Hello sir, just buy the S&A CW-5200. Has 6L water tank + 12L/min strong pump. My unit came with Hitachi rotary compressor + R134a. Some come with R407c. Can go down to 1°C or run in intelligent mode keeping a delta from ambient.
Look for the one from TEYU (China). Pricing is very fair imho for $600 + shipping
Regards
They sell units for 120/240V 50/60Hz. This is a much better purchase compared to Hailea Chiller, since those don't have a pump.
