Why isn't a dryer selected by compressor capacity sufficient?
The most common mistake: a dryer is chosen based on compressor capacity, period. In reality, the capacity specified in the dryer's passport applies only under ideal conditions — +25°C ambient temperature, +35°C inlet air, 7 bar. In Georgia's summer, in a hot machine room, the actual capacity drops by 30-40%. Result: a dryer that is 'sufficient on paper' cannot handle the moisture, condensate passes into the system, and pneumatic tools, valves, and products are damaged.
Correction Factors — What the Calculator Takes Into Account
Ambient Temperature: The hotter the room, the harder it is for the refrigeration circuit to dissipate heat (at 45°C, capacity drops by ~35%). Inlet Air Temperature: Hot air carries more moisture — every +5°C significantly increases the load. Working Pressure: At low pressure, the air is 'fluffy' and more volume passes through the dryer. The calculator multiplies all three and gives you the minimum required capacity for both dew points (+3°C and +7°C).
Frequently Asked Questions
+3°C or +7°C Dew Point — Which Should I Choose?
+3°C is standard industrial quality (ISO 8573-1 Class 4) and the right choice for most production. +7°C is an economical option for simple tasks in warm rooms. If you need −20°C or −40°C, a refrigerated dryer won't help — an adsorption dryer is needed; our Air Purity Configurator will tell you which class you need.
What happens if the dryer still can't handle the flow at 'peak'?
For short-term peaks, a correctly selected receiver before the dryer is sufficient — it smooths the flow. Constant overload, however, can only be resolved with a larger model. See the full range of air dryers or contact us — we will help you with selection for free.
