The reduction of cooling power required by the electromechanical coolant pump, radiator fan(s), and thermal valve
demands real time control strategies.
Supplies hot-runner systems with a "thermal valve
gate"--i.e., using a separate, fast-acting tip heater to alternately freeze and melt the material at the tip.
This device acts as a one-way thermal valve
, if the temperature is hotter outside than in the refrigerator heat is not transferred into the refrigerator.
In automatic transmissions, temperature changes cause both the viscosity and density of the fluid to vary, making possible two thermal valve
The patent-pending "thermal valve
gate" is similar to the Seiki Spear system.
There will also be new examples of what one supplier calls "thermal valve
gates"--nozzles that have independent tip heaters that can quickly open up or freeze off the tip as needed.
Gate hot-runner probes, manifolds, and controls.
A compact "Universal Controller" that can run virtually any hot-runner system of any number of zones is new from Thermal Valve
Internally heated hot-runner probes employ patented Thermal Valve
Gating process, where by a separate second heater at the tip of probes cycles on and off, providing absolute control at the gate.
