TTC Oil Free Water Lubricated Screw Compressor
The TTC series uses purified water instead of lubricating oil, so the compressed air is clean and free of oil.
What This Machine Does
The TTC series uses purified water instead of lubricating oil, so the compressed air is clean and free of oil. Water seals, cools and lubricates the element and also washes dust out of the air. With no oil separator or oil filter to buy and service, the operating cost is low.
Key Benefits
- Compressed air is free of oil because there is no oil anywhere in the machine
- Air discharge per unit horsepower is 15 percent higher than an ordinary dry type compressor
- No gas oil separator or oil filter to purchase, service or dispose of
- Water also washes dust out of the air during compression
- Ten frame sizes from 7.5 kW to 45 kW at 0.8 MPa
Problems It Solves
- Oil carry over contaminating food product at the ejectors
- Recurring cost of oil, filters, separators and disposal
- Air quality questions during a customer or regulatory audit
- High running cost per cubic metre of compressed air
Who It Is For
- Rice and grain plants running sorters
- Food and pharmaceutical manufacturers
- Packing operations with food contact air
- Plants under audit on air quality
Application Scenarios
- Air supply for optical sorters in food plants
- Food and pharmaceutical processes where oil carry over is unacceptable
- Packing lines handling food products
- Plants replacing an oil lubricated machine on a food contact line
Technical Features
- Purified water used for sealing, cooling and lubrication
- No oil anywhere in the machine, so no separator or oil filter is required
- Noise from 58 dB(A) to 68 dB(A) depending on frame size
- Cooling water quantity and pipe diameters published per model
- Capacity from 1.15 m3/min to 7.3 m3/min at 0.8 MPa
TTC Oil Free Water Lubricated Screw Compressor Model Table
Figures below are taken from the TITAN model sheets. Where a figure depends on the crop or the contamination level it is stated that way rather than averaged.
| Model | Pressure (MPa) | Capacity (m3/min) | Power (kW) | Noise dB(A) | Weight (kg) |
|---|---|---|---|---|---|
| TTC08 | 0.8 | 1.15 | 7.5 | 58 | 500 |
| TTC11 | 0.8 | 1.55 | 11 | 58 | 540 |
| TTC15 | 0.8 | 2.4 | 15 | 63 | 650 |
| TTC18 | 0.8 | 3.1 | 18.5 | 65 | 840 |
| TTC22 | 0.8 | 3.5 | 22 | 65 | 870 |
| TTC30 | 0.8 | 5 | 30 | 66 | 960 |
| TTC37 | 0.8 | 6.1 | 37 | 67 | 1000 |
| TTC45 | 0.8 | 7.3 | 45 | 68 | 1060 |
Cooling water quantity runs from 2 t/h on the TTC08 upward, with inlet and outlet pipe diameters from 3/4 inch to 1 1/2 inch listed per model.

How It Compares With The Alternatives
| Oil lubricated screw compressor | No oil in the air stream and no separator or oil filter cost, which matters on food contact lines. |
|---|---|
| Ordinary dry type oil free compressor | Air discharge per unit horsepower is 15 percent higher. |
TTC Oil Free Water Lubricated Screw Compressor Questions
How does a water lubricated compressor work?
Purified water performs sealing, cooling and lubrication in place of oil, and it washes dust out of the air at the same time.
What sizes are available?
From TTC08 at 1.15 m3/min and 7.5 kW up to TTC45 at 7.3 m3/min and 45 kW, all at 0.8 MPa.
How noisy is it?
From 58 dB(A) on the smallest frames to 68 dB(A) on the TTC45.
What does it save on maintenance?
There is no gas oil separator and no oil filter, and no used oil to dispose of.
How much cooling water does it need?
Quantities are published per model, starting at 2 t/h on the TTC08, with pipe diameters from 3/4 inch.
Is it suitable for food processing?
Yes. Oil free air is the reason plants choose it for food and pharmaceutical lines.
