Re: Turbocor-Magnetic Bearings-Oil Free
Hi Guy,s
The turbocor compressor was designed here in Australia and is built in Canada as the aussie govenment would not give us a grant to manufacture it here.
The compressor is a two stage centrif, totally oil free with full mag bearings traveling on vsd drive up to 30,000rpm. they are solid state start at 2amp up to full current, cop at full load is around 3.5 but at 50% load the cop is 9 which is where real time engineering comes into play, most plants have two units sized at 66% of the total duty one run one standbye and the second chiller comes on line in the warmer weather or with increased demand for cooling which is normally only 10% of the year, the rest of the year one unit is running around 30%-60% load so the turbocor offers a far better power saving with a cop of 6 -9 at the part loads respectivley. the cost of a chiller is around 10% more expensive than a standard chiller but the power saving far outwieght the initial extra cost.
The compressors are only one third of the size and weight of a standard compressor of the same duty that is semi hermetic of course. the noise level is 75db @ 1m about the same as your carpet vac.
This is the technology of tomorrow guy,s.
Have a Nice day.

True, But now it is a 50/50 joint venture to be named Danfoss Turbocor.

Re: Turbocor-Magnetic Bearings-Oil Free
We spent some timer looking at these compressors for use with industrial process cooling. Process cooling runs flat out all year round; generally the compressors do not run unloaded. Currently we use the Bitzer screws and compared them to Turborcor.
Turbocor originally said it's compressors ran more efficiently than the Bitzer screws. Our information showed that the numbers were the same to the forth signiicant digit. Turbocor changed their attitude only after we showed them the numbers. There were no energy savings. Further our local codes meant that there were no installation savings. Both promised by Turbocor.
Their prices for new compressor matched the Bitzer screws when we compared similar sizes but Turbocor offered only one size that was sped up or slowed down to match other capacities. A real price difference showed when we compared replacement costs. It was cheaper to scrap the Turborcor and replace it with a Bitzer.
I understand, but don't know for sure, that their sales staff came from Trane. They certainly behave like it. They have got a good idea but their sales staff needs to learn that they are selling just another compressor not the only one.

And also,... you can't change nature laws so I'm always very sceptic when someone comes with THE solution. The only thing you can do in any cooling system is trying to come as close as possible to an ideal Carnot process.It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Make one small enough for a reclaim unit, if it can handle liquid would solve alot of downtime on jobs .

Re: Turbocor-Magnetic Bearings-Oil Free
This is not new technology as far as I am aware, just developed and adapted. In the scientists labs they use vacume pumps which spin at 80,000 rev/min. These and air bearings have been around for more than 25 years. Getting the oil out of refrigeration systems is the innovation. Who would want to work around one of those ear piercing noisy screw chillers? One other thing anyone can fudge the figures to make a particular product look good, take for example system COP and chiller COP - big differance

Re: Turbocor-Magnetic Bearings-Oil Free
Most of the problems with Turbocor compressors are caused by
incorrect software settings, either in the compressor and or
pid controller, when commissioning you must have the required
training and software.
They are a great compressor..

Re: Turbocor-Magnetic Bearings-Oil Free
Having worked for Star who are pushing these units, seen alot of problems and spoke to a few engineers who are of the opinion. They don't like light loads and the software is a mare! So unless you have money to throw at call outs and modifications stay clear. I made alot of money with call outs to these units!!!!!

Re: Turbocor-Magnetic Bearings-Oil Free
Out of warranty parts are very expensive, if commissioning is
carried out correctly, I have found most faulty components show
up in the first 6 months (covered under warranty)
Low loads used to be a problem but that is easily overcome
by using a well designed chiller (ie Powerpax)

Re: Turbocor-Magnetic Bearings-Oil Free
Hi the only real good comparment is at part load, where turbocor is extremly efficient,at full load the screw actully has a better cop!!!

Re: Turbocor-Magnetic Bearings-Oil Free
NO, Turbocor units - as mentioned by bigsk and goshen - cannot cope with those pressures also it only works with a low pressure differential between discharge/suction of 2.5:1
So unless turbocor do some radical redesign the will remain for R134a only.
Though you could use a turbocor on R134a with a cascade condenser to condense CO2 for pump circulated applicationsLast edited by Plank!; 29-05-2011 at 08:28 PM.

Re: Turbocor-Magnetic Bearings-Oil Free
Some magnetic-bearing suppliers for large gas centri. compressors, it's a matured technique. Optimized compression ratio is around 2.5/stage (3 max.) so Turbucor is only suitable to R135a and chiller application. Anyone know who made refrigeration centri. compressors with higher ratio for NH3, CO2, HCFC in MT and LT or cascade application. Taking away oil (and its problem) from refri. system is an interesting wish.

Re: Turbocor-Magnetic Bearings-Oil Free
dvtruc, magnetic bearings may be a mature technology but mostly they operate from large external control cabinets.
The turbocor unit is self contained in a unit that is smaller and lighter than the drive motor for a normal compressor. This is what really sells them for me.
I maintain dozens of them, so I have seen a few problems - mostly down to plant operating conditions, passing check valves etc.
In close to 5 years of working with them I've replaced 2 units under warranty, both were easily lifted off the chiller by 2 men and the replacement unit lifted into position with no need for lifting gear. Not at all bad for a compressor with built in 87KW drive motor

Re: Turbocor-Magnetic Bearings-Oil Free
Depend on motor power, magnetic bearing control is built-in or not. You can find at Synchrony a 400 kW motor with it built in.

Re: Turbocor-Magnetic Bearings-Oil Free
The best feature of the the Turbocor compressor is it has allowed a centrifugal to operate on air cooled applications with flooded evapourators, without all the hassle of oil return. Yes a screw can match efficincies at high condensing pressures & high load, but most chillers run part loaded most of the year. Also screws require minimum discharge pressures for oil supply or you have to fit external oil pump.
