The device allows stable and infinitely adjustable compressed air flow, pressure, temperature,

moisture content and other parameters.

01 The unit is divided into four sub-modules

        The above picture shows a part of the device, which is a modular frequency conversion oil-free air compressor system. The device adopts aluminum frame structure, equipped with multi-head oil-free scroll air compressor, each head adopts one-to-one control by frequency converter, centralized controller automatically distributes the load, the whole oil-free, small volume, low noise, and at the same time, through the switching bypass valve can be switched to provide room temperature or high temperature compressed air.

      The unit can be operated independently to provide a specified flow of compressed air.

     As shown in the figure above from left to right are devices two, three and four. Device two for the air supply buffer tank, device three includes chilled water regulation system, compressed air pipeline valve, compressed air exhaust buffer tank and the central control system and other units, device four includes a variety of switching valves, heating systems and drying systems and other units.

      The whole is divided into four small modules, each of which carries out a different function.

02 This device is used for testing of different devices

This device with the ambient temperature adjustment and other devices can be used for 

different equipment testing respectively.

For example, wet saturated compressed air at 10~60℃ is suitable for some of the following 

scenarios:

Routine load test and extreme overload test of cold dryer (with ambient temperature adjustment device)

Simulation of dynamic adsorption curves of adsorbents

Performance test of heatless/heated modular dryer

Performance test of a blower-heated regenerative desiccant dryer.

Extremely dry compressed air from 30 to 200°C can be used for some of the following tests:

Simulation tests of heating regeneration in heated/blast-heated dryers

Blow-cooled regeneration simulation tests on blast-heated dryers

Regeneration simulation test of heatless dryer

Cold/hot fatigue testing of precision pneumatic components

Comparison of dew point meter results

Unsaturated compressed air with adjustable moisture content from 100 to 200°C can be used to simulate high-temperature air compressor exhaust and is widely used in testing processes, for example: 

Compression heat regeneration adsorption dryer machine performance test

Thermal regeneration simulation test of compression heat regeneration adsorption dryer

Performance test of air-cooled/water-cooled after-cooler

Temperature resistance test of paint/rubber/seal and other components

Valve fatigue test under thermal load

Pilot test gas supply system

All in all, the device solves the various compressed air requirements involved in equipment development and provides excellent hardware conditions for Risheng's R&D test work.
