With the increase in demand for California wines, process boilers are in great demand. Many of the smaller boilers that were not previously monitored are now required to obtain permits and comply with emission regulations.
St. Helena, CA
Simultaneous heating and condensing is achieved with this unique boiler.
Charles Krug, Napa Valley’s first winery established in 1861, has been owned and operated by the Peter Mondavi family for more than four generations. Charles Krug is recognized as an innovator and pioneer in the winemaking industry, with their exquisite line of critically acclaimed wine vintages being enjoyed by aficionados and casual consumers alike.
To assist the fermentation step in the winemaking process, Charles Krug was utilizing a steam boiler to heat their wine to temperatures below 90°F. Unfortunately, the boiler was an older model and relies on a heat exchanger to produce high pressure steam; an unnecessarily expensive and inefficient technology. On top of that, the steam from the boiler was being routed to several different processes throughout the plant. Looking to improve their production process, Charles Krug consulted with R.F. MacDonald Co. to bring the quality of their wine to its fullest potential. Read more

The Wine Group, FranziaBoiler Retrofit
Retrofit existing boilers to meet low NOx emissions requirements.
Approximately 20,000 tons of fresh grapes are processed annually to produce white and red grape concentrate. One Trane Murray 31,000 PPH Industrial Watertube boiler supplies steam to the juice concentrate plant and process heaters.
The boiler was originally retrofitted in 1999 with a Power Flame low-NOx burner designed to operate at less than 30 ppm. In 2003, the Air Pollution Control District began workshops with the intent to further limit NOx emissions. With this new rule pending, The Wine Group approached R.F. MacDonald Co. requesting a solution that would allow the boiler to operate below the new limits of 9 ppm NOx. Read more

Delicato Family VineyardsBoiler Replacement
Replace existing boiler to meet low NOx emissions requirements.
Delicato Family Vineyards is a family owned winery that owns and operates over 10,000 acres of vineyards, producing a variety of wines for distribution throughout the United States. The company used an Atmospheric boiler on their bottling line in the sterilization and preparation of wine bottles, as well as for some tank heating.
The San Joaquin Valley Air Control District required conversion or replacement of boilers within the district in order to meet Air Pollution Control District Rule 4307, which required emissions to be 30 ppm or less based on the boiler capacity. Since atmospheric Boilers are no longer allowed within the state of California, and there is no conversion package available, the boiler needed to be replaced. Read more
