Desiccant Air Dryer
It is a best practice to include a desiccant air dryer as part of your compressed air system if your compressed air is exposed to temperatures below 3ºC ,or your product, or process, is extremely moisture sensitive. Desiccant air dryer capital costs are an important consideration, however the bigger concern to investigate will be the cost of ownership, particularly when heatless dryers are an option. Typical purge losses from heatless dryers can amount to as much as 15% of the throughput capacity. With Kaesers full range of varying purge loss options, we can reduce this loss to as little as 1%, and our energy saving, management control system, EMC, will further reduce energy loss and waste.

The System
When compressed air quality specifications call for pressure dew points of -20ºC (-4ºF), or lower, (ISO quality class 1), a desiccant style compressed air dryer is required.
There are 3 types of desiccant air dryers, and these differ by virtue of the way they regenerate their desiccant media. The least expensive capital cost dryer type is a heatless one. The heatless dryer will consume approximately 15% of the total air passed through it, so the cost of ownership will be the least efficient and most expensive. Heated style desiccant air dryers have a slightly higher capital cost, but the purge loss is approximately halved to only 7% and operating costs are improved compared to heatless dryers. Typically, the most expensive capital expenditure will be the blower purge style dryer, however the operating energy costs will provide a favourable ROI compared to the other styles of dryers. Be sure to invest wisely in your pre filtration, as the desiccant cannot tolerate oil carryover contamination. With the correct pre filters, the desiccant should last 5 years.

How it works
Our tried-and-tested approach to get you a reliable compressed air solution at the lowest possible cost of ownership looks like this:
Discovery call
Our solutions specialist visits your facility to discuss your current situation, pain points, future plans, and potential government incentives. We can undertake as little, or as much, of your project as you would like.
Requirement analysis
We analyze the compressed air equipment at your facility, its performance, condition, and suitability. We ensure that storage, piping, and compressed air quality are in line with your requirements and best practices.
Turnkey installation
Everything we do is “in house.” Air audits, leak detection, design, build, and service are handled quickly and efficiently.This approach means that we manage every aspect of your project, avoiding finger pointing and single source supply for you and your organization.
Maintenance and repair
Whether you require emergency breakdown response, predictive, or preventative maintenance our team has you covered. Air end and motor service and rebuilds, piping, and analysation are also available.

Air Compressors for sale
Our range of air compressors includes reciprocating piston, oil free, and oil injected rotary screw air compressors, from 3hp up to 660hp, and everything in between. If you do not know what you are looking for, we can assist with that too.
Filters
If you are looking for assistance in the filtration of dirt, oil, water, bacteria, hydrocarbons, oil odor or vapor, we have a filter, or an element to capture whatever you need to stop. Compressed air, gases, liquids, ambient air, and water filtration is what we do best.
Tanks
Horizontal and Vertical air receiver storage tanks are available, with the most common sizes kept in stock at our Hamilton warehouse.
Condensate Management
Disposing of the compressed air oil/water condensate bi product, created by your compressor station, carries big legal, and environmental responsibilities. The person knowingly discharging oil to drain, is responsible.
