FAQ
Q1: What testing scenarios is this purifier mainly applied to?
A: The oil decolouration purifier regenerates used or degraded oils by removing color bodies, oxidation products, sludge, free carbon, and contaminants through adsorption (bleaching clay/activated clay, activated alumina, silica gel) and filtration. Used for transformer/insulating oil (restore dielectric strength, remove sludge/color from aged transformer oil - extends oil life, reduces disposal), lubricating/hydraulic oil (remove oxidation, varnish, color from industrial gear oil, hydraulic fluid, turbine oil), edible oil (bleaching of vegetable oils (palm, soybean, sunflower) to remove color (carotenoids, chlorophyll), oxidation products, soaps, residual phospholipids - food-grade), and industrial oil recycling (waste oil re-refining, cutting fluids, heat transfer oil). Process: oil heated (60-120 C) to reduce viscosity, mixed with adsorbent (or passed through adsorbent column), adsorbent removes color/oxidation via surface adsorption, then filtered to remove clay fines, optionally vacuum dehydrated to remove water/gas. Output: lighter color, reduced oxidation, improved clarity.
Q2: What standards does the purifier comply with?
A: Complies with ISO 17025 (if testing oil quality), ASTM D6871 (used insulating oil reclamation), ASTM D3487 (used mineral insulating oil), IEC 60422 (mineral insulating oil supervision), IEC 60296 (new insulating oil), GB/T standards for oil purifiers, and food-grade standards (FDA, EC 1935/2004) for edible oil contact parts. Hardware meets flow rate, filtration efficiency (particle removal per ISO 4406/NAS 1638), temperature control, pressure rating, and safety (overpressure, high temp, electrical). For transformer oil, verify output meets IEC 60296/ASTM D3487 specs (dielectric breakdown >50-70 kV, color <1.0, water <20-30 ppm, acidity <0.03 mg KOH/g). For edible oil, food-grade materials (316L stainless, food-grade seals), bleaching earth food-grade, and HACCP compliance.
Q3: What is the warranty period for the whole purifier and key components?
A: Whole purifier covered 12-24 months. Pump (wear - 3-7 years), filter elements/adsorbent (consumable - replace regularly), heating elements (wear - 2-7 years), seals/gaskets (wear - oil degrades), and vacuum pump (if included, wear - 3-7 years) are consumables/accessories. Damage from improper use, running dry (pump damage), over-temperature (oil degradation, fire), using incompatible oil (solvents, gasoline - explosion risk), poor maintenance (clogged filters cause overpressure), or unauthorized repair is excluded. Extended warranty and service contracts available. Pump/body 5-15 years; filters/adsorbent ongoing cost (main expense).
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained industrial/oil personnel. Workflow: connect oil inlet/outlet, preheat oil (60-120 C to reduce viscosity), prime pump, start circulation through adsorbent column/filter, monitor (pressure (clogged filter = high pressure - replace), color (visual or spectrophotometer), flow rate, temperature), sample and test (color, dielectric strength (transformer oil), acidity, water, particle count), change adsorbent/filters when saturated (color no longer improves, pressure rises), flush/clean after batch. Training 1-2 days provided. Safety: HOT OIL (60-120 C burns - use PPE, heat-resistant gloves), FIRE (oil is flammable, especially at high temp - no open flames, fire extinguisher (Class B), temperature control, do not exceed flash point), ELECTRICAL (high-power heater, proper grounding, lockout/tagout), PRESSURE (filter vessels pressurized - do not open while pressurized, relief valves), TOXIC (used transformer oil may contain PCBs (older oils - test before handling! PCBs are toxic/persistent; if >50 ppm, regulated as hazardous waste; wear PPE, dispose properly), edible oil vs industrial oil (do not cross-contaminate - dedicated units or thorough cleaning).
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibrate every 6-12 months: temperature controller (certified thermometer), pressure gauge (deadweight tester), flow meter, and oil test equipment (dielectric strength tester, colorimeter, Karl Fischer for water). Routine: monitor pressure (filter condition), temperature, and test output oil quality per batch (color, dielectric, acidity, water). Replace adsorbent/filters based on pressure differential or color breakthrough (not fixed schedule - depends on oil condition). For ISO 17025 oil testing lab, maintain calibration records for test instruments. For food-grade edible oil, verify food contact material compliance and cleaning validation.
Q7: Are supporting consumables universal?
A: Adsorbent (bleaching clay/activated clay, activated alumina, silica gel - universal from chemical suppliers but use correct grade (food-grade for edible oil)), filter elements (specific to housing size/micron rating - use OEM or compatible), pump seals/gaskets (specific), and oil test kits (universal). Long-term cost is dominated by adsorbent and filters (ongoing, depends on oil contamination level - heavily oxidized/sludgy oil consumes more clay). Heating element/pump replacement occasional.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes flow rate (small 10-50 L/min for lab/small transformers, large 100-1000+ L/min for industrial), process (adsorption only, adsorption + vacuum dehydration (removes water/gas), adsorption + filtration + degassing), adsorbent type (bleaching clay for color, activated alumina for acidity/polar compounds, silica gel for water/color, molecular sieve), construction (carbon steel (industrial) or 316L stainless (food-grade/pharma)), automation (PLC/HMI, auto filter change indication, data logging, remote monitoring), safety (explosion-proof (ATEX for flammable/solvent), overpressure/temp protection, emergency stop), features (heater, oil quality sensors (color, dielectric, particle), pre-filtration, post-filtration (polishing)). Accessories: spare filters, adsorbent (food/industrial grade), oil test kit (dielectric, color, water), pump seals, sample bottles, certifications (CE, ISO 9001, IEC 61010, food-grade, ATEX).
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes purifier, pump, filters (initial), controls, manual (adsorbent and spare filters often separate). On-site installation, commissioning, and training typically included or recommended (electrical connection, hose setup, first batch run with actual oil, parameter optimization, user training; manufacturer/certified technician standard for industrial equipment). Always test output oil quality before full production. For food-grade, verify cleaning and food contact compliance.
Q10: What types of oils are compatible with this equipment?
A: Compatible: transformer/mineral insulating oil (aged, sludge, color), lubricating/hydraulic/turbine oil (oxidation, varnish), edible oils (palm, soybean, sunflower, coconut - bleaching, food-grade unit), heat transfer oil, and industrial mineral oils. Not compatible: gasoline/diesel/solvents (flammable, explosion risk - use explosion-proof unit or avoid), PCB-contaminated oil without proper handling (test first; >50 ppm PCB = hazardous, regulated), used motor oil with high fuel dilution/soot (may need pre-treatment, different process), synthetic oils (may interact with adsorbent - test compatibility), water-contaminated oil without vacuum dehydration option (water reduces adsorption efficiency - use vacuum model), or oils with additives that adsorbent may remove (some anti-wear/antioxidant additives can be removed by clay - monitor additive content after treatment). For edible oil: use food-grade unit and food-grade bleaching earth; do not use industrial unit for food (cross-contamination).
