FAQ

1. What’s the delivery time ?

A: About 4 weeks for regular alumina blocks. (43 cells ,150*150*300mm) for 20 GP container.

2. How doesAlumina block work in RTOs Equipment ?

A : It let the straight-through flow prevents dust build-up and damage from aggressive chemicals ,also bring out maximum heat recovery and low pressure loss .

3. Why different shapes of cell ?

A : It differs from heat efficiency Conductivity through the Honeycomb ceramic passage .

4. What is the RTOs ?

A : Regenerative Thermal Oxidizer (RTO) is an industrial system that destroys volatile organic compounds (VOC’s) in process exhaust air before it pollutes the environment.

5.  Causes of ceramic block damage.

A : Impact , thermal shock damage , rapid steam vapor explosion,

6. How does monolith blocks work in RTOs ?

A: the Alumina blocks store the heat generated by the decomposition of VOCs, and uses the thermal energy stored in the alumina blocks to pre-heat and decompose the untreated VOCs, thereby achieving high thermal efficiency.
