Compact Flow Sensors from BEKO Technologies

Energy costs are high and set to go even higher. The beleaguered factory manager has to try to mitigate the impact of this together with all the other issues of the day that face him or her. Most companies addressed the problem that given 3 compressors 1 was just feeding the leaks in a campaign style activity...end of story...no sadly the leaks will come back or occur in other locations for a variety of reasons such as airline contamination, lack of maintenance just to mention a couple of the many.

BEKO TECHNOLOGIES decided the companies would increasingly want to measure key parameters in their compressed air or gas streams. The only way to manage is to measure is a mantra that is commonly used in businesses. Compressed air for many years was poor relations because almost everyone thought that compressed air was “free” or low cost so what was the point of investing in measuring something that didn’t impact on the efficiency and bottom line of a business. There have been solutions out there for many years to measure compressed air flow and indeed very reputable and impartial companies who would come along and measure flow using turbine flow meters and expensive technical personnel.

BEKO TECHNOLOGIES launched a range of measuring devices under the family name “METPOINT” and have been successful in selling surveys and the meters to measure, dewpoint, pressure, flow and even remaining oil vapour content. Today we are pleased to announce the availability of a compact flow sensor from BEKO. The advantages of such a device are that the price point means that more locations can be monitored. The device measures flow, total consumption and velocity. This means that exact costs can be attributed to individual pipe feeds into a process. It also helps with another aspect of energy saving in that pressure drop is a result of velocities being too high and now this can be monitored again in more locations.

The Best Just Got Better

UK Service Manager Chris Norris said “We have been very successful with the product claiming a significant market share for the free standing sales. We took advantage of the very low warranty defect rate and offered a simple “no quibble” warranty extension to 3 years and of course we hoped that the designers would not get over zealous about value engineering and replacing what I regard as key components in the product’s reliability with lower cost items which might affect the product’s integrity. We have all seen this happen!”

Norris goes on to describe the changes made, “The product only needed some tweaking and we were pleased to see that the controllers were brought up to a high standard, the smaller units having a relatively simple display but doing all the necessary tasks including controlling the BEKOMAT level sensing drain, also allowing the drain test to be carried out from the control panel. Obviously I am always pleased to see service indication on products particularly very reliable products which can get abused because of this virtue.

On the 3 phase line we have scroll compressors fitted from RA1080. This helps keep noise and vibration down and allows a simpler connection, all helping to keep costs down. We have some new features such as Advanced Service Warning, Advanced Fan Control which allows the fan to run at 50% speed saving energy and helping to keep a constant dewpoint. All alarms and operating data are stored in the system to help prevent failures and if they occur to quickly diagnose the cause of the problem. The refrigerant has also been changed to R407C which has a significantly lower GWP (Global Warming Potential) than R404a.

Chris Norris summarises by saying “We in the UK are very satisfied with the new range. We believe that we will get even stronger in the market by offering what customers want, reliability, performance to the specification, connectivity, and ease of maintenance via good information from the control system. We are confident that our DRYPOINT RA range will give customers the lowest cost of ownership and publish our pressure drop and total power input for customer scrutiny. It’s a pity not all do this. In fact some of our competitors publish neither and some just the power. It is really important to understand that the upfront cost of the product is only half the story!

A Paradigm can be Shifted

When a plant engineer has to purchase a compressed air dryer his first thought will be what dewpoint is required. This will then depend on the application; specifications of machinery using compressed air will guide the engineer as will codes of practice such as BRC/BCAS for the Food Industry. If a negative dewpoint is required then a desiccant dryer will be selected. The genre is likely to be well known to the engineer and will attract a significant capital and running cost particularly if a lower capital cost heatless dryer is selected. However the solution is classic and cannot be faulted. The alternative scenario is for the positive dewpoint at typically +2º C and again the engineer will know that a refrigeration type dryer will handle this application with relatively low capital and running cost but that he must take care not to have pipework going below the dewpoint temperature.

There is a third solution which is mostly ignored or perhaps is not fully understood. This is the membrane type dryer and BEKO TECHNOLOGIES offer their DRYPOINT M range of membrane dryers alongside their EVERDRY and DRYPOINT RA, desiccant and fridge dryers. Steve Riley, General Manager of BEKO TECHNOLOGIES in the UK and Ireland comments “I was amazed at how many DRYPOINT M’s were being sold when I joined the company. A little research told me
that 20,000 units had been sold since launch, in the UK alone. I could guess that many purchasers were “Original Equipment Manufacturers” because the main benefit I had in my mind was the very small footprint. I knew also that some compressor manufacturers had a packaged unit which included a membrane dryer but I couldn’t for the life of me guess the diversity of applications”.

He was correct in his thinking but later researches told him that there were very good reasons for engineers to select DRYPOINT M just on overall cost. This needs some explanation as what tends to put most engineers off is waste and it is a fact that membrane dryers lose a quantity of compressed air in purge loss. However this is not fixed and BEKO’s sales people have software which enables the choice of a low capital cost, higher purge loss unit or a higher capital cost and lower purge loss unit of energy cost is important (and when isn’t it). Riley comments again “I don’t think anyone will be too surprised to know that one of the other statistics I wanted to understand quickly was what maintenance revenue I would get from all these units. It was an unbelievable number- Nothing, £0 and it is not a short lived product that if a problem should occur it is more economical to throw it away. It is possible to destroy the membrane by having too much liquid ingress but BEKO’s experience and design team have produced a dryer with close coupled separator and drain to protect against this eventuality.” In fact there are no wearing or replaceable parts.

The Third Way - Update

BEKO TECHNOLOGIES launched the BEKOKAT Catalytic Converter in 2008 realising that there would not be a flood of sales but none the less expecting to see a slow take up of the product notably by companies who had a need for 100% oil free or better than ISO 8573 Class 1 quality. The reason for this expectation was the growing realisation that however good an oil free compressor can be, the quality of air entering the compressor is variable. BEKO using their METPOINT OCV device have measured Class 3 remaining oil content after an oil free compressor with the unit working perfectly and not adding any hydrocarbon to the system.

Three years down the line and over 100 units sold. BEKO are optimistic that the success of the existing units in the field together with the increasing requirement to audit the quality of compressed air will accelerate the growth in sales. Chris Norris Service Manager at BEKO UK comments “As a service person I shouldn’t be happy because I have had no service revenue from the installed base this year and only a little last year but it is really pleasing to know that on at least one case, serious contamination was prevented in a food factory when an oil separator dump occurred. We expect this product to be very low service costs on average. There will be the replacement of the catalyst every 20,000 hours but annually virtually nothing apart from checking safety systems and valve operation “.

The product sales are helped by the fact that BEKOKAT is certified to produce amicrobic compressed air by the German GFPS (which translates as the Society for Production Hygiene and Sterility). Two units have already been sold in the UK just for this reason and the units are working well. The other applications are in the food, beverage, nuclear and pharmaceutical industries. Norris says “The BEKOKAT is not meant as any kind of competition to the oil free compressor it will be installed where it is critical that the air shall always be of the highest quality regardless of the condition of the inlet air”.

90 Degrees Shaft Coupling in One Piece

Most flexible shaft couplings rely on a number of moving parts to enable the transmission of torque through a high angular offset.  The Helical Flexure is an advanced solution that can accommodate up to 90° of angular misalignment whilst simultaneously compensating for axial and parallel shaft misalignments, but delivering all of these advantages from a single piece construction.

The performance capability of each shaft coupling is determined by six major characteristics:  outside diameter, inside diameter, coil thickness, material, number of coils, and the number of starts. By altering these characteristics, torque capacity, angular and parallel misalignment capabilities, torsional and lateral bending rates of flexured u-joints can be modified to suit specific specifications and/or requirements.

The high angular shaft offset couplings are manufactured from stainless steel as standard so are ideal for medical, food processing or any clean room environment applications. The designer benefits from a number of advantages which include a choice of materials, the ability to have an infinite choice of end attachments and most importantly a maintenance free product.

Schmidt Thoroughbreds Join the Stable

It gives us a great deal of pleasure to announce that we are expanding our wide choice of shaft coupling products with a brand new offering – the SCHMIDT-KUPPLUNG® range of compact coupling systems.  This outstanding array of products provides an excellent choice, addressing different customer needs for a high performance standard item, a coupling adapted to their particular sector, or a solution tailored to a specific single application.

•    Controlflex® – the perfect coupling for shaft encoders, accommodating all types of misalignment with very low restoring forces and low stress on the encoder bearings at constant angular velocity.

•    Semiflex® – torsionally stiff, precise and backlash-free shaft couplings that require little axial space, compensate misalignment without restoring forces and transmit torque between shafts in instances where shaft alignment cannot be guaranteed.

•    Schmidt-Kupplung® – the classic product for extreme parallel offset, this torsionally stiff shaft coupling compensates variable parallel shaft offset without side loads in a very compact envelope.

•    Loewe® GK – with high axial stiffness and multiple shaft connections, this coupling is ideal for torque applications requiring resistance to axial motion, the mix of kinematic properties allowing much radial and angular misalignment.

•    Omniflex® – offering high universal shaft misalignment compensation with compact dimensions, this torsionally stiff and robust coupling is purpose designed for maximum torque requirements and the toughest cycle operations.
