Facilities Management Services

Alstern delivers a comprehensive and forward-thinking approach to building maintenance by integrating traditional engineering practices with cutting-edge digital technologies. By Internet of Things (IoT) sensors and Building Management Systems (BMS), our Smart M&E Maintenance framework ensures that facilities and enhance for long-term functionality, efficiency, and resilience. We offer full-suite ACMV maintenance services and electrical maintenance services.

Preventive & Predictive HVAC Maintenance

Through regular inspections and advanced sensor monitoring, we detect potential issues early and forecast failures before they occur. This proactive maintenance safeguards your HVAC systems’ performance, minimises costly repairs, and improves operational efficiency. Benefits include extended equipment lifespan, improved energy efficiency, reduced operational costs, and enhanced occupant comfort.

Corrective & Conditional Maintenance

By provide a responsive and intelligent maintenance strategy that addresses both unexpected failures and performance-based needs. When breakdowns occur, our team delivers fast, effective corrective maintenance to restore full system functionality with minimal disruption. In parallel, our conditional maintenance approach uses real-time monitoring of key performance indicators such as temperature, pressure, and airflow to identify issues as they arise and perform service only when necessary. This dual approach minimises downtime, reduces unnecessary maintenance costs, and ensures your systems operate efficiently and reliably.

Alstern provides Preventive, Predictive, Corrective, and Conditional Maintenance under long-term service agreements, with routine inspections and performance checks scheduled at defined intervals. This balanced maintenance approach helps to extend the operational life of equipment, reduce unplanned downtime, and maintain consistent system efficiency.

Cooling Tower Refurbishment

Cooling Tower Refurbishment services offer a cost-effective and efficient solution to extend the lifespan, performance, and energy efficiency of existing cooling towers without the need for complete replacement. Our eco-friendly Cooling Tower Refurbishment process helps to reduce energy consumption and environmental impact, while improving cooling capacity, lowering operational costs, and minimising maintenance requirements.

The cooling tower refurbishment process:

  • Inspection and re-alignment of motors and fan blades
  • Repair and rebuilding of corroded areas
  • Using high-strength industrial putty and anti-corrosion coatings
  • Replacement of heat dissipation infills with high-quality materials
  • Pre- and post-testing and commissioning to ensure optimal performance

AHU/PAHU EC Fan Retrofit & System Upgrades

Alstern delivers advance retrofitting EC fans solutions for Air Handling Units (AHUs) and Primary Air Handling Units (PAHUs), replacing conventional asynchronous AC fans with high-efficiency Electronically Commutated (EC) fans. These retrofits provide precise fan speed modulation via integrated variable speed control, optimising airflow and static pressure across varying operational loads. By upgrading to EC fan, clients benefit from significantly improved energy efficiency, reduced electrical consumption, lower thermal output, and increased system reliability. The result is a more stable, efficient HVAC operation with extended equipment lifespan and reduced operational costs.
