Metal you can filter through. Made here, not imported.
Clarysynt sintered porous metal handles what polymers cannot: up to 900 C depending on alloy, aggressive solvents, pyrophoric catalysts, years of backwash cycles. Gopani makes Clarysynt media in its own Ahmedabad plant, and that fact changes the economics of every system built on it.
From process to proof, the way we evaluate every duty.
| Customer process | Critical problem | Engineering solution | Evidence to demand |
|---|---|---|---|
| API hydrogenation | Precious catalyst lost with every batch | Clarysynt candle filtration with closed-circuit backwash | Recovery rate, batch count per element, cleaning protocol |
| Culinary and process steam | Particulate carryover into product contact | Sintered elements rated for continuous steam duty | Retention rating at temperature, service history |
| Fermentation and beverage carbonation | Inconsistent bubble size, contamination risk | Spargers and carbonation stones with controlled pore structure | Pore uniformity data, CIP compatibility |
| Hot gas and polymer filtration | Polymer and fabric media fail at temperature | Alloy-matched sintered elements to 900 C (alloy dependent) | Alloy certification, pressure-temperature envelope |
Where polymer media stops working
Polymer and fabric media soften, swell or break down at high temperature, in aggressive solvents and under repeated cleaning, and they cannot be backwashed hundreds of times. Where they are forced into that duty, the plant pays in change-outs, contamination risk and lost catalyst. Where the answer is a sintered element that has to be imported, every replacement carries import cost, lead time and a single point of supply inside a critical process.
Four media, four jobs
| Media | Construction | Where it fits |
|---|---|---|
| Clarysynt Sintered | Metal powder isostatically compacted and heat treated into porous layers; a tortuous path through the wall | Fine retention with high mechanical strength; the catalyst recovery and hot-gas element |
| Clarysynt Multi-layered Mesh | Several layers of wire mesh bonded together | Lower ratings than a single mesh can reach, with backwashable wire-mesh construction |
| Clarysynt Random Fibre | Randomly laid metal fibres, sinter-bonded into a thick, high-porosity medium | Gels and agglomerates: a surface filter that also works in depth |
| Clarysynt Mesh | Woven wire mesh, cylindrical or pleated | Higher temperature and higher flow at low differential pressure than polymeric pleated elements |

Sintered metal filtration: direct answers
Why does in-house sintered media manufacturing matter?
Where sintered media is imported, each replacement carries import cost, import lead time, and a single point of supply risk inside your critical process. Gopani manufactures Clarysynt media in Ahmedabad, so replacement elements, custom geometries, and engineering answers come from one plant, in days.
What alloys and ratings are available?
Standard elements in SS 316L and SS 304, with Hastelloy C-276, Inconel 600, Monel 400, Titanium, and Zirconium for aggressive chemistry. Filtration ratings from 0.5 to 25 micron with custom ratings on request, and service temperatures from cryogenic (minus 150 C) up to 900 C depending on alloy.
How long do sintered elements last?
Sintered metal is a regenerable technology: elements clean in place by reverse-flow gas or liquid backwash and return to service. In continuous catalyst recovery duty, element life of 5 to 10+ years or 5,000+ batches is the design basis, which is where the total cost of ownership argument against disposable media is won.
What product forms does Clarysynt come in?
Filter cartridges and candles, ultrafine porous tubes, spargers and carbonation stones for gas-liquid contact, sintered discs, and engineered elements for HPLC and pneumatic components. If your geometry is not standard, we sinter to drawing.
Which Clarysynt media type do I need?
Sintered powder for fine retention and strength in catalyst recovery and hot gas. Multi-layered mesh where a wire-mesh element must reach a lower rating. Random fibre for gels and agglomerates. Woven mesh, cylindrical or pleated, for higher flow at low differential pressure. Send the duty and we recommend the media and alloy.
What pressures do Clarysynt cartridges take?
The element data gives a maximum forward operating pressure of 15 to 25 bar and a maximum reverse differential pressure of 3 to 9 bar, depending on media and construction. Housings are built to ASME Section VIII, PED or IBR as the application needs.
What are spargers and carbonation stones used for?
Introducing nitrogen, oxygen or carbon dioxide into a liquid as fine, even bubbles, which raises gas absorption against drilled pipes and similar spargers. They serve fermentation, bioreactors, beverage carbonation and foam generation, and are regenerated by cleaning.
What we need from you for a firm recommendation
- Process fluid or gas, temperature and pressure, including upsets
- The particle or catalyst to retain, with its size distribution if known
- Chemistry the alloy must survive, and the cleaning or backwash method
- Flow rate and duty cycle: batches per day or continuous hours
- Housing code your site requires: ASME, PED or IBR
Why in-house media changes the economics.
A system built on imported sintered elements inherits the import's cost, lead time, and replacement dependency. Clarysynt media is powder-pressed and sintered in our own plant, and each element is tested in our laboratory for pore uniformity and mechanical strength. When an element needs replacing at 2 am before a batch, the answer is in Ahmedabad, not in a customs queue.
