Circulating Oil ISO VG 220

Description

1. Product Overview
Circulating Oil ISO VG 220 is a high-performance lubricant formulated from severely hydrotreated base oils and a balanced additive package, including antioxidants, rust inhibitors, and anti-wear agents. It is primarily used in industrial recirculating oil systems such as steam turbine bearing housings, hydraulic presses, rolling mill bearings, and large enclosed gear drives. The key value proposition lies in its exceptional oxidation stability and rapid water separation, which prolongs oil change intervals and protects capital equipment. Strategically, adopting this grade reduces maintenance-led procurement frequency and mitigates the risk of catastrophic bearing failure in 24/7 operations.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Severely hydrotreated Group II base oil (≥85%) + phenolic & amine antioxidant blend + zinc-free anti-wear additive + corrosion inhibitor + anti-foam agent

• Purity Level: ISO 4406 cleanliness code 18/16/13 (standard); Premium 16/14/11 available upon request

• Physical Characteristics: Amber liquid; ISO Viscosity Grade 220 (cSt @40°C: 198–242); Viscosity Index ≥95; Density @15°C: 0.88–0.90 g/cm³; Pour point ≤ -9°C

• Packaging Options: 208L steel drum, 1,000L IBC tote, bulk ISO tank, 20MT flexibag

• Shelf Life: 36 months in sealed original container under dry, non-freezing storage

3. Core Industrial Applications

• Primary Industries: Steel & aluminum rolling, pulp & paper, power generation (hydro/steam turbines), mining conveyors, cement manufacturing

• Specific Use Cases: Circulating systems for large journal bearings, low-speed enclosed gearboxes, plain bearings in compressors, vacuum pumps, and oil-lubricated rolling mill backup rolls

• Performance Advantage: Superior demulsibility (typically achieves <10 min water separation vs. >30 min for commodity oils) minimizes sludge formation; high filterability extends cartridge life by 20–25%; cost advantage from reduced disposal frequency and lower replenishment volume

4. Competitive Advantages

• Quality consistency: ISO 9001:2015 certified production with batch-level GC-MS tracking; product to product viscosity variation ≤2%

• Supply reliability: Three-region buffer stock (Americas, EMEA, APAC) guaranteeing 98.5% same-day dispatch on standard packaging

• Logistics capability: Bulk tanker loading at 20MT/hour; export-ready drum pallets (80 drums per 40ft HC container)

• Price competitiveness: Direct-from-refinery pricing model eliminating 2–3 distribution layers; contracted spot pricing available for >100MT/month

• Sustainability: Low-chlorine formulation (<10 ppm); meets EPA 2013 VGP requirements for environmentally acceptable lubricants (EALs) for incidental contact

• Technical support: Full TDS, SDS, and compatibility letters; tribology lab access for used oil analysis ROI modeling

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): BULK 20MT (one ISO tank)

• Loading capacity (MT per container): 18–20 MT per 20ft standard dry container (80 x 208L drums = 18.4 MT net); 20 MT per 20ft bulk flexibag; 24 MT per 40ft HC palletized drums (not recommended for heavy weight limits – use 20ft for drums)
