Developed at IIT Bombay
3 MT Capacity
Battery-free Thermal Storage
Solar Powered Vegetable Cold Storage
Sustainable farm-gate cooling solutions for off-grid & remote rural clusters
The Challenge
Post-Harvest Loss
Perishables spoil within 5-7 days due to lack of cooling, resulting in massive economic wastage.
Rural Energy Gap
Unreliable grid power in agricultural belts makes traditional cold storage unfeasible.
Price Instability
Farmers are forced into distress sales during gluts; cold storage allows market timing.
The Solution
A robust, off-grid ready cooling system engineered at IIT Bombay. It utilizes Ice-bank Thermal Backup to maintain stable temperatures (2-6°C) throughout the night and during power outages without relying on chemical batteries.
Solar Integrated
Optimized for PV power with optional hybrid grid switching.
Remote Monitoring
IoT-enabled tracking of Temperature and RH via mobile.
Pre-Cooling
High-efficiency forced air removes field heat rapidly.
