CFM Air Equipment Canada helps plants across the Prairies keep moisture out of their lines with Hankison air dryers matched to real demand. Wet compressed air is one of the most common causes of tool failure and product defects. The good news is that the fix is well understood. This guide covers the moisture problems you face, the dryer types that solve them, and how to keep performance steady year round.
Why Moisture Is a Hidden Threat
Every compressor pulls humid air from the room. As that air is compressed and cooled, water drops out inside your pipes. This water then rides along to your tools and processes. The result is rust, frozen lines in winter, and ruined finishes.
Moisture damage builds quietly over months. You may not see it until a valve sticks or a paint job fails. By then the water has spread through the whole system. Drying the air at the source stops the problem before it starts.
The Prairie climate makes this worse. Humid summers load the air with water, while cold winters freeze any that remains. A good dryer handles both extremes with ease. That is why dryer choice matters so much here.
Temperature swings also change the amount of water the air holds. Warm air carries far more moisture than cold air. When that warm air cools in your pipes, the water drops out fast. A dryer removes that water before it ever reaches a tool. Sizing for the warmest, most humid day keeps you safe all year.
Signs Your Air Is Too Wet
A few clear symptoms tell you moisture is winning. Catching them early keeps repairs small. It also protects the quality of your finished work.
- Water spraying from tools or hose ends
- Condensation pooling at drops and drains
- Rust forming inside tanks and fittings
- Frozen air lines during cold snaps
- Blistered or fisheyed paint finishes
Each symptom points back to excess water in the air. The right dryer removes that water before it causes harm. For the parts that support clean, dry air, our filter and drain components keep the whole system working together.
How Hankison Air Dryers Keep Air Dry
Hankison air dryers come in two main families. Refrigerated units chill the air so water condenses and drains away. Desiccant units pass air over material that pulls moisture out. Both lower the dew point, just to different levels.
You can explore the full dryer selection to see which style fits your plant. The table below compares the common choices at a glance.
| Dryer type | How it works | Best fit |
|---|---|---|
| Refrigerated | Cools air to condense water | General shop and plant air |
| Cycling refrigerated | Cools only as needed | Variable or lighter loads |
| Desiccant | Adsorbs moisture onto media | Low dew point processes |
| Membrane | Separates water vapour | Point-of-use and remote drops |
Matching the dryer family to your dew point target is the key step. A general shop rarely needs the driest air available. A paint line or instrument supply often does. We help you draw that line clearly.
Choosing the Right Hankison Air Dryers for Your Plant
The best dryer depends on your dew point goal, flow, and climate. Prairie winters add a twist, since very cold outdoor runs demand extra-dry air. We walk through each factor so the choice fits your real conditions.
Start With Dew Point
Decide how dry the air must be for your most sensitive task. Set the dryer to that standard, then supply the whole plant from it. Industry guidance from the Compressed Air and Gas Institute helps frame realistic dew point targets.
Size for Peak Flow
A dryer must handle your busiest moments, not just the average. An undersized unit lets dew point climb when demand spikes. We size each dryer to peak flow so performance holds steady. Right-sizing also avoids wasted energy on quiet shifts.
Pairing Dryers With Filters and Drains
A dryer rarely works alone. Filters remove oil and dust, while drains remove the water a dryer drops out. Together they form a complete air treatment train. Skipping one stage weakens the whole chain.
Industry estimates link a large share of pneumatic faults to moisture. A balanced setup of dryer, filters, and drains keeps that risk low. We design the train so each part supports the others. The result is clean, dry air at every drop.
Placement matters as much as the parts themselves. A dryer works best after the air has cooled a little. Drains belong at every low point where water collects. We plan the layout so moisture has nowhere to hide.
Good drains are easy to overlook, yet they do heavy work. A failed drain sends water straight back into the line. Simple electronic or timed drains solve this reliably. We check them during every service visit. A blocked drain can undo the best dryer in minutes, so we never skip them.
Keeping Dryers Working All Year
A dryer needs light, regular care to stay on target. Drains must work, coils must stay clean, and desiccant must be fresh. Skipping this care lets dew point creep up slowly. That creep often goes unnoticed until water returns.
A seasonal service visit catches these issues early. We test drains, check dew point, and clean what needs it. Our dryer servicing team keeps your air dry through summer humidity and winter cold alike.
A short log makes this care easy to track. Note the dew point and drain checks at each visit. Over time the log shows trends before they become faults. That record turns guesswork into a clear plan. It also helps the next technician pick up right where the last one left off.
Frequently Asked Questions
What do Hankison air dryers actually do?
Hankison air dryers remove moisture from compressed air. Dry air protects tools, valves, and finished products from rust and defects. Refrigerated models cool the air to drop out water. Desiccant models adsorb moisture for very dry air.
Refrigerated or desiccant: which should I pick?
Refrigerated dryers suit most general shop air. Desiccant dryers fit processes that need very low dew points. Your climate and application drive the choice. We help you weigh dew point, flow, and run time.
How do I know my dryer is undersized?
Water at the tools is the clearest sign. Rising dew point and condensation in lines also point to a sizing gap. Hot summer days often expose the problem first. We can measure dew point and confirm the right size.
How often do air dryers need service?
Most refrigerated dryers need a seasonal check and drain test. Desiccant dryers need periodic desiccant and filter attention. A short service visit keeps dew point on target. We set a plan around your run hours.
