Compressor controllers
Centrifugal, rotary screw, reciprocating, and master sequencing logic engineered to keep mixed fleets running on shared setpoints.
Controls and powerhouse integration
Total powerhouse solutions on one operator surface.
The Fischer Group combines PLC algorithms, decades of compressor field experience, and HMI systems designed for the people running the plant. The result is controls work that modernizes compressor rooms without locking customers into one OEM stack.
Control capability
Industrial controls for compressors and the equipment around them.
The Fischer Group controls offering covers the compressor, the support equipment, the valves and hardware, and the operator experience, all engineered to work together.
Centrifugal, reciprocating, rotary screw, master, and flow controllers
PLC, HMI, and SCADA systems built on proven industrial platforms
Surge protection, load sharing, sequencing, trending, alarming, trip lock, and valve maintenance
Dryer, chiller, chiller-dryer, cooling tower, and filtering system controls
Remote and local programming for troubleshooting and data monitoring.
Control scope
Beyond surge control.
Powerhouse support equipment
Dryers, chillers, cooling towers, pumps, and filtering systems brought onto a single control surface for operators.
Hardware integration
Inlet guide vanes, blow-off valves, anti-surge valves, control valves, water valves, and condensate float switches.
Operator visibility
Touchscreen HMI, Ethernet/SCADA integration, real-time logging, historian-friendly trending, and remote programming.
Operator experience
The screen the plant actually uses.
The Fischer Group's controls land in front of operators as a single trusted surface, not a tab in someone else's SCADA. Trending, alarming, sequencing, and load-sharing all run through the same logic The Fischer Group uses on its own Bone Dry dryers.
- Surge protection, load sharing, sequencing, trending, alarming, trip lock.
- Inlet guide vanes, blow-off valves, anti-surge valves, control valves, water valves, condensate float switches.
- Compressor, dryer, chiller, cooling tower, pump, filtering system, and support-equipment controls.
- Remote and local programming, historian-friendly logging.
How it looks in practice
Whole-plant relationships, not one-off installs.
The Fischer Group's controls work tends to grow. A unit controller on one compressor becomes the controls standard for the whole room.
TFG-controlled compressors at one plant
The Fischer Group installed Allen Bradley PLC controls on a customer's compressor over 20 years ago. That same plant now runs seven TFG-controlled compressors, and called The Fischer Group back for the most recent overhaul too.
Units in a single Iowa plant-wide upgrade
Four As New Refurbished Centrifugal Compressors, TFG Bone Dry dryers, individual PLC unit controls, a Master Controller, and a full SCADA system, all supplied and installed by The Fischer Group as a single turnkey scope.
First in the industry with PLC-based compressor controls
The Fischer Group pioneered open-architecture Allen Bradley PLC controls for compressed air systems in 1997. Open architecture means the customer's own maintenance team can work on the system: no OEM lock-in, no proprietary black box.
