CONTROLS
SEM MX Enclosure Controls
Mounted to Enclosure exterior
Configured to Interface with Machine Controls
Easy to access
Offer complete system control
Competitor's Controls
Internal systems controls made accessible (somewhat) by random cutouts in face of enclosure.
Difficult to access
Unattractive
Extra openings decrease overall sound deadening capability
Gaps and voids create housekeeping/operating environment issues as particles can escape the enclosure (Spots on image are due to high levels of dust)
MACHINE FEEDING
SEM's MX Enclosure Feed Opening
Convenient Door-in-a-Door Design
Seals tightly when not being feed
Provides an added measure of flyback protection
Maintains sound reduction efficiency
Competitor's Feed Opening
Permanent Cutout in face of enclosure
No added flyback protection
Permanent opening allows noise to escape
VISUAL STATUS
SEM's MX Enclosure
Sound proof window allows operators to see if collection bags are full without opening the enclosure doors
Competitor's Enclosure
Usually there is no window
Operators are required to open the enclosure door to check the status of waste collection bags
FLEXIBILITY/VERSATILITY
SEM's MX Enclosure Modular Design
Configured specifically to the application requirements
Erected and tested at factory then disassembles and shipped for complete quality control
Can be easily reconfigured or moved if applications change
Roof is supported by rugged frame, not walls - any or all wall panels may be removed without the need for additional support or any disturbance of ventilation, filter system or wiring.
Competitor's Permanent Construction
Built on-site like a wooden shed
Quality is dependant on installer and materials of construction
Not reconfigurable - not movable
Walls cannot be removed with first removing "screwed in" roof
Roof removal causes disturbance to ventilation, filter system an wiring
FAST SETUP
SEM's MX Enclosure
Done in a couple of hours
Minimum disturbance to the work environment
Almost no "clean-up" required
Competitor's Enclosure
Often takes a full day or more
Can cause significant interuptions and disturbances in the work environment
