Background
In packaged drinking water (AMDK) production, the clean room environment is not a background condition — it is an active quality variable. Off-spec temperature, humidity drift, or a drop in positive pressure can affect product quality, raise contamination risk, and disrupt the production process before anyone on the floor notices.
The client's facility in Pasuruan, East Java, had no automated system to monitor AHU conditions continuously. Environmental parameters were not tracked in real time, early warning of deviations was not available, and decisions about clean room conditions relied on manual checks rather than live data.
PT Phase Delta Control was engaged to implement an AHU Monitoring System that would put every critical clean room parameter on a single real-time web-based dashboard — giving the facility team immediate visibility and early warning capability without manual intervention.
System Requirement
Monitor temperature continuously across AHU units and clean room areas
Track humidity levels in real time to protect product quality and production consistency
Maintain and monitor positive pressure to prevent contamination from outside air
Detect AHU system faults early and raise alerts before clean room conditions degrade
Provide real-time data visibility for fast, accurate operational decision-making
Project Implementation
Component | Function |
|---|---|
Temperature Sensor | Monitors clean room and AHU temperature continuously |
Humidity Sensor | Tracks relative humidity levels in real time |
Pressure Sensor | Measures positive pressure to confirm clean room integrity |
Data Server | Collects and processes sensor data from all monitored points |
Web-based Dashboard | Displays live parameters and raises alarms when readings drift out of range |
System Description
The AHU Monitoring System works by collecting data from sensors installed across the AHU units and clean room areas. Sensors measure temperature, humidity, and positive pressure continuously, feeding readings to the server in real time.
The server processes incoming data and pushes it to a web-based dashboard accessible from any workstation. When a parameter drifts outside its configured normal range a temperature spike, a humidity shift, or a drop in positive pressure the system raises an alert immediately, giving the facility team time to respond before clean room conditions fall out of spec.
All parameter data is logged continuously, building a historical record that supports trend analysis, audit ocumentation, and regulatory compliance reporting.
Summary
The AHU Monitoring System gave the facility its first continuous, real-time view of clean room conditions across all monitored parameters. Environmental data that had previously depended on manual checks became automatically logged, instantly visible, and actively alarmed putting the facility team in a position to act on deviations before they reached the product.
Key Outcomes
Product quality maintained through continuous environmental monitoring
Contamination risk reduced by real-time positive pressure and humidity tracking
Faster response to AHU faults with automatic early-warning alerts
Remote monitoring accessible from any workstation, anywhere
Audit and regulatory compliance supported by full historical data logs
