What We Do
Sidel Systems proudly manufactures the full line of SRU Series Flue Gas Waste Heat Recovery Units. We help companies and government agencies save money on energy bills while reducing CO2 emissions and creating usable water as a byproduct of operating our equipment. We retrofit to your systems to reduce costs.

Save Money
By significantly increasing the efficiency of natural gas appliances, we help our clients lower their electrical energy consumption and water costs. Money that was literally “going up the chimney” goes back on your bottom line as new-found profit.

Reduce C02 Emissions
By reducing the quantity of flue exhaust released from your chimney, we automatically lower CO2 emissions. This not only helps the environment, but improves the public perception of your company or organization. As the “green revolution” gains momentum throughout the world, our products help you promote your efforts as an authentic, environmentally-friendly organization.

Create New Water
By converting the hot waste exhaust gases into usable water, which is a natural byproduct of our high-efficiency technology, we help further lower your utility bills. Every gallon of water created by a Sidel unit is a gallon you didn’t have to purchase. This benefits water conservation and your bottom line. There are many ways that this water can be used, and we’re delighted to discuss how you can make the most of this new resource.

Condensing flue gas recovery systems have been used around the world for more than 30 years. In most applications, savings of 8% to 18% are realized. This is significant considering the high cost of natural gas. 

The Sidel SRU series waste heat recovery units are built in North America in accordance with ASME (American Society of Mechanical Engineers) codes. Our systems can be installed with any natural gas or LPG fired power burner boiler or heating unit. We retrofit to work with your equipment, saving money and time. 

“The Energy Efficiency Experts”
Our clients have been saving money and helping the environment long before “going green” was trendy. Back in 1978, we specialized in the design and installation of hot water heating systems for the commercial greenhouse industry. Greenhouse structures have a very high heat loss factor, so it’s extremely important to achieve maximum fuel efficiency. Building on our success within that industry we have become true experts in energy efficiency. Today, Sidel Systems products are among the most energy efficient, cost effective flue gas waste heat recovery units in the world. Guaranteed.

Our Founders
Sidel Systems Ltd. was founded in 1978 by Sid Abma and his wife Ellen, who lived in Canada at the time. In 1992 they incorporated in California and their company became Sidel Systems USA Inc.

Sid and Ellen are both intimately involved in the daily operations of the company. Despite the organization’s growth over the years Sid still insists on being the primary contact for his clients. That personal involvement and commitment to unparalleled customer service are key reasons why Sidel Systems has successfully helped hundreds of clients achieve their energy-savings goals, and why Sid offers a 4-point, 100% personal guarantee on all of our units that is unmatched in the industry.

Sid is one of those people who always seems to have a positive attitude and considers each new contact he makes to be a friend he hadn’t met before. Sid’s gift for providing helpful information while putting people at ease helps make Sidel Systems one of the most respected companies in our industry. The word “pressure” is not in Sid’s vocabulary. He is a strong servant-leader who brings out the best in others. His goal, as always, is to leave clients, associates and business prospects happy to know him. 

Our company purchased a Sidel SRU 400-80 condensing economizer from Marspec in 2010. Today it operates on an 80,000 pound/hr boiler, but was sized to also handle the exhaust flow of a second boiler of 40,000 lb/hr in the future.

The economizer has run without requiring any maintenance, and has worked effectively in the time since it was installed. I was really surprised when I saw how much condensate was being produced, and the savings in natural gas costs have been substantial. 

Our Condensing Economizer includes a Sidel Therm & CO2 Counter that confirms how much energy is being recovered, and how much CO2 my company is not putting into the atmosphere. Investing in this money-saving technology has been good for the environment and good for our bottom line, and thanks to the folks at Sidel Systems we've had a fantastic experience as well
