St. Paul’s TowersBurner Retrofit
Burner retrofit on existing boilers to achieve emission requirements.
St. Paul’s Towers, one location in the Episcopal Senior Community network, is a nonprofit senior living community that provides complete continuing care while encouraging intellectual, physical, and social activities. With beautiful views of Lake Merritt and the East Bay, the 23-story St. Paul’s Towers community offers 215 rooms, 43 skilled nursing beds, and 35 assisted living beds.
But the fragile nature of the residents requires reliable heating and hot water 24 hours a day, 7 days a week. To accommodate this need, St. Paul’s Towers was using two Cleaver-Brooks hot water heating boilers, each with inputs of 6 million BTU per hour. When new state regulations mandated that the boilers be brought into NOx emission compliance of less than 15ppm, St. Paul’s Towers was forced to look for a cost efficient solution to seamlessly upgrade their equipment.

Equity OfficeNew Boiler System
San Jose, CA
Dual boiler installation atop a highrise urban building.
Equity Office owns and manages a portfolio of more than 59 million square feet of office space, with a high percentage of signature properties in leading gateway markets throughout the United States. Many of their properties contain boilers under 5 and 10 million BTUs. These relatively small commercial use boilers were previously not regulated by the air district, but with the new and tougher air quality control standards smaller boiler systems must now meet certain levels of emissions as well as operating and maintenance standards.
R.F. MacDonald Co. was approached by Equity Office regarding several specific building systems that did not meet the BAAQMD requirements. In many cases like this one, the process begins with a detailed site survey to assess the existing equipment, the anticipated needs, the surrounding environment and the options available for each specific site to comply with the current district regulations.

Teva Parenteral MedicinesBoiler Retrofit
Retrofit existing boilers to meet low NOx emissions requirements.
Teva Parenteral Medicines has been operating with a Cleaver Brooks Firetube boiler since its installation in 1989. This unit operates around the clock and is responsible for sterilizing products, producing water used for medications, and all of their HVAC needs. R.F. MacDonald Co. has been responsible for maintaining this boiler through their “Annual
Efficiency Program” (AEP) for the past 20 years allowing for the facility to retrofit versus the more time consuming and costly option of replacing the boiler. When Teva approached R.F. MacDonald Co., the boiler was operating at a 35/40% firing rate and at 50% capacity, while running off of an obsolete CB Hawk Controller. Read more
