Description (English):

ISO 7183:2007 specifies the performance data that are necessary to state and applicable test methods for different types of compressed air dryers. It is applicable to compressed air dryers working with an effective (gauge) pressure of more than 50 kPa (0,5 bar), but less than or equal to 1 600 kPa (16 bar) and include the following: adsorption dryers, membrane dryers, refrigeration dryers (including drying by cooling) or a combination of these. A description is given of the principles of operation of the dryers within the scope of ISO 7183:2007. ISO 7183:2007 identifies test methods for measuring dryer parameters that include the following: pressure dew point, flow rate, pressure drop, compressed-air loss, power consumption and noise emission. ISO 7183:2007 also provides partial-load tests for determining the performance of energy saving devices or measures and describes the mounting, operating and loading conditions of dryers for the measurement of noise. ISO 7183:2007 is not applicable to the following types of dryers or drying processes: absorption dryers, drying by over-compression and integral dryers.

Abstract

Overview

ISO 7183:2007 - Compressed-air dryers - Specifications and testing - defines the performance data and test methods required to specify, measure and compare commercial compressed-air dryers. It applies to dryers operating at an effective (gauge) pressure greater than 50 kPa (0.5 bar) and up to 1 600 kPa (16 bar) and covers adsorption dryers, membrane dryers and refrigeration (cooling) dryers, including combinations. The standard describes operating principles, reference conditions (e.g., 20 °C, 100 kPa reference), standard rating parameters and required test procedures for key dryer performance metrics.

Key Topics

Scope and exclusions
- Applicable to adsorption, membrane and refrigeration dryers.
- Not applicable to absorption dryers, drying by over‑compression or integral dryers.
Standard rating parameters
- Defines how to state rated flow and ambient/inlet reference conditions so dryer comparisons are meaningful.
Performance tests and required data
- Pressure dew point (measured at outlet and at rated flow in accordance with ISO 8573‑3).
- Flow rate and outlet temperature.
- Pressure drop across the dryer.
- Power consumption and electrical/energy metrics.
- Compressed‑air loss (purge, permeate, blow‑down).
- Noise emission, with mounting and measurement conditions specified (Annex C).
Partial‑load and energy‑saving tests
- Provides test methods for partial‑load operation to evaluate energy‑saving devices and control measures.
Test arrangement and reporting
- Specifies test rig arrangements, instrument accuracy, uncertainty considerations and required test report contents (including a report form in Annex B).

Applications

ISO 7183:2007 is intended for practical use by:

Manufacturers - to publish standardized performance data and ensure consistent product specifications.
Test laboratories - to perform reproducible performance and noise tests for certification or validation.
Procurement and specification engineers - to compare dryers objectively when selecting equipment for industrial compressed air systems.
Facility managers and energy auditors - to evaluate dryer energy performance, partial‑load behavior and potential savings from retrofit devices.
Designers of compressed‑air systems - to size dryers, assess pressure drop impacts and specify dew point requirements for processes sensitive to moisture.

Using ISO 7183 helps ensure reliable moisture control, lower operating costs, predictable pressure loss and compliance with accepted testing methods when selecting or verifying compressed‑air drying equipment.
