China is not just the world’s biggest heat-exchanger market — it is its export engine. 2025 exports reached roughly US$8.9 billion, with the trade surplus up about 47% versus 2020. The first half of 2026 ran ~US$6.7 billion, up 15.8% year on year. Where it goes ASEAN — fastest-growing neighbour market for HVAC and industrial plates. Middle […]
Why Chinese Heat Exchangers Cost What They Do in 2026: A Pricing Teardown
“Why is it so cheap?” is the first question every overseas buyer asks. Here is an honest teardown for a mid-range plate heat exchanger. Cost structure (per unit) Raw materials 55–60% — aluminium (6061/6063) or copper, stainless plates (304/316), and gaskets (EPDM/NBR). Material cost is the swing factor. Labour & assembly 15–20% — brazing, sealing, […]
Plate vs Rotary Wheel: What Chinese Factories Are Shipping in 2026
Walk any Chinese HVAC factory floor in 2026 and you will see two air-to-air recovery technologies dominating the line: the fixed-plate recuperator and the rotary enthalpy wheel. They solve the same problem — recovering energy from exhaust air — with opposite mechanics. Knowing which one a supplier pushes tells you a lot about their target […]
From Copy to Co-Create: China’s Rise in Heat-Exchanger Patents and R&D
For years “Made in China” meant low-cost copies. In heat exchangers that story is ending. Industry reports put Chinese applicants at roughly 38–41% of global heat-exchanger patent filings in 2025 — behind only the combined EU/US lead on fundamental heat-transfer theory, but ahead on volume. Where the patents are going Microchannel aluminium cores for EV […]
How Heat Pipe Heat Exchangers Work: Passive, No-Moving-Parts Recovery
A heat-pipe heat exchanger is the quiet workhorse of air-to-air recovery: it moves heat from one airstream to another with no fan, no pump and no moving parts inside the core, relying entirely on the physics of a two-phase refrigerant loop. That makes it uniquely suited to dirty, greasy or contamination-sensitive exhaust where you want […]
Cross-Flow vs Counter-Flow Air-to-Air Heat Exchangers: Which Gives Higher Efficiency
When specifying a plate air-to-air heat exchanger, the flow arrangement — how the supply and exhaust airstreams meet inside the core — is the single biggest determinant of peak effectiveness and of how the core packages into your unit. Cross-flow (streams perpendicular) and counter-flow (streams opposite) are the two common arrangements, with parallel-flow rarely used […]
Pharmaceutical and Hospital Heat Recovery: Specifying Zero Cross-Leakage
How to specify heat recovery for pharmaceutical cleanrooms and hospital isolation rooms where cross-contamination is unacceptable. Plate, heat pipe, and run-around coil compared.
Frost Protection for Air-to-Air Plate Heat Exchangers in Cold-Climate Ventilation
In cold-climate ventilation, an exhaust-to-supply air-to-air plate exchanger can frost on the exhaust side when the supply outlet drops below the dew point of the humid exhaust. Frost narrows the channels, raises pressure drop and eventually blocks the core. Knowing when it forms — and which protection strategy to use — keeps the unit efficient […]
Commercial Kitchen Heat Recovery: Capturing Energy from Exhaust with Air-to-Air Heat Exchangers
Commercial Kitchen Heat Recovery: Capturing Energy from Exhaust with Air-to-Air Heat Exchangers Walk into any busy restaurant kitchen at dinner service and you will feel it: a wall of hot, greasy exhaust air being thrown out through the hood, while at the same time the make-up air unit is burning energy to condition cold outside […]
Plate Heat Exchangers: Types, Applications and Maintenance
Plate heat exchangers: how they work, gasketed vs brazed vs welded types, where they are used, cleaning and a practical selection checklist for engineers.
