E-Tech Case Studies
For over 30 years, we've been saving our customers money and have helped them reduce their carbon footprint as well. These are just a few of the many companies benefiting from our heat recovery systems.
A MAJOR FOOD MANUFACTURER
Product:
Application:
- Circular Econopak designed and manufactured for natural gas-fired 400 hp fire-tube steam boiler.
Analysis:
- Stack gas temperature lowered from 480° F to 315° F at full-fire conditions
- Water temp in Economizer increased from 227°F to 275°F
- 165°F differential translates to fuel savings of 674,123 Btu/hr at full fire
- 4% increase in boiler efficiency
