Johnson Controls has launched a series of 27.5 – 50 ton commercial rooftop units designed with smart controls to deliver performance and efficiency, and extended equipment life. Select rooftop units from Johnson Controls feature a pre-packaged Smart Equipment controls platform with an array of user-adaptable parameters, and the units integrate with the Verasys building controls system for system control.
Select rooftop units are offered alongside the Johnson Controls Premier platform to provide a complete offering in this tonnage range. Select rooftop units exceed Department of Energy (DOE) 2023 energy efficiency standards by up to 22 percent while surpassing current DOE 2018 levels by up to 39 percent. In addition, the units offer up to 31 percent greater part-load efficiency (IEER) than comparable models and up to 15 percent greater IEER than the Millennium legacy product. Coming later in 2020, the four-stage IntelliSpeed models will bring even higher efficiencies, with energy costs reduced to industry-leading levels.
Units are optimized with the latest proprietary advances in modeling technology to help preemptively identify issues, and an optional Mobile Access Portal offers remote diagnostic monitoring for fewer trips to the job site. In addition, single-side access to all serviceable items provides ease of service that is further simplified with accessible connections, service ports, coil cleaning hatches, hinged access panels, convenience outlets, service disconnect switches and optional service valves.
- Multiple airflow strategies, including two-stage constant-volume, two-stage with IntelliSpeed fan control, four-stage variable-air-volume and four-stage with IntelliSpeed fan control.
- A broad of heat options, including staged and modulating gas heat, stainless steel heat exchangers and electric heat.
- Easier-to-use controls that include a start-up and commissioning wizard to simplify the installation process.
- Competitive replacement opportunity with the same footprint as the majority of similar tonnage-range units in the field – minimizing the need for leak-prone transition curbs.
Units are supported by the Johnson Controls Commercial Application Support organization, which provides expert pre-sale consultation, and the Johnson Controls Commercial Technical Service team, which provides leading field support. These teams offer technical and field support throughout every aspect of ownership from selection, installation, replacement and service.
