7. Equipment Description
7.1 Chamber The chamber contains four (4) rotary spray assemblies mounted
to the top, sides, and bottom The spray assemblies provide repeatable spray coverage to the process parts’ exterior surfaces and the chamber’s interior during all phases of the cycle (pre-rinse, wash, final rinse) Each spray assembly includes strategically located spray orifices, along with removable static spray ball on the end of the arm for additional spray coverage The spray assemblies are constructed of 316Lss and have fluid-driven rotary unions with hubs and bushings composed of 316Lss and USP Class VI thermoplastic materials Each spray assembly includes a magnetic proximity switch to confirm rotation during all phases of the cleaning cycle • Chamber construction − Installation Type: Floor Mounted − Thickness: 12 ga

− Insulation: 2" thick chloride free insulation with 304ss sheathing on door(s) only 05" thick closed cell foam insulation on chamber and sump
− Door(s): Manually operated side-hinged door(s) with a laminated tempered glass viewing window, inflatable EPDM door gasket with low pressure switch to alarm, adjustable position door stop, and proximity switch
to confirm door closure − Design: Atmospheric
− Material: 316Lss wetted surfaces / 304ss non-wetted surfaces −Interior Finish: 20 µin Ra with welds ground and polished
−Exterior Finish – Load/Unload Sides: 32 µin Ra with welds ground and polished − Exterior Finish – Maintenance Space: Bead blasted and/or welds color cleaned • Chamber connections and components − Four (4) Rotary spray assemblies − One (1) Active rack connection – spring loaded PTFE coupler mates with parts rack to provide spray coverage
to the active rack piping, targeting the interior surfaces of process parts − Two (2) Rail assemblies for rack guidance with load side wheel stop − One (1) Sump outlet strainer ( 3 / 8 " perforated core with 40 mesh overlay) − One (1) Chamber LED light − One (1) Temperature transmitter with 0-100 °C range and 4-20 mA output − One (1) Toroidal conductivity sensor with 0-100 mS/cm range and 4-20 mA output − One (1) Contacting conductivity sensor with 0-10 µS/cm range and 4-20 mA output − One (1) Level transmitter (pressure type) with 0-12" range and 4-20 mA output
− Two (2) Water inlet connections (10" tri-clamp) − Two (2) Chemical inlet connections (05" tri-clamp) − One (1) Exhaust connection (60" flange for SP333, 80" flange for SP443/SP444 - See Table 7: Dryer Utilities ) Usable space dimensions vary by model size, as shown in Table 4: Usable Space Dimensions The usable space dimensions identify the maximum parts loading dimensions, when taking rack design into consideration
