BROLERN Bronze Filter Cartridges - the product family this guide covers
Core points
- The purchase price is one component of the real cost: TCO adds service life, cleaning and regeneration, change-out labour, downtime and disposal [TCO procurement framework].
- The classic comparison: a cartridge twice the price that lasts three times as long is the cheaper one - the same logic applies to cleanable versus disposable media [TCO procurement framework].
- Cleanable media (sintered bronze, stainless, PE/PP) converts replacement cost into regeneration cost - backwash and ultrasonic cycles are typically far cheaper per run than a new element.
- Disposable depth media (melt-blown, wound) wins on unit price and shines in staged trains where each stage is cheap to replace.
- Certifications add cost - public procurement notes put validated performance at a 15-30% premium - but on regulated lines that premium is not optional [TCO procurement framework].
The TCO comparison table
| Unit price | What the quotation shows - and almost the only thing buyers compare |
|---|---|
| Service life | Months in your medium at your flow - the biggest TCO lever |
| Regeneration | Cleanable media: backwash/ultrasonic cost per cycle vs a new element |
| Change-out labour | Minutes per element, multiplied by frequency and locations |
| Downtime | Production lost during change-outs on critical lines |
| Disposal | Spent disposable elements - a real cost on hazardous-duty lines |
| Certification | Validated/document-rated media carry a premium - mandatory on regulated lines |
Worked comparison: cleanable sintered vs disposable depth
Take a duty that consumes one disposable melt-blown element per month. A sintered bronze or stainless element in the same housing costs several times more up front - but survives many cleaning cycles across years of service. Public industry comparisons draw the same conclusion: bronze costs less initially while stainless costs less over time, and in both cases the cleanable family competes on TCO, not on unit price [TCO procurement framework]. The honest way to decide is to log three numbers for one year: elements consumed, cleaning labour, and downtime - then let the data pick the family.
FAQ
Why is unit price misleading?
Because service life differs - cost per year of clean flow is the comparable number, not cost per element.
Cleanable or disposable?
Cleanable (sintered metal/plastic) where fouling is washable and duty is continuous; disposable depth media where loads are light and economy rules.
What else belongs in TCO?
Labour, downtime, disposal - and the certification premium on regulated lines [TCO procurement framework].
Conclusion
Compare cartridges the way your accountant compares machines: over years, including labour and downtime. BROLERN manufactures both cleanable sintered media and economical depth media - and will run the TCO comparison for your duty before you order.
FAQ
Why is the unit price misleading?
A cartridge half the price but replaced three times as often costs more per year - TCO adds service life, labour, downtime and disposal to the comparison.
How do cleanable media change the math?
Sintered bronze, stainless and plastic media survive many cleaning cycles - regeneration cost per cycle is typically far below a new disposable cartridge.
What else belongs in TCO?
Change-out labour, system downtime, disposal of spent elements, and the documentation or certification the duty requires.
