Digi-RTU Roof Top Unit Controller and Retrofit Kit The Digi-RTU Roof Top Unit Controller ensures conditioned space thermal comfort, humidity control, and indoor air quality by modulating the compressor staging, supply air temperature, condenser fan speed and number of fans in operation (Optional), airflow rate, and outside air intake. A VFD installation is required for the supply air fan. The Digi-RTU Controller can be used for retrofitting existing systems and implementing in new systems. The Digi-RTU eliminates compressor hunting and vapor re-evaporation using innovative capacity and load matching technologies. Excellent room humidity and temperature control is guaranteed. The Roof Top Unit Controller extends the compressor life more than 5 years. It makes operators’ job much easier and operating cost much cheaper. The Roof Top Unit Controller reduces the system energy (compressor, supply air fan, and condenser fans) consumption as much as 50%. You have an equivalent water cooling system without paying the initial investment and cost of maintenance. The Roof Top Unit Controller is a truly green makeover for 70% of commercial buildings where roof top units are currently installed. |
