Pulsafeeder—MicroVision Cooling Tower Controller with Toroidal Probe

Pulsafeeder—MicroVision Cooling Tower Controller with Toroidal Probe

Cooling towers are heat removal devices used to transfer process waste heat to the atmosphere.  Cooling towers may use air and the evaporation of water to remove heat and cool the working fluid to near the air temperature. Cooling tower water systems are subject to corrosion, scaling, deposition, and biological fouling. This increases operating costs due to downtime, equipment replacement, and increased water and energy usage. Typically biocides and inhibitors are added with the use of Pulsafeeder chemical metering pumps and controllers to effectively treat the water.

The MicroVision Cooling Tower Controller with Toroidal Sensor Technology is a microprocessor based conductivity controller with selectable timer and dual biocide control. Designed specifically for cooling tower applications, MicroVision comes standard with the features and functions you need for accurate monitoring and control of cooling tower water. The MicroVision controller is a full function controller in a compact package that won’t break your budget!
