Protecting electrical cubicle
The electrical cubicle combines one of the most advanced systems to ensure the machine’s reliability as well as the network in which it is connected to:
• RFI filters reducing harmonic disturbances in the network
• AC chokes against high voltage peaks
• Unit controller
• High-frequency variable speed drive
• DC/DC converter energizing the magnetic bearing controller in case of power failure
• Magnetic bearing controller dynamically adjusting the blower’s shaft position
• LC filters protecting the permanent magnet motor of harmonics
-
Compact and low heat rejection frequency drive
• The high-frequency variable speed drive is the component ensuring the motor’s optimum operation
• Water-cooled, it provides mimum heat rejection and space requirement
-
Magnetic bearing controller
• Compiles information from position sensors to dynamically adjust the shaft’s position
• Full control of the rotor is guaranteed by the magnetic force adjustment
• No external source required nor UPS in case of power failure. Energy is pulled from the variable frequency drive through a DC/DC converter.
-
Minimum internal temperature with heat exchanger cooling fan
• Reduces cooling water temperature for the permanent magnet motor and drive
• Cools down mechanical components inside the machine to ensure the lowest opearting temperature and longest lifetime
• Centralized warm cooling air to one single common location on the machine’s roof to ease ducting and heat extraction
-
Actuated modulating blow-off valve
• Integrated and factory mounted modulating blow-off valve protecting the blower from overheating
• Assures smooth operation during rapid process changes
• Advanced control algorithm which allows the unit to run in the most efficient way in an extended operating flow range (from 100% to 0% turndown) and unlimited number of starts and stops
-
Integrated blow-off silencer
• Integrated and factory mounted blow-off silencer to reduce noise from blow-off operation
• Attenuated noise through built-in internal turns
-
High-efficient process air filters
• Separated process air path to ensure lowest intake temperature and highest mass flow
• Parallel high-efficiency filters
• Easily accessible from the back of the machine and replaceable
-
Separated process air inlet
• Manifold leading air directly from intake point to blower’s impeller to separate it from internal heat
• Maintains the process air temperature to a minimum to increase mass flow delivered by the blower
-
Magnetic bearing turbo blower
• Magnetic bearing technology for highest reliability of all of your operations independently from the downstreams conditions
• Water-cooled permanent magnet motor maintaining the lowest running temperature and longest component lifetime
-
Check valve
• High-efficiency check valve to protect blower when not operating
• Lowest pressure drops to minimize the performance’s impact
