sabroe overheat smc 112 L

[engrp]

hello fellow members. just registered here at re. we just purchased a sabroe smc 112L and are encountering overheating of the unit , resulting in the compressor shutting down. maybe you could recommend some reading materials which colud help me with our problem. our immediate ,easure to prevent compressor overheating is to dump the return water to the basin of the cooling tower. thanks

Welcome engrp.
Basically there are 2 main reasons for the head cooling water overheating.

1) worn discharge valves resulting in higher than normal head temperatures.

There are several other things that can also give this effect.

But the above is the most common.

2) Poor flow of the head cooling water across the heads..
Resulting in high head temperatures due to lack of cooling.

Several things can cause this ...

Pump Failure ( I presume the cooling water circuit is pumped)

The more common issue arises when the cooling tower water is used to cool the heads. Is Chemically
treated,

When the heads get hot and the flow rate drops off.
The dissolved solids in the water come out of suspension..

The resultant grey sludge clogs the water cavities in the heads...

Further reducing the cooling effect and causing more dissolved solids to drop out of suspension...

A vicious circle...

TO SUMMARISE..

Look at whether it's Mechanical or poor heat absorption..

Either of these May be the cause???

Just an after thought .. you are actually seeing high discharge temps and it's not the temp stat at fault??

thanks for the reply, grizzly. anyway, defect was traced to restricted water supply. thanks again.anyway, how do i post a new message ? i can't get to the blank message board

[engrp]

may i also ask if you can point me to a website, or can any of our fellow members share a manual for an old frick 9 x 9 compressor ? we are still using 2 of these units. thanks

What's the Model no?
I don't recognise 9x9
It is usually expressed as 2 or 3 letters!
I might be able to help.

greetings, again. grizzly. i am referring to the old style reciprocating frick compressors, which may be older than you are.i will attach a picture of the said compressor. i will send in a separate reply, once i get to know how to attach a picture. thanks again

engrp,
Try GNQ they might have manual for your compressor.

Hi, engrp

try here...

Go to http://www.frickcold.com/Products.as...lay=30&View=ON

They have a great deal of literature online.

I don't recognise 9x9

It's the modern version of the avatar you use grizzly.

A 9 X 9 compressor usually consists of 2 vertical cylinders that have a 9" bore & a 9" stroke. The are single acting compressors, where your avatar is probably double acting (compresses on both sides of the piston stroke).

Hi Engrp,
series HDI ?

Hi engrp,

I will have to hunt through my old documents. Maybe I can locate the Frick 9 x9 catalog. I remember it had the complete series of 4 x 4 etc. These used to be very much in use in the 60's with ammonia refrigerant. They were very efficient. These compressors were what Iceman has described. It is the bore and stroke in inches.

Samarjit,

The link you posted goes directly to a different website??? Can you provide some more detail on where to find this document please?

Thank you.

I do not know how this is happening. I shall download the file again and post it.
