The Cambridge S-Series: A Lifecycle Cost Comparison

1 MIN READ

When deciding on a system to heat your facility, cost plays an important role. While some project bids might gravitate to the cheapest available option to meet the specs, it is pertinent to consider the other cost factors involved (energy savings and maintenance costs) as they will play a major role in the overall unit life cycle cost.

On our S-Series HTHV heating unit, the unique blow-thru design, with 160-degree maximum temperature rise and discharge temperature, delivers more usable heat and thermal comfort with minimal temperature variation throughout the heated space. In addition, this commercial/industrial space heater is 20-70% more energy-efficient than all other types of indirect and direct gas-fired systems used to heat large commercial and industrial buildings.

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 ...
The True Cost of Doing Nothing When You Are A Facility Manager

This blog was guest written by a Regional Sales Manager at Cambridge Air Solutions. What it Means to "Do Nothing" as a Leader I’m supposing a few of you are picturing your toes in the sand, a good book, the feel of a gentle breeze and the rush of the tide crashing on the sand. Maybe a comfy couch, a Saturday afternoon nap with absolutely nothing on your agenda. Sounds good, doesn’t it? In the facilities management world, doing nothing can take on a different meaning. “Doing nothing” means meeting status quo - nothing more - and it can have a dramatic effect on everything from comfortable workspaces to employee health to retaining the best talent available for the job. When faced with the decision to invest in your facility, it can be tempting to put it off or assume that your current system is performing “OK” and there is no immediate need for action. But now that facility leaders are challenged with creating better cultures and healthier working environments inside their production spaces, the cost of doing nothing is now greater than ever in regards ...
How Does an Indirect Evaporative Cooling Unit Work? | Cambridge ESC-Series Cooling Animation

Employee safety, comfort, and productivity are very important in today’s workplace. Industrial environments with exhaust are one of the more difficult cooling applications. Internal and/or external heat gain can result in excessive temperatures in your building. The exhaust fans located in these types of buildings can make cooling with traditional methods very difficult and expensive. A two-stage evaporative cooling unit can provide cheaper industrial cooling, making your work environments safer, more productive, and more comfortable. The evaporative cooling unit uses 100% outside air to provide tempered make-up air and building cooling. The ESC-Series unit is designed for industrial, commercial, and institutional buildings needing better indoor air quality without the equipment or operating costs associated with mechanical cooling. Cool, tempered air enters your industrial building or warehouse from the two-stage unit. The exhaust fans that are opposite of the indirect evaporative cooling units create a push-pull effect that allows the cooler air to move across your workspace. An indirect evaporative cooling module provides the first stage of cooling. A patented polymer heat exchanger separates the ventilation airstream from the vaporizer airstream, resulting in ...
