I might be mistaken but the Danfoss/Maneurope compressor is the original Trane Cornerstone one compressor.......used to be the orange compressor.....Danfoss paints it blue.

The Trane Cornerstone...

Unfortunatly AAON and problems are a redundant statement. The units are notorious for wiring errors and voltage drop at the contactors. Upgrading the transformer is a first step and going to the cube...

WSHP's should have a 12 degree rise in cooling across the condenser and a 6 degree drop in heating. This is at ARI flow rates....McQuay catalogues entering water temps up to 110 EWT. This application...

Is this unit a upflow or downflow? Data-Aire had many problems with evaporator airflow at the time of this unit.

The slab coil arrangement they used back then was horrid on airside pressure drop. ...

A simple test for proper flow is you should have a 12 degree rise in water temp in cooling and a 6 degree drop in heating.

Dectron is ok, but somewhat over priced and difficult to service. 15 tons and under I would go with Desert-Aire..they have been around since late 80's very releiable stuff.Milwaukee Wi. company...

Hey Outside Rep...good luck with Artichill and the Turbocores. They had to turn back a large order in Indianapolis about 4 months ago. Also I understand that Artichill is in patent litigation for...

BSC = Baltimore Spot Cooler....went sunnyside up 10 to 15 years ago.

Then I would go with 3- 20 ton modules which would have the -20 ambient flooded recievers . This would give you 6 steps of capacity control and the ability to unload to 10 tons.Use the existing fluid...

The fan speed option may allow the chiller to run at 0 degrees but can be a problem starting at 0 degrees. Especially with a low load....You may add a small fluid cooler into the system for...

Dear Serverroom,

Approx. 32 pages ago (give or take a hundred) I warned you about dealing with APC for coolng solutions. I doubt you will ever get a unit since word has it that they are getting...

The original question was which chiller was most efficient.

The best efficiency I have ever seen is a McQuay dual compressor centrifugal with a full load kw/ton around a .54 with a IPLV about .31...

We always recommend 70 degree loop temp in winter (avoids nuicance trips on low temp) and stage 1st stage heat of rejection at 88 degrees with a 2 degree deadband....

The unit you guys are talking about is called a water cooled verticle self contained unit the uses condenser water to remove the heat of rejection. Most applications are VAV which means the unit has...

Hokey smokes Bullwinkle, how about we subtract the diameter of the sphinkter valve by the circumphrense of a dogs nose...will that work!!! put a fork in it!!

If you cannot find any data on the existing models I would suggest measuring the height and length of the coil and overall cabinet and compare that to new models. There has been no new technology on...

I understand your frustration serveroom...my summary did not intend to cover all points of view.just commentary..but you have a point....lot's of HVAC guys including engineers do not understand the...
