American Standard Ductless Systems Product Catalog A Comfortable, Convenient Solution Built To A Higher Standard.

American Standard Ductless Systems. Reliable Comfort, Precise Control. Designed and built with the commitment to high-quality craftsmanship you expect from American Standard, our ductless systems are easy to install, offer flexibility in design and provide efficiency and economy with two simple components, an outdoor compressor/condenser and one or more indoor units. American Standard ductless systems are an ideal choice as a retrofit for houses without ducted heating systems, for room additions where installing ductwork is impractical or too expensive, or where the main system lacks capacity to expand, as well as for areas of the home that require additional heating or cooling. American Standard ductless systems avoid the energy loss associated with ductwork. Single-zone systems save money because they are separate from the central system and operate only when needed. American Standard ductless systems deliver the reliability you expect. And they also come with innovative features that ensure precision control for maximum efficiency, economy, and comfort. Three levels of filtration keep air clean and healthy. Energy Efficiency American Standard s commitment to quality includes making sure the air you breathe is as free as possible of dust and other contaminants. That s why each indoor unit provides triple filtration. First, a standard filter traps dusts and other particulates; second, an active carbon filter absorbs both physical debris and chemical pollutants. Finally, a catechin additive filter provides anti-oxidation and sterilization to inhibit the development of bacteria. So you not only stay comfortable, you breathe easy. American Standard Heating & Air Conditioning ductless systems use variable-speed inverter technology. This allows the compressor to continually modulate and adjust to the most efficient speed to meet your demands. Set Temperature Active Carbon Filter Polluted Air The variable-speed inverter technology used in American Standard ductless systems is up to 35% more efficient than a conventional singlehow variable-speed inverter technology works. speed compressor. Not Cool Enough Higher efficiency potentially allows Cools Room for energy savings In Less Time while maintaining desired comfort levels within your home. Catechin Filter Clean Air Robust Grill New strong hot dip galvanized steel grill prevents damage and has no negative impact on airflow. Comfortable Too Cool Inverter Type Small Temperature Difference Non-Inverter Type Unique properties of the Catechin filter The catechin additive is abstracted from natural green tea, providing a long-lasting sterilization of dust and removing up to 95% of potentially harmful bacteria. Intelligent Defrost Auto defrosting improves the system s heating efficiency and helps you save power. Twin Rotary DC Compressor The brushless compressor provides better balance, lower power consumption and higher efficiency. Single Zone Special anti-corrosion coil treatment increases durability and ensures continued efficiency (standard on all heat pump models).
