Retrofit Over Replace.
Engineer the Upgrade.

Existing thermal infrastructure often has years of structural life remaining i.e., but underperforming insulation, outdated refrigerants, and legacy controls driving excessive energy costs. Cueron engineers the retrofit that brings facilities to current performance standards at a fraction of replacement cost.

Four Retrofit Disciplines.

Comprehensive retrofit engineering i.e., from assessment through execution i.e., across insulation, refrigerant, energy, and digital systems.

Insulation Retrofit

Assessment and replacement of degraded insulation systems i.e., addressing thermal bridging, moisture ingress, and aged PUF/PIR panels that have lost thermal performance.

Thermal imaging survey of existing envelope
Insulation condition assessment report
Replacement specification with improved λ values
Installation with zero operational disruption
ROI: 2-4 year payback through energy savings

Refrigerant Conversion

Migration from high-GWP HFC refrigerants (R-404A, R-22) to low-GWP alternatives (R-449A, R-290, R-744) i.e., with system modifications and safety engineering.

Refrigerant compatibility analysis
System modification engineering (seals, oil, components)
Safety system upgrades (leak detection, ventilation)
Post-conversion performance validation
ROI: Regulatory compliance + 95% GWP reduction

Energy Efficiency Upgrade

VFD retrofit for compressors and fans, electronic expansion valve installation, and control system optimization i.e., reducing energy consumption by 30-50%.

Energy audit and baseline consumption profiling
VFD and ECM fan retrofit specification
Electronic expansion valve installation
Post-installation energy performance verification
ROI: 30-50% energy reduction, 2-3 year payback

BMS / IoT Retrofit

Modernization of legacy monitoring and control systems i.e., adding IoT sensors, cloud analytics, and predictive maintenance to existing facilities.

Sensor gap analysis and instrumentation plan
IoT gateway and connectivity installation
Cloud dashboard deployment with alerts
Staff training on new monitoring platform
ROI: Predictive maintenance + compliance automation

The Retrofit Engineering Process.

A structured four-phase approach i.e., from facility assessment to validated performance improvement.

01

Facility Assessment

Comprehensive audit of existing infrastructure i.e., insulation condition, refrigeration performance, energy consumption patterns, and monitoring architecture.

02

Engineering Analysis

Thermal simulation modeling, energy baseline establishment, and ROI analysis for each retrofit option i.e., data-driven prioritization.

03

Design & Specification

Detailed engineering design for selected retrofits i.e., material specifications, installation methodology, and phased execution planning.

04

Execution & Validation

Phased installation with minimal operational disruption, followed by performance validation against design targets.
