Air-movement systems

Compact and energy efficient, the Airius Thermal Equalizer is a low-wattage air-movement system. Suspended near a ceiling, the most commonly used model is a nearly silent air turbine that drives a column of hot air to the cooler floor below. The hot air mixes with the cooler air and generates a series of air currents that circulate the air from ceiling to floor continuously. This process creates a constant equalization of air temperature in a process called thermal destratification, or thermal equalization, allowing thermostats to be lowered during winter and raised during summer. This results in a substantial reduction in energy consumption. Within 24 hr, floor-to-ceiling temperatures are regulated and maintained within 3°F. The average-size model uses about the same amount of energy as a 35-w light bulb. When using the units in a standard 100,000-sq-ft facility that typically utilizes an electrical-energy source based on coal or natural gas, a 10-ton-per-year reduction in carbon emissions can be achieved. The air-movement systems support the efficiency and life span of HVAC systems, which do not need to run as often because temperature differentials between floor and ceiling are eliminated.

Evaporative coolers

Low-profile industrial/commercial Kube coolers employ FreshWater slinger-wheel technology, which evenly distributes evaporative atomized water across air inlets to ensure efficient cooling. Evaporative-cooling pads are eliminated, minimizing the risk of airborne pathogens, mold spores, and odors.

Scroll-compressor chillers

Now available in 30- to 180-ton models with R-410A refrigerant, air-cooled scroll-compressor chillers provide efficient cooling. Useful for schools, government offices, and other projects, the chillers meet or exceed ASHRAE Standard 90.1 for energy efficiency, with an EER of up to 10.3 at full load and up to 14.7 at part load. The units can be customized to fit specific needs in various ways, such as by adding a unit-mounted pump package and a remote evaporator.

Geothermal heat pumps

With unit sizes from ¾ to 25 tons, the Envision line of geothermal heat pumps helps building owners reduce energy costs by tapping into the energy found beneath the earth in a ground-loop application or by utilizing a building's internal heat energy by means of a boiler and a cooling-tower-water loop. Two-speed compressor technology improves indoor-air quality by allowing extended run times.

Wet-rotor circulators

Oil-less and seal-less, the Magna wet-rotor circulator is cooled and lubricated by the water it pumps. Its integrated variable-speed drive automatically adjusts performance to meet demand and save energy. End users will see lower electricity bills because the unit's permanent magnet rotor and high-efficiency impeller save energy. The circulator is useful for heating and snow-melt applications.

Multisplit systems

The multisplit product line now offers a two- or four-port condensing-unit platform. The systems feature an “intelligent eye” function that enables the unit to reduce the temperature automatically when no one is detected in a room. Long piping length and flare connections allow for extra installation flexibility (230 ft combined piping length). The systems are optimized for R-410A refrigerant.
