Most Commonly Asked Questions About THE UNICO SYSTEM
1. Where is The Unico System best suited and what are its benefits?
The Unico system can be used to cool or heat homes or buildings that have no ductwork, inadequate ductwork, or little space for ducting is available. Also, in any application where superior indoor comfort is desired. The Unico System adapts perfectly to any type of residential setting such as homes, condominiums, or apartments. It also adapts to many commercial and industrial applications. The Unico System operates like any other central air system, but with greater benefits.
2. With high velocity air, will the system be noisy?
The Unico Systems 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. Special sound-attenuated supply ducts ensure quiet operation.
3. What sizes are available?
Currently, there are 1 to 5 tons of nominal cooling & heating.
4. What condensing unit must be used with The Unico System?
One of the best selling features of the Unico System is that it can be used with any condensing unit of proper capacity. There are hundreds of matches listed in the ARI Unitary Directory. More thank likely, you can use the condensing unit you are most familiar with.
5. How many BTUs are there per outlet?
Each outlet is capable of delivering up to 40 CFM (19 L/s) with a capacity of 2000 Btu/hr (0.6 kW) cooling and 4000 Btu/hr (1.2 kW) heating (with hot water. We recommend that a minimum of 6 outlets per nominal ton be installed. However, this will vary depending on the design of your system and your load requirements.
6. What are the types of outlets, and where should they be placed?
There are two types of outlets currently available: the round supply outlet (UPC-56B) and the slotted outlet (UPC-66). Ideally the outlets should be located in the ceiling 5-inches from the wall or corner. If conditions prohibit this, they can be placed in the floor or sidewall. The round supply outlets are also supplied in an unfinished solid oak face that can be stained to match a wood floor.
7. What types and sizes of ductwork are there?
The system requires only two types of duct - the main plenum (7-inch [178mm] or 9-inch [229mm] inside diameter) and the supply tubing (2-inch [51mm] inside diameter flexible duct with insulation).
8. How long can my main plenum and supply runs be?
The main plenum should be run as far as possible to keep supply runs as short as possible. The supply runs may be virtually as long as you need them to be. However, there will be reduced cooling capacity in long runs.
9. How does Unico provide return air?
The Unico System's return duct is like a conventional system, only smaller because the system uses less air. A single or multiple return system can be used, depending on the project needs. It can also provide 100% outside air.
10. Can I heat as well as cool with The Unico System?
Yes, there are three ways to heat with our system:
- Hydronic (hot water) coil
- Add-on heat pump
- Electric duct heater
