Safer alternative to high temperature oil and salt baths
Requires 20 lb (9 kg) of brown sand (01184-63)
More About this Item
Use these fluidized sand baths for your heat treating processes, temperature sensor calibrations, and electrical component testing. Baths use aluminum oxide fluidized by low-pressure air as a dry bath medium with excellent heat transfer properties. Inert, nonflammable aluminum oxide is safer to use than oil and will not corrode your sample vessels or produce toxic fumes. Vessels of all shapes can be easily immersed and safely removed from the bath, without the hazard and mess of hot oils. Make temperature adjustments via a control knob and reference dial. Baths require a dry air flow of approximately 3 cu ft/minute for model 01184-00 and -02 and 5 cu ft/minute for 01184-04 at about 3 psi pressure; order an air pump separately. All baths have a thermowell and an overspill flange. Note: not recommended for shape setting in laboratory research device manufacturing or for heating of reactors.
Nice easy to use system, but there is not enough sand to fill the bath to the level of our liking. If you're going to pay several thousand dollars for the system, it should include enough sand to overfill the bath. Called tech support, but there is no recommendation to buy the sand.
What are the heating up time from 20 C to 200 C for SN-01189-50 and SN-01184-02 sand baths?
We have only specified the heat-up time from ambient to 350C (50 mins) and from ambient to 600C (70 mins) for the 01189-50. The heat-up time from ambient to 200C for the 01184-02 is 6 mins.
The heatup time to 200°C is approximately 30 minutes.
Is the top of the cylinder open? I need to heat a quartz tube while it is connected to a manifold, and therefore the heating system must be open on the top so the tube can be partially submerged in the sand.
The cylinder is open at the top, and the bath comes with the overspill flange accessory. That way you can fill the sand to the top without making a mess. You can purchase additional sand under part numbers 00152IM or 00257US.
is the temperature controller required ?
does the bath dial just read one to ten so that one must calibrate the dial with a thermocouple of some kind ?
Yes, for a complete system the bath, controller, and air pump must be purchased. The temperature controller uses a Type K thermocouple as to adjust and control temperature precisely. Yes, the sand bath just has an analog dial to adjust the temperature.
