Comfort Inn Boston / Logan Installs Chemical-Free Electronic Water Treatment System for Cooling Towers & Heat Exchanger
The Comfort Inn & Suites Boston/Logan International Airport has installed a FlowMark “chemical-free” (also called “pulsed-power”) water treatment system for its cooling tower and heat exchanger. The FlowMark system, installed by Conservation Solutions Corporation (CSC), has sharply cut water use and eliminated the need for hazardous chemicals to control calcium, bacteria, scale, corrosion and biofilm.
“Chemical-free” water treatment systems are used to treat cooling towers, chillers, heat exchangers and evaporative condensers. They replace chemicals with an electronic field. This website describes how they work. “Chemical-free” systems have the best payback for hotels with cooling towers and chillers.
The Comfort Inn’s new system cost $6,300 to install and saves the hotel roughly $5,685 per year.
