SML STC-9W2D dual-circuit water temperature controller - 2-zone mold temperature control

SML STC-9W2D industrial water temperature controller

A dual-zone, dual-circuit heating and cooling unit designed for precise and independent temperature control of two separate circuits in injection molds, blow molds, and components of plastics processing machinery.

Thanks to its 2-in-1 design, one compact unit replaces two conventional temperature controllers, saving space next to the machine and reducing investment costs.

Key product features:

Dual-zone 2-in-1 control: independent temperature setting and control for two separate circuits, such as the core and cavity sides of an injection mold.
Environmentally friendly medium - water: using water as the heat-transfer medium provides high thermal exchange efficiency and low operating costs. The maximum temperature is 120°C.
Microprocessor-based PID controller: separate displays and independent controllers for both zones ensure high process stability and repeatability.
High-performance circulation pumps: provide high flow rates and stable medium pressure in the heating and cooling channels.
Advanced safety system: the unit is equipped with water shortage sensors, overheating protection, pump overload alarms, and power phase monitoring.
Reliable construction: the internal system components and tank are made of stainless steel, providing protection against corrosion and scale buildup.
Mobile housing: durable lockable casters make it easy to move the unit between workstations.
