Care for your facilities before they stop.
Boiler room, boiler & industrial burner maintenance
Engineering, troubleshooting, repair and commissioning for mechanical and thermal facilities. We work with facility managers in hotels, hospitals, residential and commercial complexes, and industrial operations to define practical repair and maintenance scopes.
Mechanical facility services
Equipment must be assessed within its operating system. A boiler fault, for example, may involve the burner, water circuit or controls rather than the boiler alone.

Boiler room repair & maintenance
Diagnosis of interconnected heating, circulation and control equipment in building plant rooms. Service planning considers access, operating load and the permitted shutdown window.
- Boilers, circulation pumps and heat exchangers
- Expansion vessels, water softeners, valves and pipework
- Leaks, pressure fluctuations and control sequence faults

Hot-water, steam & thermal-oil boilers
Inspect boiler performance in relation to temperature, pressure, fluid condition and connected equipment. The repair scope is defined after reviewing the equipment model and site conditions.
- Feed systems, pumps and accessible connections
- Level, pressure and temperature controls
- Restart checks and maintenance planning after repair

Industrial burner repair & servicing
Troubleshooting gas, oil and dual-fuel burners through ignition sequence, flame stability and the relationship between burner output and boiler demand.
- Ignition electrodes and flame supervision
- Fuel valves, gas trains, fans and controls
- Combustion adjustment using suitable instruments

Hotel & hospital industrial laundry
Technical support for industrial washers, dryers, presses and ironing equipment, including the steam, water, power and drainage systems they depend on.
- Vibration, leaks, cycle faults and drying performance
- Steam supply and thermal system interfaces
- Planned servicing coordinated with laundry operations

Mechanical engineering & plant upgrades
Concept design, equipment selection and plant-room improvements based on actual load, available space and maintenance access. Energy-saving outcomes require site measurements, not generic promises.
- Thermal and hydraulic sizing
- Equipment layout, pipe routing and service access
- Controls coordination and commissioning requirements

Pumps & heat exchangers
Investigate circulation and heat-transfer problems before replacing equipment. Scaling, trapped air, flow imbalance and control faults can produce similar symptoms.
- Pump vibration, seals and operating condition
- Heat-transfer performance and pressure drop
- Expansion vessels and associated water-treatment equipment

Water features & jacuzzi systems
Mechanical support for circulation, filtration and water heating. The assessment considers pump selection, suction and return routes, temperature control and equipment access.
- Circulation pumps, filters and valves
- Heat exchangers, heating controls and leaks
- Electrical proximity to water and suction safety considerations
Preventive maintenance with a defined scope
A useful maintenance programme reflects operating hours, critical equipment and the site’s ability to stop a system. Monthly, seasonal or annual proposals can be discussed after the equipment and workload are reviewed.
- Asset review and recurring inspection checklists
- Seasonal service aligned with operating demand
- Temperature, pressure and equipment-behaviour monitoring
- Fault reports, corrective recommendations and agreed follow-up

Support shaped around your facility
Hotels
Coordinate hot-water and laundry servicing with occupancy, demand and practical access windows.
Hospitals
Define sensitive systems and shutdown limits with the facility team. Technical service does not replace infection-control or hygiene approval.
Commercial complexes
Plan maintenance around trading hours, public access and the ability to isolate parts of a circuit.
Residential complexes
Investigate uneven heating and hot-water interruptions with building management and coordinate temporary shutdowns.
Industrial facilities
Assess process heat, steam or thermal-oil demand and align repairs with production shutdown windows.
From assessment to agreed technical work
- 01
Describe the facility
Send the city, facility type, equipment nameplate, symptoms and available shutdown window.
- 02
Assess the equipment
Review the equipment and connected circuits to identify likely fault paths and the information needed for a site visit.
- 03
Agree the scope
Confirm proposed work, parts requirements, execution arrangements and cost before work begins.
- 04
Repair, test & document
Carry out the agreed work, check operating behaviour and record remaining issues and maintenance recommendations.
Before you request service
Which locations can be considered?
Isfahan is the current primary market. Requests for Tehran, Shiraz and other cities are reviewed against project scope and execution capacity. A listed city does not imply a local branch or guaranteed dispatch.
Can you service Packman or Riello equipment?
Common brands, including Packman and Riello, may be supported where the relevant model can be serviced and parts are available or can be sourced. No official dealership or manufacturer authorization is claimed.
What if a burner keeps locking out?
Do not repeatedly reset the burner or bypass flame, fuel or boiler protections. Follow the facility’s safety procedure and arrange assessment by a qualified person before continued operation.
Discuss your equipment and service requirements
Share equipment photos, nameplate details, fault history and site constraints. These inputs help define the next assessment step; a final diagnosis and price require the relevant technical review.
Service availability is confirmed for each project. Detailed service pages linked here are currently in Persian.
Household appliance repair
Washing machine, dishwasher and espresso machine repair remains available as a separate service line, including washing machine bearing replacement.
