Werner Enterprises Reduces HVAC Energy

November 11, 2014 By Linda Hardesty

Bes-Tech energy manageTrucking company Werner Enterprises installed 29 Digi-RTU HVAC rooftop optimization kits from Bes-Tech at Werner’s corporate headquarters in Omaha, Neb.

With the optimization kits, the 29 installed units are expected to achieve a reduction of 565,000 kWh per year, or 51 percent, as well as a reduction of 9,200 Therms, or 17 percent.

In addition, the Omaha Public Power District provided a kW incentive for the 147 kW reduction in peak demand.

The Digi-RTU integrates with the existing economizer, modulates the supply fan, modulates the compressor speed, and regulates the indoor air CO2 level. By intercepting heating and cooling calls, the Digi-RTU’s patented technology manages the compressor and fan speeds to match the space load requirements.
