Figure 1: Components and controls – IFB-51 shown 

Item 

Description 

Function 

1 

Fluidised bath chamber 

Heated chamber containing the fluidised aluminium oxide. 

2 

Operating instructions 

Quick operating guide. 

3 

Eurotherm 3216 
temperature controller 

Used to set the required bath set point temperature. The 
control parameters have been factory pre-set. 

4 

Power indicator (green) 

Lights green when there is mains power to the unit. 

5 

Heater indicator (amber) 

Lights amber when the heaters are on. Will flash on and off 
when the bath is at set temperature. 

6 

Air flow table 

Indicates approximate air flow according to temperature. 

7 

Flow meter 

A float indicates the fluidisation air pressure set by the control 
valve. The flow rate indicated by the float in the tube is on a 
scale of 0.5 to 4.0 CFM (cubic feet per minute). 

8 

Air flow valve 

Controls the amount of air for fluidising the bed. 

9 

Fuses 

The unit is fitted with 2 x 25A (IFB-51) or 2 x 30A (IFB-52) fuses 

10 

Rating plate 

Details the model number, serial number and power rating. 

11 

Mains power cord 

Connect to mains power supply. 

12 

Compressed air inlet 

The air supply should be connected via suitable flexible hose.
