Pfannenberg Water-Cooled Solutions for Greater Energy Efficiency


Heat is a single common by-product of today’s manufacturing machines that include the advanced automation technology required for both high speed operation and high precision. To keep these processes running, Industrial Cooling is critical.  When ambient conditions are at their worst liquid cooling is an ideal efficient solution.

The Challenge…

One of our machine tool customers needed a customized solution adapted to their customer’s environment allowing their industrial electronics to operate at optimal efficiency. Industrial cooling was needed for a grinding machine requiring cooling control accuracy. This is especially important as it significantly influences the grinding tolerance. The machine sands parts to remove all irregularities before sending them off for further assembly (gear manufacturing), the required control accuracy or hysteresis is up to +- 0.1 K in active units and up to +- 0.5 K in passive units.

The goal was to cool the machine with available water using a passive enclosure cooling unit at a flow temperature of 22°C. The main requirement for this project was that the water from the return flow (returning to the water ring) had to be at least 9°C warmer to match the customer’s own energy efficiency requirements.

The Solution…

After an analysis of their needs, Pfannenberg’s PWW Water to Water Heat Exchangers appeared to be the best solution. Our water-cooled solutions are designed with durable components to ensure the effectiveness and longevity of the critical cooling process at hand.

   


We installed our new passive PWW 6000 into our compatible EB 60 WT Chiller housing which is extremely flexible. Passive water cooling makes sense if the flow temperatures are not too low and if a water circuit is available. This solution works reliably at a temperature difference of more than 5°C between the water circuit and the chiller.

To support this new solution for our customer, Pfannenberg provided 2-days of on-site training bringing “live initial operations” online.

Thanks to the success of this installation, our customer secured 10 more projects using our PWW Water to Water Heat Exchangers with one in China.

Pfannenberg Cools Customers Worldwide


Pfannenberg’s North American headquarters are based in Lancaster, NY but the company serves customers around the globe with plants in Germany, Italy, China and recently Brazil.

Our internal company motto is “Sharing Competence” which allows worldwide teams to work together for a better understanding of our customers, providing dedicated service and solutions for projects globally.“This is the basis for our culture of innovation. We work closely with our internal teams, suppliers and customers to share information, developing an internal company know-how,” said Blaine Witt, Chief Sales Officer. “This process allows us to develop products and solutions based on what the market really demands.”

This strategy has not only contributed to receiving recognition as one of  “Western New York’s Fastest Growing Companies” for 2015 but also to global recognition as a recipient of a “Red Dot Award” award, won for our PYRA-MA Flashing Sounder.

Having manufacturing centers worldwide “allows our teams to work together to support the customer’s needs on every continent,” Witt said. “Looking forward, as technology evolves, our innovation will allow us to build new products that are intelligent and able to communicate with other systems.”

Our global presence and market know-how is a real competitive advantage as our Enclosure Thermal Management products help some of the largest companies worldwide stay cool and safe, protecting and keeping electronic equipment running to avoid costly downtime. We also manufacture visual and audible signaling devices for security, industrial fire alarms, building, industrial process, disaster warning, hazardous areas, light art and illumination.”

Pfannenberg’s Micro-channel AC cooling units for electronics cooling


Micro-Channel cooling is a proven cooling technology that has been used in the Automotive and HVAC industry for over 25 years. Pfannenberg was the first company to introduce micro-channel condenser technology to the industrial process and electrical enclosure cooling industry.

Our extensive 34X1 DTS range features our dual condenser fans with ultra efficient micro-channel condensers designed to meet all industrial environment expectations with products compatible with US regulations as Nema Type 12 indoor, Nema 3R/4 outdoor and Nema Type 4/4x stainless steel for washdown applications.

Pfannenberg’s DTS range of Cooling Units offer a smaller footprint, improved heat transfer efficiency while also providing an environmentally friendly solution by using 50% less refrigerant than standard coils!


Greater Efficiency

The micro-channel condenser coils utilize an ultra-efficient design providing up to 40% more heat rejection thanks to multiple channels
within the tube and a brazed joint between the tube and fin. This improves the transfer of heat from the refrigerant into the ambient air.

Single Row, Less Clogging & Fouling

The single row air flow path of the micro-channel condenser allows for a condenser air flow path that clogs less and is significantly easier to clean during general maintenance.

Corrosion Resistant & Less Weight

The 100% aluminum design with zinc coating increases the corrosion resistance – versus conventional copper tube and fin condensers – and significantly reduces the weight of the product.

Increased Durability

The Cooling Units design provides for a condenser coil that is harder to damage during transit and general handling of the cooling unit.  Fin combing is not required to maintain proper airflow channels.

Cost Effective Design

Machine production of the condenser and the reduced material cost of using aluminum vs copper tubing creates a significant savings over conventional copper tube and fin designs.

Uses 50% Less Refrigerant

In an age where many companies are required to account for and pay fees based on refrigerant usage, having a system that provides the same cooling capacity using 50% less refrigerant is a life saver for plant managers.
