Easily Installed in Lofts and Utility Rooms

The UNICO System is a small-duct, small air handler system for central heating, air conditioning (cooling) and ventilation applications. The systems modular air handlers can be easily installed in lofts, utility rooms, voids and crawlspaces. Careful consideration is required for the location of the air handler units (AHU) and the central duct system. From the central duct the sound attenuated 89mm flexible supply tubes easily runs through and around the construction of a new building or existing buildings, where voids or more likely the loft space can be utilised.

Low Noise Minimal Vibration

Our supply tubing is designed to be as quiet and efficient as possible, with a nylon inner core and insulation that absorbs sound. Our air handlers are designed to isolate noise and vibration, with closed cell, sound-deadening insulation. Together, they bring decibel levels to the equivalent of a soft whisper. While you’ll feel the comfort our system provides, you’ll hardly notice it’s running.

Unico System

Draft-Free Even Temperatures

Traditional systems distribute air unevenly, dumping air into rooms, creating drafts and uneven temperatures throughout different parts of the room. The Unico System uses a principle called aspiration, creating a gentle suction around itself that draws the room air into its stream of cooled air. This delivers even, draft free cooling, from room to room, floor to floor, and floor to ceiling. The temperature differential is no greater than 1°C throughout your home.

Comfort by Design

The unique design of its cooling coil means The Unico System removes up to 30% more humidity than conventional air conditioning and heating systems. So, you can keep your thermostat a few degrees higher while feeling the same level of comfort—and that saves on energy costs and creates a much more comfortable conditioned environment which is essential for general well-being. It can also help with productivity and learning in the work space as people perform better in a controlled environment.

What Size do I Need & How Much Will It Cost?

The UNICO System is available in 5 sizes and selection is made once the calculation for the heating and cooling demand has been established. Each system requires the same criteria and approach as it will consist of the same technology and products other than their physical size and performance.

Each project and house type can be very different and whilst two properties may look similar from the outside the construction, U-value and load requirement can be very different. Therefore the price range can vary and we recommend you speak to one of our approved Specialist Partners who will be able to offer further advice about your property and system requirements.

It has the ability to pair with numerous outside condensers, heat pump and boilers as well as mechanical vent and heat recovery systems. As with all installations it is important that your contractor selects products that have been or can be matched to ensure optimum performance and compatibility prior to securing the project.
