As a professional thermal conductive oil heater, it leverages advanced PID control technology and indirect cooling systems to maintain oil temperatures within a range of inlet water temperature +45℃ to 180℃—ideal for industries requiring consistent heat transfer. Compatible with a 3-phase 380/400V 50Hz power supply (3phase+Earth), this unit is designed for reliability, efficiency, and safety, making it a top choice for plastic molding, chemical processing, pharmaceutical production, and more. Whether you need a compact model for small workshops or a high-capacity system for large-scale equipment, the AOS series (AOS-05(A), AOS-10(A), AOS-20, AOS-30) offers customizable options to meet your specific needs.
At the core of our Standard Oil Temperature Control Unit is its exceptional temperature control accuracy: ±1℃ via PID regulation. This level of precision ensures consistent process stability, reducing product defects and optimizing workflow efficiency. Unlike standard heaters, our unit maintains tight temperature tolerances even in dynamic industrial environments, making it perfect for applications where thermal consistency is non-negotiable—such as injection molding or chemical reaction kettles.
Safety is paramount in industrial settings, which is why our unit is equipped with a 4-in-1 alarm system covering pump reversal, oil shortage, overload, and abnormal heating. These real-time alerts prevent equipment damage, minimize downtime, and protect operators, aligning with global industrial safety standards. The oil shortage alarm, in particular, safeguards the circulation pump and heating element from dry running—extending the unit’s service life.
Featuring an indirect cooling system, the unit eliminates direct contact between cooling water and thermal conductive oil, ensuring clean, contamination-free heat transfer. Paired with high-efficiency circulation pumps (flow rates ranging from 22 L/min to 150 L/min, pump heads from 13m to 20m), it delivers rapid heat distribution and uniform temperature across your equipment. This design not only boosts energy efficiency but also reduces operational costs compared to conventional heating systems.
The AOS series offers four tailored models to suit diverse industrial needs:
AOS-05(A): 6kW heating capacity, 0.37kW motor power (compact for small-scale machines)
AOS-10(A): 9kW heating capacity, 0.75kW motor power (dual pump flow options: 85/30 L/min)
AOS-20: 12kW heating capacity, 1.5kW motor power (ideal for mid-sized equipment)
AOS-30: 12kW heating capacity, 2.2kW motor power (high-flow, high-head for large systems)
