Engineering & Software Portfolio
A showcase of precision-engineered solutions by ISOL. From industrial automation and custom PCB hardware to AI computer vision and enterprise cloud platforms across Pakistan.
Industrial Washing Machine Control System
Client: Pearl Continental (PC) Hotel, Lahore
Project Overview: The Automated Industrial Washing Machine Control System was engineered for the commercial laundry facility at Pearl Continental (PC) Hotel, Lahore. The project involved replacing an outdated, failed proprietary controller with a customized, highly reliable microcontroller-based control board designed and built locally in Pakistan. Key Challenges Solved: The original imported electronic controller had failed, halting heavy-duty laundry operations for hundreds of hotel rooms. Sourcing an overseas replacement was cost-prohibitive with months of downtime. ISOL reverse-engineered the system architecture, built a custom industrial-grade controller board, and developed firmware tailored to PC Hotel's operational standards. Key Features & Engineering: • Automated Multi-Stage Washing: Automated sequence control for pre-wash, main wash, chemical injection, multiple rinses, and high-speed extraction spinning. • Precise Chemical Dosing Automation: Timed relay triggering for automated liquid detergent, bleach, and fabric softener injection pumps. • Water Level & Temperature Management: Pressure-transducer water level monitoring and thermal sensor control for steam heating valves. • Variable Frequency Drive (VFD) Interfacing: High-torque acceleration/deceleration motor control to handle unbalanced wet linen loads safely. • Industrial Safety Interlocks: Pneumatic door lock validation, vibration switch shutoff, and emergency stop overrides preventing drum rotation during unlatched states. Impact & Results: Restored 100% operational throughput for PC Hotel laundry operations within 10 days, saving over 70% in replacement equipment costs compared to foreign OEM imports, with zero control failures under heavy continuous 24/7 duty.
Automated Weather Station (AWS) Telemetry
Clients: Nestlé Pakistan Ltd. & PARCO Oil Refinery Ltd
Project Overview: The Automated Weather Station (AWS) R&D and Installation initiative was designed and deployed for multinational industrial giants Nestlé Pakistan Ltd. and PARCO Oil Refinery Ltd. The system provides real-time, autonomous meteorological and environmental intelligence across critical agricultural and refinery installations. Objectives & Field Conditions: Both clients required continuous environmental tracking in remote outdoor environments without reliable grid electricity or local Wi-Fi. The stations needed autonomous solar power harvesting, rugged weatherproof enclosures (IP66), and cellular telemetry transmitting to cloud analytics dashboards. Key Features & Technologies: • Rugged Multi-Sensor Array: Precision calibrated sensors monitoring wind speed and direction (anemometer), ambient air temperature, relative humidity, atmospheric barometric pressure, solar irradiance, and rainfall accumulation. • Autonomous Solar Energy Management: Integrated solar PV panel with intelligent MPPT battery charging circuit ensuring uninterrupted 24/7 operation through consecutive days of overcast weather. • Cellular IoT Telemetry: GSM/GPRS micro-modem sending encrypted telemetry packets at configurable sampling intervals (1 to 15 minutes). • Cloud Dashboard & SCADA Integration: Real-time web visualization, historical trend graphing, threshold alerts for hazardous wind/heat conditions, and automated daily climate reports. Impact & Results: Provided Nestlé with essential micro-climate data for agricultural supply chain optimization and water management. Delivered critical wind speed and atmospheric pressure telemetry for safety compliance and flare-stack monitoring at PARCO Oil Refinery installations.
Localized DRY ICE Production Machine
Client: Industrial Cryogenic Client
Project Overview: The Localized Dry Ice Production Machine represents a significant domestic engineering milestone in Pakistan: developing an industrial cryogenic hydraulic press to produce solid carbon dioxide (CO₂) dry ice blocks and high-density pellets locally, eliminating dependence on costly European imported machinery. Engineering & Cryogenic Challenges: Dry ice production requires injecting liquid CO₂ at high pressure into an expansion chamber where it flashes into CO₂ snow at -78.5°C (-109.3°F). The machine then drives a heavy hydraulic piston at pressures up to 200 bar to compress the snow into dense, uniform blocks before automated ejection. Key Features & Automation: • Cryogenic CO₂ Injection Control: Automated high-pressure cryogenic solenoid valves precisely meter liquid CO₂ volume per compression cycle. • Dual-Cylinder Hydraulic Sequencing: Proportional hydraulic valve control governing main compaction ram and vertical chamber opening cylinders. • Heavy Industrial Microcontroller Controller: Custom control panel featuring multi-line HMI display, cycle timing adjustments, and pressure transducer feedback. • Operator Safety & Pressure Relief: Multi-tier safety interlocks including thermal pressure relief valves, emergency chamber venting, and safety light curtains. Impact & Results: Successfully manufactured dense industrial dry ice blocks locally with rapid cycle times under 90 seconds per block. Reduced capital machinery acquisition costs for the client by over 65% while providing complete local parts availability and maintenance support in Lahore.
Industrial RO Plant Automation & Telemetry
Client: Industrial Water Treatment Facility
Project Overview: Designed and commissioned a fully automated electronic control and monitoring system for commercial and industrial Reverse Osmosis (RO) water purification facilities. The system replaces manual valve operation with automated multi-stage pump sequencing and online water quality telemetry. Key Automation Modules: • Multi-Stage Pump Sequencing: Automated start/stop sequencing for low-pressure feed pumps, pre-filter dosing pumps, and high-pressure multistage booster pumps with dry-run protection. • Automated Membrane Backwashing & Flushing: Periodic automated high-velocity flush cycles using motorized ball valves to clear mineral scale and extend membrane service life. • Inline Water Quality Monitoring: Real-time monitoring of raw and product water TDS (Total Dissolved Solids), electrical conductivity (EC), and pH levels. • Flow Rate & Pressure Transducers: Digital flow sensors calculating instantaneous flow (L/min) and total cumulative throughput, with differential pressure monitoring across cartridge filters. • Cloud & Local Alarms: Visual strobe alarms, automated low-inlet pressure shutdowns, and remote status monitoring. Impact & Results: Eliminated catastrophic membrane fouling incidents through autonomous scheduled backwashing, reduced water wastage by 18%, and provided plant operators with continuous digital transparency on water purity standards.
