Nortek Air Solutions brand Mammoth pioneered the use of evaporative condensers in commercial HVAC applications more than 40 years ago and has used this innovative technology in products to significantly reduce the amount of mechanical cooling needed and, therefore, lower energy costs.
How does Evaporative Condensing Work?
Evaporative condensers use the cooling effect of evaporation to improve the heat rejection process. Water is sprayed over the condensing coil from above while air is simultaneously blown up through the coil from below to naturally lower the condensing temperature. The lower condensing temperature reduces the compressor workload.
As a result, your system operates more efficiently and uses far less energy than air cooled alternatives. In fact, the reduced compressor kW draw (25-30%) coupled with demand charge savings (up to 30% of a utility bill in some cases) can result in operating cost savings of more than 40% versus air cooled condensers.
Energy Savings
The graphic estimates the energy savings from evaporative-cooled condensers in four cities using their local weather data and keeping the airside components identical between cities across the USA.
Evaporative condensing and our unique evaporative condenser design offers several benefits in addition to energy savings, the reduced compressor KW draw can lower electrical installation costs, because less wire sizes, disconnects, and other electrical controls are needed. (illustrated below) Plus, repair costs and downtime can be reduced and component life extended, because the compressors work against a smaller pressure differential than air cooled condensers.
Sustainability
Evaporative-cooled condensers promote environmental sustainability. Advanced water-treatment options, including chemical-free systems, are environmentally friendly and can help you qualify for LEED® points.
