| Parameter | Typical Values |
|---|---|
| Working Temperature | Up to 140C is common; some machines allow up to ~150C. |
| Working Pressure | Around 45 bar ( ~56kg/cm) for high-pressure dyeing of synthetics. |
| Liquor-to-Material Ratio (MLR) | Very low liquor ratio: often 1:6 to 1:8, sometimes up to 1:61:8 for larger batches. |
| Material of Construction (Wetted Parts) | Stainless steel, especially SS316 / SS316L for corrosion resistance. |
| Heat / Cooling Gradients | Heating gradient about 25C 130C at ~3C/min; cooling from ~130C to ~8085C at slower rates, depending on cooling water pressure. |
| Pump & Circulation | Turbo or reversible turbopumps; InOut & OutIn circulation; variable speed drives/inverters. |
| Capacity / Batch Size | Ranges from small sample machines (few kg: 1520kg) up to hundreds of kg (100500 kg), depending on use. |
| Drain Temperature | Many machines are able to drain liquor at elevated temperatures (e.g. ~130C) to help eliminate unwanted residues, oligomers, etc. |
Front / Top Lid Door with pneumatic or hydraulic locking, with safety interlocks.
Control System: PLC or dyeprogrammer (digital), touch interface; temperature/time controls; sometimes monitoring pH, flow, pressure.
Heat Exchanger internally to reduce heat loss and improve efficiency.
Colour / Chemical Addition Tanks with injection / metered dosing.
Air Pad System (for reducing liquor ratio, better coverage) or flooded system option.
Sample Pots for checking dyeing result while operation ongoing.
Safety & Monitoring: water level sensors, pressure and temperature safety interlocks.
