Major HVAC / Process Cooling Project

Industrial Waste Heat Recovery & Adsorption Chiller Evaluation

Supporting industrial clients with energy-efficient cooling solutions by evaluating the use of production waste heat for chilled water generation.

Project Overview

Turning Industrial Waste Heat into Useful Cooling Energy

This project focuses on the evaluation of adsorption chiller technology for process cooling applications in industrial facilities. Adsorption chillers are designed to use low-temperature waste heat from production processes to generate chilled water for process cooling or air-conditioning.

The generated chilled water can be integrated into the existing chilled water network, thereby reducing the operating hours of conventional compression chillers and improving overall energy efficiency.

Sostanza’s role is to support the technical evaluation, data gathering, system integration review, and project development process required to determine the suitability and savings potential of the technology.
