Join the Movement with GreenCHILL™ Carbon-Neutral Green Refrigeration
Our GreenCHILL™ product is a biomass-powered refrigeration unit, which combines adsorption-based refrigeration with biomass combustion, offering clean cooling facilities to our users. A standalone biomass-powered refrigeration unit of 4 TR; 20 TR output is designed to be integrated with a cold room of 10 MT – 400 MT storage capacity. It uses proprietary adsorption refrigeration technology combined with a biomass combustion unit to provide hot water for driving the adsorption cycle.
We are tirelessly working to strengthen the cold chain infrastructure from farm to table without exerting additional pressure on the current national grid capacity.

Our Portfolio
New Leaf’s patented Biomass-Powered Refrigeration systems combine energy efficiency, carbon neutrality, reliability, easy installation, and superior performance. We specialise in providing two models in our refrigeration unit series: the GC 400 and the GC 2000. Here are the details:
GC 400
Featuring a cooling capacity of 4 TR (14 kW), this unit is ideal for various applications, including cold rooms, ripening chambers, dehydration (add-on) at the farm gate, ice plants, mushroom chambers, hydroponic setups, and more.
The GC 400 is a best fit for a 20 MT single-chamber cold room or a double-chamber cold room with 10 MT capacity each.
GC 400 requires just 6 - 8 kg of biomass per hour and consumes only 0.65 kW of single-phase electricity.
GC 2000
Featuring a cooling capacity of 20 TR (70 kW), this unit is ideal for various applications, including process cooling, milk chilling, ripening chambers, cold storages etc.
The GC 2000 is ideal for cold rooms with capacities of up to 400 MT, offering flexible configurations such as single, dual, or four-chamber setups with precise temperature control.
GC 2000 requires up to 40 kg of biomass per hour and consumes only 3 kW of single-phase electricity.

Unique Features
Refrigeration Unit Specifications
GreenCHILL™ uses an Adsorption Refrigeration Cycle, in which refrigeration is produced by adsorption of the refrigerant. Unlike the vapour compression cycle, no compressor is used. The compressor is replaced by a three-step process achieved by the adsorber, and the desorber. The operation of vapour adsorption cycle is based on the ability of porous solids (the adsorbent) to adsorb vapour (refrigerant) when at low temperature, and to desorb it when heated.
How does it work?
Combustion Process: The combustion in GreenCHILL™ is regulated by a computer system, like Internal Combustion (IC) engines.
Evaporator Temperature can be set by user: -20°C to +20°C
IoT enabled:
The website www.greenchill365.com utilises Internet of Things (IoT) and Microsoft Azure IoT technologies to collect real time data of multiple parameters like temperature, pressure, etc. This is useful in the monitoring of systems, predictive maintenance and transparently calculating the Carbon Credits earned.
Control System: Automatic, computer-controlled. DX evaporators with electronic expansion valves.
Fuel Distribution: The fuel is deposited on a grate, and agitated to ensure even burning. In larger GreenCHILL™ units, the biomass combusts before it reaches the grate, which reduces emissions and enhances energy efficiency.
Installation requirements: Well-ventilated space, protected from rain and direct sunlight.
Humidity Control: Via large evaporator design heat transfer area to minimise condensation to maintain humidity in cold rooms.
Fuel Feed: Fuel is dispensed at specific intervals. The quantity and frequency are determined by the type of fuel and the required cooling power.
Ash Removal: The grate is agitated to eliminate ash. The air supply can be turned off during this process to reduce fly ash production.
Idling State: When the system reaches the pull-down temperature, the fuel supply can be decreased to 2% to maintain heat. This allows the system to restart immediately if the temperature rises.
Temperature Monitoring: The temperatures of the fuel gases are monitored to optimise efficiency.
In 2021, the United Nations Development Organization (UNIDO) & Confederation of Indian Industry (CII) - Sohrabji Godrej Green Business Center, Hyderabad, verified the performance of the technology at Madhur Fruits, by applying the International Performance Measurement and Verification (IPMVP) protocol.
GreenCHILL™ Performance
With GreenCHILL™, users observe a significant reduction in the specific energy consumption (kW/TR) reduced from 2 kW/TR to 0.15 kW/TR, in comparison to a conventional compressor.
GreenCHILL™ vs. Grid Powered Compressor
GreenCHILL™ is a refrigeration unit that uses waste to generate cooling, eliminating the need for grid power or diesel, the energy source for conventional compressors. It's an eco-friendly solution for refrigeration and waste management.
How GreenCHILL™ Effectively Reduces Pollutants
GreenCHILL™ effectively reduces pollutants, with the emissions differing with each biomass type. The combustion in GreenCHILL™ is regulated by a computer system and the following mechanism is adopted:
PM 2.5
The GreenCHILL™ hot water generator is specifically designed for combustion of loose biomass with adequate air to reduce CO emissions below government norms. This is evident from the recent stack emission report. The cyclone filter, coupled with the hot water generator, removes soot, reduces particulate matter, and maintains flue gases as per pollution control norms.
NOx
In the GreenCHILL™ system, the combustion temperatures are maintained below 850°C. This is crucial because Nitrogen Oxides (NOx), harmful pollutants, only form at combustion temperatures above 1200°C, which is common in Internal Combustion (IC) engines.
SO2
Sulphur & Phosphorous reacts with Calcium, forming clinker particles, thus reducing SO2 release in the flue gas to negligible levels.
CO, HC
Eliminates Hydrocarbon (HC) and Carbon Monoxides (CO) pollutants emissions through efficient burning, the use of primary and secondary air, and maintaining 15% excess air. These measures ensure the absence of HC or CO in the flue gas.
C
Through efficient, complete, and slow combustion, the likelihood of carbon in the exhaust is reduced. Any remaining carbon is removed by a cyclone filter in the exhaust system.
VOCs
GreenCHILL™ takes both primary and secondary air from the bottom and sides with excess 15% air, so that Volatile Organic Compounds (VOCs) don't get created out of the GreenCHILL™ process.
Fly Ash
The cyclone filter of GreenCHILL™ removes fly ash.
