Hi all,

I'm planning to purchase a snacks frying machine but I am not very sure about this machine's performance in terms of the electricity required.

As the seller gave me the information below, may I know if I put this machine inside a shoplot, will it overpowered?

This should not be something plug and use right? Sorry I'm not very sure about this.

What kind of additional work I need to perform before turning on this machine based on the Voltage and Power required.

Kindly please help

i suggest you look for another machine.

malaysia single phase is 240v, 3 phase is 415 volt. at 60hz.

Actually this is very rare machine as the performance is very different.. i looked more than about 30 + different machine.. this is one that most suitable huhu

ask seller to change the motor to AC415v

u use 380v u will have high amp heat problem

i see i see , i try ask the ssupplier

if change the motor, will it affect any heating issue?

Most probably NO.

Design margin of ±10% of 415 is compromised

380v ±10% is still within 415v no?

sorry i dont understand huhu
i'm not very good in voltage stuff.

Anything can be changed in order to be able to use?

will update another picture here that is sent by supplier

TS if u die die want to use that equipment with peace of mind maybe consider get a 3 Phase 415v to 380v step down transformer to use with it.

Assuming TNB supply is nominally ±10% of 415V. Max supply voltage is 460V, whereas equipment max voltage could be just 418V, the insulation may fail above 418.

Check insulation ratings in terms of voltage, conductor ratings in terms of normal current.

Shoplot is usually 60A 415V three phase supply. This machine alone will take up 60A. You need to upgrade the shoplot power to at least 100A.

For a heater the voltage difference of 380V and 415V is not critical. It will probably work. You can also get a transformer manufacturer to custom make a 415V to 380V step down transformer but it is probably unnecessary.

So the main thing to do is to get the shoplot owner to upgrade the TNB supply to 100A 3 ph.

ohh. .i see
so basically i need to speak to the owner regarding this issue?

because the difference between Electrical machine and GAS , GAS Machine is very very expensive compare to electric..

89 amps at full power.

If 3 phase at 60amp can supply actually 180 amps assuming the load is balance.

380volt Ac not suitable for our 3 phase electric.

In peninsular Malaysia TNB gives supply at 400/230V (+10%,-6%) at 50 Hz.
Your machine should work fine.
Like what KennyKB recommended, your machine will use >60A, so make sure you have at least 100A 3 phase from TNB at the very least.

Hi TS,

1) Inform the supplier that the voltage here is 400V, 50Hz. As them if their machine can take this. Mostly likely ok based on my experience.

2) The heater is 36kW, which means more than 50A is required. This is actually quite high for a normal shoplot, considering you have other appliances like aircon, water heater, etc. This will required proper wiring system and protection device, not just simply plug and play.

Suggest you consult an electrician on this.

but need to bear in mind, the running cost for electrical unit is much higher than gas system

ask the supplier to calculate the running cost for both, based on the local electrical and gas unit price

I dont know if this is true.. maybe in 1phase.. maybe..

I don't think this will work with your shop lot. Most shop lots only have 415V, 60A at most. Some even still have 240V incoming.

Better get your electrician to give his opinion. He will be able to tell how much kVA TNB allows for your shop. Do not attempt to install the circuit breakers urself.

My guess is the equipment u just bought was designed for factory use.

380v^2/36000w = 4.01 ohm.

94amps.

36kW is for commerical use.
High volume of fry like factory.

Gas fired.
Gas consumption around 3kg/hour.
