- GB/T 21087 is China’s national standard for air-to-air energy recovery devices. It covers the common recovery types used in Chinese and exported equipment: plate (recuperative), rotary wheel (regenerative), heat-pipe, and run-around coil systems.
- The standard defines classification, technical requirements, test methods, inspection rules, and marking or labeling. It is the baseline compliance mark for devices sold in China and a useful specification reference for global buyers. China is also a major manufacturing base for these devices; see our notes in the Encyclopedia on air-to-air recovery manufacturing clusters.
- Specifying GB/T 21087 compliance helps ensure a device meets defined effectiveness and safety requirements rather than unverified claims. For moisture recovery, confirm whether the standard’s total-effectiveness test applies to the unit you are buying.
- Match the device type to the air streams: separated plate cores for dirty or contaminated exhaust, wheels where moisture recovery is wanted and carryover is acceptable.
