Specialized Services – Hot Tapping | Pipe Freezing | HRW | Coil Replacement
Advanced Industrial & HVAC Maintenance Services Across the UAE
Econovo provides specialized pipeline and HVAC maintenance services designed to keep your system running without shutdowns, safety risks, or costly interruptions. Our team handles complex operations such as hot tapping, pipe freezing, heat recovery wheel servicing, and coil replacement with precision and full compliance with UAE standards
Hot Tapping
Hot tapping creates a new connection to an existing pressurized pipeline or vessel without shutting down the system. This method allows installation of new branches or measurement instruments while operations continue normally.
Why clients choose us:
- No interruption to flow
- Safe handling of live systems
- Fast installation with minimal downtime
- Fully controlled and certified procedure
Pipe Freezing
Pipe freezing isolates a section of a pipeline by forming a temporary ice plug. This eliminates the need to drain the entire system during maintenance or modifications.
Advantages:
- No water wastage
- No contamination risk
- Safe isolation for valve or pipe replacement
- Faster and cleaner than system drainage
Heat Recovery Wheel (HRW)
Heat recovery wheels improve HVAC efficiency by transferring heat between exhaust and fresh air streams. Regular servicing ensures the wheel performs at peak efficiency.
Our services include:
- Cleaning and restoration
- Bearing inspection and replacement
- Seal alignment and wheel balancing
- Performance optimization to reduce energy costs
Coil Replacement
Cooling and heating coils in AHUs, FAHUs, FCUs, and industrial systems degrade due to corrosion, scale, and wear. Damaged coils reduce airflow, cooling capacity, and energy efficiency.
We provide:
- On-site inspection and performance assessment
- Removal of damaged coils
- Installation of new factory built or custom fabricated coils
- Testing and commissioning for guaranteed performance
Why These Specialized Services Matter
- Prevent costly shutdowns
- Maintain safety and system integrity
- Extend equipment lifespan
- Improve HVAC performance and energy savings
- Reduce emergency repair risks
FAQ Section
Q. What is hot tapping in HVAC and industrial systems?
Hot tapping is the process of connecting a new branch to a live pipeline without shutting down or draining the system.
Q:Is pipe freezing safe for chilled water lines?
Yes. When performed by certified technicians, pipe freezing safely isolates sections of CHW pipelines by forming a controlled ice plug.
Q:How often should heat recovery wheels be serviced?
Typically every 6 to 12 months, depending on dust levels and operational hours.
Q:When should coils be replaced in an AHU or FCU?
Coils should be replaced when they are corroded, leaking, or no longer delivering proper cooling/heating performance.
Q: Do these maintenance services prevent system downtime?
Yes. Hot tapping and pipe freezing are specifically designed to avoid system shutdowns during maintenance work.
