Sound Attenuated Canopy – SAT
The Sound Attenuated Canopy which is produced by Plasma and CNC Turrets not only meets with residential sound control requirements but also ensures the correct cooling aeration required for normal operation. Gensets can be installed in the open air to save space.
Modular design for ease of maintenance and access.
Special high-temperature flame-retardant sound insulation foam.
Slap-up hinge and door handle.
Mild Steel Steel Plate with a powder coated surface finish is utilised for the construction of the upper canopy.
Soundproof foam varies between 40mm to 100mm depending on the degree of attenuation required.
Standard Attenuation Noise Level: 75~80dB within 1m; 72~75dB within 7m.
The Silencer is installed inside the soundproof canopy within a specially manufactured firewall compartment.
The control panel is installed inside the canopy and has a set mounted ATS

Our AMF control panel uses a Deep Sea control module. The Module is an Automatic Mains Fail controller for genset applications. The AMF panel is used where the local utility mains supply is backed up by an appropriately sized generating set. The AMF panel monitors the local mains supply; if this supply should fail, or fall outside pre-set limits the AMF panel will control the pre-heating, fuel solenoid and starting of the generating set either through relays and contacts or via engine ECU if available. The control panel is equipped as below:

Auto Mains Failure Control Panel:
DeepSea 4520 Electronic Controller with Automatic Transfer Switch
Emergency Stop Push Button
Static Battery Charger.
Four-Pole Electronically & Mechanically Interlocked ATS.
