Generator On Standby Remote Cooling System

Generator on Standby for Remote Cooling System

Concerning This Project
A data centre in the United Kingdom contacted us. They had performed some tests on their current cooling system and sent us some data in order to manufacture a completely new heat exchanger to cool their standby generator.

Background Information on the Project
The heat exchanger's purpose was to cool jacket water and charge air cooler water inside a remote container. It had to be a free-standing (frame-mounted) double radiator with fan-assisted cooling that was vented to the outside of the container. In order to fit in a remote-based container, the finished unit had to be a specific size.

The following was the specification provided to us:
(2000kVA / 1600kWe Prime) (2200kVA / 1760kWe Standby) Radiator Diesel generator with a 400v/50Hz rating.
The engine is a Mitsubishi S16R-F1PTAW2 diesel engine with a Leroy Somer LSA52.3-S6 alternator.
The radiator will be horizontal (electrically powered) and will fit inside a 40ft container (flush fitting in the roof) and will be rated at 80dBA @ 1mtr.

What Did We Do?
We created a 3D mockup of the unit after our quote was accepted, using specialist software that we use to design our units. After these drawings were approved, the manufacturing process began.

We make all of our own parts, including the following:

Our in-house fin line production machine produces aluminium fins.
Tube plates produced on a CNC machine
Steel framework created by laser cutting and CNC folding of copper tubes
After that, the individual parts were assembled and pressure tested to a predetermined pressure.

Outcome
We delivered the finished units to the client ahead of the deadline. The units were then installed by the client and are now in place and functioning as expected.
