Previously whenever temperatures below zero was required for product cooling in the food industry, electrical compressor or electrical chillers were requested for. However, over the years this has undergone a change with the price of electricity increasing and consequential release of undesired pollutants into the environment.
Therefore, the utilization of another type of energy seems to be a suitable alternative, in particular as it is already available in many companies. Here we are talking about waste heat, which is generated during the production process of food or in a co-generation unit. Often this heat is more or less discharged into the environment without further use. What a waste!
Increasing energy costs prompt companies to look for alternative energy utilization methods. The food industry is no exception.
At Thermax, we offer a glycol-free vapour absorption system that produces chilled water at 1° C for the food industry utilizing this waste heat. Glycol, though moderately toxic, is an anti-freeze agent commonly used in chilled water air conditioning because it cools below the freezing temperature of water. By eliminating it, Thermax helps the customer avoid hazardous leakage, corrosion and the recurring cost of replacing the costly solution.
The 1°C chiller achieves glycol-free operation by enhancing the design of the heat exchanger. The changed tube metallurgy safeguards against freeze failures. Design modifications ensure uniform flow of clean and chilled water.
Customers gain from lower maintenance costs and higher operational savings. In India, several food industry customers have gone in for this chiller – Heritage Foods (Hyderabad), Umang Dairies (Delhi), Sunfresh Agro, Prabhat dairy (Ahmednagar) among others.
