01
Published hot-service range
The existing product page states 180–250 °C for compatible liquids and chemicals.
Hot-process filtration
High-Temperature Filter Pads
Heat-resistant depth media for particulate removal from hot cooking oils and other compatible liquids, with a published product-family range of 180–250 °C.
Operating principle
How the filtration product works
High-temperature filter pads provide a porous depth medium for removing particulate matter from hot, compatible liquids. In frying-oil service, circulation through supported media retains suspended crumbs and degradation solids that would otherwise remain in the oil.
Sri Bharathi publishes an operating-temperature range of 180–250 °C for this product family. That range does not replace confirmation of the precise grade, support arrangement, exposure time, pressure and fluid chemistry for each installation.
Media design
Construction and process behaviour
The current Sri Bharathi source describes these as technically advanced, heat-resistant depth-filtration media in various dimensions. It does not publish the exact fibre or binder formulation. That construction should therefore be confirmed on the quotation and grade documentation rather than inferred from standard cellulose pads.
At elevated temperature, dimensional stability, seal integrity, oxidation, pressure drop and safe handling become as important as particle retention. The filter assembly, piping, pump, valves and operator procedure must all be rated for the process.
What to evaluate
Important features and benefits
02
Depth particulate removal
A porous structure captures suspended material through the media thickness.
03
Cooking-oil duty
The product is specifically referenced for filtration of oil used in frying processes.
04
Multiple dimensions
Various sizes are available, subject to equipment and support review.
05
Process quality support
Removing suspended fatty or food residues can support oil-management procedures.
06
Application confirmation
Grade-specific composition and limits should be approved before hot operation.
Technical data
Specification and enquiry checklist
Values below are limited to information published by Sri Bharathi. Final grade, compatibility and operating limits must be confirmed against the actual process.
| Selection parameter | Available / verified information | Engineering relevance |
|---|---|---|
| Published temperature range | 180–250 °C. | Confirm continuous versus intermittent exposure and actual grade limit. |
| Duty | Hot edible cooking oils and other compatible liquids/chemicals. | Fluid compatibility must be verified; the range is not universal permission. |
| Filtration mode | Depth filtration. | Supports solids capture within the medium and at the developing cake. |
| Dimensions | Various; provide equipment drawing or pad sample. | Correct support and sealing are critical at elevated temperature. |
| Material composition | Not stated on the public source page. | Request a grade-specific technical data sheet before approval. |
| Change-out | Based on pressure/flow, clarity and safe operating procedure. | Hot-media handling requires a controlled cool-down and disposal method. |
Process fit
Applications and selection considerations
The published primary application is particulate removal from hot cooking oils used in frying, including hotels, restaurants and the wider food industry. Other hot liquids or chemicals require an explicit compatibility review because temperature resistance alone does not establish chemical suitability.
Safety and selection considerations
- Maximum and normal fluid temperature, including start-up excursions
- Fluid flash point and applicable plant safety controls
- Housing and support-plate temperature and pressure rating
- Oil viscosity at the actual filtration temperature
- Solids type, concentration and required circulation rate
- Cool-down, drainage, change-out and disposal method
Questions engineers ask
Frequently asked questions
Can a standard cellulose pad be used at 200 °C?
Do not assume so. Use only a grade whose supplier has confirmed the construction and limit for the intended exposure.
Is 250 °C suitable for every liquid?
No. It is the published product-family range. Chemical compatibility, pressure, exposure duration, supports and safety controls remain application-specific.
What determines the change-out point in fryer-oil filtration?
Track flow or pressure together with visible solids, oil-quality indicators and the site operating procedure. Avoid relying on appearance alone.
Are these pads food grade?
The legacy page describes them as food-grade safe, but customers should request current, grade-specific food-contact documentation for their jurisdiction and use.
