Hailea HS-28A, the newer replacement model of HC-150A.
A even more cheaper cooling fan found in this model compare to the 150A. The major noise of this chiller is from the cooling fan. To try my best, I put some sponge tape try to reduce the vibration / case noise. No big improvement noticed. That sad.
Added some extra insulation to the heat exchange In / Out. And the evaporator coil is also untied for a little better air circulation.
