HVAC & Heating Products Sourced from China
1 resources tagged with "Hvac Heating"
China is the dominant OEM source for steel and aluminium panel radiators, with the EN 442 standard governing heat output ratings and dimensional tolerances for the UK/EU market. Most factories cluster in Hebei and Zhejiang, with typical MOQs of 300–500 units per size and FOB lead times of 30–45 days. Watch for radiators rated to nominal Delta-T 50°C in older catalogues — EU tenders now usually require Delta-T 30°C figures, so confirm which the quoted watt rating uses.
When sourcing HVAC and heating hardware, the real risk is mismatched EN 442 test conditions and inconsistent paint/weld quality. We verify the heat-output certificate against the actual Delta-T, check the powder-coat thickness, and pressure-test a production sample before shipment.

FAQ
What certification do panel radiators need for the EU?
EN 442 is the core European standard covering heat output, pressure resistance, and dimensions. Most reputable Chinese OEMs hold CE marking referencing EN 442, but always request the actual test report, not just a logo on the datasheet.
What is a typical MOQ and lead time for OEM radiators?
Expect 300–500 units per size/model as a starting MOQ, with 30–45 days production once the deposit clears. Custom colours or branded packaging can add 1–2 weeks.
