Condensate Harvesting Systems for Commercial and Institutional Buildings
Condensate is a “Free Resource” Available Everywhere
Every commercial building with a forced-air cooling system has one thing in common – as air is passed over cold coils from the compressor, moisture in that air will condense and “condensate” will drip to a collection pan below.
In many cases, that condensate is sent to the municipal sewer system, wasting a valuable source for reuse systems. In a typical commercial building cooling 100,000 square feet with 150 tons of cooling capacity the annual condensate collection potential can be hundreds of thousands of gallons. That harvested water can be sent to the evaporative cooling system or used for irrigation or toilet flushing.
If we depend solely on rainwater as a reuse source, we may go days or weeks without a rain event at a time of year when it is hot and we need the most supply. That is the time when condensate is most plentiful, making it an ideal complement to rainwater as a source.
How Much Condensate Could You Harvest from Your Building?
Condensate Harvesting Systems
Condensate harvesting systems are relatively inexpensive and efficient, with an attractive return on investment. That is because large tanks are not required, and the treatment and pressurization capacities are sized for a slow and steady capture and reuse. The collected condensate must be filtered and sanitized to eliminate potentially harmful mold or bacteria like Legionella. Our standard system shown here is truly “plug and play” and is delivered complete on a skid with tanks, filters, sanitation, pressurization pump and controls. The system is designed to accommodate retrofit situations by fitting through standard doorways and freight elevators. Download an information sheet by clicking here, or a specification sheet here.
