Textile mills and food processing plants generate massive amounts of hot water—then 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
- 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.
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.
- 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.
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.
