Cant recall seeing any.
It looks exactly like the one depicted on page 7 of the operator manual that icemeister posted the link to.

Cant recall seeing any.
It looks exactly like the one depicted on page 7 of the operator manual that icemeister posted the link to.
It just says "Digitraul"
Thanks for the info guys!
The controller that it has is the Digitraul controller as depicted in the owners manual courtesy of icemeister.
Unfortunately the Intela-Traul Service Manual does not...
Hey guys,
Could anyone be so kind as to get me a link to the service manual for a Traulsen blast freezer model RIF234HUTBF-FHJ ?
Not seeing it on there website.
The compressors on it indicate...
Yes Ice, they plan on changing the cases as well.
Yeah I think they would want minimal disruption to their operations considering its one of their larger stores.
I was looking at the Hill-Pheonix...
Hi Everyone,
I have a potential customer that wants us to do a refrigeration system changeout.
Currently they have 3 Hussmann Protocol units.
Model # PH05PK-MFMFMFMFMF
another Model #...
Otto8,
Glad to see that you solved the problem in the end.
However,I don't think that this compressor is a 3 phase unit with the amps that you are pulling.
That 5amp reading is probably the...
Hey guys,
I have a Delfield freezer model #6525 that a customer has asked me to look on. I realized that it has been worked on a couple of times.
The nameplate says it uses R404a and is a 220v 50...
Thanks Flange,I'll give them a call tomorrow.
Hi Everybody,
Does anybody here know if Smardt will train you as an individual ? Meaning you are not with a company that is a distributor for them ?
I will be in Canada around the time they have...
Can't even begin to comment.
YOU really did such an install despite knowing better ?
Judging from the pics it looks like they did an "open delta" setup.That's where they use two transformers and two primary phases to give you three phase secondary,perfectly acceptable as long as the...
Oh no,when I said fog I don't mean like wet condensation, I mean that between the panes of glass there is a solid white substance sticking to the glass. If you tap the glass you might see some flakes...
By virtue of fewer moving parts,scrolls should have the better reliability factor.It's just that once there dead there finished,absolutely no fixing of them
Thanks guys.
Do you all think that recip semi-hermetics are now obsolete especially in a/c apps.Most new stuff that I see below a certain tonnage now all have scrolls.And anything above are screws. I only see new...
Does anybody know why a glass door of a reach in would fog up.I have some units in storage that have gotten totally fogged up and some partially.They are not in operation and are stored outside.I...
No they are not cooling the outdoors.What they have done is to use the air handler coil as additional condensing surface.Dont know why,maybe the original coil is partially damaged,or maybe they put...
Well in all fairness to them ,the unit is located in a restricted area.I was just able to stick my hand around the fence to get a picture.But you're right it should have some kind of protective...
Followed friend to supermarket the other day.While waiting in the parking lot this was what I saw at the back of the building.Their using an air handler as part of the condenser.This unit is being...
This is exactly my belief too.
Her husband,who is my brother by adoption (mine by his father) has always been saying that I'm the one who is going to take over the business when they retire.They...
Quite so!!
She likes to say that she thinks I'm just a follower.
I think I was taught in school that great leaders were once great followers,just can't remember if that was a quote from some great...
Was having a discussion with in law who also happens to be one of the directors for the company that I work. She basically is of this opinion and does not believe otherwise.
I would like to hear...
I ve been using the Supco PR-90 universal potential relay.That's what all the supply houses out here have anyways.They work on anything from 1/4hp-5hp, 110-240volts.Just plug and play,nothing to...
All the mini-splits I know of (Mitsubishi,Fujitsu,Carrier etc)operate this way.You can set the fan speed to "auto" and it will vary the fan speed automatically as the unit approaches setpoint...
Man I love fried rice the best kind IS made from leftovers.
That bacon thing does sound like a dead man walking though.
Personally I like to microwave bacon in a paper towel to collect the oil.
I charged it by weight initially (16oz 404a) and let it run for about two hours, then I added more (not sure exactly how much) to provide cooling for comp as it seemed hot on the dome.Now the unit...
Quite TRUE on that one :D
Whenever I had to splice captubes,I usually use 3/16" copper about 1" long with the two captubes meeting in the middle. Make sure to blow Nitrogen through to make sure that tubes don't get plugged...
Dchappa,
The evap only has one fan. I'm hoping the low pressure switch will do its job when that time comes.The unit is going to operate in the lab where the ambient is70-75F. No I didn't take the...
Hi guys,
sorry to take so long to update you all.
Unit has been running for a week in the shop and has been maintaining design temp of 30degrees Celsius.
Here are the following temps and...
Forgot to mention the fact that I changed comp from copeland air cooled semi-hermetic to equivalent Btu tecumseh refrigerant cooled hermetic.
The accumulator is in warm air stream of condenser.
In...
Hi guys,
Is it necessary to insulate an accumulator on a low temp installation ?
I just worked on a blood plasma freezer that keeps the product at -30c. It has a top mounted condensing unit.
I...
Hey half the time I do this type of work in my shop :eek:
Wouldn't a 1.5cfm take 4 times longer than a 6cfm to do the same job all other things being equal ?
In other words,is there any lineararity...
I got the Veto xxl-f, just too lazy to pack it right now :o
Hey guys,
Apart from the weight of carrying, can a vacuum pump be too big for a job ?
I have a YJ 6cfm unit for a couple years now.I've used it on those little office refrigerators up to a 15 ton...
This is how they display the product temps of blood bank freezers and refrigerators (some kind of glycol for the freezers and sometimes water if not glycol for the refrigerators).Gives a very stable...
Yeah I figured as much.I'm going to try and get one that finds the leak before I even get the job :D
Hi all ,
has anybody ever seen a leak with say soap bubbles and not pick it up with an electronic detector ?
The other day I was working on a Panasonic cassette unit that I suspected had leak in...
If it's a mini-split with the expansion device in the condenser then the high side also gets insulated.If it's a normal unit with expansion device in indoor unit then liquid line is not insulated...
Hey I hoped you all observed the safe liquid level he was pointing out:D
Can't believe I just wasted my money on an Inficon recovery unit as well as cylinders :rolleyes:
Seriously though,kids...
Don't we all :D ?
Hi and welcome.
A pro will have to come in to determine if your present system is suitable and efficient for your needs.
They will have to do a heat load calculation taking into consideration the...
Those guys are damn lucky!!:eek:
People should never walk under a suspended load no matter how many years they have been doing it.
Looks like it was an old chiller though.
Excellent looking job :cool:.
Thanks to Tony and Andserco for the question and answer about the trap design.
A contactor with points that are marginal can cause a recurring burnout if not replaced.I have seen where one of the stationary points overheated to the point where the bakelite insulation or casing...
Compressors don't just burn up!!
That is just a symptom of an underlying problem.
Could be: high superheat,bad contactor,condenser fan motor cycling off on overload protection,dirty condenser just...
I would call it a liquid line,not a discharge line.Remember the discharge line is between the compressor and the condenser.
Typically most mini-splits I have seen have the expansion device in the...
I have the yellow jacket 68803 programmable scale.
It works okay,Ijust wish that it had the keypad,solenoid,scale,and power supply integrated into the casing like my old tif.It makes for easier...
Hi everybody,you have a great forum here!Learning alot just by looking at your discussions.Ive been in the biomedical field for the last 13 years.I spent about two years prior to that working in hvac...
