kW of Refrigeration to Ton

[Heinsen]

Hello All,
So I just want to confirm that the conversion from kW of Refrigeration to Ton is 3.516 kW = 1 Ton.

So for instance I have this German made water chilling unit that specs its:
Regrigation capapacity at 43 kW
Water outlet temperature at 15°C
Water flow rate 5m3/h
Fluid delivered pump pressure 3bar

Im looking at purchasing similar US made chilling units that are spec'd by tonnage or BTU/hr so my question is, is this then equivalent to an approx 12 Ton chilling unit?
Thanks

The kW to tonnage conversion is correct. However, there is more than just the tonnage to the specs. I would say provide the complete German spec to the US manufacturer and have them quote an equivalent.

Better yet, engage services of an experienced mechanical engineer.

This is what I came up with:
Acording to the KW it's = to 12 tons or 144,000 btu/hr so if Q = 144,000 btu/hr = 500 x 22 gpm x TD then TD = 144,000/ 11,000 = 13 *F so it looks like the water on is 72*F and water off = 59*F

Yes, 12.2 tons.
