Protects everything downstream of it.
Steel and polymer media filters, hydrocyclones, pre-engineered banks, and the control gear to run them — built for surface water, bore water, recycled water, and seawater pre-treatment.
The Cresoro filtration range.
Four core filter lines, plus the systems and control gear to run them.
CM30 — the one that does the heavy lifting.
When your water comes from a river, dam, reservoir, or recycled effluent, screens and discs clog inside a season. The CM30 pushes water through a deep bed of graded media — most particles never reach the outlet, and the ones that do are too small to matter.
Carbon steel, electrostatic powder-coated inside and out, robotically welded, pressure-tested. It handles the duty cycle that wears cheaper vessels through in two or three years.
| Model | Vessel Ø | Filtration area | Flow rate | Connection | Sand load | Weight |
|---|---|---|---|---|---|---|
| CM30-18 | 18″ | 0.16 m² | 15 m³/h | 2″ | 150 kg | 52 kg |
| CM30-24 | 24″ | 0.29 m² | 24 m³/h | 3″ | 250 kg | 82 kg |
| CM30-32 | 32″ | 0.52 m² | 45 m³/h | 3″ | 350 kg | 115 kg |
| CM30-36 | 36″ | 0.66 m² | 55 m³/h | 4″ | 400 kg | 140 kg |
| CM30-48 | 48″ | 1.17 m² | 80 m³/h | 4″ | 500 kg | 250 kg |
S235JR carbon steel, epoxy-polyester powder coat. 8 bar max, 60 °C max. SS304L / SS316L variants on request. Higher flow available with diffuser-type internals.
CM20 — first in line for bore water.
Sand kills emitters, scores pump seals, and wears nozzles to nothing. The CM20 spins it out before it reaches the rest of the system — no moving parts, no media to replace, no power needed.
Pair it upstream of a CM30 and you've got the full answer for bore water: heavy particles dropped first, fines polished second.
| Model | Connection | Flow rate | Max pressure | Weight |
|---|---|---|---|---|
| CM20-2 | 2″ | 25 m³/h | 8 bar | 25 kg |
| CM20-3 | 3″ | 50 m³/h | 8 bar | 28 kg |
| CM20-4 | 4″ | 70 m³/h | 8 bar | 30 kg |
| CM20-5 | 5″ | 120–140 m³/h | 8 bar | 65 kg |
| CM20-6 | 6″ | 160–200 m³/h | 8 bar | 92 kg |
Removes 98% of particles above 70 microns. Continuous flow, no stopping to clean.
CP30 — lighter install, no corrosion.
Not every job needs steel. For smaller flows, lower duty pressures, and corrosive water — saline groundwater, coastal landscaping, fertigation — polymer is the better answer.
Same media-bed filtration as the CM30, in a body that won't corrode, won't need recoating, and weighs a fraction as much. No crane, no specialised lifting gear, faster commissioning.
| Model | Vessel Ø | Connection | Flow rate | Sand load | Weight |
|---|---|---|---|---|---|
| CP30-20 | 24″ | 2″ (DN50) | 20 m³/h | 200 kg | 43.0 kg |
| CP30-25 | 24″ | 2½″ (DN65) | 25 m³/h | 200 kg | 43.2 kg |
| CP30-30 | 24″ | 3″ (DN80) | 30 m³/h | 200 kg | 43.5 kg |
PA6 glass-fibre-reinforced polymer, stainless wetted internals. 6 bar max, 60 °C max. For flows above 30 m³/h, run multi-vessel banks or step up to the CM30.
CP20 — same job, lighter package.
For smaller agricultural flows, or anywhere a metal body would corrode out — coastal pumps, saline bores, brackish recycled water.
Same centrifugal separation as the CM20, in a UV-stabilised polymer body. No coating to fail, no moving parts, no power.
| Model | Connection | Flow rate | Max pressure | Weight |
|---|---|---|---|---|
| CP20-10 | 1″ (DN25) | 5–10 m³/h | 6 bar | 1.9 kg |
| CP20-20 | 2″ (DN50) | 20–30 m³/h | 6 bar | 9.5 kg |
| CP20-25 | 2½″ (DN65) | 30–40 m³/h | 6 bar | 9.5 kg |
| CP20-30 | 3″ (DN80) | 40–60 m³/h | 6 bar | 19.0 kg |
Most projects need a bank, not a vessel.
Multi-vessel skids for high flow — shared inlet/outlet manifolds, sequenced backflush, one control panel running the lot. 2–8 vessels in any mix of CM30 or CP30, skid-mounted and pre-piped, with or without a hydrocyclone pre-stage.
Manual, semi-automatic, or fully automatic backflush, triggered by pressure differential, timer, or both.
Drives the bank automatically. Configurable timers, optional differential pressure trigger.
Backflush starts the moment pressure drop crosses your threshold. Hands-off operation.
Three things drive the decision.
Where your water comes from, how dirty it is, and what you're protecting downstream. Tell us those three and we'll point you at a starting line.
Pick your water source, what's in it, and the flow. We'll point you at the right line.
Or send us your water source, target filtration grade, and flow rate. We'll have a recommendation back inside 48 hours.
Every container is inspected before it's sealed.
We commission an independent third-party loading inspection at the factory — vessel counts, weld inspection, coating integrity, packing, and a documentation cross-check.
The report ships with your order. No surprises at the port.
Sell it under your brand. Or build it to spec.
Every vessel can ship in your RAL colour, with your branding and packaging, to the same corrosion standard as our standard finish.
When the catalogue doesn't fit the job, we build to spec — custom vessel sizes, 316 stainless for seawater, food-grade builds, AS 1210 / ASME / PED certification where required.
Engineering runs on project timelines: 6–12 weeks for design, longer for certified pressure vessels. Talk to us early.
Send your project. We'll size it for you.
