Have you considered a "Bard" wall mounted unit such as is used on mobile jobsite trailers? You will probably have to build something to hide it, but that shoudn't be a problem.

Turn it off?

Have you tried, Trane, York, Carrier, or McQuay?

All of these companies have service groups.

Check out this site. It has helped me thru some rough times.

Good Luck and God Bless

Does this system have glycol in it? If so, was the coil designed for glycol?

You won. Where do I send the money?

You may be on to something with the low control voltage. It is very possible that the coil is not drawing in as quickly/firmly as it should.

Another thing I would check is your cycle time between...

What model chiller? RTAA or RTAC?

How many compressors in the machine (not sure from your post)?

What are the operating pressures and temps for both compressors.

Are the compressors running...

Anything is possible.

Could it have been short cycling on low pressure due to the coil being iced up?

Could the compressor have been slugging liquid refrigerant and overheated the motor?
...

I will add that on a flooded condenser the cooler entering water is in contact with the condensed refrigerant before it flows to the evaporator. It is because of this that you can have a negative...

The approach temperature is determined by the design (from the engineers) of the machine and is dependent upon the type of machine in question.

The evaporator approach on a centrifugal chiller...

Depending upon the age of the AHU, a 10 degree water side temperature rise is a fairly common design, but in recent years I have seen 12, 14, and even 16 degree design rise thru the coil.

If you...

The year is 2222 and after accumulating enough frequent
flier miles, Mike and Maureen land on Mars. They meet a
Martian couple and are talking about all sorts of things.

esornivram, I think I have one of these units with the problems you have described. Who should I contact to get authorization for repairs?

Anyone had experiance with Advantage contactors in a unit mounted starter blowing up?

Go to Sporlan's website.

Welcome christine.

Have you checked the actual temp at the condensor sensor with an accurate temp probe and compared it to what the readout on the panel? With the subcooling that you have (40 degrees) it is likely that...

First, let me say that you really need to read the IOM on this machine to truly understand how it operates. Second, you must not try to troubleshoot the machine without having your gauges hooked up....

Is it "Rats" or "Rates" that you are afraid of.

I can tell you that there are a lot of "Rats" in this buisness, but most of them walk on two legs.

Most, if not all, professional technicians expect benefits or an equivelant additional compensation to cover the costs of purchasing insurance and putting away money for retirement.

I wonder if...

Payson, I have been reading your threads for a while now and agree with truck31. I think you would do well in commercial.

Contact the Trane CSO (commercial sales office) in Phoenix.

Do not be...

There has to be a balance. Techs have lives too.

Is this a unit mounted starter or remote? What brand of machine? Does the starter have the intregal circuit board for the coil?

The most important things to me when hiring a tech is do they have a thorough grasp of the basics. That is, do they "really" understand the refrigeration cycle and the operation of all the components...
