Industrial-scale equipment sold to private owners
VEVOR’s pool line sits oddly and interestingly between domestic and trade. A 105.5 kW plate heat exchanger is not a garden-centre item; a 300 × 200 cm frame pool very much is. Both carry the same brand and the same listing format.
That format is specification-forward — kilowatts, vessel diameter in millimetres, pad size in metres — and it is usually complete on the numbers that size a component. What it rarely covers is the rest of the installation: a heat exchanger needs a heat source, a circulating pump and a control strategy, and none of those arrive in the box.
One frame pool listing in this catalogue states a volume in its title that its own bullet list contradicts by an order of magnitude. That is reported as published. An owner who orders liner volume from a title figure would buy the wrong quantity of everything.
450 mm tank, 151.4 l/min (40 GPM), 7-way, drain plug
The only system here that publishes its tank diameter — 450 mm — with flow given in litres per minute and in US gallons per minute, and a drain plug for winter.
Best for: Somebody sizing a bed by area rather than by headline flow
