Fan Coil Units For Chiller Air Conditioner & Hydronic Heating & Cooling

Ultra-Slim 5.1" Ceiling Mount DC-Inverter Fan Coil Units.

Ultra High Efficiency Fan Coil Units w/ DC Inverter Fan Motors

DC-Inverter fan motors run more efficiently and use less power than regular fan motors. Additionally, they are far quieter than a standard fan unit, you can hardly hear them running. And using a hermetically sealed fan motor means years of trouble free service because dust, salts, acids, and moisture cannot get inside. Did we mention more efficient? DC-Inverter fan motors use up to 75% less electricity to do the same job. Chiltrix Ultra-Slim DC-Inverter CXI FCUs are 110-130V 60Hz.

The Chiltrix CXI-series FCUs are the thinnest and quietest ductless chiller fan coil units available. They also use far less electricity to operate than any standard fan coil unit. The HW series is a standard high wall design of standard efficiency. The Chiltrix CX-series chiller heat pump units can work with nearly any brand of fan coil unit, ducted or ductless, as well as hydronic in-floor systems.

Central Ducted Hydronic Systems:

Ducted forced air systems are less efficient than ductless fan coil units due to static pressure drop and duct thermal loss. Ducted systems require a centralized thermostat,and cannot take advantage of individual zones in each room like a ductless system. In new construction, or when adding air conditioning to a building that has no current duct system, the installed cost of a ductless system will be about the same, or less than, installing with a duct system. However, if a central ducted system is your best choice, the Chiltrix system combined with a FirstCo DC-Inverter powered VMB will be your most efficient choice.

About DC Inverter Fan Motor Technology

Whether it is used for a compressor, a pump, or a fan motor, DC Inverter motors are well known for being more efficient. They also run cooler, last longer, and produce a much lower sound level.

DC Inverter motors have no actual inverter in them, AC power runs through a rectifier circuit converting it to DC power. The DC power is then pulsed in varying frequencies to rotate the motor. The higher the pulse frequency, the faster the motor turns.

DC inverter motors are not only up to 20-40% more efficient at a given speed, they also provide the ability to efficiently match the motor speed to the real-time demand saving even more energy.
