Features
Designed to study of flow through fixed and fluidized beds of solid particles..
Separate columns for Air & Water.
Comprehensive Instrumentation Panel with all necessary measuring instruments & Safety Devices.

Tesca Fixed & fluidized Bed Apparatus 32061 is designed for the study of water and air flow through fixed and fluidized beds of solid particles and the observation of the difference between aggregative and particulate fluidization. The apparatus consists of two transparent test tanks for air and water. Two manometers are provided for measurement of bed pressure drop in the tanks. Water is circulated from a storage tank through a control valve and variable area flow meter to the appropriate test tank by a diaphragm pump. An overflow returns the water to the sump tank. Air supply to the second column is by diaphragm compressor through a control valve and variable area flow meter. Air is discharged to atmosphere. Detailed Operation & Maintenance Manual is provided along with the trainer.
