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.
