Maintaining pressure within a system that has multiple compressors require a well-defined, pre-engineered solution. AirSequal features the ability to control 2 to 6 rotary screw compressors with a need for basic multiple compressor automation. This automation ssystem orchestartes auto sequence rotation, base/trim control and flow calculations to control starting/stopping and loading/unloading based on a single pressure set point. Save on energy costs, prolong the life of your system and enjoy headache-free operations with AirSequal Multiple Compressor Automation.
Add an optional flow meter to unlock FlowSeq. As demand changes, the AirSequal will automatically adjust to run the appropriate compressor lineup for maximum efficiency.
Auto rotation functionality is available with the intent of maintaining equal runtime across the compressors. Two auto rotation functions are available: Compressor Runtime Based Rotation and Preset Sequence Based Rotation.
Full Calendar based system control. Run the system how and when you want.
Example: Monday, Wednesday, Friday at 5:00pm the production enters into a low demand period. You can rotate smaller HP units to the lead position and turn off larger HP.
Note: The FlowSeq function would do this automatically, but this method does not require a flow meter.
For intermittent compressed air usage, pressurize the system only when it's needed.
The PLC is continuously calculating pressure rate of change over time. This set point is used to prevent falsely starting more compressors than needed when pressure is tracking in the right direction towards the Start/Load set point. If pressure is less than the Start/Load set point, but increasing, the next compressor will not start.
The PLC is continuously calculating pressure rate of change over time. This set point is used to prevent unloading too many compressors when demand decreases and pressure is tracking in the right direction towards the upload set point. If pressure is greater than the Start/Load set point, but decreasing, the next compressor will not unload.
Base/Trim control may be utilized to take advantage of systems containing one or more compressors with modulation capabilities. The number of compressors allowed to simultaneously trim is defined via the operator interface.
When variable capacity compressors are utilized, algorithms are in place to insure all compressors are fully loaded prior to adding additional capacity.
Don't temporarily demand events control your system. The AirSequal continuously monitors all system conditions to make sure true system events require the AirSequal to deploy a command. This prevents unnecessary and/or erratic compressor starts.
