BROAD U.S.A. is a privately held company headquartered in New Jersey, supporting the sales and service to our customers in North America. Relying on our innovative and environmental-friendly technology, BROAD U.S.A commits itself to optimize energy efficiency for clients in Commercial, Civil and Industrial markets.
BROAD U.S.A. is committed to the Absorption Marketplace – It is our primary business since we started in 1998
Broad is dedicated and focused on ensuring our owners can always find proper training, service and after sale support with replacement parts and or units.
Broad is committed to the inherent value and flexible solutions that thermally driven absorption plays in our modern world.
We Roll Our Own – Absorbers
Absorption design is our core competency and primary focus
. Unlike many current players in the absorption market, Broad designed and created its first absorber in 1988 with its own human capital, hard work, the desire to be the best.
This homegrown approach has allowed Broad to continue to innovate and lead as the worldwide customer base has grown to over 80 plus counties.
Broad supports CCHP/Co-generation
BROAD has worked closely with the US Department of Energy (DOE) to 
assist in some early US-based demonstration deployments of high-efficiency solutions to co-generation heat recovery.
A prime example of this early cooperation was the demonstration site at Fort Bragg in North Carolina “The 82nd Airborne” back in 2001 BROAD USA is an active member of the USCHP and EPA CHP partnership. Broad is assisting in the August 2012 executive order to deploy over 40GW of CHP by 2020.
Why BROAD Factory Tests Every Chiller as Standard?
Ensures the chiller will yield the operating performance characteristics as designed. It can also be a great opportunity for the operator to learn about the unit which will be cooling or heating the building and to become an expert in the operation of the absorber.
The only way to really validate that the chiller supplied is meeting the design specification requirements. Field testing can be extremely challenging and expensive to replicate. Lowers risk of “system issues” and eliminates field verification of chiller performance which can be very time intensive and difficult to accomplish.
Whole Unit Testing Platform – Our factory acceptance testing (FAT) facility has over 40 test beds for comprehensive performance tests. It is the largest most advanced whole unit testing platform in the world. Broad testing facility has been certified since 1997.
Setting the Bar High on Standards
Broad Absorbers whether they are simple single stage or ultra-high efficiency multi-energy two stage chillers all are designed to the same Stringent Vacuum Standard. The passing test for the Broad standard helium detection test is 10-8 atmospheres of pressure per cubic centimeter of volume per second an industry best in class.
Tube material choice and the impact on the longevity of the absorber coupled with a great design and good vacuum is what a modern absorber is all about. BROAD typically is providing higher quality materials such as “oxygen free copper”, CuNi and thicker walls to ensure the chiller meets it 25-year life design cycle without unplanned and costly re-tubing common in other older absorption designs.

BROAD Tenet
Perfect oneself and be outstanding, restrain oneself and be absolutely obedient
BROAD Moral Line
7 ”Nos” & 1 ”Without”
No environmental pollution, No technology plagiarism No customers cheating, No vicious competition, no chain debts, No tax dodging, no bribery, and Without malicious conscience
BROAD Employee’s Moral Line
10 ”Nos” & 1 ”Without”
Ten (10) ”Nos” & One (1) ”Without” No malfeasance, no indolence, no promise breaking, no lie, no clique, No betray, no bribery, no avarice, no waste, no pollution Without sourness
The core values of BROAD include responsibility to our environment which nurtures us, responsibility to humanity which inspires us, responsibility to our customers who support us, and responsibility to our employees who dedicate their energy and creativity for all of us.
For the environment, everything we do is from the perspective of sustainability: Increasing energy efficiency, reducing energy consumption, reducing energy costs, and reducing consumption of materials.
For humanity, sustainability is wired into the DNA of the full spectrum of BROAD’s diverse product lines: Non-electric chillers, sustainable structural material, clean air machines, prefabricated negative pressure rooms, and many other products. BROAD reduces our customers’ carbon footprint, and charts the way to a future of sustainable cooling and heating, building construction, and air purification.
For our customers, we aim to be an enterprise one is proud to do business with. For many companies, perhaps profit is most valued. At BROAD, our aim is to be distinguished by excellence in products and service: to conceive of and make products no one else can make, and to offer a level of service no one else can provide. So what sort of enterprise does that make us?
In an era of social transformation plagued by vague moral standards
BROAD adheres to the “Principle of 7 Nos and 1 Without”: No environmental pollution, no technology theft, no cheating, no vicious competition, no chain debt, no tax dodging, no bribery, and without malicious conscience. BROAD believes morals are more important than competition, and responsibility is more important than growth.
How are our values reflected in our core product lines?
In our era of global warming, environmental deterioration, and ozone depletion, BROAD continues to innovate and invest in our absorption chiller, now in the 12th generation, to capture waste heat for power and contribute zero ozone depletion, because we believe that environmental protection is more important than profit.
In our era of deteriorating air quality, BROAD has abandoned our ROI model and invested huge sums in air purification systems that provide 100% fresh air with no recycled air, unlike the 70% return air/30% fresh air of most conventional air handlers. In our era of pandemic caused by COVID-19, BROAD has developed a Negative Pressure Isolation (NPI) facility by combining our expertise in prefabricated stainless steel buildings with our air purification prowess to develop a treatment center than can be built in days, and protects medical staff and enables them to treat patients in the safest environment possible. Another innovating product others cannot make, backed by service others cannot provide, because we believe that human health is more important than profit this year or next.
In our era of accelerating urbanization, BROAD has brought for a new structural material made of hardened stainless steel: B-CORE. Tall buildings can now be built without concrete or carbon steel, which together account for over 12% of total global emissions. B-CORE challenges conventional building traditions, providing the more energy efficient, healthiest buildings which have an almost unlimited lifespan as stainless steel is so non-corrosive. BROAD poured huge investments into this technology, because the future of the human race is more important than the future of us an individuals.
Every day, BROAD aims to demonstrate our loyalty to our customers, fairness to our vendors, and dedication to our employees. Long term relationships are more important than gains or losses.
