  Why Hybrid HVAC Systems Are the Smarter Solution

  Hybrid HVAC Systems – Learning from the Auto Industry’s EV Shift This blog was written by The Marketing Team & The Engineering Team The push toward electric vehicles (EVs) sounded revolutionary, but the auto industry’s experience reveals hard truths: massive upfront costs, performance challenges, and an infrastructure not yet ready to support full electrification. Similarly, the HVAC industry is seeing regulatory pressure to adopt all-electric solutions, even though those systems often fall short when performance and reliability matter most—especially in extreme weather or high-demand scenarios. We believe a hybrid HVAC approach offers a smarter way forward, just as hybrid cars combine the benefits of both gas and electric engines. Keeping natural gas as part of the HVAC equation ensures the system can meet both current needs and future demands—without the risks of relying solely on electric power. Key Lessons from the Automotive Shift The journey toward electric vehicles has provided some critical insights HVAC professionals should heed: High Upfront Costs: EVs require significant investment, much like all-electric HVAC systems often demand costly upgrades without matching the efficiency of established alternatives. Performance Gaps: While EVs excel in ...

• Duct Smoke Detector Requirements For Make-Up Air & Heating Units.

  Many building owners working through retrofit or new construction projects are familiar with International Mechanical Code (IMC) standards, which state that an HVAC smoke detector be installed on any air handling system with a capacity greater than 2,000 cubic feet per minute (CFM). Following installation of a new air handling system, most building owners will need to have their new heating or ventilation equipment inspected by municipal code authorities, who adhere to requirements put into place by the IMC. A common item flagged on installations of industrial HVAC equipment—including Cambridge Air Systems products—is that a smoke detector was not installed on the system. This is a common request made by engineers and building inspectors that we see at Cambridge Air Solutions – and is a misinterpretation of how our 100-percent outside air make-up air systems and industrial heating products work. Have you ever received a request to include an HVAC smoke detector with your Cambridge heater? You are not alone. Within this article, the experts at Cambridge seek to alleviate any confusion over whether a smoke detector should be installed ...

  How Two Military Bases are Keeping Fully Operational by Investing in their Facility’s Heating and Ventilation Systems

  Camp Casey and Camp K16 are two U.S. military bases in South Korea that are committed to providing a safe and comfortable environment for the brave men and women who serve our country. But during the deeply cold winters, maintaining a healthy working environment for the troops can be a real challenge.   Recently, an HVAC manufacturing representative local to the base brought Cambridge Air Solutions technical experts to Camp Casey and   Camp K16 to provide training on the S-Series HTHV heating system and M- Series ventilation systems. The S-Series - is designed to maintain set point temperatures with minimal maintenance, tempers 100% outside air for clean, even heating through the large spaces.  The M-Series – designed for its flexibility in bringing make-up air to industrial applications – was ideal for the demanding environment of these military bases. The team provided on-site training at each location, ensuring that they have the knowledge and skills needed to operate the heating systems to ensure the best indoor air quality and thermal comfort for the troops. The leaders at Camp Casey and Camp K16 understand the impact the working conditions can have on the people within the various military facilities and since implementing these cutting-edge heating solutions, they can now maintain even indoor air ...

  Heat Pumps vs. Gas-Fired: 4 Insights for Mechanical Contractors

  Choosing Between Heat Pumps and Gas-Fired Systems: 4 Things Mechanical Contractors Should Consider This blog was written by the Marketing Team and the Applications Engineering Team Choosing the right heating system for your facility is a critical decision for mechanical contractors and their clients. With ongoing conversations around energy efficiency and sustainability, heat pumps are gaining traction as a potential alternative to gas-fired technologies. But making an informed choice means understanding the trade-offs. Here are four key considerations when evaluating heat pumps versus gas-fired systems, plus an introduction to hybrid systems that blend the benefits of both. 1. Upfront Costs: Short-Term vs. Long-Term Investment Heat pumps are often celebrated for their efficiency, but they come with a higher upfront price tag compared to gas-fired systems. Contractors and their clients may find the initial investment daunting, especially when gas-fired options offer a more budget-friendly entry point. However, don’t just look at the sticker price—consider the total life cycle cost of both systems. A heat pump may offer savings over time due to reduced energy usage, but each system should be evaluated based on the ...

  The Path to Net Zero Utilizing HTHV Technology

  *This article was originally published as an advertorial in ASHRAE Journal, July 2022 More and more, leaders want to provide comfortable workspaces for their employees with HVAC that’s both reliable and sustainable. Persistent challenges such as uneven temperatures and inadequate ventilation can be addressed head on with the right equipment and technology. These systems also play a vital role in the reduction of natural gas consumption resulting in lower carbon emissions.  While electrified systems that produce zero carbon are a long-term goal for some, the reality is that leaders will need to make decisions for their facilities long before that goal will be achievable. Finding partners and technology that require less carbon, especially for large, high-bay facilities is instrumental to helping these leaders along that path. Cambridge Air Solutions’ proprietary HTHV technology in our S-Series heaters enables industrial space heaters to be more energy efficient than all other types of indirect and direct gas-fired systems. Since they only require a very low energy use per square foot, facilities can realize a 20-70% reduction in energy usage, according to a DOE study. This energy ...

  The True Impact of Heat on Workforce Productivity

  How Hotter Seasons Impact Workforce Productivity and Cost Building Owners Money This blog was written by The Marketing Team & The Engineering Team As temperatures continue to rise each summer, mechanical contractors may already be aware of the impact that extreme heat can have  on comfort and building operations. But there's another critical element at play—productivity. When indoor temperatures surpass 77°F (25°C), it's not just uncomfortable; it's a hidden productivity killer that directly affects the bottom line of your clients' businesses. Let’s dive into the data to explore the real impact of temperature on productivity and how you can help your customers mitigate these effects. Study Summary: Impact of Heat Exposure on Female Brickfield Workers in India A recent study examined the effects of extreme heat on female workers in India’s brick-manufacturing units. These workers experience high seasonal temperatures for several months of the year, affecting their physical well-being and output. Key findings: Heat Exposure: Workers endure high temperatures for five months annually, with heat from brick kilns worsening the situation. Productivity Decline: For each degree increase beyond 34.9°C, productivity drops by approximately 2%. Physiological Strain: Higher ...
