Presentation
The Auto-Chroma IR 323EA is a lab infra-red dyeing machine operating on a "fill it & shut it" principle with automatic chemical dosing. It is suitable for dyeing fabric samples, yarns, fibres and blends and compatible with a wide range of dyes and dyeing methods. The unit is constructed in stainless steel and features a colour touch screen with multiple pre-set dyeing programs.

Essential innovative advantages

• Ease of use
• Colour touch screen control panel
• Save and recall memory system
• Low liquor ratio dyeing capability
• Prevents temperature dips and hot spots across identical sample types
• Reduced dyeing time thanks to automatic dosing of dyestuffs, alkali and auxiliaries
• Dye accuracy via micro‑metric step-by-step dosing without machine stoppage
• Reproducibility ensured by patented round pot design for consistent colour uptake
• Ergonomics: very low noise level
• Durability: stainless steel construction

Main features

• Programmed temperature control for ramp, hold and cooling phases
• Automatic dosing control for auxiliaries and dyestuffs
• Fully automatic chemical dosing and temperature & time control via a specially designed round dye pot with 2 automatic dosing reservoirs and patented click-valve
• Temperature range: ambient to +135°C
• Heating rate: +0.1 to +2°C/min
• Cooling by water heat exchanger and air circulation fan (>500 m³/h)
