Johnson Controls launches new 27.5 – 50 ton rooftop units
By Megan Hoegler
Johnson Controls has launched a new series of 27.5 – 50 ton commercial rooftop units with smart controls for optimal efficiency.
Select rooftop units from Johnson Controls feature a prepackaged Smart Equipment controls platform with a full array of user-adaptable parameters. Some units are also offered alongside Johnson Controls’ Premier platform to deliver a complete and competitive offering for this tonnage range, with select units exceeding the Department of Energy’s 2023 Energy Efficiency Standards by up to 22%.
Features of the rooftop units include; 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 range of heating options, including staged and modulating gas; easy to use controls and a competitive replacement opportunity with the same footprint as the majority of similar tonnage-range units in the field – minimizing the need for costly, leak-prone transition curbs.
Units are optimized with the latest proprietary advances in modelling technology to help preemptively identify issues, and an optional Mobile Access Portal offers remote diagnostic monitoring. 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.
