Stating that it improves indoor environmental quality (IEQ), while delivering energy-efficient performance, Johnson Controls has announced the launch of its new Enviro-Tec-brand, floor-mounted fan-coil unit.

According to Johnson Controls, available in concealed, exposed or sloped-top configurations, the unit includes factory-mounted DDC control or unit-mounted digital thermostats. Controllers and actuators are wired via plugged wiring harnesses with colour-coded plugs and wires. In addition, factory-mounted piping packages arrive on the job site with actuators wired to the controller.

The new fan-coil unit improves IEQ by offering the following, claim Johnson Controls:

• High-efficiency MERV 8 or MERV 13 filters
• Reduced sound levels
• Stainless steel coil casings
• A sloped, stainless-steel drain pan that avoids standing water
• Standard closed-cell foam insulation that exceeds the insulating value of fiberglass and does not wick condensate
• Dehumidification control via reheat options and thermostat control schemes

Other product features include:

• Optimised coil circuits and fan and motor combinations that contribute to 30 to 50% less energy than comparably sized competitive units
• Choice of a programmable thermostat that uses a clock for unit setback or a passive infrared (PIR) sensor that senses occupancy to determine setback to help manage energy consumption
• Wireless networking capabilities that enable communication with a building automation system
• Airflows ranging from nominal 200 to 1,200 CFM with performance certified as complying with AHRI Standard 440; sound data tested in accordance with AHRI Standard 350
• Cabinet heights and widths that can be varied in one-inch increments up to 12 inches to accommodate existing architectural features
