Wastewater and other refrigeration

Municipalities can reap savings by improving the efficiency of water and wastewater treatment facilities.

Adaptive refrigeration controls and fast acting doors can help to reduce refrigeration costs.

Our Wattsmart® Business program can partner with you to achieve significant cost savings with energy upgrades. 

The City of Selah, Washington, is saving $54,500 in annual energy costs with upgrades at its wastewater treatment plant.
