-40°C Cooling from waste heat
Ammonia Absorption Chiller – Ago Congelo | Sustainable Cooling from Waste Heat
In an era of rising energy costs and environmental concerns, the “Ago Congelo” ammonia absorption chiller from Vamtec offers a game-changing solution for industrial and agricultural cooling. This advanced ammonia/water absorption chiller delivers ultra-low cooling down to -40°C, leveraging waste heat from industrial processes, combined heat and power (CHP) plants, or gas turbines. Unlike traditional reciprocating compression chillers, which guzzle electricity, the Ago Congelo prioritizes sustainability and efficiency, slashing operational costs while reducing carbon emissions.
Why Ammonia Absorption Chillers Are the Future
Economic conditions have shifted dramatically, with electricity tariffs soaring and heat from decentralized power generation becoming more accessible. This makes ammonia absorption chillers a cost-effective alternative to conventional systems. By utilizing waste heat—often an untapped byproduct—the Ago Congelo transforms inefficiency into opportunity, delivering sustainable cooling solutions for industries like food processing, pharmaceuticals, and data centers. Its minimal electricity demand not only cuts energy bills but also aligns with global decarbonization goals, making it a top choice for eco-conscious businesses.
How the Ago Congelo Works
The Ago Congelo harnesses the ammonia/water absorption cycle for efficient, low-energy cooling. Waste heat from sources like CHP plants or industrial exhaust drives the process, separating ammonia from water in a generator. The ammonia vapor condenses, then evaporates at low pressure in the evaporator, absorbing heat to achieve coolant temperatures as low as -40°C. A small circulation pump—its only electrical component—reabsorbs the ammonia, completing the cycle. This innovative design ensures robust performance in extreme conditions, offering reliable waste heat refrigeration with minimal grid dependency.
Key Benefits of the Ago Congelo
- Ultra-Low Cooling: Reaches -40°C, perfect for specialized industrial cooling needs.
- Waste Heat Utilization: Converts excess heat from CHP plants or processes into valuable refrigeration.
- Energy Efficiency: Minimal electricity use reduces costs and environmental impact.
- Eco-Friendly Design: Ammonia, a natural refrigerant, boasts zero global warming potential (GWP).
These features make the Ago Congelo ideal for applications requiring sustainable refrigeration, such as cold storage, chemical manufacturing, and agricultural cold chains.
Industries Transforming with Sustainable Cooling
The Ago Congelo excels across diverse sectors. In agriculture, it preserves perishables at ultra-low temperatures without straining electrical grids. For data centers, it offers energy-efficient cooling by repurposing server-generated heat, ensuring peak performance while cutting costs. Chemical plants benefit from its ability to handle high ambient temperatures, delivering consistent low-energy cooling. This versatility positions ammonia absorption chillers as a cornerstone of modern industrial cooling systems.
