Operating Modes
The WHU has three basic modes of operation.  These modes are with respect to how the 3-way valves function at specific times during operation.  These 3-way valves rotate to deliver either warm or cold water to a specific bank of valves depending on control requirements.  There are four 3-way valves in this unit.  They make up two zones of supply water delivery for the two main valve banks.  The first bank is for Valves 1-5, the second for Valves 6-10.

 

WHU Mode 1
This mode depicts that both the Stationary and the Movable side of the tool requires heat to reach processing temperatures or to maintain them.  Notice heated water is being pumped through electric heating elements, out through 3-way valves, out StackValves, through Mold, out of mold back into StackFlow Returns, and back through the pump.  When in heating Mode 1, all StackValves are open to allow all zones to be preheated to the desired temperature.  It is in a continuous flow circulation mode.

WHU Mode 2

This mode depicts that both the Stationary and the Movable side of the tool has reached processing temperature and will require cooling to maintain it.  Notice chilled water enters Chiller Supply and goes through 3-way valves directly out to theValve banks.  When in cooling Mode 2, all Valves work like normal Pulsed Cooling, whereas, chilled water will be supplied to individual zones as determined by the sensors in the steel to maintain the desired mold temperature.  When in this mode for at least four minutes, the pump and heating elements will turn off to save energy.

WHU Mode 3

This mode depicts that the Stationary has not reach processing temperature or requires heat to maintain it and the Movable side of the tool has reached processing temperature and will require cooling to maintain it. On the Stationary side, notice heated water is being pumped through electric heating elements, out through 3-way valve, out StackValves, through Mold, out of mold back into StackFlow Returns, and back through the pump.  Notice on the Movable side, chilled water enters Chiller Supply and goes through 3-way valve directly out to the Valve bank.  On the Movable side, all Valves work like normal Pulsed Cooling, whereas, chilled water will be supplied to individual zones as determined by the sensors in the steel to maintain the desired mold temperature.  On the Stationary side, operation is much like a continuous flow circulator loop.
