KE2 Smart Thermostat


The KE2 Smart Thermostat is an energy saving refrigeration controller for walk-in freezers and coolers, with remote monitoring and diagnostics. Recent field tests have shown more than 20% energy savings when the KE2 Smart Thermostat is used on a refrigeration system that is currently operating efficiently. The KE2 can be installed for new equipment or upgrade of existing refrigeration equipment.
