60% Lower cost than the PLC/HMI quote

8 Temperature points monitored live

5 sec Data poll interval

Goose HeatWatch: live multi-point temperature monitoring panel, on site.

Executive Summary

A mid-sized dairy plant in Kerala had relied on the same mechanical chart recorder to monitor pasteurisation temperature for fifteen years. When that system failed, the plant faced a choice between a costly full control-system retrofit and a more targeted solution.

Goose Industrial Solutions delivered Goose HeatWatch, a lightweight monitoring retrofit that provided real-time visibility, trend analysis, automated alerts and audit-ready reporting, without replacing the pasteuriser's existing control system. The completed installation was delivered for approximately ₹80,000, around 60% below the ₹2,00,000 quote for a comparable PLC/HMI retrofit, and was commissioned without a significant production stoppage.

This case study sets out the challenge, the solution and the measurable business impact, and considers what it means for other legacy plants across India's dairy and food processing sector.

The Challenge

For fifteen years, a pasteuriser at the plant operated without a PLC, an HMI or any digital interface. Its only record of temperature and hold time came from a mechanical chart recorder: a stylus tracing readings onto a spinning paper disc, shift after shift. Operators reviewed the paper trace, signed off, and filed it away, often for months at a time.

When the recorder's stylus mechanism seized and its paper drive stopped turning, the plant lost the only record of its most food-safety-critical process: pasteurisation temperature and hold time.

Around this time, the plant appointed a new manager with a clear set of modern monitoring requirements. He needed:

1. • Live data on screen, rather than a paper trace reviewed only after the fact

   • A dashboard accessible from his computer, to check pasteuriser health without walking the floor

   • Trend analysis, to identify drift before it became a deviation

   • An automated summary, to remove the need to read raw temperature logs manually each morning

   • Alarm triggers, so a temperature excursion would not go undiscovered for a full shift

   • Customisable reporting, to support internal reviews, audits and management updates

His objective was clear: bring the plant's oldest machine into line with modern monitoring standards, without necessarily replacing it.

To meet these requirements, the plant approached several automation vendors. One proposal, a full retrofit incorporating a new PLC and HMI panel, was quoted at ₹2,00,000. While technically workable, it required new wiring and a revised control philosophy for a machine that had run reliably for fifteen years, at a cost disproportionate to what was fundamentally a data-visibility requirement rather than a control-system fault.

The Solution: Goose HeatWatch

Goose Industrial Solutions took a different view of the problem. The pasteuriser's mechanical process remained sound; what had failed was its ability to communicate. Goose HeatWatch was designed precisely for this gap: a lightweight monitoring retrofit that sits alongside an existing control system and gives it a digital voice, without the cost or disruption of a full automation overhaul.

Requirement	Goose HeatWatch capability
Live data on screen	RTD temperature sensors and an edge data logger feeding a real-time display at the pasteuriser.
A dashboard accessible remotely	A web-based dashboard accessible from the manager's desk, showing the live status of every monitored point.
Trend analysis	Historised trend graphs covering temperature, hold time and cycle patterns over days, weeks and shifts.
An automated summary	A daily and shift summary highlighting deviations, drift and anything needing attention, with no manual log-reading required.
Alarm triggers	Configurable high and low temperature and hold-time alarms, flagged on screen and via alert.
Customisable reporting	One-click export to PDF or Excel, formatted for internal review or regulatory audit.

No new PLC was required. No control logic was rewritten. The pasteuriser, mechanically sound with years of service life remaining, was left undisturbed. Sensors, an edge logger and a dashboard were layered on top of the existing setup, and the system was commissioned without stopping production for more than a few hours.

Technical Overview

Goose HeatWatch is built on a compact, purpose-designed architecture that balances performance, reliability and cost:

Device	Raspberry Pi 5 (4GB)
Sensor interface	PPI AIME 8U, 8x RTD channels
Database	InfluxDB (time-series), 2-year retention
Poll interval	5 seconds
Display	7" HDMI touch panel plus web dashboard
Commissioning	No production stoppage beyond a few hours

Investment and Value

The completed HeatWatch installation was delivered for approximately ₹80,000, around 60% below the ₹2,00,000 quoted for a comparable PLC/HMI retrofit. This outcome reflects Goose's approach of addressing the actual requirement, visibility, trending, alerting and reporting, rather than the larger and more expensive problem the plant did not have: a faulty control system.

Option	Cost
PLC / HMI full retrofit (quoted)	₹2,00,000
Goose HeatWatch (delivered)	₹80,000, approximately 60% lower

The HeatWatch retrofit delivered the same visibility outcomes for well under half the quoted PLC/HMI cost.

For every ₹100 quoted for the PLC/HMI retrofit, ₹60 stayed in the plant's budget.

Results and Business Impact

7. • Transitioned from paper-based records to a live digital dashboard in a single deployment, with no paper charts filed since

   • Delivered real-time visibility into the plant's most critical food-safety process, accessible directly from the manager's desk

   • Replaced manual, reactive monitoring with automated alerts for temperature and hold-time excursions

   • Enabled audit-ready reporting at the click of a button, in place of manual compilation from paper archives

   • Achieved a total installed cost around 60% below the nearest competing quote, by matching the solution to the actual requirement

Platform Overview

The value of Goose HeatWatch is realised in the software layer the plant manager uses every day. The platform provides:

Live Monitor: all eight channels at a glance, updated every 2 seconds.	Trends: overlaying all sensors to identify drift and correlations.
History: single-sensor deep dive on the pasteuriser channel.	History: hot water channel, with CSV, Excel and PDF export.
Settings: per-channel HiHi/Hi/Lo/LoLo alarm thresholds, editable on site.	Usage: system health, uptime, alarms triggered and data export.
About: device, sensor interface, database and polling details.	Live Monitor in dark mode, for round-the-clock control room viewing.

Broader Industry Relevance

This project reflects a wider pattern across India's dairy and food processing sector. Many plants continue to operate legacy equipment installed before PLCs became standard: mechanically reliable, but invisible to modern monitoring and reporting practices. The common assumption is that such equipment requires a full automation overhaul.

Goose HeatWatch demonstrates an alternative. Where the underlying equipment remains mechanically sound, the requirement is not replacement, but visibility, and that visibility can be delivered quickly, affordably and without disrupting production.

Conclusion

Goose HeatWatch shows that meaningful digital transformation does not always require significant capital investment or disruptive retrofits. By focusing on the specific requirement, visibility, rather than defaulting to a full control-system overhaul, Goose Industrial Solutions delivered a solution that met every requirement the plant set out, at a fraction of the anticipated cost and with minimal disruption to operations.

For dairy and food processing plants running legacy equipment, the lesson is clear: older machinery does not need to be replaced to meet modern monitoring standards. It simply needs to be heard.
