The rising costs of energy and construction materials led a manufacturer of non-woven glass fibre veil to consult Operational to evaluate the viability of heat recovery from their production line. Previous attempts to recover energy had failed due to fouling of the heat exchanger heat transfer surfaces and blockage of the air channels.

Operational investigated the various processes and developed a bespoke solution that matched the energy supply and demand in their production processes. Fouling issues were addressed by the incorporation of an innovative in-situ cleaning system. Advanced PLC controls, providing user-friendly interfaces, optimised the amount of heat recovered and re-utilised.

Our client’s production director commented: “Our financial director recognised the moment that Operational’s heat recovery system went live. There was a significant instant reduction in our gas bill.”

Energy Recovery and re-utilisation of 800 kWh was achieved, with cost savings of €220,000 per annum giving a return on investment of less than 12 months.
