ATF250D22UMT — ATF250D22UMT is marketed in the 4 HP / 3 TR capacity class. Those labels are useful identifiers, but final selection must use capacity at the actual evaporating and condensing conditions.
ATF250D22UMT quick technical profile
| Model | ATF250D22UMT |
|---|---|
| Nominal listing | 4 HP / 3 TR class |
| Application | Refrigeration and air conditioning |
| Selection basis | Performance at design conditions |
| Commercial mode | B2B quotation; no public price |
Figures in this table are identification and selection references. Cooling capacity, input power and current change with refrigerant, evaporating temperature, condensing temperature, superheat, subcooling and frequency. Use the applicable manufacturer performance data for final design.
Where this compressor fits
The model may be considered for systems in the same nominal capacity class, including packaged cooling and refrigeration equipment. A tonnage label alone does not establish interchangeability because refrigerant, frequency and rating conditions change real capacity.
For a like-for-like service replacement, compare the full original code rather than the base model alone. Suffixes can identify electrical, oil, connection or production variations that are not interchangeable.
Critical checks before ordering
Request the exact performance table and confirm refrigerant, voltage, frequency, compressor technology, connection sizes and oil. Do not convert 3 TR directly into a guaranteed field capacity without the published test conditions.
- Identity: provide a readable compressor nameplate and the complete equipment model.
- Refrigerant: confirm the existing circuit refrigerant and approved oil.
- Electrical: verify voltage, phase, frequency, control method and protection.
- Performance: compare capacity at the real design conditions, not only HP, TR or BTU labels.
- Mechanical fit: check mounting centres, shell height, pipe sizes, orientation and terminals.
Replacement workflow for contractors
Diagnose the original failure before removing the compressor. Check condenser and evaporator airflow, refrigerant charge, oil return, controls, contactors or inverter output, and signs of liquid floodback or overheating. A new compressor will not survive an unresolved system fault.
Recover refrigerant correctly, keep the circuit clean and dry, replace the filter-drier where required, and flow dry nitrogen while brazing. Pressure-test with the approved gas and pressure, evacuate with a calibrated micron gauge, then charge according to the equipment documentation. Commissioning records should include voltage, current, pressures, superheat, subcooling and discharge temperature.
What to send with a quotation request
- compressor and equipment nameplate photographs;
- refrigerant, voltage, phase and frequency;
- required quantity and destination country;
- photos of terminals, pipe connections and mounting feet;
- whether the order is an urgent replacement, project requirement or distributor stock.

Frequently asked questions
Is ATF250D22UMT a universal replacement?
No. Match the full code, refrigerant, electrical design, performance envelope and mechanical connections.
Why is there no public price?
RT Compressor uses B2B quotations because quantity, destination, packaging and technical confirmation affect the offer.
Can I select it by horsepower or tonnage alone?
No. Those labels do not describe capacity across the full operating envelope.
What is the fastest way to confirm availability?
Send the original nameplate, equipment model, quantity and delivery country with the enquiry.
