Scope of GB/T 21087
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.
What It Specifies
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.
Why Buyers Should Care
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.
Selecting a Compliant Unit
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. Contact us for a GB/T 21087-aligned recommendation, or email kuns913@gmail.com / WhatsApp +86 15753355505.
Frequently Asked Questions
What does GB/T 21087 cover?
China’s GB/T 21087 specifies requirements and test methods for air-to-air energy recovery devices including plate, rotary, heat-pipe and run-around coil types.
Why does GB/T 21087 matter for buyers?
It is the baseline compliance mark for devices sold in China and a useful specification reference for global buyers sourcing from Chinese manufacturers.
Effectiveness grades and export notes
GB/T 21087 classifies devices by recovery type and rates sensible (and, for enthalpy units, total) effectiveness against defined test conditions. For export equipment, treat GB/T 21087 as the Chinese baseline and pair it with the target market mark CE/EN 308 for Europe or AHRI 1060 for North America so the same core can be documented for both. Confirm the test report covers your operating airflow and the moisture-recovery clause if your application needs it.
