• Is it “Heating & Ventilating Technology” or “Ventilating and Heating Technology?” That is the Question!

  As our clients navigate HVAC system design for high bay facilities such as distribution centers or industrial manufacturing plants, they are often asked to recommend a design that accomplishes 3 key deliverables. 1.) Meet variable ventilation requirements 2.) Meet heating requirements / (Consider air load and conductive load and comfort requirements) 3.) Evaluate redundancy to eliminate production and/or service interruptions As a manufacturer of high efficiency heating technologies (S-Series, SA-Series, Infrared) and ventilating technologies (M-Series, M-Series w/Cooling) we first seek understanding regarding how the building will be operated in order to recommend a heating platform, a ventilation platform, or both. While the core technologies are both 100% outside air, direct fired gas heaters, there are differences in system performance that will impact EE (energy efficiency), thermal comfort, and system installation cost. When there is a high level of CFM being exhausted due to processes inside a manufacturing facility, making up that building air loss with mechanical ventilation or inbound CFM is critical to balancing the air load of the building. Direct Fired Make-Up air systems with variable air ...

• The Advantages of HTHV Heating for Industrial Facilities

  Industrial Heating with High Temperature Heating & Ventilating (HTHV) To heat an industrial facility, it is critical that the system is designed with worker safety and lowered operational costs and energy consumption top of mind.   HTHV is a technology classification created by the Department of Energy (DOE), producing a heating system capable of a discharge temperature greater than or equal to 150°F and a temperature rise greater than or equal to 140°F. HTHV heating systems are capable of effectively heating and ventilating both large commercial and industrial spaces, reducing energy consumption and increasing energy savings by 20-70% depending on the building, location, application, and installation. Most importantly, by using 100% outside air and direct-fired technologies, HTHV products provide a ventilation process that delivers superior indoor air quality for employees/building occupants. Direct-fired 100% outside air technologies Temperature stratification is a major issue in all high-bay industrial applications in the wintertime and must be addressed through the proper selection of destratification technologies. A study published by the Department of Energy titled Field Study of High Efficiency Gas Heaters looked at the energy savings accomplished with HTHV ...

• Choosing the Right Heating System for your Facility

  Is the heating bill for your plant or warehouse too high? What about cold dock door areas and unbalanced temperatures? Is negative building pressure a problem? Do your employees complain about it being too cold making it harder for them to do their job? Do you have high maintenance costs from existing heating equipment? These are just a few common problems that result from selecting the wrong heating system, misplacing your heaters so they can’t reach their full potential or using obsolete technology. What factors determine the best space heating system? Everyone wants a heating & ventilating system that meets their unique requirements at the lowest total cost. Before selecting a heater, define the heating/ventilating requirements and understand all the cost factors that determine the true lowest total cost solution for a specific facility. BOILER SYSTEMS One of the oldest forms of heating, boilers have been in existence since about the 1800’s and are still a preferred system of heating in large industrial facilities where remote plants deliver steam and hot water to satellite locations to circulate through heat exchangers. These exchangers ...

• Indoor Air Quality…It Really is Important

  According to the Environmental Protection Agency the average American spends 93% of their life indoors…. 87% is spent indoors at their work and home and the other 6% is spent in their automobiles. With that much time spent inside we should all be more concerned with Indoor Air Quality. Recently Cambridge Engineering’s Doug Eisenhart published a post about IAQ that focused on the effects of temperature and productivity of a workforce because ambient air temperature is an IAQ factor. Doug was spot on with his comments about productivity and its correlation to temperature. Along with temperature the quality of the air from indoor pollutants is also an important IAQ factor that needs our attention. Pollutants such as volatile organic compounds (VOC), particulates and carbon dioxide, to name a few, can not only affect short term productivity but can also have long lasting negative health consequences to those working in that environment. One way to alleviate these types of IAQ problems is to have the building properly ventilated through the use of mechanical ventilation of filtered outside air. By ...

• Building Owners Earn Big Tax Break for New HVAC

  We recently heard some great news from our tax advisors: Cambridge Engineering customers can immediately deduct 50 percent of the cost of our HVAC equipment when it is installed as a retrofit in a commercial building. The new rule applies to a variety of building improvements and renovations made in 2016 and 2017 – and HVAC equipment is included as an eligible deduction. This is a big win for building owners! If you’ve been considering replacing your facility’s old or inefficient space heating and ventilation equipment, now is the time to do it.  The 50 percent “bonus deduction” will taper down to lower percentages after 2017, and will go away completely in 2020.               Accelerate Your Depreciation on Building Improvements This gift from the IRS marks a significant change from past deduction allowances. HVAC equipment has always been considered part of the physical structure of the building, so until now it could not be depreciated at an accelerated rate in the same way that capital equipment can be depreciated. In the past, building improvements have been depreciated over 39 years. That’s ...

• People Comfort - How Does It Effect Your Bottom Line?

  For the last 3 years my team has been traveling North America visiting with Cambridge Engineering’s, Sales Representatives to spread the word about options available to Building Owners, Building Operators, Design Engineers, Contractors and Utilities when recommending and selecting heating and ventilation solutions for their building or retrofit projects. We have been attempting to call out 3 core concepts for the key influencers when considering improvements to their buildings. 1.) Safety - Use of 100% outside air, direct fired HTHV and MAU technology is inherently safe. Ventilation and Heat are provided by the same blower that cannot be separated. These technologies can improve indoor air quality. Ventilation is the key to safety, preventing the buildup of products of combustion. 2.) Energy Efficiency - HTHV technologies provide the highest btus/cfm ratio thus creating more net useable btus or heat to satisfy the air load and the conductive load in high bay warehouses, distribution centers and manufacturing facilities. 3.) Lowest Total Installed Cost - HTHV technologies deliver 3 system in 1 piece of equipment. HTHV technologies deliver A.) Heat, B.) ...
