Commercial and industrial processes use a large amount of heat energy. During these processes heat energy is extracted and dumped into the atmosphere along with unusable gases.
This energy can be reused to heat auxiliary processes and spaces. The patented SigmHRV system can recover and reuse energy that would otherwise be lost. The heat exchanger is able to perform in harsh commercial and industrial environments such as kitchens and processing plants without clogging.
The systems are bespoke to meet the needs of individual clients.
The SigmaHRV operates on a counter-flow principle i.e. Dirty air is extracted from the process and passed through sealed passages in the heat exchanger. At the same time fresh cold air is also passed through adjacent passages.
The hot air stream gives up heat to the cold air stream. The dirty cooled air is exhausted to atmosphere. The fresh heated air is used in other parts of the process. Both air streams are made to flow counter to each other along a torturous turbulent path without cross contamination.
In this trial the heat exchanger was able to rise outside air temp by 20°C-30°C degrees
