  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 ...

  A Breath of Fresh, Cool Air: Cambridge ESC vs. Swamp Coolers

  Swamp coolers (evaporative coolers) and Cambridge Air Solutions ESC units both play a significant role in cooling indoor environments, but they differ in their principles of operation and the benefits they offer. While both aim to provide comfort, the Cambridge Air Solutions ESC unit goes the extra mile in enriching lives through its innovative approach to cooling. Now, let's get into what sets them apart... Swamp Cooler (Evaporative Cooler):  Principle of Operation: Swamp coolers work by evaporating water to cool the air. They are highly effective in dry, arid climates with low humidity.  Cooling Mechanism: These coolers add moisture to the air, which helps lower the temperature. The cooling effect is achieved through the evaporation process.  Energy Efficiency: Swamp coolers are energy-efficient and use less electricity compared to traditional air conditioners.  Suitable Climate: They are most effective in hot, dry climates with low humidity levels, as the cooling effectiveness decreases as humidity levels rise.  Cambridge Air Solutions ESC Unit:  Principle of Operation: The Cambridge Air Solutions ESC unit uses an indirect evaporative heat exchanger, wherein cooling is achieved through the evaporative process without adding moisture to ...

  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 ...

  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 ...

  Cambridge Information Bulletin - Selection, Placement & Installation of an S-Series Unit - Thru Wall Mounting

  THRU WALL UNITS  Thru wall units are an excellent choice for many warehouse applications. They do not require any floor space. Typically, the units are mounted in shipping/receiving areas to address the cold air gain at the dock doors.  For manufacturing areas, due to the presence of overhead cranes, thru wall units are frequently not a viable option. The clearance required for an overhead crane at the side wall typically does not allow adequate room to install a thru wall unit.  The heater may have an external gas train. The gas train should be positioned such that the equivalent distance from the outlet of the gas train to the inlet of the heater does not exceed 4 feet. Usually the best location is to place the gas train perpendicular to the side of the heater, so it can be piped directly into the heater’s gas inlet, as illustrated in the S-Series Technical Manual.  Servicing the unit is another potential problem if overhead cranes are present. Accessing the unit via a boom lift or scissors lift will entail entering crane space. This usually means ...
