SPIRAX

We have been developing and producing plastic
ring packing, “SPIRAX” for more than 40 years
as a pioneer of plastic fillers inJapan. SPIRAX
has been used in absorption towers in a variety
of industrial applications, and we have built our
expertise in watertreatments with many
achievements in water supply and sewerage
systems represented by deaeration and
deodorization towers. Based on the expertise
we have acquired through developments and
productions, we are expanding our engineering
services to our customers for designing more
effective towers. We provide a vast array of
models, sizes and materials to meet individual
service conditions of our customers.

Absorption and adsorption technology
Concentration, acid, distillation technology

Features

・Large usable area with no dead surface area (surface not exposed to liquids)
・Low pressure loss with line structure that allows high void rate and decreasing tower diameter
・High liquid dispersion efficiency with curved line structure and many contact points in packing layers
・Lightweight, strong chemical and mechanical properties with synthetic resin
・Ease of filling and extraction using lightweight material
・Ease of removing adhesions

Petrochemical ／ Steel,Metal,Paper,Inorganic Chemical ／ Medical,Food,Biochemical ／ Industrial Waste Treatment

Major Applications

Plastic tower packing for deaeration and deodorization towers of water supply and wastewater treatment plants
Plastic ring packing for absorption, diffusion and distillation towers
