Berl Saddle
Product Name:
Berl Saddle
Model:
12
Description:
Berl saddle is an opening packing shaped like a saddle without inside and outside, the berl saddle performs better as compared to Raschig rings in the aspects of even fluid distribution and low resistance. And it makes lower pressure against the inner wall of the tower than the ring packing.
Inert Alumina Ceramic Ball
Product Name:
Inert Alumina Ceramic Ball
Model:
12
Description:
Inert alumina ceramic ball is widely used in many fields, such as petroleum, chemical engineering, fertilizer, environmental industry, etc. Being the covering and supporting material and tower packing for catalyst in the reactor, the ceramic ball has features of high intensity, high chemical stability and thermal stability.
Perforated Ceramic Ball
Product Name:
Perforated Ceramic Ball
Model:
12
Description:
Perforated ceramic ball is developed on the basis of inert ceramic ball. It has an adequate mechanical strength, good chemical and thermal stability as the normal inert ceramic ball, further more, it has larger surface area and free void which directly make the dispersion and flux of the fluids increased, and bring down the resistance of the system resulting from the perforated holes.
