The Benefits of Intelligent PCLS and Pressure Compensated System Architecture Planter Global Mobile SystemsToday, planters typically drive tractor pressure to high-pressure standby, generating excess heat and reducing fuel efficiency when tractor remotes are used to power fans, compressors and fertilizer pumps. Hydraulic downforce systems can also require high pressure at low flow driving the tractor to maximum pressure. 

Multiple planter systems are typically controlled using the main tractor directional valve. The tractor pump usually operates at max pressure during planting creating: 

  • Excess heat 
  • Reducing fuel efficiency 

The Benefits of Intelligent PCLS and Pressure Compensated System Architecture

The Parker application solution Dedicated low volume piston pump for hydraulic downforce  

By using a dedicated pressure-compensated pump driven by the tractor’s PTO to power the planter hydraulic downforce system, the tendency for the tractor pump to operate at high-pressure standby is reduced, thereby reducing a major contributor to excess heating and poor fuel consumption. Pump should be low displacement, sized to handle downforce flow needs. Pump also provides supply pressure to operate the Power Beyond pump. 

The pump has a secondary function by providing a pressure source for a proportional pressure control valve which can be intelligently controlled via the tractor power beyond load dense port. 

     Intelligently controlled tractor pump through power beyond 

By intelligently controlling a tractor pump by using the tractors power beyond option, the planter has complete control of the pump providing freedom to design and control the planter as desired. Pressure sensors at the fan and fertilizers functions allow for intelligent electric load sense, removing the need for additional hoses.

    Potential Energy Savings

By separating the hydraulic downforce from the other planter functions, the tractor and planter power usage is optimized, reducing heat and therefore improving overall efficiency and component life. By controlling the tractor pump directly the planter is free to control the fan, fertilizer, and other accessory functions more intelligently.

Process Cooling Accelerates Throughput in Food and Beverage Manufacturing - Process Cooling Application - Parker GSFEThe food and beverage industry is the largest manufacturing sector to use chilled water systems. Applications within the industry are very diverse due to the wide range of product types and how they are produced. Applied to most food applications through to packaging, cooling is a way of speeding up the throughput of produce, as it reduces the time after cooking or baking.

The soft drinks industry requires cooling during the process of fizzy drink manufacturing. The fizz is provided by carbon dioxide, which is injected prior to packaging into bottles or cans. If the product is not chilled, the carbon dioxide will boil off, and frothing occurs; chilling the product is key to maintaining product integrity.

Precision cooling is a key factor in meeting some industry standards and ensuring consistently safe production methods are used. In addition to the regulatory requirements, precision cooling is also used to speed up the process, so that manufacturers can reduce lead-times and save money.

Process Cooling Accelerates Throughput in Food and Beverage Manufacturing - view the interactive - Parker GSFEFor more information on the benefits of precision cooling in food and beverage applications, as well as chiller system operation and design guidelines, view the interactive.


Cooling in the food production process

Chillers are prevalent in most types of food production. Broadly speaking, if a food is heated for cooking or baking, then it is likely to require cooling down prior to finishing and packaging. In some instances, it is necessary to cool specific ingredients during the process. In a bakery, the dough is typically mixed with cooled water, as this controls the yeast rising and allows consistency.

Some key methods of cooling product applied during production are:

  • Jacketed vessels
  • Scraped surface heat exchangers
  • Cooling tunnels
  • Gasketed plate heat exchangers


Some typical illustrations below:

Specific machine cooling for packaging machines

At the end of production, almost all food and drink needs to be packaged. Most companies install machines specifically designed to pack the produce using an automated system. Some of these machines are manufactured by global OEM companies and others are bespoke systems, designed and installed by specialists in the field.

Irrespective of their origins, most of these machines adopt the same principle whereby they hermetically seal the food within a container to preserve shelf life.

The sealing process uses a heated tool to apply the seal and chilled water to set and free the package from the tool. These machines can sometimes be supplied from a central cooling system, or more commonly, will have a dedicated process chiller located at the point of use.

Centralised cooling systems vs. dedicated process chillers for multiple factory applications

Process Cooling Accelerates Throughput in Food and Beverage Manufacturing - Process Cooling Chiller - Parker GSFECentralised cooling systems have some benefits but also limitations. If well designed, they can be more efficient than small, single, point of use chillers, and combining multiple chillers in a modular system provides a robust solution. Hyperchill units are designed to be installed into a combined modular system, with the ability to add further chillers to increase capacity to customers’ needs.

Individual point-of-use chillers are generally used where numerous applications within a food or drinks factory have different operating criteria for water temperature and pressure. Parker Hyperchill and Hyperchill Plus units are designed to be fully configurable to meet the specification of these applications.

Potable water

Potable water is widely used both as a food ingredient and in food preparation. A town’s mains water supply is inconsistent, with temperature values increasing in summer and decreasing through winter.

The solution is to combine a chiller with an external heat exchanger and tank, packaged with a control system to deliver a metered volume of water at the specified water temperature.

The system package size is based on batch size, cycle time and water temperature. The chiller water circuit and process potable water circuit must be independent, as food standard regulations do not allow potable water to be directly cooled by a chiller, due to the risk of refrigerant contamination. Hyperchill and Hyperchill Plus are ideally suited to potable water packaged systems.

Meeting Marine and Offshore Approvals is Key to Delivering Safety at Sea Marine Mobile Systems Division EuropeThe safe navigation of ships in challenging marine environments is a testament to the skill of the crew and the performance of the equipment they use. In offshore applications, the ambient environment can become hugely unpredictable, with wildly fluctuating temperature, humidity and vibration. This puts instrumentation and automation equipment under extreme duress, at a time when the performance of such systems is most critical to operators. 

Fortunately, mandatory marine type approval exists to ensure that safety-critical apparatus installed on any classified vessel is fit for the task at hand. The stringent UR-E10 test specification from the International Association of Classification Societies, for example, provides strict criteria for the test requirements for electrical, electronic and programmable equipment intended for control, monitoring, alarm and protection systems for use in ships and other offshore applications.  

At its heart, UR-E10 demonstrates the ability of equipment to function as intended under specified testing conditions - which is a comforting thought in marine and other offshore environments, no doubt, as the waves swell and the weather closes in. 


Designing for stringent standards 

For equipment suppliers, meeting the requirements of UR-E10 is a result of considered design at every stage of the product development process, with engineers working hard to ensure that equipment meets strict electrical, Electromagnetic Interference (EMI) and environmental performance expectations. For UR-E10, specifically, there are a whole host of multi-point tests covering varied aspects of performance including an external power supply failure test, Electrostatic Discharge (ESD) and surge immunity, dry and damp heat, vibration and flame retardancy, to name but a few. 

Achieving marine certification is, therefore, no mean feat. That’s why here at Parker, we are pleased to announce that the Pro Display 10 human-machine interface has now achieved UR-E10 and also fulfills Electromagnetic Comapatility (EMC) requirements for installations in general power distribution zones providing customers with a space-saving, cost-effective and reliable Human Machine Interface (HMI) solution for marine and other offshore applications.  

As well as guaranteeing performance in the harshest conditions, the Pro Display 10 comes with a full set of functions to support marine crews. The rugged 10-inch display module features multi-touch capability for ease of operation, even in the roughest of seas. The touchscreen interface enables rapid and accurate interaction with the display’s apps, although the platform can also be controlled using remote buttons or a pulse wheel if preferred.  

Furthermore, the use of in-plane switching (IPS) screen technology results in crystal clear images with impressive colour reproduction from wide viewing angles – a particularly important consideration in the highly variable light conditions that may be encountered in marine environments. 


Intuitive software delivers results 

Meeting Marine and Offshore Approvals is Key to Delivering Safety at Sea Pro Display Mobile Systems Division EuropeIn terms of software development, Pro Display is an app-based platform and provides tools for fast and advanced application development. Parker’s UX Toolkit enables better usability for customer HMI applications, by bringing modern features such as dynamic user interface, fluid UI animations, and easy-to-use and intelligent data management. With Pro Display, marine customers can deploy customized HMI functions such as machine functionality, diagnostics, data monitoring and visualization and work management. 

Moreover, Pro Display 10 can be a central HMI unit in a system or serve as a stand-alone display. A wide variety of communication interfaces supports versatile use within marine applications. For example, four CAN buses and Ethernet support communication for various systems in the application.  Besides the two analog camera interfaces, a number of IP-cameras can also be connected to via Ethernet switch or a WLAN access point. 


Meeting marine and offshore expectations 

The result, then, is a product that performs at the highest levels in the harshest conditions. And that’s what marine crews and offshore operators demand as they combine their skills and experience with cutting-edge technology to ensure safety at sea.
