What it does

Total control of the machine, no generic PLC.

Complete automation panel, designed and built to measure for the contracted configuration. Switching, protection and automation already sized for the system.

Total controlAC or EC fans, proportional or on/off expansion valves, heating coils, dampers and UV light. Faults, alerts and filter saturation monitored.
Fits the main AHUsOperates with air handling machines from the main manufacturers. Suited to hospitals, pharmaceuticals, laboratories and industrial processes.
Built-in sensorsTemperature, humidity and pressure transducer already in the panel. In the room, the module with display reads temperature, humidity and CO₂ and receives the setpoint.
Inside the panel

From the HMI to the panel, from the panel to the AHU

The touchscreen HMI sits in the conditioned room: it shows temperature, humidity and airflow and receives the setpoint. It talks to the panel over Modbus, wired, or over the STG wireless network. In the panel, the STG AHU controller commands the AHU peripherals.

Where it acts

Four control points on the same AHU

All solved in the control layer, without replacing the machine.

  1. 01Dampers and fresh airDampers driven by the room sensor's CO₂ reading: demand-controlled fresh air.
  2. 02Airflow controlAC or EC fans with airflow control by the controller itself.
  3. 03Temperature and humidityValve and heater switching, including in AHU kits, with ready-made humidity control logic.
  4. 04Filter monitoringFilter saturation monitored by a differential pressure transducer, with alert.

Why Storge

Hardware, firmware and panel from the same engineering.

STG line controllers, sensors and the electrical panel are designed and manufactured by Storge in Piraquara, Brazil. That vertical integration is what allows the panel to be adapted to your machine.

  • Replaces the existing panelHigh-level automation in a compact panel, keeping the machine you already have.
  • Firmware dedicated to the applicationHumidity logic, alarms and fail-safe protection ready, with no PLC programming.
  • Wireless room sensorThe room module reads temperature, humidity and CO₂ in the conditioned space and sends them to the panel over the STG wireless network.
  • Hospitals
  • Pharmaceuticals
  • Laboratories
  • Industry
