Mikropor is aware of the importance of high quality compressed air and guarantees to provide customers with the highest quality of air. Using clean, dry air is extremely important for all kinds of air powered applications. Moisture or contamination in the air which will come from the standard compressor outlet will cause complicated system errors.
These complications will decrease productivity and may affect the production quality of final products.

This is not only a dryer, but an air treatment package that delivers an air quality of class 1.4.1 as per ISO 8573:2010 due to integrated filtration
Applications
Mikropor provides an entire range of products for filtration and air purification applications at a cost effective price.
Applications Include
Food production, dairies, breweries, clean conveying air, chemical plants, pure air and cleanroom technology, pharmaceutical industry, weaving machines, photo labs, paint spraying, powder coating, packaging, control and instrument air, sand and/or shot blasting, general air works, microchip production, optics, process air as well as many other markets.
The MKE Series Refrigerant Circuit and Insulation
Mikropor only uses environmentally friendly R134a refrigerant gas in the dryers. This refrigerant is suitable for both low and high temperature applications. R-134a has excellent thermodynamic properties and can operate at very low pressure compared to other refrigerants. This will in turn increase the refrigerant compressor’s service life. With R-134a Mikropor dryers can operate at very high ambient temperatures. Mikropor engineers add extra power to the heat exchangers with excellent and extraordinary no loss insulation system. Mikropor dryers supply constant dew point at all flow ranges. This perfect insulation idea continues on the refrigeration circuit side as well. With this insulation concept and oversized condensers (Even for ultra-high ambient temperatures) Mikropor Refrigerated Air Dryers offer the highest technology with its custom solutions.
Digital Controllers
Digi-Pro digital controller is standard on MKE23-MKE3915 ESD digital controller is standard on MKE5085-MKE12500
Digi-Pro Digital Controller
Mikropor now produces a new generation of air dryers with Digi-Pro series controllers. With the Digi-Pro series controllers, air dryers have outstanding technology for both functionality and dynamism, as well as appearance. New controller design offers users the possibility of making adjustments with one finger, thus easier accessibility. The touch keys have taken the design and dynamism to a top level of technology. The multi-functional display provides an accurate digital dew point display as well as coded alarm monitoring of the refrigerant dryer.
Digital controller with embedded features,
Digital dew point monitoring
Energy-saving mode display
Periodic maintenance interval display
Status report
Hours run meter
Fahrenheit and Centigrade selection
ESD Digital Controller
Mikropor Refrigerated Air dryers with ESD Digital controller have a lot of economy features and alarm capabilities. Refrigeration dryers are usually the most efficient dryer solution for the compressed air applications. With the help of the highly engineered ESD, Mikropor Refrigerated Air Dryers will reduce your energy consumption. ESD helps the service technicians to monitor many useful parameters on the dryer and guides them to troubleshoot any problem very easily. ESD is extremely useful when there is no air coming into the dryer when the dryer is running. Especially during the nights, weekends and holidays many companies do not stop their dryers although they do not run compressed air. ESD saves huge amount of money by simply shutting the dryer down automatically when it is not in use.
Electrical Wires are Separated From Refrigerant Side
There are very few electrical wires inside the refrigerant side of the dryer. Electrical box has an external cover with access from the outside of the dryer. Therefore there is no need to open dryer panels electrical access.
Compact Design
Mikropor dryers are highly reliable, efficient and have small space demands and offer low cost ownership. Mikropor Refrigerated Air Dryers are suitable for the smallest installation spaces. Having two filters integrated into the dryer frame offers a huge advantage to the service technicians and end users. The integrated filters save labor time, piping cost and space at the facilities where the Mikropor Dryer is used. The compact size also offers flexibility and economy during their transport.
Aluminium Plate Heat Exchanger is Standard
Very low pressure drop
Thin aluminium plate thickness
High heat transfer surface area
Strong due to external thick cylindrical wall
Water separator is optimized for best performance
Scroll Compressors
Scroll Compressors are energy efficient and strong against liquid shocks. For energy saving, scroll compressors are used for 400 m³/h and above MKE Dryers.
Easy Access
Easy access to the cooling components in seconds by the help of screw free panels and plastic handless. Easy for service and offers more working space. Service technicians save time by not having to remove fasteners.
Zero Clearance Compressed Air Filters with High Performance Elements
Compressed Air Filter kit is standard on the Mikropor Dryers. The filter with X Element (coalescing filter for water removal) is used for up to 1 micron particles and the Filter with Y Element (coalescing filter for oil removal) is used to remove oil down to 0.01 ppm. Zero clearance design helps service technicians to replace the element in minutes. Mikropor Refrigerated Air Dryers are designed by engineers who have received all of the design feedback from field engineers and service technicians. This service friendly design makes Mikropor dryers very unique in the industry. Dryer Filter kit which has two elements, two automatic drains and two viton o-rings helps the customers to operate the dryer at its best performance until the next planned maintenance. Replacing drains on the filters is critical when replacing elements because drains will get clogged with dirt and oil over time.
Grooved Couplings and Fittings
On compressed air lines, grooved couplings and fittings are commonly used in the industry. These couplings increase flexibility on connections, help the service technician to dismantle and assemble pipes easily and quickly.
Excessive Water Droplet Drains
Liquid water droplets coming from the line to the inlet of the dryer are separated by the inlet filter and drained. Filter auto drains have manual valves on them. This allows the system to be depressurized when these filters go to service.
Replacement Filter Element
Pressure drop is a huge concern in compressed air. In many applications high pressure drops will cause a decrease in the pressure at the point of use. Sometimes this low pressure is not enough for the machines or processes to perform correctly. In addition, dirt particles and oil in the compressed air system may block the filters quickly. It is important for the end users and service technicians to recognize if there is a problem in the system. The performance of the filters directly affects the pressure drop and system performance. Therefore, it is very important that the filter elements are changed at the filter service time. An alarm/warning indicating that the filters are changed periodically is provided by a digital controller on the Mikropor Air Dryer. When this alarm triggers, the filter must be changed to avoid loss of performance and pressure drop.

Example for Choosing the Correct Dryer;
If a compressor delivers 200 m³/h at 6 bar the dryer inlet temperature is 40°C and ambient temperature is 30°C Please choose your Dryer as follows;
200 / 0.94 / 0.92 / 0.98 = 236 m³/h
The correct dryer for this application is MKE305.
Air dryers remove the moisture following the compressed air process. Dry compressed air is a concept with a wide range of meanings and dew point is an indication of how dry the compressed air is or needs to be. While air can be compressed, water cannot be compressed.
Why install a dryer for my compressor?
What would happen if water or moisture entered your machine? Water in wood causes rotting, water in metal causes rust, water in walls create mould. All of these are negative to the bottom line and a headache to any manager. Now in terms of an air compressor, moisture in your machine can damage the compressor, air motors, and valves, as well as possibly contaminate the product. All because a simple air dryer wasn’t installed. The cost of a new air dryer is cheap compared to loss of production.
Why is it important to know the size of my dryer needs?
When sizing an air dryer that keeps up with your application needs; it is important to get the right fit. A dryer that is too large will cause harmful wear and tear long before normal, opposed to having an undersized dryer can lead to poor air quality downstream.
Questions to keep in mind when you are sizing the dryer for your needs:
What is the desired dew point (how dry compressed air needs to be – this will determine whether it is a refrigerated or desiccant style dryer)?
• How much CFM will your compressor be sending through the dryer, and at what pressure?
• What are the ambient conditions of the dryer (ambient temperature, elevation, etc.)?
• What is the inlet temperature of the air going into the dryer?
Answering these few questions will give you a good start on selecting the right dryer technology and the appropriate size for your compressor. Remember, a desiccant dryer consumes 2% -20% of your CFM as purge air during the regeneration cycle of the vessels. With that in mind, you will need to make sure you make the necessary arrangements. If it is a new install, the compressor will need to be sized appropriately to compensate for the CFM loss during the purge cycle. If it is an existing install, you may have to upgrade the compressor. Ambient conditions and correction factors also come into play.

Hi Sam, Thank you for taking time to review our company. I'm so glad we were able to help! Kind regards Team CAS
I can't recommend CAS UK enough. We had a Clarke for a couple of years that we abused running it 12 hours a day. We found CAS UK when it needed a repair, and we were very impressed with how quickly they responded and came out to repair and service the machine.
Our business started to expand and we needed a large compressor with a proper airlines feeding our machines and work stations. The guys from CAS supplied the new compressor and worked flat out getting the machine and pipe working in. They're a brilliant group of lads with a great work ethic and really easy to communicate with.
We'll 100% continue to use and recommend them.

Took in what I believed to be a beyond repair compressor. Received back, an as new machine, all physical damage repaired and connector fittings renewed to latest standard. Compressor delivered to my premises in what was a great service by Compressed Air Systems UK. Thanks for a great experience
Me and my company have been using compressed air systems for around 10 years! Very professional always great advisor for the best machine for what we need, friendly office staff and most of all the knowledge from them is second to none. Would recommend to anyone that needs advise or want to buy the right machine for them. Plus the backup you get is the best.
What a refreshing team to have as competent suppliers for our leads and compressed air; not once have they given us poor service. They've saved our business; A Gilligan (Coatings) Ltd thousands of pounds per year with new high tech and efficient equipment. Their advice and service supplied over the last 15 year period has been extremely valuable, we would never consider another company for our compressed air services
Had a new compressor fitted a few months ago. Perfect service and amazing aftercare. I was advised well and even advised towards a better value option saving us a chunk of money. Top quality honest service all round...... Thanks again.
