1000 KVA DIESEL GENSETS FOR SEAWATER REVERSE OSMOSIS DESALINATION PLANT IN SAUDI ARABIA

Coelmo has supplied a generating set - model PDT408A2 Perkins engine 4008-TAG2A version with a Mecc Alte alternator model ECO43 VL4 A - to a desalination plant in Yanbu, Saudi Arabia, where it will provide backup power for a saltwater reverse osmosis plant.

The reverse osmosis process was chosen by the client company because of its potential for effective energy recovery compared to that of other seawater purification methods, but the process does require an uninterrupted power supply.

SWRO desalination plants like those found in the Kingdom of Saudi Arabia can achieve a 50% energy recovery with the utilisation of a two stage configuration with a single pass, operating at a maximum 82% horsepower (HP) pump efficiency for a capacity of 1000 GPM of permeate water.

In the recent genset contract, Coelmo was directly involved in the design, production, installation and commissioning of the 1,000 kVA Generating Set, 400V, 60 Hz 1800 rpm. Colemo has supplied this particular genset package with:

- A steel container 40-feet long, 85d(B) @1 m with anticorrosive paint suitable for particularly aggressive environments (C5M) such as those found in the heavy saline, coastal regions of the Gulf.

ECO43 VL4 A - TO A DESALINATION PLANT IN YANBU, SAUDI ARABIA, WHERE IT WILL PROVIDE BACKUP POWER FOR A SALTWATER REVERSE OSMOSIS PLANT.”

The genset was also supplied with an automatic control panel, an air conditioning system for the control panel compartment and an integrated fire extinguishing system with CO2 extinguishing in accordance with NFPA standards.

The genset’s engine is the 8-cylinder Perkins 4008 rmodel. According to the manufacturer the engine “gives you the versatility you need in today’s power generation market.”

The range’s diesel ElectropaK engines/Electro Units deliver 8491022 kVA and are supplied with or without radiator and air cleaner.

This engine has proven reliability in prime and standby installations in all of the key sectors, including manufacturing facilities, hospitals, and data centres.

Key specifications are:

*Gross Mechanical Output

644-997 kWm

*Typical Electrical Output: 720-1125 kVA (576-900 kWe)

*Emissions - Fuel Optimised

The 4008 engines are said to have exceptional power-to-weight ratios and compact designs, making them simple to transport and install.

The 4008TAG2A is a turbo-charged, air-to-air charge cooled, 8-cylinder in-line diesel engine.

Typically it is provided with either Temperate or Tropical cooling packages (with or without fuel cooling).

Their premium design and specification features provide economic and durable operation as well as exceptional power-to-weight ratio, improved serviceability, low gaseous emissions, overall performance and reliability essential to the power generation market.

4008-TAG2A engine benefits

The individual four-valve-per-cylinder heads give optimised gas flows, whilst digitally governed unit fuel injectors ensure ultra fine fuel atomisation and hence controlled rapid combustion, for efficiency and economy

Another key design feature is commonality of components with other engines in the 4000 Series family - this allows reduced parts stocking levels.

Developed and tested using latest engineering techniques, in the 4008-TAG2A model the piston temperatures are controlled by an advanced gallery jet cooling system. All engines are designed to tolerate a wide range of temperatures without derate.

A spokesman commented: “There is an exceptional power-to-weight ratio and it has a compact size for easier transportation and installation.

“There are also newly- designed radiator assemblies with corrosioninhibiting powder coated surfaces; fewer pipe joints and easier access to reduce maintenance times. The engines are designed to comply with major international standards - and there are low gaseous emissions for cleaner operation.”

Lastly, the 4008-TAG2A has been designed to provide excellent service access for ease of maintenance. This maintenance service can be provided by an extensive network of over 4,000 distributors and dealers worldwide

Optional features for this model include:

• Tropical radiator, including water pipes, clips and hoses, fan, fan guards and bolts

• Twin heavy-duty air cleaners –paper element with pre-cleaner

• Changeover lubrication oil filter

• Changeover fuel oil filter

• Immersion heater with thermostat

• Air starters
