“Large Flow” Water Heaters STM-2430WF
Features
Product Technology
• P.I.D. multi-stage temperature control system can reach a stable mould temperature within the accuracy of 0.5℃.
• Equipped with functions of automatic exhausting and water supply.
• Adopts large-flow pump with high stability, which especially suitable for extrusion molding and applications alike.
• Direct cooling can rapidly cool down moulds to the set point with cooling capacity up to 350kW.
Safety Performance
• Multiple safety devices including power reverse phase protection, pump overload protection, overheat protection and low level protection that can automatically detect abnormal operations and indicate this via visible alarm.
• Advanced design of return circuit can avoid high pressure explosion when system under faults.
Key Improvements
• Cooling capacity was raised up from 40kW to more than 300kW.
• Based on low pressure protection, electronic high pressure protection was added to achieve dual-protection for high pressure switch and safety valve.
Performance-price Ratio
Before improvement, devices are not suitable for extruders that require large cooling capacities. The improved STM-2430WF is not only suitable for heating up moulds and maintaining temperature but applied to more applications.
Application
STM-WF series Large Flow” are suitable for heating up moulds and maintain their temperature, although they can be used in other applications like extrusion.
