Trane definitely...but I'm a little biased.

the Flugger Valve Company dabbled in screw machines YEARS ago but they made them too good...never did fail and no replacement parts were neccessary so they stopped making them. too bad really. I would love to have had the opportunity to rebuild just one of them. all of them are still running today from what I hear.

Why are Carrier chillers overlooked when these questions come up. Kinda like the fat kid that gets picks last at a dodgeball game.

Time will tell Grasshopper some people may not know Carrier makes a screw chiller since there aren`t many in the forum being worked on ,on a daily basis,but I could be just bias.:pop:

All the big companys make screw Chillers and all have good and bad issues just a matter of which ones you want to deal with the most. JMHO

I'm bias too. Carriers problem is getting salesmen with a clue.
Sell it to be installed correctly and get trouble free operation. A 30HXC with pump control, condenser water bypass valve controlled by machine, 3-6 gallons of water volume per ton, cooler flow 2.4 GPM per ton, and condenser flow 3.0 GPM per ton will be trouble free. Install the machine under the old sequence of operation design and Carrier gets a bad reputation.

Now is the best time for them like buying a new car model that's been out for years the bugs have been worked out. Or new this year 30XW has the same design with a larger quieter compressor with a beefed up slide valve design for capacity control.

We still make 23xR Centrifugals. We won't carry a full maintenace contract on the obsolete XL (e"X"tra "L"abor) machines due to the old slide valve issues. The new 30XW compressor is like a smaller beefed up version of the 23xL compressor mounted on a chiller designed like the 30HX. Less noise higher capacity range.

I've used the Versatec (VXV030) since the house was built in 2002. The only issues I have had with it are due to the open loop. When it is super cold out the unit has to flow anyway or the discharge will freeze up and the unit will thermally cut off. It works w/o the em heat until it is below 5 degrees F for several days. I have a separate wood stove for the backup, the 8kw backup is still in the box :) I also have the desuperheater setup. I think I've been saving money, but as it was a new install in a custom house there is no really sure way to check, but if the propane truck going to my neighbors is any indication, I think I am still ahead ;) Consumers Energy bill averages about $200 / mo for all useage in the house kept at 73-74 year round
