High Pressure Dyeing Machine

Technical Details 

• Design pressure: 5.2 bar
• Heating gradient: 25-100°C approx. 4.5°C/min 100-130°C approx. 2.5°C/min (dry saturated steam pressure at 7 bar)
• Design temperature: 140°C
• Cooling gradient: 130-100°C approx. 3°C/min 100-80°C approx. 2°C/min (cooling water at 3 bar, 25°C)

  Key Features 

• Multiple safety interlock: distinctive temperature, pressure, and water level multiple safety interlock, ensures operational safety
• Unique fuzzy logic temperature control: temperature control can be confined down to ±0.3°C
• Intelligent leveling control: optimised flow reversal process, optimal inflow and outflow ratio ensuring exceptional leveling result
• Patented all-in-one layout: patented unified compact layout of V-pump, heat exchanger, and 180° flow reversal device. Lower liquor ratio and improved heat exchange efficiency
• Advanced Intelligent Rinsing System (AIR+): fully automated rinsing process optimises rinsing time and water consumption, and gives excellent rinsing quality
• Multi-functional preparation tank: equal-volume multi-functional preparation tank, together with pre-heating and pre-mixing functions, significantly reduces process time
• High temperature drain: allows hot liquor to be discharged without cooling, thus shortens the dyeing time
• Hydro-extraction: effectively removes excess water from packages or beams by pressure difference (assumption single-flow liquor ratio 1:4; dual-flow liquor ratio 1:5.2 on same capacity and recipe)
