Compressed Air Heat Exchangers

Great article by Wolfgang Kräusslich, Senior Chief Editor of Fluid magazine on customized heat exchangers saving space and money for Kaeser Compressors

Particularly when it comes to cleaning the water side, shell and tube heat exchangers have advantages over plate heat exchangers. Universal Hydraulik has now presented two innovations for this tried-and-tested product. One of these was given a closer look by fluid at Kaeser Kompressoren in Coburg.

RJW 8541 – Fail Safe Cooler

Sometimes, heat can be troublesome. It is generally created unintentionally, and if it is not wanted for the process, it must be dissipated. Cooling ­fins, fans and in certain cases appropriate heat exchangers are the tools of choice here. ‑ is also applies for compressors, where heat must be conducted away from both the drive train and from the compression process. Coburg-based compressed air specialist Kaeser Kompressoren uses air cooling alone for its screw compressors up to 30 kW, while for larger capacities air or water may be used, depending on the application and space requirements. The less space is available, the more water tends to be used. For units with three-­figure kW ratings, water cooling is the option most frequently used.

The Problem with Water Quality

Water – well, that sounds simple enough at first. But the devil is in the detail. Not all water is the same. And unlike in the oil or air side of a heat exchanger, the designer normally has less control over the quality of the water used. Each user deals with this issue differently; some put additives into the cooling circuit, while others have open circuits and highly varying qualities of water. Sometimes river water is used. But rivers can often be cloudy, and industry experts know that water ­filters are one of the components people economize on. Even where the water quality is tested in advance, a flood can turn a clear-running stream into a torrent of turbulent mud.

Additionally, substances such as chlorides or manganese in the water are invisible at first but can corrode away even the best stainless steel. It’s a similar story where seawater is used.

Both Tubes and Plates – Now Riding Piggyback

With their fi­nned design, plate heat exchangers contain a number of sharp internal angles, which makes them prone to contamination and becoming blocked. As a rule they are not easy to clean, unless one opts for large and costly models that can be unscrewed. Shell and tube heat exchangers, on the other hand, have smooth tubes on the water side that are less likely to attract dirt. If necessary the diameter of the tubes can be increased or the material adapted to the water quality. Various solutions exist, such as copper-nickel alloys (CuNi10 Fe), stainless steel (1.4571) or titanium, to cover most applications. The biggest advantage, however, is that this type of heat exchanger is very simple to clean. Just unscrew it, scrub it out and put it back together, you could say.

On the other hand, however, simple shell and tube heat exchangers have the disadvantage of requiring more space for a given cooling capacity. This is where Universal Hydraulik brings the hybrid heat exchanger into the game, combining the benefi­ts of both plate and shell and tube heat exchangers. This design has a greatly enlarged heat exchanging surface on the oil or air side, achieved through the use of plates drawn over the water tubes and linked to them by metal. This allows a unit to be created that is as compact as a plate heat exchanger. With this hybrid cooler, the manufacturer is now particularly represented in many Kaeser compressors used in advanced customer applications in difficult conditions such as marine environments. Another important factor; however, is that the loss of pressure caused by the heat exchanger inserted into the circuit must be as low as possible. Particularly in the case of air cooling and typically not more than 0.1 bar, and for this reason Kaeser has often ­fitted two heat exchangers. This is because where pressure loss is low, the level of compression can also be lower and thus a smaller motor can be used. For situations where space is very limited and only one unit can be ­fitted, meanwhile, the technicians of Universal Hydraulik have devised a market innovation – effectively two heat exchangers in one, in which the main tube carries another ‘piggyback’, as it were. The result: the required cooling capacity and a low loss of pressure, available for use where space is reduced.

Safety Heat Exchangers in Compact Format

In some situations, such as where river water or groundwater in an open-loop circuit is used for cooling, it is essential that no fluid from the oil circuit comes into contact with the water and that no water comes into the oil circuit. For such purposes, safety heat exchangers, which are also referred to as failsafe heat exchangers, are used – that is essentially a specially-designed double-tube heat exchanger. These exchangers also feature electronic monitoring for leakage that might occur, say, due to pitting corrosion.

Here again, Universal Hydraulik has come up with an innovation. Until now, safety heat exchangers have not been available in hybrid designs, and as a result they have been about three times larger for the same cooling capacity. With a new manufacturing process, however, it has become possible to make the gap between the tubes so small that the manufacturer can now house the double tube plus electronic monitoring in a hybrid model. This means that an ordinary hybrid cooler can now be replaced by a safety heat exchanger of the same physical size. And while Kaeser is not yet ­fitting the new safety heat exchangers into its compressors, it is good to know that it is available.

That’s a Wrap on IFPE 2014

IFPEThe 2014 International Fluid Power Expo was a huge success! Many of our existing customers stopped by our booth to say hello and we had the chance to meet new friends as well. 

On Wednesday, we are honored to be awarded Hydraulics and Pneumatics Magazine’s inaugural Best Supplier Industry Blog at the show as well. It was a wonderful surprise and we are grateful to the readers of H&P Magazine for bestowing this honor upon us.

This was the largest trade show booth we’ve ever had in our 25-year history. With many companies paring back on tradeshows, we ramped up our presence with a 20’ x 40’ booth (we’ve posted a few of the photos of our booth below. Let us know what you think.).

We were also thankful that six of our European suppliers were also able to join us at IFPE and provide expert insight into their products. A big thank you goes out to the representatives from BKM Serv-Clip, Jahn’s, Maier, Eckart, Universal Hydraulik and Spradow for making the trip.

We were sad to see IFPE 2014 end. We’ve already started to follow up. If we promised to send you additional information or pricing, it will be delivered shortly.

See you at IFPE 2017! 

Universal Hydraulik Driving Development of Customized Solutions

Universal HydraulikIC-Fluid Power manufacturing partner, Universal Hydraulic, was spotlighted in an article titled Spotlight on Test Stand Design in a recent edition of Fluid Magazine

Below is an excerpt from the article and a link to open the entire piece.

The family-owned Universal Hydraulik is undoubtedly a well-known company. Since time immemorial, the company has been associated with heat exchangers. However, very little has thus far been known about the expertise of the Hessen-based company in building test stands. All this is about to change.

The company that undertakes the development and production of heat exchangers, cooling filter systems, test stands, and much more besides, is not called Universal Hydraulik for nothing and has its head office in Neu-Anspach. However, it is important to remember that the Hessen-based company has been building test stands for the entire industry for a good 25 years. The management in Altlussheim and Lothar Nagel therefore had a very good idea of what they were letting themselves in for when the job was placed.

It all started at Internormen Technology because they were finding it difficult to cope with testing filters in the way they had been due to an ever growing product range and increased production volumes. Lothar Nagel remembers: “We had reached the limit of our capacity and therefore decided to go for a new test stand for hydraulic and lubricating oil filter, which we commissioned in 2005. We thus test all filter housings for tightness before we deliver them to the customers.”
