International EPD System Database lists Maxwell
HTMS are pleased to announce that after extensive due diligence by third-party environmental product specialists, Maxwell’s Life Cycle Analysis (LCA) has been approved and accepted by the International EPD System for listing on their database and website.
The full declaration is available here: https://www.environdec.com/library/epd11974
For most installations of Maxwell in Chilled Water Systems, the CO2 breakeven is less than one year on CO2 emissions saved, compared to the emissions generated during manufacturing and use of Maxwell, as shown in the LCA calculations. In many cases, the breakeven is just a few months.
The LCA assesses environmental impacts associated with all stages in the life cycle of a commercial product, process, or service. including materials procurement, production, shipping, installation, and End of Life (EOL). Maxwell is fully recoverable from the system fluid, and recyclable.
