Project Portfolio

Challenge

Obsolete control board with no replacement parts available. Original manufacturer no longer supporting the model.

Solution

• Reverse-engineered existing control logic
• Designed custom control panel using current components
• Integrated pressure monitoring and motor protection
• Added improved diagnostics and status indication

Outcome

Compressor back in service at approximately 25% of replacement cost. Client now has documentation and readily available spare parts for future maintenance.

Challenge

Intermittent temperature swings causing inconsistent cooking. Multiple service calls from other technicians had not resolved the issue.

Solution

• Systematic troubleshooting of heating circuits and controls
• Replaced failing SSR and temperature controller
• Repaired damaged wiring and connections
• Calibrated temperature setpoints and tuned control response

Outcome

Oven returned to stable operation with precise temperature control. Provided preventive maintenance recommendations to avoid future issues.

Challenge

Freezer not maintaining temperature. Defrost timer running too frequently. Previous diagnosis suggested replacing the entire refrigeration system.

Solution

• Identified failed defrost termination thermostat
• Discovered incorrect defrost timer settings
• Repaired damaged evaporator fan wiring
• Reprogrammed defrost schedule for actual usage patterns

Outcome

Freezer operating properly with correct defrost cycling. Total repair cost under $500 versus $15,000+ for unnecessary refrigeration replacement.

Scope

• Electrical load calculations for commercial kitchen equipment
• Power distribution design and panel schedules
• Dedicated circuits for kitchen equipment (ovens, fryers, steamers, etc.)
• Lighting layout for dining and kitchen areas
• Emergency lighting and exit signs
• HVAC equipment power connections

Deliverables

Complete electrical drawings stamped by licensed engineer, approved by ESA for permit. Contractor feedback confirmed designs were clear and practical to install.

Design Elements

• Single-line and schematic diagrams
• Motor starters for HVAC fans and pumps
• VFD integration for variable speed control
• Temperature and pressure monitoring
• Safety interlocks and alarm outputs
• Communication interface to BMS

Deliverables

Complete electrical design documentation including schematics, panel layout, wire lists, and bill of materials. Panel fabricated by local shop and commissioned successfully.

Challenge

20-year-old vacuum system with proprietary controls. Manufacturer out of business, no parts or service available.

Solution

• Analyzed existing system operation and control requirements
• Designed new control panel with modern components
• Implemented automatic and manual operating modes
• Added remote monitoring and diagnostic features
• Provided complete documentation for future service

Outcome

Vacuum system operating reliably with improved performance. Practice avoided costly replacement and has serviceable system with available parts.

Challenge

Intermittent circuit breaker trips with no obvious pattern. Multiple service calls had not identified root cause.

Solution

• Performed systematic electrical load testing during all operating modes
• Identified failing contactor causing current spikes
• Discovered loose connection in heating element circuit
• Replaced faulty components and secured all connections
• Verified proper operation under full load conditions

Outcome

Dishwasher operating reliably with no further trips. Restaurant able to maintain service during all operating hours.

Scope

• Field verification of all electrical panels and circuits
• Documentation of equipment connections and ratings
• Panel schedule updates with accurate circuit identification
• Single-line diagram of power distribution
• Equipment layout with circuit assignments

Outcome

Complete, accurate electrical documentation for facility management. Drawings used for subsequent renovation planning and contractor bidding.

Challenge

Burners not igniting consistently. Flame safety system triggering lockouts. Gas flow issues on several burners.

Solution

• Cleaned and adjusted burner orifices and pilots
• Replaced failed flame sensors and ignition modules
• Adjusted gas pressure and air mixture
• Tested and verified all safety interlocks
• Performed leak check on all gas connections

Outcome

All burners igniting reliably with proper flame characteristics. Safety systems functioning correctly. Kitchen back to full operation.
