The Unico System adapts perfectly to most residential & light commercial applications. Its unique design and flexible tubing mean we can now consider warm air and cooling where previously large HVAC systems would not fit.

The Unico System operates like any other central air system, but with the following important differences and benefits:

1. 1. Air is distributed through small flexible ducts that fit almost anywhere. They simply connect to main duct in the loft or between floors.
   2. Aspirating the stagnant air with small jets of air that eliminates drafts and hot/cold spots in your living space.
   3. The ductwork is optimized for low noise and maximum efficiency.
   4. Increased moisture removal during cooling. Our coils are designed specifically to remove significantly more humidity for a drier home during cooling.
   5. Unico is a truly warm air system – no more “cold blow”. We deliver the air at substantially higher temperatures than a conventional system.
   6. Minimal duct loss. The small ducts are factory insulated and easily sealed. With approximately 1/3 the surface area of a conventional system, duct losses are kept to a minimum when installation in an unconditioned space is unavoidable. All the connections include gaskets which reduces air leakage to 2 percent or less when properly installed.
   7. Options. Unico, has a large number of accessories and options to suit your design and life style.

Unico System is extremely quiet because of its special sound-absorbing insulation. We insulate our air handler and use vibration pads on the system to reduce vibration and add extra sound absorption.

Currently, there are 5 basic system sizes available; a 1218 model with a nominal cooling capacity of 3.5 to 5.3 kW, a 2430 model with a nominal capacity of 7 to 9 kW, 3036 model with a nominal capacity of 9 kW to 10 kW a 3642 model with a nominal capacity of 10 to 14 kW, and a 4860 model with a nominal capacity of 14 to 17 kW.

One of the best-selling features of the Unico System is that it can be used with almost any condensing unit or ASHP of proper capacity. For heating only, The UNICO System can also work with a traditional gas or oil boiler.

The system requires only three types of duct – the main central duct and the aluminium supply tubing, and sound attenuator. The supply tubing is a 51 mm or 62-mm inside diameter flexible duct, wrapped with fiberglass insulation and an outer reinforced aluminised Mylar® 1 vapor-seal jacket. The main central duct is either a 160mm, 200 mm or 250 mm inside diameter, depending on the design and capacity of the system. Your install can opt for either round or rectangular duct of equivalent size.

The main duct run should be designed to keep the supply runs as close as possible to the minimum length requirements. The supply runs may be virtually as long as you need them to be. However, there will be reduced cooling & heating capacity in longer runs. We provide a detailed chart in our application guide to explain this.

The following table shows the average capacity of an outlet for an air-conditioning system with heating. We recommend that a minimum of 6 outlets per 3.5 Kw to be installed. However, this will vary depending on the design of your system, your load requirements and sound expectations.

Outlet Size	Nominal Airflow	Cooling Capacity	Heating Capacity
51mm (2″)	17 L/s	1400 BTU/hr (0.4 kW)	3000 BTU/hr (0.9 kW)
63mm (2.5″)	21 L/s	1800 BTU/hr (0.5 kW)	4000 BTU/hr (1.2 kW)

There are two types of outlets – a round supply outlet or a slotted outlet. Ideally the outlets should be located in the ceiling close to the wall or corner. If conditions prohibit this, they can be placed in the floor or high sidewall.

When possible, balance the system at the take-off. Placing the orifice at the take-off allows the sound attenuator duct to remove any noise caused by its restriction. When the take-off is in a hard to reach area, add a balancing orifice at the outlet. Use balancing orifices sparingly to maximize the airflow.

Yes, the UNICO system is extremely flexible using a range of coils (heat exchangers) so depending on your heat source we will have a number of options for you to consider.
