United refrigeration in Worcester will be able to bring you in alco parts but they are always a few days out.

Johnstone supply stocks some Alco parts

Also Bell Simons on cambridge st in...

So after they fixed a leak and recharged the system you started getting high head problems?

Do you have a filter drier and is it located before the sightglass? Its probably plugged up and thats...

Also higher head pressures will increase the compression ratio of the rack increasing KW per ton.

I can't remember who told me this so I don't know how accurate this is but I think for every 1psi...

Always drill.

And don't be that guy when adds gauge fittings uses the 1/8th inch fittings and they break off if you bump into them or snap off if you need to change a shraider.

That only makes the problem worse when all the fins start falling out.

I have a system that uses a Sporlan EEV for an expansion device for the subcooler. It is an SEI-11-10-S valve. It uses the Sporlan subcooler controller which I believe is the source of my problem,...

There ya go...
No need to worry about overheating your windings...

All of my low temp R22 racks have an accumulator for the entire rack.

A few of my Hill/Pheonix racks with 404 or 507 also have an accumulator but only for the satellite compressor.

Not sure why...

Every hot gas defrost system needs to have an accumulator or else it will flood back liquid to the compressor.

I think the "TSK" nomenclature is found only on 4D models.

The only possibility I can think of, is possibly this compressor is a discontinued model but by looking at that model number it doesn't...

Most racks don't need accumulators. Suction header should act as one.

Also, I don't think I have ever seen an accumulator on a Rack with electric defrost.

I work with a guy who gave his 10 year notice, seven years ago.
He will be done 10 years to the day he gave his notice.

I think there are several formats for the test. When I took the test a few years ago there were quite a few questions on dates, probably 1 in 5 questions was a question on a date.
I think its very...

I went to refrigeration school right after high school and when I got out I thought I knew it all.

The first day on the job and the first rack I worked on had high speed direct drive 5H60's. ...

I had one of those days where everything goes wrong and I made the same mistake with a unibit into a 5/8 liquid line.

Is that an old Hill Rack?
They run great when there's gas in the system.
I have 3 of those racks we piped together to make the "6 pack" rack.

I'm glad to see you've already got the bag of...

That problem may be isolated to the compressor not to the oil system as a whole.
Have you cleaned any screens on your oil pump or oil press transducer? How do the contacts looks on the compressor...

It just needs a little tender loving care then it'll be good to go.

Don't overload your van. The shelving in the fords is terrible. My shelving came crashing down about 2 weeks ago. I thought someone hit the van, definitely ruined my day.

I recently found a 25psi pressure drop across a suction filter on a R22 system. Rack was running at 100% capacity and couldn't make target suction pressure. The filter looked like it was soaking in...

Does that compressor on the left have an oil safety control?

Despite what Obama is going to tell us, we saw the real state of the union last Tuesday when we elected Scott Brown.

I think that sums up exactly what people are thinking right now. We need to...

What needs to be done right now is that registered Democrats AND registered Republicans need to become un-enrolled/ independents. If the voter registrations dropped from BOTH parties, the two...

The problem with 3rd party candidacies is they split the vote of the republican party.

For the most part, every vote for a 3rd party candidate is a vote that would have gone to a republican.
