KVB Parabolic Trough for Leather Industry

High fuel cost in leather & footwear manufacturing

Leather processing and footwear manufacturing are thermally demanding value-added processes where heat and steam are essential for quality, productivity and compliance. Thermal energy costs are one of the biggest controllable operating expenses for leather plants.

Most leather plants rely on:

  • LPG / Diesel / Furnace Oil boilers
  • Coal / Biomass fired boilers (in some facilities)
  • Electric steam systems (high OPEX)

Business Impact

  • High operating cost
  • Exposure to fuel price volatility
  • Environmental impact & emissions
  • Compliance challenges

Managing thermal energy sustainably has become a competitive necessity.

What if you could permanently reduce a significant portion of your boiler fuel costs?

How the system works

System Process

  • Sunlight hits solar mirrors
  • Mirrors focus energy onto receiver tubes
  • Heat transfer fluid (HTF) absorbs heat
  • Thermal energy generates steam
  • Steam supplied to leather process lines
  • Boiler backup supports during low solar periods

Integration Options

  • Boiler Feedwater Pre-Heat
  • Direct Steam Generation
  • Hybrid Solar + Boiler Backup
  • Thermal Storage (optional)

Industrial Performance

  • Temperature Range: 120°C – 250°C
  • Efficiency: 50–70%
  • Solar Contribution: 20–60%
  • System Life: 20–30 years

Optional thermal storage enables heat availability beyond sunlight hours.

Across leather & footwear processes

Perfectly suited for all major leather manufacturing heat stages

Soaking & Degreasing

80–100°C hot water supply

Liming, Deliming & Bating

90–120°C for chemical processing

Tanning & Neutralization

110–160°C consistent heat

Drying & Conditioning

120–180°C efficient moisture removal

Drum Heating & Finishing

Continuous thermal supply to drums

Boiler Feedwater Pre-Heating

40–120°C — improves overall efficiency

High heat demand across all stages = high solar savings potential

What leather plants gain

  • Reduced Fuel Cost — Replaces a portion of boiler fuel consumption; lower cost per unit of production
  • Stable Energy Cost — Less exposure to fluctuating fuel prices; predictable long-term energy expenditure
  • Reduced Carbon Emissions — Supports environmental compliance and ESG goals
  • Lower Boiler Load — Reduces wear and maintenance on boiler systems
  • Improved Sustainability Credentials — Important for global buyers and export markets

Lower cost + sustainable manufacturing = stronger global competitiveness
