  Commercial and Industrial Freeze Protection | The Cambridge Spec-Air Series

  Developers working with speculative warehouses and buildings that need ventilation and minimal heat often find themselves producing more heat than is necessary. The Cambridge Spec Air Series is exactly what you need when your goal is not to provide comfortable heating, but to provide the freeze protection and building ventilation required for a new warehouse or speculative building.  The real need is to provide proper airflow with commercial and industrial freeze protection solutions that meet the building code requirements. Spec buildings and warehouses, such as storage facilities or rentable unoccupied spaces, do not need comfortable heating. That’s why our Spec Air Series is designed to provide freeze protection up to 45 degrees Fahrenheit.  Even though there won’t be anybody inside the speculative buildings, it’s important to have proper building or warehouse temperature control to prevent freezing pipes. Keeping your building in the best shape possible is key to finding a tenant to rent the facility. The Spec Air Series Solutions units are roof-mounted and are designed to pull in 100% outside air. No additional duct work is needed since the discharge ...

  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 ...

  Retrofit Case Study: Cambridge HTHV Heaters vs Direct Fired Recirculation

  In Fairmont, WV, a manufacturer with a 160,000 ft2 building faced a challenge. They were using direct-fired-recirculation units to heat their facility, but this resulted in uneven temperatures, high operating costs, cold dock areas, and maintenance headaches. They knew they needed a solution that would not only reduce their energy consumption and carbon emissions but also save on annual operational costs. That's when they decided to turn to the Cambridge S-Series. Choosing the Cambridge S-Series proved to be a game-changer for the manufacturer. The Cambridge system provided more even temperatures, warmer dock areas, lower operating costs, and lowers maintenance costs. Their total operating cost with the Cambridge system was only $0.65/ft2, which is significantly lower than the previous operating cost of $1.12/ft2. What's more, the Cambridge system used less total energy, resulting in a remarkable 42% reduction in carbon emissions, or 410 fewer metric tons of CO2 per year. Thanks to their choice of going with the Cambridge S-Series, the manufacturer can now enjoy annual savings of up to $1.54 million over 20 years. Cambridge units are built to last, with low maintenance ...

  Cambridge S-Series Preventative Maintenance Schedule

  Proper maintenance is essential to keep your Cambridge S-Series heating unit running efficiently and prevent costly repairs. This blog outlines a preventative maintenance schedule for your unit. Depending on whether your unit has filter sections, inspections should be done two or four times a year. In this guide, we'll cover crucial tasks like checking air filters, greasing bearings, inspecting belts, and more. By following these steps, you'll extend the lifespan of your equipment and optimize its performance, reducing energy costs and minimizing downtime. Let's get started on maintaining your Cambridge S-Series unit.  *Full maintenance procedures and instructions may be found in the applicable product tech manual. Suggested inspection Frequency:  2 times per year for units without filter sections  4 times per year for units with filter sections  Check the air filters: Clean these filters if necessary because dirty filters will reduce CFM and could damage the discharge air sensor.  Service the filters as needed based on the “loading” experienced. Clean filters typically start out with a pressure drop across the filters between 0.15 and 0.25” WC. Cleaning or replacement is generally required below the pressure drop increased by ...

  The Right Solution For Industrial Cooling Lies Somewhere Between DX Cooling And HVLS Fans

  Evaporative cooling can provide significant temperature relief at a fraction of the cost of mechanical cooling. Industrial settings - with much exhaust airflow for contaminants and a substantial footprint - can struggle to achieve clean and temperate indoor air conditions without expensive mechanical cooling systems. However, the sheer size of many of these facilities prices that technology out of the possible solution set. On the other end of the cooling option spectrum, HVLS fans tend to move the hot air around, dependent on contact cooling for temperature relief. The moving air from HVLS fans can help employees feel more comfortable but cannot address internal heat gains within a facility nor provide temperature relief. Somewhere between those two options stands evaporative cooling technology, which provides tempered make-up air while also improving indoor air quality with the usage of 100% outdoor air.    Two-Stage Evaporative Cooling Technology Shines in Industrial Facilities The Cambridge ESC-Series evaporative cooling unit is a semi-custom fabricated air handler that can utilize direct (DEC), indirect (IEC) evaporative cooling, or a combination of both indirect/direct (two-stage) evaporative cooling to meet specific usage ...

  Mechanical Contractors and Energy-Efficient HVAC

  What Mechanical Contractors Need to Know about Energy Efficiency and HVAC Building owners rely on your expertise. But it takes trust to make this possible. And to create it, you want to ensure they’re receiving the HVAC solution that makes the most sense for their facility and budget. You already know that top-line price isn’t the most important factor in determining the cost of equipment. And it’s impossible to have conversations about lifecycle cost without talking about energy efficiency. Your customers are going to be invested in reducing their monthly energy bill. Reducing that translates to more business. Heating: Direct-fired High Temperature Heating and Ventilation (HTHV) tech, unit heaters and heat pumps You want to heat big spaces and your customer doesn’t want to pay big bills. How do you do it? For large commercial spaces, direct-fired technology offers a clear pathway to energy efficiency. Without heat loss via a flue, direct-fired heaters achieve 92% thermal efficiency, meaning that 92% of all therms provided to the unit are provided to the building as heat. Indirect-fired heaters make more sense for smaller, enclosed spaces (like your home), due to the lower risk ...
