Maintenance and repairs SOP

Water cooling
systems maintenance
Regular maintenance of the water cooling system helps the system operate properly and continuously while maintaining high energy efficiency. Our service team consists of experienced service technicians with proven knowledge and experience in performing maintenance treatments for water cooling systems. The service consists of 3 main steps that are performed in each visit.
Compressor check
The compressor in the chiller is responsible for pumping the coolant along the system by using variable pressure to cool the pipes. Proper maintenance of the chiller compressor includes:
- Check the pressure and temperature of the pumping operation.
- Checking pressure and temperature in the system output.
- cooling liquid level check
- Electricity check
- Evaporator check
Evaporator check
The evaporator is responsible for absorbing the heat from the work process or structure (depending on the type of chiller). Proper maintenance of evaporator includes:
- Intake pressure test
- Outlet pressure test
- Insulation and pipeline check
Compressor check
The condenser is the component responsible for removing the heat that comes from the compressor, proper maintenance of the chiller condenser includes:
- Engine test
- Copper coil check
- Intake and Outtake temperature check
In addition, comprehensive tests are conducted for the detection of coolant and pressure in the pipeline, as well as treatment of the cooling fluid and measurement of its quality by chemical testing of pollutants and lime-scale that may cause clogged pipes.

VRF maintenance
service
VRF systems are the peak technology for customized air conditioning solution. Like any air conditioning system, VRF air conditioner also requires care and maintenance so you can continue to enjoy superior performance and low energy consumption. In addition to VRF installation services, we also provides maintenance services for VRF air conditioners by our expert technician teams.
Maintenance service for VRF includes:
Complete cleaning of all evaporators including thoroughly cleaning of filters and use of mold prevention material, cleaning of drainage channels, cleaning of accelerators and evaporator coils, checking electrical connections and checking temperature in cooling and heating operation mode.
Checking compressors BTU output and gas pressure in the condenser, cleaning and rinsing of the coils of the condenser and checking the electrical voltage and correctness of the fan.

Dedicated HVAC
maintenance
Communications and servers rooms are the engine behind a modern business and while most resources are directed to server and hardware maintenance, rooms that are not properly cooled can cause servers to crash under the heat load generated in the information processing process. Proper maintenance of cooling systems designated for computer rooms enables the equipment to operate at maximum capacity and to provide users with continuous activity without downtime.
Computer rooms are dynamic and constantly changing, whether with the addition of computer cabinets or upgrading of hardware components, therefore it is necessary at all times to measure heat loads and cooling system durability throughout the hours of operation. Our company provides maintenance services for dedicated air conditioning systems for server farms and computer rooms by a team of expert and experienced technicians in the operation, upgrading and maintenance of dedicated air conditioning and cooling systems.
