Fluidisation and Fluid Bed Heat Transfer Unit
Product Code : LSK-TWL-10811
Fluidisation and Fluid Bed Heat Transfer Unit (SKU LSK-TWL-10811) is an air-fluidised bed trainer for studying gas flow through fixed and fluidised beds and measuring heat transfer from a heated surface to the bed. A transparent glass chamber lets students watch the bed from the onset of fluidisation to entrainment. It suits chemical and mechanical engineering labs. Science Lab Supplies manufactures the unit at its factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and supplies it direct to colleges, tender contractors and distributors.
Specifications
The fluid bed heat transfer unit is specified in full in the table that follows. In short, air metered at 0.15 to 3.5 litres per second fluidises a bed in a transparent glass chamber with an electric heater, and a glass reinforced plastic panel carries the variable transformer, meters, digital thermometer and bed manometer.

Applications and Experiments for the Fluid Bed Heat Transfer Unit
The unit is used to compare packed and fluidised beds and to find heat transfer rates and coefficients, which are then compared with convective heat transfer in air. Students also investigate distributor design, depth of immersion, superficial velocity and particle size, topics shared by mechanical operations and heat transfer syllabuses.
- B.Tech/B.E. chemical engineering: pressure drop against air flow and minimum fluidisation velocity, set beside seepage through a fixed medium on the Permeability, Flow Nets And Darcy’s Law tank.
- Heat transfer coefficient between a heated surface and a fluidised bed.
- Effect of particle size, superficial velocity and depth of immersion, after flow meter practice on the Flow Meter Calibration apparatus.
- Project work with locally sourced bed materials and alternative air distributors.
Standard Scope of Supply
Each unit comprises the glass bed chamber with electric heater, air flow meters, variable transformer, volt and ammeter, digital thermometer, manometer and heater temperature controller on the glass reinforced plastic panel, together with the range of bed materials supplied. Alternative bed materials and distributors can be sourced locally.

Frequently Asked Questions
What can students measure on the fluidisation unit?
They can measure air flow and pressure drop through packed and fluidised beds, observe fluidisation up to entrainment, and find heat transfer rates and coefficients from the heated surface.
Can other bed materials be used?
Yes. A range of bed materials is supplied and can be changed quickly, and alternative locally sourced bed materials and air distributors can be used for student project work.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. The unit is built at its own factory in Saha, Ambala, India, and quotations come directly from the factory.
What safety features are fitted?
All components are fused and earthed and a heater temperature controller is fitted, while the volt and ammeter show the heater power input throughout each run.
