Monginis Achieves ₹60L Annual Savings with Pune Gas

Executive Summary

Monginis, one of India’s most recognised bakery brands, was facing production delays, quality inconsistencies, and workplace safety concerns at its central manufacturing facility in Bhiwandi due to reliance on Light Diesel Oil for firing industrial baking ovens.

Pune Gas partnered with Monginis to replace diesel with a precision engineered LPG system. The transition delivered faster baking cycles, improved product quality, a safer working environment, and a payback period of approximately eight months, without any expansion in production infrastructure.

Before (Light Diesel Oil)

Monthly
  • Fuel consumption: 2,500 litres per day
  • Daily fuel cost: ₹1,36,000
  • Slower baking cycles and inconsistent heat distribution
  • High maintenance due to soot and carbon deposition
  • Workplace safety and hygiene concern due to emissions

After (LPG System by Pune Gas)

Monthly
  • Fuel consumption: 1,800 kg per day
  • Daily fuel cost: ₹99,000 (↓ significant daily savings)
  • Baking time reduced by 4 minutes per batch
  • Faster production cycles with consistent heat control
  • Clean combustion with no soot or fuel odour
  • Payback period: 239 days (~8 months)

Client Overview

Monginis began as a small bakery in Mumbai and has grown into a franchise-driven network of over 900 outlets across India and Egypt.

The Bhiwandi manufacturing facility produces cakes, pastries, cupcakes, rusks, biscuits, and kharis, supplying over 300 outlets across Maharashtra and Gujarat. At this scale, production efficiency, consistency, and reliability are critical to business success.

The Challenge

At the Bhiwandi facility, diesel-fired ovens created multiple operational and quality constraints:

  • Workplace safety and hygiene concern due to emissions and fuel odour 
  • Slow heat-up times resulting in longer baking cycles 
  • Inconsistent product quality due to uneven heating 
  • High maintenance requirements due to soot and carbon buildup 

The existing system limited operational efficiency and scalability.

The Solution

Pune Gas designed and executed a precision engineered LPG system tailored for high-load industrial baking operations.

The solution delivered:

  • High-capacity LPG system for continuous baking loads 
  • Rapid response burners enabling faster temperature ramp-up 
  • Precise flame modulation for consistent baking results 
  • Clean combustion eliminating soot and fuel odour 
  • Integrated safety and monitoring systems 

System Configuration Highlights

  • 6+6 Hippo cylinder bank 
  • 300 kg/hr vaporizers 
  • 18 modulating burners 
  • Integrated safety and monitoring systems 
  • Total project investment: ₹86 Lakhs

Measured Savings and Operational Gains

  • Faster Production Cycles
    4 minutes saved per batch | ~16 minutes per hour | 3+ hours saved per shift

  • Increased Output
    Equivalent to one additional week of production per month without infrastructure expansion

  • Product Quality Improvement
    Uniform baking with no carbon deposits or fuel odour

  • Maintenance Reduction
    No soot formation, reduced servicing requirements, and elimination of cleaning downtime

  • Workplace Safety Enhancement
    Lower emissions, cleaner air, and safer working conditions

Financial Outcome

  • Significant reduction in daily fuel costs 
  • Strong operational savings contributing to rapid ROI 
  • Payback period: 239 days (~8 months)

Execution

The project was executed with precise engineering and seamless coordination, ensuring installation and commissioning without disrupting ongoing production.

Conclusion

By implementing a precision engineered LPG system, Monginis transformed its industrial baking operations with faster production, improved product quality, reduced maintenance, and enhanced workplace safety. The project demonstrates how fuel transition can unlock efficiency, scalability, and strong financial returns without additional infrastructure investment.
