Any body can help me?
The old TXV has totally under capacity, now I want to replace the new TXV and the problem is to select the new TXV match to the A/C system capacity.
-to select TXV tonnage
-compressor is 25 tons
-A/C system for 1200 sq feet area
what is the make model and serial number of the a/c unit? that can help with getting a new one? what refrigerant? and pipe sizes? all this info will help
in getting the correct txv
Your wholesaler should also be helpful in helping you select the correct one if you provide them with the information. Don't be shy in asking for catalogs. The Internet is also helpful, sporlan has a good site that can help you. As you probably know, selecting the right one is extremely important.
How did you arrive at the conclusion the TXV is too small? In my experience, TXV's are the most wrongly accused parts of a refrigeration system.
25 tons for cooling 1200 sq ft. !!! must have an extreme heat load

Once you go black...you never go back to galvanized.
Actually this TXV problem is for control room at oil and gas platform.
This A/C unit is custom made by manufacturer.
Superfittertech: - sorry for that wrong info Room area (40ft x 50ft)
- Control room
Cool_tech :- the data is
- Compressor type is Carlyle 06ET265660 (semi-hermetic)
- Total capacity is 280789 Btu/hr
- Sensible Capacity is 186931 Btu/hr
- Cooling coil duty = 154 kW
Somethings are not adding up.
So this is a 2000 square foot room?
Compressor is rated at 23 tons
Cooiling coil is 154kW X 3414 (BTU per KW) = 525,756 BTU/h or 43 tons
Do you know how much air you put through the evaporator? Is it 100% outside air or recirculated return air?
