Technical service
Each installation has different characteristics, technologies, operating history and requirements.
That is why YAHAR starts with system analysis to define the most appropriate type of intervention, whether to prevent failures, correct issues, restore performance or modernize equipment.
Specialized services
Technical service ranging from scheduled monitoring to corrective interventions, installation and modernization of existing systems.
Planning
Scheduled actions to preserve components, reduce incidents and increase system reliability throughout operation.
Monitoring
Monitoring of operating parameters and conditions to identify changes before they develop into failures.
Recovery
Diagnostics and intervention to locate failures, restore proper operating conditions and recover the operation.
Implementation
Assembly, adaptation, testing and verification of the conditions required for proper startup.
Modernization
Upgrading equipment and components to improve reliability, performance and operating conditions.
Assistance
Service focused on failures that compromise system operation or operational continuity.
Systems and technologies serviced
Specialized service for different chiller configurations, HVAC systems and equipment used in large-scale commercial and industrial operations.
Service for equipment with centrifugal compressors used in chilled-water systems and higher-capacity applications.
Maintenance and diagnostics for chillers equipped with rotary screw compressors in different application configurations.
Service for chillers equipped with scroll compressors, including modular configurations and systems designed for chilled-water production.
Technical service for variable refrigerant flow systems used in commercial and industrial installations.
Analysis and maintenance of chillers, hydraulic circuits, pumps, valves, controls and associated system components.
Solutions for environments and processes that require thermal control, reliability and continuous operation.
Verification of commands, sensors, operating parameters, control devices and integrated system operation.
Upgrading existing systems to improve reliability, performance, control and operational continuity.
Chiller technology
Compressor technology and the condensation method are distinct equipment characteristics that influence its configuration, application and maintenance.
Technology used mainly in chillers designed for higher-capacity chilled-water systems.
Rotary compression technology used in chillers with different capacities and condensation configurations.
Technology used in different chiller configurations, including modular equipment and chilled-water systems.
In addition to compressor technology, chillers may use different heat-rejection methods, including air-cooled or water-cooled condensation, depending on the equipment configuration.
How we work
The intervention is defined based on the conditions observed in the system and the impact of the issue on the operation.
The goal is to identify the equipment’s actual need before defining the intervention, avoiding isolated actions that do not address the root cause of the issue.
Technical process
The sequence may vary according to the conditions found, but technical analysis remains the basis for decision-making.
Initial stage
Assessment of the need, equipment history and current operating conditions.
Analysis
Technical assessment to identify failures, anomalies or opportunities for improvement.
Execution
Execution of the solution best suited to the actual needs and conditions of the installation.
Validation
Verification of system operating conditions and behavior after the intervention.
Operational continuity
In large-scale systems, reliability and availability directly influence the continuity of the customer’s processes and activities.
That is why each service call seeks to understand the cause of the issue and define a solution compatible with the system’s actual conditions.
