The load on a refrigeration dryer doesn't just depend on the volume of compressed air to be dried (grey area), but more importantly depends on how much water the incoming compressed air contains. The volume of water (moisture) increases as the temperature rises, so the load on refrigeration dryers increases dramatically when ambient temperatures are high, such as during summer (yellow curve).
Conversely, when the temperature falls in winter (turquoise curve), there is less load on refrigeration dryers. To maintain a stable pressure dew point throughout all these fluctuations, refrigeration dryers should always be designed to provide sufficient performance during peak load times, and should also have additional capacity in reserve.
Like the flow rate and temperature range, refrigeration dryers are always operating within the load range of 0 to 100 %. Because SECOTEC storage control ensures energy is only used as needed across this entire load range, users benefit from exceptional savings.
