PROTECTIVE and
SOUND ATTENUATED
ENCLOSURES
- three levels of sound attenuation
D40-6 to D175-2
D40-6s to D100-6S
FEATURES
HIGHLY CORROSION RESISTANT
CONSTRUCTION
• Stainless steel flush fitting latches and hinges tested
and proven to withstand extreme conditions of
corrosion
• Zinc plated or stainless steel fasteners
• Body made from 16 gauge steel components treated
with polyester powder coating
TRANSPORTABILITY
These enclosures are of extremely rugged construction
to withstand outdoor exposure and rough handling
common on many construction sites. The sound
deadening material is of a self-extinguishing design.
This range of enclosures are designed on modular
principles with many interchangeable components
permitting on-site repair.
EXCELLENT ACCESS
• Single side access for service and controls
• All non-service sides have removable doors and/or
panels
• Radiator fill access
• Lube oil and coolant drains piped to the exterior of
the enclosure base
• Large cable entry area for installation ease
• Double doors on both sides
• Vertically hinged doors with solid bar door stays to
hold doors in place when open.
Three configurations providing three levels of sound
attenuation
• Level 1 (WP-Industrial)
Weather protective with industrial silencer
- silencer mounted within the main enclosure body.
• Level 2 (WP-Critical)
Weather protective with critical silencer
- silencer mounted in separate upward discharging
radiator hood
• Level 3 (SA)
Weather protective with critical silencer and 100%
lined with sound deadening material
- silencer mounted in separate upward discharging
radiator hood
SECURITY AND SAFETY
• Lockable access doors which give full access to
control panel and breaker
• Cooling fan and battery charging alternator fully
guarded
• Fuel fill, oil fill, and battery can only be reached via
lockable access
• Stub-up area is rodent proof
