Core Capabilities

Applied engineering services built around real plant-floor constraints, not theoretical models.

Thermal Mapping & Diagnostics

Infrared thermography paired with CFD modeling to locate hot spots, flow dead zones, and fouling patterns in cooling towers and boiler systems. We deliver a ranked list of corrective actions with expected impact on heat transfer rates.

Pipe Network Stress Analysis

Detailed finite element analysis of high-pressure and high-temperature piping systems. We model thermal expansion, water hammer, and support loads to identify fatigue-prone welds and recommend rerouting or expansion loop additions.

Preventative Maintenance Planning

Condition-based schedules derived from actual operating data and wear patterns. We specify inspection intervals, sensor placement, and trigger thresholds for heat exchangers, cooling towers, and boiler feedwater systems.

Heat Exchanger Retrofit Design

Redesign of plate-and-frame and shell-and-tube units to improve energy recovery and process consistency. We evaluate baffle geometry, gasket materials, and flow configurations against actual fouling and temperature profiles.

Thermodynamic System Audits

Full-cycle efficiency audits for steam, hot water, and chilled water loops. We measure actual vs. design performance, identify parasitic losses, and provide a prioritized list of mechanical and control adjustments.

Flow Optimization & Balancing

Field measurement and modeling of pump curves, valve positions, and pipe diameters to balance flow across parallel cooling tower cells or boiler feedwater headers. We target a flow variance of less than 5% between branches.

Frequently Asked Questions

Common inquiries about our industrial engineering services and approach.

What types of facilities do you typically work with?

We primarily serve heavy manufacturing plants and processing facilities — steel mills, chemical plants, food processing lines, and large-scale commercial boiler installations. Our diagnostics are tailored to industrial environments where fluid dynamics and thermal loads are critical to uptime.

How do you conduct thermal mapping on existing equipment?

We use a combination of infrared thermography, contact temperature sensors, and computational fluid dynamics modeling. The process is non-intrusive and typically completed within two to three days on site, depending on the size of the cooling tower or heat exchanger network.

Do you provide preventative maintenance schedules after an analysis?

Yes. Every diagnostic engagement includes a detailed maintenance planning report. We identify failure-prone sections, recommend inspection intervals, and provide sensor placement guidance so your team can monitor critical parameters between our visits.

What is the typical timeline for a pipe network stress analysis?

A standard stress analysis for a boiler feedwater or process piping system takes four to six weeks from initial site survey to final report. This includes modeling thermal expansion loads, pressure transients, and support spacing, followed by a retrofit design if needed.

Can you work with our existing engineering team during the project?

Absolutely. We coordinate closely with facility engineers and maintenance leads throughout the diagnostic and remediation phases. Our goal is to transfer knowledge and provide clear documentation so your team can sustain improvements long after we leave the site.

How We Work

From initial request to implemented result — a structured engineering process.

1

Request & Data Collection

You submit system specs, site drawings, and operational history. We review and request any missing instrumentation data or access details.

2

On-Site Diagnostics

Our engineers perform thermal mapping, pressure logging, and flow measurements. Typical duration is 2–5 days depending on plant size and piping complexity.

3

Analysis & Modeling

We run CFD simulations and stress models against your operating envelope. Results are cross-checked against historical failure records and OEM tolerances.

4

Report & Recommendations

A prioritized list of findings with quantified risk levels, expected efficiency gains, and estimated downtime for each intervention.

5

Implementation Support

We provide piping isometrics, sensor placement drawings, and control logic updates. On-site supervision available for critical retrofits.

6

Follow-Up & Monitoring

Post-implementation data review at 30 and 90 days. Adjustments to maintenance schedules and control parameters as needed.
