Optimized static regain design method that uses all available total pressure to balance the system and reduce duct cost (see McGill AirFlow’s Engineering Report No. 144)

 

Unparalleled database that includes many types of fittings with performance data derived from actual laboratory testing

 

User-selected maximum and minimum velocities

 

Round or flat oval pre-sizing of any (or all) sections

 

Half-inch duct sizes through 15 inches

 

Round and/or flat oval designs

 

Automatically designs with flat oval whenever user-selected height restriction is exceeded

Fitting default selection (automatically uses less expensive fittings for better balancing where appropriate in nondesign legs)

 

Fitting selection override at any location in the system

Component pressure losses entered as either in-line losses or loss coefficients

Allows entry of outlet static pressure requirements

Entry losses entered as either total pressure losses or loss coefficients

User-selected diversity factors for any nonoutlet section

System can be designed to operate at a selected target pressure

Maintains minimum design carrying velocities

Corrects for non-standard elevation and temperature
An acoustical program that does the following:
 

a.

Accepts user-defined fan sound power levels or estimates the fan sound power levels by established practices
 

b.

Accepts entry of additional attenuation and regenerated noise at any point in the system
 

c.

Calculates all forms of attenuation and noise regeneration due to system components and airflow conditions
 

d.

Calculates insertion loss of 1-, 2-, and 3-inch-thick lined duct and elbows
 

e.

Determines path attenuation requirements for each terminal section based on user-selected NC levels

Products match SMACNA high- and/or low-pressure gauge requirements

Entry of duct material handling class

Automatic selection of duct gauge and reinforcement based on material handling class and duct pressure

 

Input data listings
Sectional analysis report provides the following data for all sections:
 

a.

Duct size
 

b.

Volume flow
 

c.

Velocity

d.

Static or total pressure drop (or regain) through the takeoff or branch fitting

e.

Cumulative pressure drop through all duct fittings

f.

Duct pressure drop

g.

Component pressure drops

h.

Cumulative static or total pressure drop (or regain) for the section

i.

Outlet or inlet static pressure drop

j.

System static or total pressure at the entrance to each section

 

System analysis report

Acoustical analysis report

Report format for either static or total pressure (user selected)

 

Separate report of excess pressure at all terminal or entry sections (provides an indication of balancing and locates the system design leg)

 

Average and highest excess pressure in system shown on balancing report

 

Complete bill of material

 

Complete project information

 

Report includes suggested specification

 

Unprecedented design guarantee
