GUYS:

The control principle of the TRANE brand is the same in the American RTAA, RTWA (with R22) models and in the TRTA TRTAB (R-22) and RTWB, RTAD (R134a) models.
They are direct expansion...

What oil pressure does the compressor have?
What are the cold water temperatures?

condenser inlet and outlet temperature?
discharge temperature?
suction pressure/discharge pressure?
remember that these machines do not have an oil pump and the lubrication is by differential...

good morning guys: you have to update the ch530, windows is not the problem, the pc i have has the W11 and it connects without problem, it should be clarified that it is DELL

DOES IT HAVE EXTERNAL OIL COOLER?

OIL TEMPERATURE? CONDENSING SAT TEMPERATURE?

check the menu cap.d in the mode menu there is a condition that does not allow the compressors of system "a" to start: such as low saturation temperature

morning guys:


I have a low superheat problem on an ERTWB trane chiller!

ANY IDEAS ?

Check the conditions of your compressor contactors, with a sheet of paper between them energize the contactor (you have to remove the compressor cables) and note if they close evenly, unusual wear on...

The machine is centrifugal, CARRIER brand, it is used for process with design temperatures in the condenser of 90/108 ° f, the model is 19XR7070557EKS64, currently the water has temperatures of 75/79...

good afternoon, guys :

Could someone support me with the following:

how many gpm are required per TR in the condenser and evaporator?

the team would be for process

only the...

STAINLESS STEEL TUBING

high oil level

Can you support the instructions?

morning guys:

I want to know if service tool 2.2 is compatible with window 10?

I have to download some patch?

Thank you

good morning
The problem with this alarm is that the oil solenoid does not seal for the pre-start

the high level alarm high pressure and high temperature oil and seen the high level of oil

chillmac:

what is your email?

the oil level is checked with liquid sight glass 1/4 "as stated in the manual.

oil bearing this machine is OIL0015

good morning:
you could also send me the manual?

thx

Damaged screens cooler!
filter dirty water

sat con 99 deg f
oil 102 deg f DT= 3°F

sat con 105 deg f
oil 100 deg f DT= 5°F
the adjustment of the oil temperature difference is 4 ° C

it's just a bracket that freezes the left side

I have a problem with a freezer:

the slider will freeze and not open the door, the freezer is a sub-zero

http://cgproducts.johnsoncontrols.com/default.aspx?main.aspx&2

and you check the calibration of the temperature sensor?

Input 110 ° f?

dirty condenser, oil temperature sensor or temperature sensor saturated condenser damaged

thanks dallas duster

yes! T755L carrier sold me the driver instead of the original control step

good morning:

I will replace a step 30hs control of a carrier machine, T775L driver for my question is?

someone changed the contol step for this driver?

I require electrical diagram and...

if possible change celcius to farenheit

that model machine?

Cooler Flow/Interlock
Contacts Opened
During Normal
Operation

RTAD is European model with CLD or human interface panel, the systems are to R-134A and do not need any software to change sensors.
BUT there CGAD model THIS IS FOR LATIN AMERICA

actually consider are temperature sensors that are damaged.

check the pressure with manometers is correct

Might I send that information to my email

High-pressure switch open,
faulty auxiliary contacts, loss
of condenser air, liquid
valve closed, filter drier
plugged, non-condensables,
operation beyond capability.

(s/n EKP0080).....?

machine european?

you could expand your question?

that is what you require?

machine model?

there is really no other option, replace the compressor

381361

readings of the machine will have in operation?

aproach which is the condenser?

need to change the compressor!

you may need the pipe vibration that damages economizer and economizer.

you changed the muffler the economizer line to the compressor?
