If you’re looking for a reliable, energy-efficient way to generate compressed air in the 55 kW-to-132 kW range, the TL55-132 two-stage oil-injection screw compressor is worth a close look. Its compact design, robust construction, and intelligent control options make it a strong candidate for everything from small-shop production lines to medium-size manufacturing plants.
Below we break down the key variants (55 kW, 75 kW, 90 kW, 110 kW, 132 kW), compare their performance figures, and answer the most common questions that arise when selecting a screw compressor.
| Model | Rated Power (kW) | Volume Flow (FAD) m³/min | Discharge Pressure (bar) | Cooling | Frequency Conversion |
|---|---|---|---|---|---|
| TL55 | 55 | 8.05 – 10.2 | 6 – 9 | Air / Water | Optional VFD |
| TL75 | 75 | 10.2 – 13.5 | 6 – 10 | Air / Water | Optional VFD |
| TL90 | 90 | 13.5 – 16.8 | 7 – 11 | Air / Water | Optional VFD |
| TL110 | 110 | 16.8 – 22.5 | 8 – 12 | Air / Water | Optional VFD |
| TL132 | 132 | 22.5 – 30.06 | 9 – 13 | Air / Water | Optional VFD |
FAD = Free Air Delivery at rated conditions (20 °C, 1 bar suction). All models feature a dual-stage oil-injection system that guarantees high efficiency (up to 93 % isentropic) while keeping oil carry-over well below 10 mg/m³.
A two-stage design splits the compression process into a low-pressure stage (pre-compression) and a high-pressure stage (final boost). This yields:
| Cooling Type | Typical Application | Advantages |
|---|---|---|
| Air-cooled | Outdoor or well-ventilated indoor installations, where water supply is limited. | Simple, low-maintenance, no risk of leaks. |
| Water-cooled | High-ambient-temperature plants, or where space is tight and a compact heat-exchanger is desired. | Superior heat-removal, lower motor surface temperature → higher continuous duty. |
Both options are factory-fitted and can be swapped during a service visit, giving you flexibility as your plant layout evolves.
The TL55-132 series can be equipped with a Variable Frequency Drive (VFD) that:
If your plant runs at a relatively constant load, a standard fixed-frequency motor may suffice. For fluctuating demand, the VFD is a cost-effective upgrade.
| Requirement | Best Fit | Reason |
|---|---|---|
| Compact shop floor, ≤ 10 m³/min | TL55 | Smallest footprint, adequate flow for light-duty tools. |
| Medium-size assembly line, 12-16 m³/min | TL75 or TL90 | Good balance of power and efficiency; VFD optional for variable demand. |
| High-throughput manufacturing, 20-30 m³/min | TL110 or TL132 | Highest flow and pressure; water-cooling recommended for heat-intensive environments. |
| Maximum energy savings | Any model with VFD | Energy consumption drops dramatically at part-load. |
| Limited water supply | Air-cooled variant of any model | No need for a cooling-water circuit. |
The TL55-132 two-stage oil-injection screw compressor delivers a versatile power envelope (55-132 kW) while maintaining high efficiency, low oil carry-over, and flexible cooling options. Pair it with a VFD for the best energy savings, and you have a robust, future-proof solution for virtually any compressed-air application.
