Five Star’s Bes-Tech Digi-RTU Controller

Advanced, next generation controls will be a standard element of all new RTUs, but today there are various ways to access these new technologies. Five Star is very pleased to offer Bes-Tech’s Digi-RTU controller. Radical savings is the best way to describe what to expect.

Digi-RTU HVAC Roof Top, Water/Air Source Heat Pump

Digi-RTU is a control package designed for rooftop unit retrofits. The technology was developed for use on single-zone packaged rooftop units with either gas/electric heat or air source heat pump configurations. Using load-matching technology, the Digi-RTU can turn a constant volume, constant capacity unit into a variable capacity system. Studies indicate that implementation of the Digi-RTU system can result in a 40% to 60% average reduction in energy consumption and 30% to 60% decline in demand. These savings are created by modulating the speed of both the compressor(s) and indoor fan. Due to the lowered capacity, the Digi-RTU reduces unit cycling, creating spaces that have more controlled humidity levels. The Digi-RTU design includes temperature safeties and oil return logics that ensure its safe operation.

Five Star Mechanical’s – RTU Tune up

United States Department of Energy and ASHRAE both agree that “retrofit commissioning” of an HVAC roof top unit (RTU) is possibly the most cost-effective expenditure a business owner can make to save money and lower energy demand. Five Star’s RTU Tune-Up will get equipment as close to factory specs as possible. Our tune-up will show lower energy costs, but the tune-up is just the first step to radically lowering the energy demands of any RTU.
