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 efficiency directly translates into reduced natural gas usage compared to other technologies resulting in less carbon emissions from the facility.

What is HTHV?
High Temperature Heating & Ventilation (HTHV) Space Heating Systems are designed to meet a building’s ventilation and space heating requirements while maximizing energy efficiency. The blow-thru design, with 160°F maximum temperature rise and discharge temperature, delivers more usable heat and thermal comfort with minimal temperature variation throughout the heated space. 

Meeting ASHRAE compliance with 100% outside air.

ASHRAE 62.1 requires outside air for human occupancy through mechanical ventilation or natural infiltration. The air load is a significant portion of a building’s heat load, but in a direct-fire ventilation system (as in the S-Series), there are no flue losses and units have a 92%-100% AFUE rating as compared to 60% - 83% AFUE ratings of indirect-fired systems. Moreover, every degree above space temperature is usable for conduction losses.

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.

Reducing our own carbon footprint with solar panels and evaporative cooling

As part of our corporate social responsibility, we know we have to be stewards of our environment, and for nearly six decades, have invented and brought to market some of the most energy efficient HVAC technologies available in the manufacturing and distribution market segments. Our heatingevaporative cooling and ventilation technologies alone operate at 40%-65% savings versus traditional technologies.

Our systems make a big difference for each individual facility through operational cost savings, but the true environmental impact is when 55,000 of our facility installations compound for massive electrical and natural gas savings.

Complementing our own HVAC system performance, Cambridge sought out the opportunity to install solar panels in support of the energy reduction mission. Our CEO John Kramer says, “When the solar opportunity came about, I jumped on it because energy savings will have an impact on our business, on our community and on the world.” He went on to say, “Cambridge exists to enrich the lives of others and this move has an impact on future generations. Enriching lives is not just about the here and now. It has a longer-lasting impact.”

This also drove the decision to invest in an ESC-Series Evaporative Cooling unit to cool our building while using a fraction of the energy that traditional cooling methods use.

Our solar story

The Cambridge solar installation on our plant roof in Chesterfield, Missouri - consisting of 424 individual solar panels - is one of the largest solar installations in our city. On an average week, our panels yield 600 KWH, giving us the ability to cut down on our emissions drastically. Since the installation, the solar panels have saved 262 t of carbon from being emitted from our facility - equal to the yearly output of over 34 homes or 103 passenger vehicles. Moreover, the savings have amounted to around $2,200 a month in electrical savings and are enough to cover 10% of our total electric consumption.

Never Done Improving

Cambridge believes in continuous improvement, and we aim to find new and innovative ways to better our environment consistently. Whether through large projects such as solar panels or finding small ways each day. No matter the size of the project we are dedicated to enriching the lives of those around us and of generations to come.

As we look out over the next ten years, we will continue to share stories about energy transformation within manufacturing and distribution businesses. New technologies enable us to share building performance characteristics in real-time so that more leaders are inspired to change their working environments for their people while simultaneously serving their communities and the planet with energy footprint reductions. “This is my passion, and our leadership team is committed to it,” says Kramer.

Cambridge High Temperature Heating & Ventilation (HTHV) Space Heating Systems are designed to meet a building's heat and air load requirements and be energy efficient. 

Discharge air from the S-Series HTHV Heater creates a large volume of fresh, warm air flowing throughout the building which eliminates higher ceiling temperatures and uncomfortable drafts. The S-Series Heater utilizes 100% fresh air to dilute contaminants generated within the building. This virtually eliminates air quality problems associated with infrared heaters or conventional air heating systems that recirculate indoor air.

As a manufacturer of products that use natural gas, we support the growth of RNG and its use to reduce GHG emissions.

Cambridge Air Solutions is a partner in the vision of improving air quality and the environment – inside and out. We recognize renewable energy is an increasingly important part of a clean energy future for all. When people think of renewable energy, they think of solar, wind, and hydropower. It should be noted that Renewable Natural Gas (RNG) is also a clean source of energy. RNG is reliable and always available – unlike solar and wind which is dependent on the weather and time of day.
