Testing and Balancing Using today’s Air Flow Capture Hoods

• A recent independent survey of HVAC contractors revealed:

50% were not satisfied with air flow measurement and recording 37% not satisfied with set up and time to complete the job 87% were not satisfied adjusting air flow 62% not satisfied with how air flow is balanced

• Poor accuracy leads to higher energy costs.• Dwyer decided to take action!!

• Started by thoroughly testing todays air flow capture hoods in Dwyer’s custom in-house laboratory

Laboratory Specifications

First issue discovered:• Diffusers are the primary source

of error!

Action taken:• To build a mobile software application to

to calibrate various diffuser types

A Better Way to Air Balance

The SMART Air Hood™ Balancing Instrument improves the

balancing process

Proportional Balancing Review

• Proportional balancing is an iterative process based on estimating and sometimes guessing.

• Experienced technicians attempt to balance an HVAC system within +/-10% (in most scenarios).

• Experience and skill become critical to reducing the number of iterations for proportional balancing.

Traditional Proportional Balancing

• Predictive Balancing is deterministic!• There are a known number of steps • PredictAir Software Application

“predicts” where and how to adjust the dampers to accurately balance the system.

• Smart Air Hood™ Balancing Instrument– Light-weight and maneuverable (< 6 lbs.)– Ergonomic, less muscle strain– Single Tech can operate– Quad Flow Design Technology

• Minimizes Back-Pressure error• Handheld Interface– Wi-Fi Direct with strong antenna (up to 200 yards)– Diffuser library in the PredictAir™ software

application– Predictive Balancing

SAH Key Features

• Accuracy – Calibrated for diffuser type in the library– Accuracy is ± 3% for any diffuser in the library

• Always operational– Lithium rechargeable battery– 4 AA backups

• Annual Calibration – easy and fast– Snap off Quad Flow sensing grids/ sensor and return – Snap on another recalibrated Quad Flow sensing grid and

sensor, no down time

SAH Key Features

• HVAC Contractors, specifically air balancing technicians, need a more accurate and efficient tool for air balancing.

• The Dwyer SMART Air Hood™ provides better:• Accuracy, mobility, efficiency, ease of balancing, and reporting

compared to other air flow hood’s currently on the market.

• Dwyer offers a differentiated technology, with the Quad Flow Design and the Predictive Balancing system.

• Proven Results: Saves Time and Money!
