RYDLYME by Apex Engineering Products — S.A. International — Authorized Distributor, Bangladesh
Dissolves 2.2 lbs of scale
per gallon. Safely.
RYDLYME is the world’s leading biodegradable descaler — NSF/ANSI/CAN 60 certified, recommended by the U.S. Navy, and used in thousands of facilities worldwide. It safely dissolves water scale, limescale, calcium, rust and struvite deposits without disassembling equipment.
How it works
Circulate. Dissolve.
Flush. Back online.
Scale is thermal insulation you didn’t order. A 1.5mm calcium deposit reduces boiler efficiency by 7%. RYDLYME is circulated through the waterside of the equipment — it dissolves mineral deposits into solution, which then drains away. No chiselling, no rodding, no hydro-blasting, no tube damage.
“Often imitated, never duplicated — 80+ years of proven descaling performance.”
- 01Assess & planEvaluate the scale buildup to determine the right RYDLYME dilution (25%–100%) and circulation method.
- 02Connect & circulateIsolate the waterside, connect a small pump and circulate RYDLYME through the equipment.
- 03DissolveRYDLYME dissolves scale, limescale, calcium, rust and struvite — without attacking the parent metal.
- 04Rinse & resumeFlush with water. Equipment returns to service the same shift.

Where RYDLYME works in Bangladesh.
Boilers & Steam Systems
Fire-tube and water-tube boilers in Bangladesh’s textile mills, food factories, pharmaceutical plants and industrial utilities — most jobs completed in one shift.
Heat Exchangers & Condensers
Shell-and-tube and plate heat exchangers in power stations, steel plants, fertilizer plants — restore full design heat transfer without pulling the bundle.
Chillers & Cooling Systems
Chiller condensers and cooling tower fill in garments factories, commercial buildings and industrial HVAC.
Pumps, Pipework & Valves
Scaled cooling water lines, pump casings, gate valves and strainers — dissolve blockages without pipe cutting.
Marine & Shipboard Equipment
Seawater-cooled engines, heat exchangers, sea chests and piping on vessels, dredgers and river craft.
Sugar & Food Processing
Evaporators, vacuum pans, crystallisers and process cooling systems in sugar mills and edible oil refineries.
Results
What RYDLYME dissolves — and what you get back.
Real equipment, real scale, real results. Each application below is a typical RYDLYME job — completed in hours, not days, with the equipment back online the same shift.
Boiler Tubes
Waterside calcium carbonate scale dissolved in-place — no tube pulling, no rodding, no hydro-blasting. Fire-tube and water-tube boilers returned to design efficiency in 4–8 hours.
Result: 7%+ fuel savings recoveredShell & Tube Heat Exchangers
Full tube-side descaling without pulling the bundle. RYDLYME circulated through the waterside dissolves scale into solution — flushed and back online in one shift.
Result: Design heat transfer restoredCooling Tower Basins
Scale and biofouling removed from basin, fill and spray nozzles — often with the cell kept running. Restores water flow and evaporative cooling capacity.
Result: Cooling capacity restored in hoursChiller Condensers
Scale on condenser tubes forces compressors to work harder — driving up kW per ton. RYDLYME restores tube cleanliness and drops energy consumption back to rated levels.
Result: Compressor energy cost reducedValves & Strainers
Heavy scale and struvite buildup dissolved from gate valves, check valves and strainers — restoring full bore and actuation without dismantling or replacement.
Result: Full flow restored, no parts replacedEvaporators & Vacuum Pans
Sugar mill evaporators and vacuum pans descaled before each crushing season — restoring heating surface and throughput capacity. NSF/ANSI 60 certified for food-contact equipment.
Result: Full season capacity recoveredBefore/after photography is available from Apex Engineering Products. Download from apexengineeringproducts.com or contact us for Bangladesh-specific job photos.
The RYDLYME family
One chemistry, multiple formats.
RYDLYME Industrial Descaler
The original biodegradable descaler. Dissolves water scale, limescale, calcium, rust and struvite from virtually any water-operated equipment. NSF/ANSI/CAN 60 certified. Compatible with copper, iron, steel, brass, rubber, plastic, ceramic, titanium and stainless steel.
Pack sizes: 1 Gal · 5 Gal · 30 Gal Drum · 55 Gal Drum · 330 Gal Tote
RYDLYME Marine
Specifically formulated for seawater-cooled systems — ship engines, heat exchangers, sea chests and pipework. Tackles the unique mineral composition of seawater scale (higher magnesium, barnacle deposits) that standard descalers struggle with.
Available on order for Bangladesh’s marine and shipyard sector
Industrial Descaling Systems
Purpose-built portable CIP systems designed to circulate RYDLYME through equipment. The 10CIP Industrial Descaling System is self-contained with pump, hoses, reservoir and flow controls — connect and clean without improvising.
Available: 10CIP · 20CIP · 30CIP · Custom
RYDALL Specialty Cleaners
Beyond descaling: RYDALL CC (coil cleaner for finned condensers and evaporators), RYDALL MP (multi-purpose biodegradable degreaser) and RYDALL HD (heavy-duty citrus-based degreaser) — a complete cleaning chemistry portfolio from Apex Engineering.
