Manufacturer balances air pressure with natural gas savings

Even with the air systems running at full capacity, Erik Karn, upkeep and centers supervisor, DMH, observed an imbalance in the structures air pressure. Energy Trust carried out a research study of their system to explore the most reliable way of returning air to the center. By returning the dust collection air, DMH was able to turn off one of its makeup air systems and turn down the second unit by 50%, enhancing internal air pressure and minimizing energy required to warm the building.

” Reducing energy usage was not our very first goal, however it is an important outcome,” said Karn. DMH is now saving around 39,000 therms and around $15,000 in gas expenses every year. Cash incentives from Energy Trust assisted defray nearly 60% of the job expense.
According to Karn, DMH has actually also realized electric cost savings of about $5,000 each year by dealing with Bonneville Power Administrations Energy Smart Industrial program and its regional electrical energy. Powering down the makeup air units has actually decreased electrical energy required to sustain the systems motors and fans.
” Our problems with air balance and climate control are resolved,” said Karn. “Employees are comfy. Theyre happier and more productive.”

Air exhausted from the system was replaced with outside air heated up by two cosmetics air units.

Improving air balance within its production center, and improving environment control for staff members, were the primary objectives of DMH Inc.s investment in a custom-made heat healing system.
Mills, planers, and sanders located throughout the plant create wood dust and particulates that are caught by a dust collection system. Air tired from the system was replaced with outdoors air warmed by two make-up air systems.

Even with the air units performing at full capacity, Erik Karn, upkeep and facilities manager, DMH, observed an imbalance in the structures air pressure. Negative air pressure inside the center was causing doors to slam, breezy conditions, and inconsistent interior temperature levels. Workers would prop open exterior doors to compensate, increasing the need for heating in the cold weather condition months.
DMH had actually dealt with Energy Trust on a previous task to install a regenerative thermal oxidizer, which cleans up volatile organic substances from commercial exhaust. Pleased with this first project, DMH turned to Energy Trust once again for assistance with their brand-new difficulty.
Energy Trust performed a research study of their system to check out the most effective way of returning air to the facility. A distinct brand-new system was installed that returns filtered, conditioned dust gathered air back into the building safely. By returning the dust collection air, DMH was able to shut off among its makeup air units and deny the second unit by 50%, enhancing internal atmospheric pressure and decreasing energy needed to warm the building.
