at the bulb location. Also, traps installed in the suction lines of evaporators prevent the refrigerant from one evaporator from entering the suction line of another evaporator.

      Should a Parker Sporlan Thermostatic Expansion Valve (TEV) be adjusted after installation?

    HVACR Tech Tip: Top 5 Most Frequently Asked Questions About Thermostatic Expansion Valves (TEVs) - Thermostatic Expansion ValveBefore leaving the factory, a specific superheat setting is made on each and every Parker Sporlan TEV. A standard superheat setting has been established for every size and every thermostatic charge. This standard-setting provides the proper superheat on the average system to which the particular TEV size and charge is likely to be applied. Therefore, in most cases, a superheat adjustment on the job will not be necessary. Parker Sporlan recommends a change in the superheat adjustment only after it has been determined that it is required. Careful measurement of the operating superheat, using the recommended procedure, will establish if a change would be beneficial. To reduce the superheat, turn the adjusting stem COUNTERCLOCKWISE. To increase the superheat, turn the adjusting stem CLOCKWISE. When adjusting the valve, make no more than one turn of the stem at a time and observe the change in superheat closely to prevent over-shooting the desired setting. On adjustable TEVs, Parker Sporlan attempts to position the adjusting stem at the half-way point when it is at the standard-setting. This allows maximum adjustment in both directions. Parker Sporlan supplies a number of OEMs with non-adjustable TEVs. The OEM determines the superheat setting through laboratory testing of the unit. Some of these valves can be converted in the field to adjustable models.

      How can I tell if my TEV is adjustable?

    Most of the TEVs listed in Parker Sporlan Catalog 201 or Bulletin 10-10 will be adjustable unless there is an “N” stamped in the valve body as part of the nomenclature (i.e. NSVE-5). Many of the valves made specifically for OEM customers are non-adjustable. One way to tell if a valve is adjustable or non-adjustable is to look at the bottom cap. Adjustable expansion valves will have a threaded joint between the valve body and bottom cap as well as a threaded joint between the bottom cap and a hex seal cap that is removable to expose the adjusting stem. Non-adjustable valves, on the other hand, will generally have only one threaded joint between the valve body and bottom cap. An exception to this rule is a factory adjustable valve with two threaded joints and a smooth, round non-removable seal cap. Many non-adjustable valves can be converted to adjustable by changing the bottom cap assembly. Contact Parker Sporlan’s Technical Support department for more information. They will need all the information you can get from the valve’s markings to assist you. CAUTION: Never attempt to determine if a valve is adjustable by removing the bottom cap assembly unless the system has been pumped down, it could result in serious injury.

      Can I replace the powerhead on my Parker Sporlan TEV and how do I know what to get?

    With a few exceptions, most Parker Sporlan thermostatic expansion valves manufactured after 1993 have replaceable thermostatic elements. The exceptions are valves with an “H” before the valve nomenclature (i.e. HSVE-10), the now obsolete Platform valves, and the relatively new HX valve. The Platform and HX valves can be identified by a stainless steel element. The valves with the “H” in the nomenclature have had the elements soldered to the valve body at the customer’s request. Parker Sporlan makes replacement element kits that are available through Authorized Sporlan Wholesalers. The thermostatic elements on Parker Sporlan expansion valves are identified by a series of numbers and letters. The number (i.e. 33, 43, 83, etc.) identifies the element size, while the letters (i.e. VGA, RC, JCP, etc.) identify the refrigerant and thermostatic charge. A replacement element kit can be obtained based on that information. For example, a valve with markings on the element of 83 and VCP100 will require a KT-83-VCP100 element kit. (For more information on element identification, consult Bulletin 210-60.) If markings on the element are no longer legible, contact Parker Sporlan’s Technical Support team for help in selecting a replacement element. They will need all the information available from the valve body, and a description of the application. To completely identify a Parker Sporlan thermostatic element the following information is required:

    • Element size number

    • Refrigerant Thermostatic charge

    • MOP (Maximum Operating Pressure) if other than standard E

    • Capillary tubing length

    • Bulb size if other than standard
