Joven water heater cost at RM240! 

Monsoon season very cold. That is why we need

to use it..... 

Foxboro Malaysia Products

There are no Foxboro Malaysia Products (instrumentation)

install in hydro plant that I work. Most equipment 

for instrumentation in hydro plant using OEM

parts which is seldom we see and it is so 

difficult to change or to find the equivalent

parts. 

Foxboro Malaysia has a lot of products which 

are using in thermal plant. Most equipment that we can see

such gauge, valve, transmitter, thermocouple 

and many more.

How much you pay for this Iphone 5s charger cabel? Not original one!

I spent RM20 since I forgot to bring together during my outstation.

Rail Mounted Terminal Block Wago

Terminal block Wago was already in market for more than 60 years. Have heard about this terminal block before?

Usually we are using screw type of terminal block. But since 1951, Wago put into practice the idea of using spring pressure instead of screw to connect electrical. 

Truflo Valves Limited

In a blowdown system, there are few critical valves exist. Usually ball valve and needle valve have been used. One of the repo valve used in hydro station is Truflo Valves Limited. 

Are this OEM player still exist in the hydro power plant industry? As I noticed it is quite difficult to find whether to purchase complete set of valve or their parts. 

Do you have facing same problem with this OEM in terms of their support or parts to purchase?

Bataan Philippines Nuclear Power Plant

Bataan Nuclear Power Plant is a nuclear power plant. It is completed 1979 but never been fueled.

It is located 100 km west of Manila Philippines. This plant has not commission due to some issues such: 

1) It was build just near major earth quake fault line and close to Mount Pinatubo

2) Lots of defects revealed (4000 defects exist) 

The cost to build up reached $US2.3 billion. The Bataan Nuclear Power is designed to generate 621 MW of electricity. 

Plant Rehab

Meaning: therapy or treatment to the plant and do improving on the machine such upgrading and uprating. 

What is the lifespan of a heat exchanger?

What is lifespan of a heat exchanger in your plant?

I believed a good brand/manufacturer of a plate heat exchanger and apply good maintenance will make it life last longer at least more than 10 years right?

How much it cost? My experience said it will taken 1/3 from initial cost of a new heat exchanger. To me it is acceptable since you have you use it for more than 10 years!

This Brush Pas Model 510 has been obsolete long long time ago and no longer in production line. This including their support service which is not exist already. 

The function of auto synchronizer in plant is to synchronize generator output to the grid system. 

Parameter in used;

Voltage, frequency, phase angle and phase sequence. 

Brush Autosynchronizer

Auto synchronizer provide precise synchronization of generator (s) to a power system.

BRUSH is one of the models in the market for auto sync. Anyway the parts, warranty, system support from them is no more exist?! The production of this model has been stopped and no more produce including support on the system itself. 

Need to find new solution and there are a lots in market on this synchronizer.
