One-year payback time on supermarket shell-and-tube investment

By installing Alfa Laval CDEW desuperheaters in central cooling systems for stores and distribution centres, supermarket chains can reduce heat waste and make considerable energy savings. One Spanish supermarket recouped its investment in under a year.

DATE 2022-02-03

One major Spanish supermarket chain is ordering 150 S&T desuperheaters per year through the central cooling system builder Zanotti Smart Solutions.

The supermarket uses Alfa Laval CDEW desuperheaters in the central cooling systems of its stores and distribution centres, recovering the heat generated to heat tap water, and to provide radiant floor heating and comfort heating. By doing so, it has reduced its energy costs and its carbon footprint - and its investment has paid for itself in less than a year.

Atencia at the system-builder Zanotti Smart Solutions, is more than happy with the solution. "It is a robust, reliable and easy-to-use shell-and-tube product." Today 80% of Zanotti's installations feature heat recovery systems.
