CFM Air Equipment installs Hankison air dryers that give Calgary facilities clean, dry compressed air every shift. Wet air corrodes tools, freezes lines in winter, and spoils finished parts. A properly sized dryer solves those problems at the source. This guide explains how these systems work, the issues they fix, and how we size them. You will also see a clear maintenance schedule. By the end, you will know how dry air protects both your bottom line and your equipment.
Why Moisture Is the Enemy
Every compressor pulls humid air from the room. When that air is compressed, it holds even more water. As it cools downstream, the water drops out as liquid. That moisture then travels into your tools and products.
What wet air does to equipment
Rust forms inside pipes and cylinders. Pneumatic valves stick and fail early. In cold Alberta months, condensate can freeze and block lines. Industry estimates suggest poor air quality causes a large share of pneumatic tool failures. The fix is reliable, consistent drying.
Where moisture comes from
Alberta air carries moisture in every season. Summer humidity loads the intake heavily. Even cold winter air holds water that condenses later. Compression then squeezes that water out downstream. A dryer is the only reliable answer for this. Without one, the moisture simply moves into your tools and product. Pipes rust from the inside, and finishes suffer. Instruments drift, and sensitive controls act up. Air-powered machines lose both accuracy and speed. Clean, dry air removes those risks at the source. It protects uptime and product quality together. That protection pays off across the whole plant. A right-sized unit is a small part of the system. Still, it guards nearly everything downstream.
How Hankison Air Dryers Work
These refrigerated dryers chill the compressed air to near freezing. The water vapour condenses and drains away. The air then reheats slightly and flows to your system dry. The process is steady and energy efficient.
Dew point you can trust
A good dryer holds a stable pressure dew point across the day. That number tells you how dry the air really is. Hankison units are built to hold that target under load. You can read more in our overview of how air dryers protect your equipment.
Steady performance under load
Demand rises and falls through a busy shift. A quality dryer keeps pace without letting moisture slip through. Stable performance protects downstream filters and controls. It also keeps your process results consistent.
Sizing the Right Hankison Air Dryers
A dryer only performs when it matches your demand. We look at several factors before we recommend a model. The checklist below drives every decision.
- Peak and average airflow in cubic feet per minute
- Operating pressure at the dryer inlet
- Inlet air temperature after the aftercooler
- Ambient shop temperature across seasons
- Required pressure dew point for your process
Get these numbers right and the dryer runs efficiently for years. Our our refrigerated dryer range explain how dryers and filters work together.
Matching Dryer Type to the Job
Not every plant needs the same solution. The table below compares common approaches so you can see where refrigerated units fit best.
| Air treatment need | Typical approach | Best fit |
|---|---|---|
| General shop air | Refrigerated dryer | Most Calgary facilities |
| Very low dew point | Desiccant dryer | Outdoor or instrument lines |
| Particle and oil removal | Coalescing filters | Paint and food work |
| Point-of-use polish | Compact filter plus drain | Sensitive machines |
Winter Readiness in Alberta
Calgary winters test every air system. Cold snaps turn leftover moisture into ice. Frozen lines stop production without warning. A reliable dryer is your first defence.
Protecting outdoor and feeder lines
Lines that run through unheated areas face the most risk. Dry air keeps those runs clear in deep cold. Good drains prevent water from pooling and freezing. We plan for the worst week of the year, not the average one.
Maintaining Hankison Air Dryers
Good dryers reward simple, steady care. Skipping service raises dew point and wastes energy. Follow a basic rhythm to keep performance high.
A simple seasonal rhythm
Check condensate drains and pre-filters each month. Clean the condenser coil before summer heat arrives. Plan a full inspection once a year. For the manufacturer’s full product range and specifications, see the official resource from SPX FLOW. This routine keeps your air quality consistent all year.
Signs your dryer needs attention
Water downstream is the clearest signal. Rising dew point or a warm, straining unit also point to trouble. Short, frequent fan cycling can mean a dirty coil. Catching these early avoids a wet, rusty surprise later.
Keeping Dry Air Efficient and Reliable
Dry air should also be efficient air. A good setup adds little pressure drop. That keeps your whole system lean. We plan for both dryness and economy from the start.
Right-sizing saves power
An oversized dryer runs more than it needs to. An undersized one struggles and lets moisture pass. The right fit balances both concerns. We size for your real load, not a rough guess.
Reliable drains matter
Automatic drains remove condensate without wasting air. Manual drains often get skipped, so water builds up. Dependable drains protect the dryer and the lines. Together they keep performance steady all shift.
Planning for growth
Your air demand may rise as you expand. A unit sized only for today can fall behind. We consider your near-term plans during sizing. That foresight prevents an early upgrade.
Problems we fix fast
Even good dryers need help over time. The table below shows faults we handle often. Use it to spot trouble before it spreads.
| Dryer symptom | Likely cause | Our fix |
|---|---|---|
| Water downstream | Overloaded or iced unit | Resize or service |
| High dew point | Dirty coil or low charge | Clean, restore charge |
| Frequent cycling | Fouled condenser | Clean and inspect |
| Constant draining | Failed drain valve | Replace the drain |
Frequently Asked Questions
What do Hankison air dryers actually remove?
They remove water vapour and liquid condensate from compressed air. Refrigerated models chill the air so moisture drops out. The result is cleaner, drier air for your tools and processes.
How do I choose the right Hankison air dryer?
Match the dryer to your peak airflow, pressure, and inlet temperature. Oversizing wastes energy, and undersizing lets moisture through. Our team sizes the unit to your real demand.
How often do Hankison air dryers need service?
Check drains and filters monthly, and plan a full inspection each year. Dirty coils and clogged drains raise dew point and energy use. Regular care keeps performance steady.
Will drier air really protect my equipment?
Yes. Moisture causes rust, frozen lines, and failed pneumatic valves. Dry air extends tool life and reduces reject parts. It is one of the best investments in air quality.
