Small Duct High Velocity Central Air System by Unico Available at Unique Indoor Comfort Libertyville

1. Commercial Heating, Ventilation & Air Conditioning
• Small ducts – adds
cubic feet to office space,
increases head room; eliminates
or dramatically reduces the need for
unused room between ceiling and next
floor
• Unobtrusive round or slotted outlets (can even
be hidden) come in wood, metal, and plastic finishes.
Outlets either 2" or 2.5" round or 3/4' x 8" slotted
• Quiet – All Systems include sound absorbing duct (sound
attenuator) which is further enhanced with the soft start / soft stop
feature of our Unico System air handlers with SMART Control Board
• Highest comfort in the industry
– No drafts
– Even temperatures ceiling-to-floor, wall-to-wall
– Lower humidity while cooling
– Warm air heat pump
• Most UNICO SYSTEMS air handlers are modular – WILL FIT BETWEEN TRUSS JOISTS. (if necessary)
• Requires less labor to install than conventional commercial systems
• Energy efficient low leakage duct system – less than 2%
• 1/4 the size of traditional commercial ducting
• Great for zoning multiple rooms year round
Design Flexibility – Unico air handlers can heat and cool using chillers,
boilers, DX cooling only and heat pump condensers, geothermal heat
pumps, electric furnace, and Unico’s line of cooling only and heat pump
UniChillers. Unico air handlers are also compatible with the following
SDHV (Small-Duct High-Velocity) is a central air-distribution
system made of very small ducts that deliver
conditioned air into the room using small jets of air that
actively mix the room air without creating drafts.

2. The blower module comes with several different motor and control options as follows. STD (standard model) – the most economical and include a single-speed motor with a variable speed controller to adjust the low air speed delivery. EC1/EC2– is part of the Unico Green Series. This control box includes a super efficient variable speed EC motor with the Unico SCB (S.M.A.R.T. control board). The airflow is completely configurable using a PC.

EC models
Airflow and motor RPM are preset or can be adjusted using the EC Config software. EC motors are available in 110v and 230v.
To determine the airflow when using the single or two-speed motors (-STD models), measure the amperage and look up the airflow in the following table. This is not necessary for the variable speed motors because they are programmed to deliver the airflow that you need.
