Textile mills and food processing plants generate massive amounts of hot waterthen pay premium rates for electric cooling. Hot water absorption chillers solve this by turning 80-95°C waste water into powerful refrigeration.

The Technology Advantage

Operating on low - temperature heat(80 - 95°C), BROAD's hot water VAM chillers unlock waste heat sources that steam chillers cannot use, such as boiler economizers, engine jackets, and process discharge. With a COP of 0.7-0.75, they turn "free" waste heat into valuable cooling.

Why Textile Mills Are Perfect Candidates

Key Drivers:
  • Abundant Waste Heat: Dyeing and finishing consume 200-400m³ of hot water daily.
  • Process Integration: Dyeing discharge (60-70°C) and boiler economizers provide ideal heat sources.
  • Consistent Demand: Mills require year-round cooling for manufacturing floors.

Common Applications:

  • Dyeing Process Cooling: Use waste heat to generate chilled water for fabric cooling baths.
  • Floor Conditioning: Cool worker areas using boiler economizer heat.
🧵 Case Study(Tamil Nadu): 400 TR chiller using dyeing waste heat.
Result: Saved ₹1.2 crores/year.Reduced boiler fuel by 18 %. Payback: 2.1 years.

Food Processing: Turning Heat into Cold

Food plants ironically burn fuel for heating(pasteurization) while buying electricity for cooling(refrigeration).Hot water VAMs bridge this gap.

Key Applications:
  • Pasteurization & Sterilization: Reclaim 85-95°C water after process use.
  • CIP Systems: Utilize hot water from cleaning cycles.
  • Cold Storage: Drive refrigeration for dairy/meat storage using process waste heat.
🥛 Case Study(Maharashtra Dairy): 500 TR VAM using pasteurization heat.
Result: Saved ₹1.65 crores/year.Reduced water use by 35 %.

Technical Integration Strategies

  • Boiler Economizers: Upgrade to feed 85-95°C water to chillers.
  • Cascading Heat: Use hot water for cooling first (90°C→80°C), then for boiler feedwater.
  • Solar Thermal: Augment waste heat with solar collectors for near-zero operational costs.
