Airflow Control Within Close Tolerances Saves Money

Airflow Control Within Close Tolerances Saves Money

In drying and coating processes in the pharmaceutical, food and beverage, chemical, petrochemical, and mining sectors, millions of dollars are lost daily - in fluidized beds, rotary drums, flash dryers, kilns, and similar processes. Because of improper air and product feeds, these devices' failure can cause validation problems, causing downtime, re-validation, and loss of both goods and profits. It's vital to control airflow through these devices.


How can vital processes and devices that need to work within tight tolerances over a broad operating range be supported with continuous air mass flow at a regulated air temperature?

1) Improving Production Efficiency

The off-specification product must be recycled or wasted. This process is too costly, especially in the validated industries. Precise control of airflow and air temperature is essential to maintain high product quality, reduce waste, and increase uptime.  The performance of many processes would benefit from measuring the mass flow of process air.  Also, limited flow meter turndown often constrains operational flexibility - primarily when requirements cover a wide range of operating conditions.  

2) Dealing with Limited Straight Pipe Runs

Airflow meters incorporated into process equipment are often inaccurate due to the short upstream and downstream straight pipe run.  The installation of a good straight run can quickly become problematic in tight quarters, so other solutions are needed.

3) Reducing Plugging and Coating

Most process equipment designs do not include relatively dirty exhaust flow measurements, even though they can provide significant operational benefits. They are often not included because exhaust flow meters can become coated and plugged when particulates are present — reducing flow meter accuracy.  

Products from Air Monitor solve these issues by enhancing the reliability of your airflow meters by improving their accuracy over a wide range of flow rates, thus improving the process's efficiency, improving the product's consistency, and increasing production rates to reduce fuel spending.
