Temperature Control Unit : Water
Model: SK-2475-HE
- Water temperature control units circulate temperature stabilized water through the process for process temperature control.
- The temperature control range of this unit is 32°F - 250°F.
- A pump circulates water through the process. A heater and a cooling valve work together to control the water temperature.
- This temperature control unit requires a plant water supply source.
- Advantage temperature control units are portable, built on casters to easily move the unit between processes.
- Units are available with a variety of different control instruments, heater sizes, cooling valves and physical packages.
