It seems like September is a little early to be thinking about colder weather especially here in the South, but that’s exactly what we should be doing. Now is a great time to be proactive and get your compressed air system prepared for what is coming. My favorite definition of “Proactive” is acting before a situation becomes a source of confrontation or crisis. When cold weather hits, compressed air systems can struggle, and a variety of problems can arise. Slow starting, line freeze problems, sensor malfunctions and equipment failure are all things our service department sees every winter. By taking a proactive approach and preparing your equipment for freezing temperatures you’ll be protecting yourself and your compressed air system from having to deal with a cold weather “crisis”. Of course, you could just sit back, wait and take the reactive approach which usually consists of emergency service calls, air freighting parts and sometimes a rental compressor…
Here is a basic cold weather checklist:
- If your equipment is outside, make sure you can protect it from the wind and use floodlights or heat lamps to keep your controls from freezing.
- Check insulated areas and make sure the heat is staying inside and the cold is staying outside.
- Also, check any weather stripping and replace areas that are worn out and not working properly.
- Check condensate drains throughout your system for proper operation. Excess water in your lines and freezing temperatures are not a good mix. Install heat tape on anything that is exposed.
- Check the intake for your air compressor. If it’s exposed to the outside elements, your inlet air filter can be damaged from ice and snow.
- Compressed air receivers should be protected as well. If condensate collects at the bottom of the tank it can freeze. Insulate any outside pipes feeding the tank as well as the condensate drain for the tank and make sure the drain is working properly.
- Kind of a no-brainer here, but make sure your compressed air dryer and compressed air filters have been serviced and are operating correctly. Their job is to remove the condensate from your compressed air system. The less condensate in the system the less there is to freeze and cause problems.
Contact us today if you need any help with addressing your cold weather vulnerabilities. Taking these proactive steps now, can help prevent some major problems once it turns cold outside.

We recently did a blog post on Summer Preventative Maintenance, (check it out here). One of the key points listed in that post was making sure your oil/water separators are operating properly. So let’s take a look at what an oil/water separator is and why it is so important.
A typical compressed air and gas system can produce a tremendous amount of condensate each year so it’s important to know how to treat oil or water condensate in a compressed air system. This condensate is usually a mixture of condensed water and hydrocarbon vapors. It’s extracted from your compressed air system at various points. The compressor aftercooler, compressed air receiver, compressed air dryer and various line filters. So what do you do with all of this “stuff”? You need to either collect it and pay someone to haul it off or you can treat it and dispose of it properly. Since over 98% of the condensate is pure water it makes sense financially to separate the lubricant from the condensate then dispose of it properly. An Oil/Water Separator will do that for you.
Traditional oil/water separators operate on the basis of using a settling tank and gravity to do the bulk of the separation. Oil is skimmed off the surface and discharged into a separate container for proper disposal and the rest of the condensate, up to 98% of it is sent through a filtration process, usually a bed of carbon. The carbon bag/filter has to be maintained on a regular basis to ensure your discharge water is meeting government regulations in your area. The “settling” tank has to be emptied and cleaned and the carbon bags have to be pre-soaked with water before you install them. Proper sizing is key here due to the variety of synthetic lubricants on the market and fluctuating humidity levels. If a system is not sized correctly, media life is shortened and system back up can occur, spilling oil and making a general mess.
Newer designs of oil-water separators have been coming out recently to make the separation process more environmentally friendly and easier to maintain. Our friends at nano Purification Solutions have a great product that addresses the pain points of a traditional setup. Their design utilizes a unique filtration media that not only outperforms carbon technologies but is also made out of environmentally recycled materials. It’s so efficient that there is no need for oil skimming and collecting. The media is very light and there is no pre-soaking before installing it. You have one discharge port with clean water, down to 5 ppmw or less.
Important Points to Remember:
- Proper disposal of oil/water condensate is required by law
- Separating and treating it on site results in considerable savings
- Employing the latest technology from nano and Lewis Systems gives you peace of mind. (you don’t want the EPA knocking on your door).
During the summer, there are a few extra challenges your compressed air system faces. Heat and humidity can cause all sorts of problems if you don’t prepare your system to adequately address them. Here are a few simple compressed air summer maintenance tips to keep your system running efficiently.
Checking Your Compressed Air System
- Heat Exchangers – Check your after coolers and oil coolers to make sure they are clean and fans are operating correctly. These coolers are your primary defense for keeping your oil temperatures acceptable and removing the bulk of your liquid water from your compressed air system.
- Condensate Drains – With the extra humidity there will be extra water. Check all of your drains and drain lines to ensure they are sized correctly and operating properly. If you are using timer operated drains, you will need to adjust your frequency to allow for the increase in condensate.
- Air Dryers – Both refrigerated and desiccant compressed air dryers need to be checked and prepared for the summer heat and humidity. Condenser coils and condenser fans should be checked on refrigerated dryers. Pre-filters and drains should be checked and serviced on desiccant dryers to protect the desiccant bed from slugs of liquid water and oil.
- Oil/Water Separators – All the water that your drains and dryers are removing should be routed to an Oil/Water Separator. These separators help you safely and legally dispose of your compressed air condensate. Be sure to replace all carbon bags and filters every six months to ensure proper operation.
Lewis Systems & Service Co., Inc. carries a full line of drains, dryers and filters to help your compressed air systems to deal with the heat and humidity that the summer brings. So give us a call if you find yourself “under water” this summer.
