DN1 is the bottom outlet of the spherical vessel.
C is the PCD of the three support points.
Heating mantles provide a positive alternative to steam heating using boilers or immersion heaters. They run at black heat, transferring the heat to the liquid partly by radiation and partly by convection.
The heating elements are closely pitched in a sinusoidal pattern to give an even distribution of heat and to avoid hot spots. This results in a thermal efficiency exceeding 80%.
Precise control of heat input is provided by a system of energy regulators and switches built into the heating mantle circuitry. All heating mantles are fitted with safety cutout thermostats in order to prevent overheating of the glass vessel.
Type VSL spherical vessels – vessels with sealed-in valve seat for BAL bottom outlet valves are ideal for use with these units.
