Although not standard on Wood-Mizer DH Kilns you may choose to add on this optional Spray System Kit
which will provide extra control when drying. The Sprayers are designed to be automatically activated by
the system when needed and help with regulating the relative humidity within the kiln chamber.
Wood-Mizer spray systems are designed to inject into kiln air one gallon of water per hour for every 1000
BF. Because air temperature affects the quantity of water evaporated (warmer air holds more water
vapor), we need to balance the quantity of water vapor to the kiln capacity. DH units with small heaters
will require proportionately less water than larger units with bigger heating capacity. There are options
available for every unit so be sure that the kit you are purchasing matches the specifications for the unit
that it will be installed in.
Wood-Mizer encourages boosting water pressure to 100 psi for the spray system to have the best results.
Commonly this is done with the use of a jet pump, which can be purchased through Wood-Mizer if
requested. Contact your Wood-Mizer Sales or Service Representative for more information.
