The Blince OR DT Type Heat Exchange Copper Tube Hydraulic Oil Cooler is a high-performance solution designed to maintain optimal oil temperatures in plastic machinery, ideal for injection molding, extrusion, and blow molding systems. Engineered with copper tube technology, this cooler ensures efficient heat dissipation while resisting corrosion from hydraulic fluids.
Superior Heat Transfer:
Copper tube bundle (15-30 tubes) with aluminum fins (2.5mm pitch), achieving heat dissipation up to 50 kW (ΔT 20°C), reducing oil temperature by 15-20°C in continuous operation.
Counter-flow design (oil/water) for 95% heat transfer efficiency, minimizing water consumption (5-15 L/min flow rate).
Durable Construction:
Stainless steel 304 housing (ISO 20143) and copper-nickel tubes (CuNi 90/10), resisting corrosion from water-based coolants (pH 6-8) and hydraulic oils (NAS 1638 Class 10).
Removable end caps for easy tube bundle cleaning, reducing maintenance time by 50% compared to brazed coolers.
System Compatibility:
Supports oil flow rates 20-200 L/min and water pressures up to 10 bar, compatible with plastic machine brands (Haitian, Demag, Arburg).
NPT/BSPP thread options and flange connections (ISO 7005-1), simplifying integration into existing hydraulic circuits.
Safety & Compliance:
Pressure test rating: 1.5x working pressure (oil side: 300 bar, water side: 16 bar), compliant with ASME BPVC Section VIII Div. 1.
Thermostatic valve option (50-60°C activation), automatically regulating coolant flow to maintain optimal oil viscosity (30-50 cSt).
Ideal for plastic machinery, this cooler excels in:
Injection Molding Machines: Controls oil temperature in hydraulic systems of 100-5000 ton machines, preventing viscosity changes that affect mold clamping force.
Extrusion Lines: Maintains consistent oil viscosity for gear pumps and screw drives in PVC/PE pipe production, improving product quality (wall thickness variation ≤1%).
Blow Molding Equipment: Prevents overheating in high-speed blow molding machines (cycle times ≤10 seconds), ensuring stable pressure for bottle formation.
Industrial Hydraulics: Used in die-casting machines and metalworking tools, with optional anti-corrosion coatings for seawater-cooled systems.
Q: What is the recommended coolant type?
A: Deionized water or ethylene glycol mixture (max 50%), with conductivity ≤5 μS/cm to prevent electrolytic corrosion.
Q: Can it be used with synthetic hydraulic oils?
A: Yes, compatible with all mineral oils, synthetic esters, and polyglycols (ISO VG 22-100).
Q: How often should the tubes be cleaned?
A: Quarterly visual inspection; chemical cleaning recommended when pressure drop increases by 30% (use mild alkaline solution, pH 9-11).
