The cooling of 10 1KW UVLEDs with S&A CW-6300 water chiller

Normally, an S&A CW-6300 water chiller with 8500W cooling capacity is not sufficient to cool 10 1KW UVLEDs. But why S&A recommends CW-6300 water chiller to cool 10 1KW UVLEDs of President Zhang?
The efficiency of UVLED is very low regularly, but the efficiency of UVLED of President Zhang reaches 45%. So, only S&A CW-6300 water chiller can cool 10 1KW UVLEDs.
For another customer President Lin from Guangzhou, the efficiency of his UVLED also reaches 45%. He uses CW-6000 water chiller with 3KW cooling capacity to cool 4 1KW UVLEDs and uses CW-5200 water chiller with 1400W cooling capacity to cool 2 840W UVLEDs.
