Efficiency Metrics (COP) and Performance Data
Efficiency in a compressor is defined by the Coefficient of Performance (COP). For the TLES6FT.3, the relationship between evaporating temperature and energy consumption is crucial for maintaining energy ratings.
| Evaporating Temp (°C) | Cooling Capacity (Watts) | Power Consumption (Watts) | COP (W/W) |
| -35 | 82 | 98 | 0.84 |
| -30 | 112 | 114 | 0.98 |
| -25 | 148 | 131 | 1.13 |
| -23.3 | 156 | 138 | 1.14 |
| -20 | 188 | 150 | 1.25 |
| -15 | 240 | 170 | 1.41 |
| -10 | 295 | 192 | 1.54 |
Note: The COP is calculated using the formula: $COP = \frac{Q_c}{P}$, where $Q_c$ is the cooling capacity and $P$ is the power input.
Application and Capability
This compressor is typically found in medium-sized domestic refrigerators.
- Cooling Capacity in Liters: It can efficiently handle cooling for units between 250 to 350 Liters.
- Cubic Feet: Approximately 8.8 to 12.3 cubic feet.
- Capillary Tube Suggestion: For LBP R134a systems, a capillary of 0.031 inches (0.78 mm) with a length adjusted to the specific cabinet load is standard.
Comparison: Secop TLES6FT.3 vs. Competitors
When looking at the market, the TLES6FT.3 competes directly with brands like Embraco and ACC. While it offers a very stable 6.0 cc displacement, some competitors might vary slightly in their start torque performance.
| Brand | Model | HP | Displacement | Gas |
| Secop | TLES6FT.3 | 1/6 HP | 6.00 cc | R134a |
| Embraco | EMT55HLP | 1/6 HP | 5.19 cc | R134a |
| Jiaxipera | ND1112Y | 1/6 HP | 5.80 cc | R134a |
| ACC/Seko | GVY57AA | 1/6 HP | 5.73 cc | R134a |
Replacement Guide
If you are in the field and cannot find the exact TLES6FT.3, here are the professional-grade alternatives.
5 Direct Replacements (Same Gas: R134a)
- Embraco EMT55HLP: Very common, slightly higher efficiency.
- Danfoss TL5G: The classic predecessor, extremely durable.
- ACC / Cubigel GVY57AA: A direct fit for many European cabinets.
- Jiaxipera ND1112Y: Often used in Bosch and Siemens units.
- Tecumseh THG1358YKS: A robust alternative with similar mounting.
5 Indirect Replacements (Alternative Gas: R600a)
Caution: Gas conversion requires a complete system flush, different oil, and a specific R600a charging procedure.
- Secop TLES6.5KK.3: The natural R600a evolution of this frame.
- Embraco EMX55CLC: High efficiency R600a model.
- Jiaxipera NT1113Y: Standard R600a replacement.
- ACC HXK95AA: Known for very low noise levels.
- Wanbao ATA72XL: Budget-friendly R600a alternative for 1/6 HP range.
Professional Advice & Field Tips
- Oil Management: The TLES6FT.3 uses POE oil. This oil is highly hygroscopic (absorbs moisture quickly). Never leave the compressor open to the atmosphere for more than 15 minutes.
- System Cleanliness: When replacing a burnt-out compressor, always replace the filter drier and perform a nitrogen purge to ensure no acid remains in the lines.
- Starting Device: This model supports both LST (Low Starting Torque) and HST (High Starting Torque). If you are working in an area with unstable voltage, adding a start capacitor (HST kit) can significantly extend the motor’s life.
Troubleshooting the TLES6FT.3
| Problem | Potential Cause | Action |
| Compressor runs but no cold | Gas leak or partial blockage | Check high-side pressure and capillary. |
| Clicking sound (Thermal Protector) | Faulty relay or seized piston | Check LRA and relay resistance. |
| High vibration | Worn internal springs | Ensure the external rubber grommets are intact. |
