The horsepower paradigm

Watching from the pits of a National Hot Rod Association (NHRA) event, while a team of mechanics ushered a top fuel dragster into their tent, broke the engine down, retooled and quickly rebuilt 6000 horsepower in front of me. These guys know how to harness an extreme amount of power necessary to propel a driver ¼ mile in less than 4 seconds. While I observed the bevy of activity taking place like a well-choreographed production, a team of technicians huddled around a computer display, making minute adjustments to the engine; trying to tweak out every last drop of power necessary to win the next race.

What are these technicians most concerned about? Atmospheric conditions and its direct effect on the generation of the most power they can achieve – all for one 3.6 second race.

A basis of design
I am often asked to substantiate our talking points regarding the true power of our S-Series space heater. Utilized in warehouse and manufacturing environments, these units pack a ton of horsepower to offset heat losses caused by infiltration, open dock doors and skin losses inside buildings. Small in stature, we offer units ranging from 250,000 BTU all the way up to 3,200,000 BTU. Being the only unit available that can achieve 160F discharge and temperature rise does raise some eyebrows. Other manufacturers have claimed to be “like Cambridge”, but the simple fact of the design of the unit offering a blow-thru arrangement, it has inherent advantages over every other heating unit in the market.

More efficient design due to atmospheric gains
Bringing in 100% outside air and introducing it to our blower FIRST before raising the temperature is the basis of the S-series unit. Due to this, we often show our engineering community the effect of our fans processing an air mass that is higher in density – thus containing more oxygen; a vital component in clean combustion.  Without diving into the laws of thermodynamics, fans that process cooler, denser air help produce higher BTU outputs than units that pull air thru a burner – where they are processing warmer, less dense air. Cambridge is the only manufacturer to build its own burner - a fully stainless steel unit - while keeping the mechanical components out of the hot air stream leading to a longer life-cycle of the components.

Healthier buildings using 100% outside air
Indoor air quality is a hot topic lately, largely due to end-users wanting healthier working environments for their most precious asset - their people. Business continuation is dependent on having a consistent and healthy work force and recirculated air inside of spaces isn’t healthy. To offset unhealthy indoor contaminants that build up in spaces that use recirculated air, proper use of HVAC units bringing in 100% outside air is paramount. Recirculation units also offer a lower temperature rise, and need to run for much longer periods of time to offset heat and pressure losses inside of spaces. This is wasted energy.

High performance support
There’s no questioning the 400+ building and case studies we’ve performed in a variety of markets with solid data to support worker comfort, more even temperatures and gas and electrical savings over other technologies out there.  Our contractors have come to love the fact that we make our S-series units the most complete heating and ventilation package there is in the market – taking a lot of the guesswork out of their day searching for missing pieces or parts they thought they were getting. Our support team of engineers, technical trainers and technical advisers are there to help our contractor and engineer community with on-site or virtual training, developing the next solution or running a heat load with layout; giving our customers the confidence they need, knowing the factory is backing them up.

As a manufacturer of industrial HVAC equipment, we know quite a bit about the problems that poor indoor air quality within your facility can have on your employees during hot summer months. Trying to achieve temperature relief within your facility when it is 100° F outside, and even hotter inside, requires more than opening your dock doors and pulling hot air through your facility while running HVLS fans. For most facilities, including ours, the equipment that is running inside the facility provides additional heat gain that can drive indoor temperatures well above the 100° F outside air temperature. When this happens within the facility your productivity, quality and even safety may be affected. Your ability to retain quality employees can suffer as well as your ability to hire new talent can be difficult as well.

Our “Enriching Lives” brand promise is something that we take seriously and strive to provide to all those that we interact with on a daily basis. You know the old saying “Talk the Talk, Walk the Walk?” Well, it dawned on us that we were telling our customers that they should be providing healthy working environments for their hard working people when in reality we weren’t doing it ourselves. How could we expect our customers to take us seriously about IAQ if we didn’t? That’s when we decided to take our own advice and install our ESC two-stage evaporative cooling solution in our own facilities in an effort to provide temperature relief for our manufacturing employees during the hot St. Louis summer months.

What we hope to achieve with our new ESC Two-Stage Evaporative Unit investment
By installing our largest ESC 2-stage evaporative unit in our existing facility in Chesterfield, MO and our new facility in Wentzville, MO we can now provide temperature relief for the team members in our manufacturing facilities. The goal will be to decrease the temperature within our manufacturing environments on the hottest days of summer from what use to be an internal temperature of >100° F to a more reasonable working environment of < 85° F. Keep in mind that those 100° F days only happen about 14 days throughout the summer in St. Louis so we should have excellent IAQ throughout the hottest 90 days of summer.

The process to get the ESC-Series unit installed
The process that we went through to install the unit at our facility is no different than what any other facility would go through. We had to conduct a facility review and analysis and then a system design to provide us with the needed temperature relief required for our buildings. We then had to fabricate the custom HVAC solution needed to meet our requirements and specifications, and finally, we worked with a local HVAC contractor to successfully complete the installs. Due to the size of the unit on our Chesterfield facility it required a crane to lift the unit into place. 

Here is a quick time lapse video of the install.

See it for yourself.
If you want to see how well the technology works check out our website this coming spring. We will have a live webcam/page showing how the technology is working. We will have the actual outdoor temperatures, the discharge temperature of the unit and the indoor facility temperature real-time on our website. All in an effort to show that the technology works even in a hot - high humidity climate as St. Louis, MO. You know what they say, "The proof is in the pudding."

At the end of the day we focus on helping leaders in warehouse and manufacturing create healthy working environments for hard working people. If you would like to learn more about how we can help you achieve this goal join us for a virtual or in-person tour where we will talk about our evaporative platform that is creating a better working environment right here at our own facility.
