Anyone using JBJ Artica commercial unit?

[LittleBurger]

Has anyone used this before? Is it noisy? How is it compare to JBJ 1/2hp unit n commercial 1/2hp unit?

Am using a teco tr15. Am looking at teco tr20 or JBJ commercial unit 500B.

Consulted my CO n installing a compressor unit at living room window is OOQ. There's no way to install the compressor at my service balcony n route it all the way to my tank too.

Thanks.

TR20 is good enough for your tank size for temp around 26degC

super efficient but super noisy haha

do u have experience on a 1/3hp chiller used on a 4ft tank aka abt 600 liters of water takes how long to cool down 1degC?

my current temp setpt is 27.5. it start to run when thermostat shows 28.5deg. takes abt 1.5hr to cool to 27.5. is this normal?

not sure if anyone experiment n record down the chiller ramping time n calculate if the energy efficiency rate is linear.

eg. if u keep increasing the chiller hp and will it reach a point whereby increasing the hp does not really translate to energy efficiency. instead choosing an optimal hp will give more bang for Buck.

u using one of the jbj commercial unit? the 1/2hp looks nice. the size is quite small too.

I've used jbj online chiller selection auto calculation.

tank volume 115gal.

sump volume 35gal.

actual current water temp is 92F

desired temp is 80F.

not sure how much heat from lights n return pumps. So I just put 130watts for light n 120 Watts for return pumps. power head which is vortech I put 0 Watts.

strange tat the website recommended 1/5hp chiller.

is this correct?

thanks!!
