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.
