SBS-4 and SBL-2D

The SB range of fluidised baths offers a safer alternative to the dangers associated with high temperature oil and salt baths.

These units are designed to be bench or floor standing and only require an electrical and air supply for operation. Air passes through the mass of the aluminium oxide (Alundum) particles via a porous plate in the base of the unit separating the individual particles and suspending them in free air, giving the properties of a liquid bath.

Heaters are fitted within the bath which allow temperatures of 500°C to 600°C to be maintained. Both models in the SB range feature a stainless-steel inner container insulated from the outer wall, a safety air pressure switch to protect against loss of air pressure and also a thermal cut-out.

It is highly recommended that the TC-9D temperature control unit is used in conjunction with these baths, greatly improving temperature stability and accuracy. See TC-9D link under "Further Information" on the left of this page.
Replacement Alundum (course, brown aluminium oxide) see "SB and BFS Accessories"
To replace alundum lost through normal operation and removal of items from the bath. Accept no other substitute as performance and functionality cannot be guaranteed with third party suppliers.
