60TR Chiller Power Consumption

What voltage? How many phases?

Voltage: 3 phase, 400 V, AC

Look at the chiller rotary disconnect switch or the internal main fuses or breaker.

Size according to these. This unit should have some type of service disconnect

for workers. The prints will also have the amperage listed for this unit.

Good luck,

James

Presently I don't have a 60 ton chiller to look at the power consumption of it. I need this information to design a MCCB rating and Main supply capacity of a particular building, so if you can pl help me to find out the MCCB rating.

The manufacturers' data from appropriately-sized machines should be all that is needed.

Excellent. You hit that nail with a sledge hammer!

I have not heard about 60 ton chiller till now . I think u r referring to the catalogue code i.e 60TR which means 6 ton chiller. Most of the companies manufacture chillers from 4,5,6,7 upto 15 tons respectively .

For 6 ton Chiller the parameters are as follows

1. Normal Volatage range = 342 -455 V

2 . Mimimum circuit ampere = 16.3 A

So we use 20 A MCCB

Compressor type is Reciprocal

we can use 10mm2 Cu cable

Dear ll,

Thankx for your valuable support.

Most of the companies manufacture chillers from 4,5,6,7 up to 15 tons respectively

No no, You may talking about Scroll compressors, Max capacity of 15 Tons, That can't be a chiller. There in the Market you can get Max of 15 Tons scrolls compressors. There is a wide range of chiller 2 ton to 6000ton (Vapor compression/ Electric Drive)

Be very careful, as 60TR capacity is unknown at this point. As "ED" has pointed out, the 60 in 60TR could mean anything from 6 to 60 to 600 to 6000 ton or it could be the 60th TR model produced. Cable siz could be off by a factor of 1000!

What is the capacity of the 60TR? Who is the manufacturer? Who is the salesman who sold the unit? Ask him for manuals. Who is the engineer who specified the unit? Ask him these questions.

Hi,

By 60TR do you image 60 tons of refrigeration ??????

We can help you on this but still we must know more information of your application,

Type of chiller( Scroll, Screw, Air Cool Water cool Etc,)

Primary power supply

Ambient condition

System water flow details.

Expecting Temperature range. Etc.

At this moment, I do not even know who manufactures the "60TR", so I don't know what I should imagine. As you and others have noted, without better capacity numbers, someone could either seriously oversize or undersize the MCCB or cable sizes and get into trouble.

As long as nobody is spending money or real labor, I can make S.W.A.G.s (Scientific Wild A-- Guesses) as well as anyone. I want to get cautious when real money and effort will be spent.

Dear all,

Thank you again for your valuable help. Here I'm suppose to design electrical installation of a particular project, so i have to allow provision for A/C as well. In this bidding document specifications they have mention the size of the water cooled central A/C system as 60 TR, so I thought they are referring to 60 ton chiller. The floor area of that particular premises is around 10,000 sq ft.

Talk to your mechanical engineer. Honest, we do not eat electrical engineers for lunch. We save them for breakfast the next day!

He should be able to give some idea of the electrical requirements of the equipment he selected.

Dear Madam

we are required only output of Chilling water for 70TR chiller
