When it comes to domestic refrigeration, few names carry as much weight as Secop. Formerly known under the Danfoss brand, these Slovakian-made powerhouses have become the backbone of reliable household cooling. Today, we’re breaking down the TLES6FT.3, a Low Back Pressure (LBP) compressor designed for efficiency and long-term durability in R134a systems.
If you’re a technician in the field, you know that the TLES series is prized for its compact footprint and low noise levels. It’s a “set it and forget it” component that handles the rigorous demands of modern energy standards without breaking a sweat.

Efficiency Metrics (COP) & Performance Curve
Efficiency is where the TLES6FT.3 truly shines. The Coefficient of Performance (COP) varies based on the evaporating temperature. Use this table for precise diagnostics during system charging.
| Evaporating Temp (°C) | Cooling Capacity (Watts) | Power Consumption (Watts) | COP (W/W) |
| -35 | 82 | 88 | 0.93 |
| -30 | 110 | 102 | 1.08 |
| -23.3 (Standard) | 149 | 122 | 1.22 |
| -20 | 172 | 134 | 1.28 |
| -15 | 215 | 150 | 1.43 |
| -10 | 268 | 168 | 1.60 |
Wiring & Connection Schematic
For the electrics, the TLES6FT.3 utilizes a standard triangular pin configuration. Proper wiring is essential to prevent winding burnout.
- Common (C): Top Pin.
- Run (R): Bottom Right Pin.
- Start (S): Bottom Left Pin.
- Logic: The PTC starter bridges the Start and Run windings briefly to initiate rotation. If using a CSIR setup, a start capacitor (usually 60-80 µF) is placed in series with the start winding.

Expert Insight: Installation & Maintenance Notice
As a field engineer, I’ve seen these units last 15+ years when installed correctly. The TLES6FT.3 is a “high-tolerance” unit, but it is sensitive to moisture. Because it uses POE oil, which is highly hygroscopic (absorbs water), you must keep the system sealed until the very moment of brazing.
- Pro-Tip: Always replace the filter drier when swapping this compressor. A 15g or 20g drier is standard for this capacity.
- Vacuuming: Do not skip the vacuum stage. A minimum of 250 microns is recommended to ensure the POE oil remains stable.
- Charging: Charge by weight according to the refrigerator manufacturer’s label. Overcharging R134a systems will lead to high head pressure and premature valve failure.
