Iwaki MX 100 final analysis

[roidan]

The mystery clouding over the sticker is solved.

[roidan]

confirmed by my digital clamp meter

0.95A x 240V

= 228W

YIPEE!!!! my mx100 draws 228W only

[lightningstrike]

bro, only differs by 12W from the originally rated 240W.

[roidan]

bro, only differs 12W from the original rated 240W.

u missing the point by a very long mile ah...

coz some thought it is drawing 375W mah!

[roidan]

today's findings confirmed the graph that weileong posted some time back...

that yes, at peak wattage, both mx100 and mx70 will draw the same wattage...

but for the same flow rate, the mx70 does draw slightly less wattage than the mx100, although the mx100 can push the same amount of water at a slightly greater height

say my current application of the mx100 draws 228W....if i just swap the pump to a mx70...probably the mx70 would draw around 200W or so......

but yes....luckily singapore is running on 50Hz

no 60Hz mx100 drawing 375W please

[lightningstrike]

u missing the point by a very long mile ah...

coz some thought it is drawing 375W mah!

hehe....... sorie sorie. but thought we shld be looking at 50Hz which equates to 240W from the specs on the pump.

[roidan]

but alot of people did not believe how come at 50Hz it was drawing 240W whereas at 60Hz it was drawing 375W..

[roidan]

look at the hon's ex mx70..

it draws 250W at 50Hz and 375W at 60Hz...

now u know why so much questions over the mx70 and mx100 in the past.....end up mx70 and mx100 draw about the same but the mx100 offers more flow

everyone thought mx70 drew 250W at 50Hz and thus for mx100 to draw 240W at 50Hz, it must be a misprint....but no, the sticker is correct...hehehe

MX100 rocks....join the centenary club of the 100s

[weileong]

gotta take into account the power factor too so I think 240W is correct liao... wow heng not 375W else you go broke running it

I think time to upgrade to MX100.

[roidan]

now running 2 mx100s already broke....

look at my bill, nothing compared to landed property owners lah....but quite considerable for a HDB user i think

bullish market for electricity....bearish for water

[yazid]

Wow! I thought my electricity consumption at 1050 per month was bad already.

[lightningstrike]

bro, 2269kwh for the mth of Nov??? that's abt S$375.

[yazid]

His Nov bill is 455.31!!!

Anyone higher than this? Come on don't be shy?

I wonder if AT can beat Roidan bill..

[lightningstrike]

His Nov bill is 455.31!!!

Anyone higher than this? Come on don't be shy?

I wonder if AT can beat Roidan bill..

yazid, how u get $455.31 har? i juz multiplied 2269 by $0.1653/kwh. never add gst and other stuff.

[yazid]

I said his Nov total bill as indicated is $455.31. It is on the top right corner of his bill.

[lightningstrike]

I said his Nov total bill as indicated is $455.31. It is on the top right corner of his bill.

icic, that's the total for water and electricity consumption.

[roidan]

I think AT at his peak consumption should be able to beat mine easily....i am only using 150Watters for lights

[yazid]

my bill is only $245 with heavy usage of electricity, water and gas.

[roidan]

somemore i not running the full iwaki lineup as planned...

the full line up should be using 2 mx100s for my skimmer......and 1 mx100 for returns/miscellanous...

now i am only using 1 mx100 for dual beckett application in my quattro and 1 mx100 for returns/miscellanous

lol...

if really use 2mx100s for my quattro = 480W skimmer...LOL

but ok lah..quite happy with the single mx100 pushing through 2 injectors so far....otherwise really break $500 electric bill mark soon

[typrobin]

I think AT at his peak consumption should be able to beat mine easily....i am only using 150Watters for lights

luckily his 1600W is only switched on for a few hours a day..unlike your 24/7 iwakis..

roidan, u are the maddest of them all!!!

my mom already screaming when the electrical bills increase by $30 due to my small tank...

[roidan]

anyway, to use 1 mx 100 of 240W to run my quattro, personally i feel it is quite efficient from my point of view....

coz going by wattage per litre of skimming volume,

mine works out to be about

240W/130litres

=1.846 W/litre

quite good already...

I am using the wattage that I am running now on the skimmer divided by the absolute water volume in the skimmer....and yes....i have 130 litres of water in my quattro....you need 86 bottles of 1.5litre soft drink bottles to fill up my quattro

if i run the full quattro operation, it will be

480W/ 130litres

=3.692W / litre

that will be a little too high for my personal preference at this moment

[roidan]

i compared with my previous H&S needlewheel

150-F2001 using only 38W...yes...ONLY 38W hor..

but...the volume of water in the skimmer is only around 12litres...around the red region in the picture below..agar agar lah..but u will get my drift..hehe

using 38W to work on 12litres of water gets me

38W/ 12 litres

=3.167 W/litre

compared to my 1.846 W/litre currently.....in other words when u take into context the volume of water, my beckett using mx100 is actually much more efficient than my previous H&S needlewheel..

strange? but true

[weileong]

Here's what I am getting from my MX70. The reading varies between 0.69A to 0.72A.

That's about 172W. The power consumption will depends on the actual load too.

[roidan]

ya....thats why according to the graph....wattage drawn will vary according to application...but the both pumps will reach their peaks of around 240W and 250W....so peak wattage is about the same...

just that under different loading situations, actual wattage drawn differs

[roidan]

in other words....the red line is the situation that weileong is subjecting his mx70 under.....it draws around 172W and gives the red line characteristics

for my mx100 application, it is near peak at 228W with the blue line characteristics

hope it is simple enough
