Protects the nozzle and shell from overheating
Proven in Claus Thermal Reactor service for
over 25 years
Prevents sulfur from building up in the reactor entrance nozzle
Secures and mechanically isolates both ceramic protective wells
Resilient, allows movement between the nozzle supported HTP and the refractory
Everything needed is in one package,
ready to be installed at the job site
Eliminates inefficiency, guesswork, short cuts,
and possible errors at the jobsite.

Application

The insulation must protect the nozzle and shell from over heating. The correct type of nozzle insulation must be used with an Delta Controls HTP Thermocouple. The insulation must tightly fill the space between the two wells and the nozzle flange/wall. It must be resilient to allow movement between the shell and the refractory liner. It must be accurately cut and the components installed in the correct sequence to prevent protective well damage.

Over 30 Years of experience has taught Delta Controls the best combination of materials to use. All of the needed insulation, of the correct sizes and types, together with an illustrated installation instruction drawing are furnished in a single weatherproof package. This ready to use kit is made up for a specific nozzle size and height. It is also tagged with the model, size, and jobsite identification numbers. This kit method has proven to be economical, convenient, and helpful in insuring good results.
