0:09
plumbing and hvac technicians face in
0:11
the field we're your hosts from the
0:13
caleffi tech support team i'm greg tubbs
0:16
and i'm dan ferkus welcome we look
0:18
forward to sharing some stories from our
0:20
tech calls and using our background and
0:22
expertise to make your days a little
0:24
easier
0:26
[Music]
0:28
hey there welcome back to the ask luffy
0:31
podcast
0:34
how are we doing dan oh i'm doing good
0:36
today greg how are you doing not too
0:38
shabby oh
0:39
beautiful day today yeah a beautiful
0:42
rainy day
0:43
[Laughter]
0:45
here we are heating season yeah
0:47
definitely heating season temperatures
0:49
outside are going down we've got a lot
0:51
of rain today here in the milwaukee area
0:54
certainly do
0:55
and with the temperatures going down the
0:57
call volume has come up it sure has the
0:59
call volume has come way up yeah plenty
1:02
of questions being asked on how how to
1:05
install certain components into systems
1:08
and where to install them absolutely
1:10
wiring questions a lot of wiring
1:12
questions troubleshooting wiring
1:14
questions applications with manifolds
1:17
lots of ways it's been manifold day yeah
1:20
it's been manifold week it has
1:23
all right that's good we like the calls
1:25
yeah we want to hear from you we'd
1:26
rather hear from you while it's going on
1:29
versus after it's not working and been
1:31
installed then you're frustrated right
1:34
right yeah don't be afraid to reach out
1:36
please call us
1:37
so
1:38
we're going to talk about a relatively
1:40
new product not totally new but a new
1:42
twist on a nice product that we offer
1:45
yeah we sure are it's a product that
1:47
actually we were the pioneer into the
1:49
industry on
1:50
um and we've just taken it and made it
1:53
better yeah we certainly did we're
1:55
talking the dirt mag and in this case
1:58
the dirt mag pro yeah the dirt bike pro
2:01
so
2:02
what can you tell us about it i mean
2:04
what do you know what do you know what
2:06
do i know what do you know i don't know
2:08
a whole lot but i'll see what i can do
2:11
i know it's been a great product for us
2:13
there's a lot of excitement about it
2:15
what we did is we took our original
2:17
brass dirt mag
2:20
and we've added a second magnet to it
2:22
and that magnet drops in from the top
2:24
right down we redesigned the coalescing
2:26
mesh yep um and that magnet is in a well
2:29
and it drops right down through the
2:31
center of that coalescing mesh yeah
2:32
again dry well down through a dry well
2:35
exactly
2:36
so
2:37
it's going to do a great job of grabbing
2:39
that ferrous material and holding it
2:42
and then you pull the magnet to release
2:44
it so i mean it's it's got 40 percent
2:46
more power than what our original dirt
2:48
mag had and i'll tell you you and i have
2:50
been playing with that magnet and the
2:51
dry well in our lab and that thing's got
2:54
a lot of holding power yeah it's very
2:56
surprising how much it can grab and hold
2:58
up
3:00
right in the body itself
3:02
just
3:03
its ability to catch
3:04
more dirt or more ferrous material not
3:07
dirt more ferrous material
3:10
out of solution is pretty awesome yeah
3:14
yeah so i mean a lot of you might be
3:15
familiar with that original dirt mag the
3:17
dirt make pro is
3:19
newer and better
3:21
yeah yeah and i think you covered it i
3:23
mean redesign the coalescing mesh so
3:26
that dry well fits down in right in the
3:29
mainstream of the liquid
3:31
flowing through it
3:32
and
3:35
maintaining it is real easy right it
3:37
still has that clip-on magnet that that
3:39
you're used to seeing on our original
3:40
dirt mag so you've got two magnets
3:43
on that product sure
3:45
i had somebody ask us
3:47
or ask me over the phone the other day
3:49
you know how do i
3:51
what's what's the sequence of operation
3:53
on on doing a maintenance on one of
3:55
these
3:56
so well it's pretty simple i mean
3:58
step-by-step processes one you you want
4:01
no calls for heating the system or you
4:03
don't want pumps running right
4:05
keep the pressure on the system
4:07
but shut the pumps off
4:10
from there
4:11
get a bucket over there or get a hose
4:13
typically i would tell a guy use a
4:14
bucket over a hose even though we have
4:16
the garden hose thread connection on the
4:18
bottom we do a bucket's a little nicer
4:20
you can get you can see that flush
4:22
process uh as it's occurring and
4:25
and you'll know when right when to shut
4:26
it down right but
4:29
pretty simple you know no pumps running
4:31
pull the magnetic band remove the
4:34
magnet from the top just by pulling it
4:36
right out of the drywell right so
4:40
put your bucket underneath open and open
4:42
the purge valve purge it out until you
4:44
see clean liquid yeah i mean it might be
4:47
10 to 15 maybe 20 seconds depending on
4:49
how bad and full of that the debris it
4:51
is right yeah usually i say once you see
4:53
it flush clear for about 10 to 15
4:56
seconds you're good to close that valve
4:58
and reinsert the magnets yeah
5:00
reinserting the magnets is real
5:03
self-explanatory
5:04
you go through that and
5:06
turn the system back on you're back in
5:08
service again right and what's really
5:11
nice is
5:12
you don't have to be too careful to keep
5:14
your hands clean you know you sure don't
5:16
not like you know i've seen with some of
5:18
the other options out there in the in
5:19
the industry yeah
5:21
i can't believe how messy that is to try
5:24
and scrub that stuff off with a rag you
5:26
know with a shop rag or a towel to try
5:28
and get all that stuff off i mean these
5:30
are strong magnets it's really hard
5:32
you'd be fighting to get it off the
5:33
magnet oh yeah i mean we set up that
5:36
display with the magnet in it and we
5:38
actually have it inserted into a jar
5:41
with some steel shot bbs in it and when
5:44
you flip it over it's amazing it'll grab
5:46
all of those bbs and hold it right to
5:48
that drywall but as you're pulling that
5:50
magnet out of the drywall you see that
5:52
debris release yeah fall off down to the
5:55
bottom which would be right to your
5:57
purge point sure another thing i really
5:59
like about this like if there were large
6:02
pieces of debris you can actually take
6:05
this thing apart you can take the bottom
6:07
bell right off where that magnetic clip
6:09
is and it's got an o-ring seal you'll be
6:12
able to pull it off and pull the mesh
6:14
out and flush that if you had like large
6:16
chunks of
6:18
say some thread tape or something from
6:19
the system that got caught in there yeah
6:21
if you had really large debris in there
6:23
you might not get it to come out of that
6:25
purge point um so you're right you can
6:27
pull that out you can pull that
6:28
coalescing mesh right out of it clean it
6:30
out flush it out wash it put it right
6:32
back in
6:34
pretty easy to do actually right i think
6:37
another question that we get a lot of is
6:39
i only have so much room where
6:42
should i put a dirt mag where should i
6:45
put a dirt separator
6:46
well having one in your system is is key
6:50
right um generally i like to see it
6:52
right before the inlet of the boiler
6:54
same because now you're collecting any
6:56
debris and removing any debris before it
6:58
would enter your your boiler whether
7:00
it's high efficient or mid efficient
7:02
you're getting that debris out before it
7:03
can settle in the heat exchanger or
7:06
cause any damage to that piece of
7:07
equipment right um also you're going to
7:10
pull that ferrous material out because
7:12
that's going to also help protect your
7:14
variable speed pumps right remember your
7:16
system itself is a dirt separator it is
7:19
it's a giant dirt collector right it's a
7:22
big dirt collector so anywhere in your
7:25
system where you have a little bit of a
7:26
drop in velocity that dirt is going to
7:28
settle so it'll settle into radiators
7:30
you know panel radiators heat exchangers
7:32
of boilers
7:34
cast iron boilers the bottom sections
7:36
you know any kind of piping traps right
7:38
yep you get anywhere you're going to get
7:40
a velocity drop
7:41
that dirt is going to settle
7:43
and that's you know the big key with our
7:45
dirt separator is it's a large opening
7:47
in the pipe you know it's typically a
7:49
three to one connection size so the
7:51
body's three to one three sizes larger
7:53
than the connections so it creates that
7:55
instant velocity drop the magnets grab
7:58
that ferrous material the non-ferrous
8:00
material dropped to the bottom yeah and
8:02
you can purge it right there yeah it's
8:05
pretty pretty darn slick prevents it
8:07
from landing in the other parts of the
8:08
system where you really don't want it
8:10
yeah now
8:13
i've gotten the question about air dirt
8:15
separators
8:17
not to get too far off the topic but
8:20
a guy will get one
8:22
because
8:23
his primary focus maybe is
8:26
the fact that he wants to remove dirt
8:29
but
8:30
he sees that air vent on there and
8:31
that's kind of confusing isn't it
8:33
yeah well it
8:35
that that device provides both air ender
8:37
separation right magnetics right you
8:39
know it's going to do a great job of all
8:41
three
8:42
um but you're right where do we locate
8:44
that i mean that becomes becomes a key
8:46
factor because you know i have i've had
8:49
the call too you know hey i'm really
8:51
concerned i got an old system i want to
8:53
make sure that i clean it up and protect
8:55
my new boiler
8:57
so i bought the discal dirt meg
8:59
and great product but if you're putting
9:01
it in for dirt removal i like to see it
9:03
before the boiler but when you look at
9:05
air separation
9:07
your best location is going to be on the
9:09
supply side after the boiler where that
9:11
water temperature is the hottest exactly
9:13
and that's where you got to ask
9:15
we got to turn around and ask them hey
9:18
what do you really want to do here
9:20
right what is your prima primary
9:22
objective of installing this device is
9:25
it to remove dirt and an air is kind of
9:28
a secondary then we definitely can say
9:30
you know what it's got to go on the
9:31
return back into the boiler right
9:33
protect that boiler protect the pumps
9:36
yeah it's not going to be as efficient
9:37
in air separation no um it still is
9:40
because it has the coalescing mesh and
9:42
you know it's still going to remove air
9:44
but the water temperature is going to be
9:46
a little cooler than it would be on the
9:48
supply side right and by then too a lot
9:51
of the air is already getting trapped in
9:52
more of the high points of the system
9:54
right right well and he had
9:56
i know the one guy i talked to had a
9:57
auto air vent at the top side of the
9:59
boiler so sure you know he did have a
10:02
source of air removal there as well um
10:04
if it's a new system you know and you're
10:07
already starting relatively clean you
10:09
know then
10:10
you know in that application i would
10:12
probably put it on the supply side and i
10:15
generally tend to to lean towards the
10:18
supply side after the boiler
10:20
out coming out of the boiler with the
10:22
scale dirt meg for that air separation
10:25
sure but i certainly understand his
10:26
point when with focusing on dirt removal
10:30
and that application you know maybe a
10:31
little bit more cost a little bit more
10:33
piping i probably would have done one of
10:35
each and put the dirtmag pro right on
10:37
the inlet for the boiler and then our
10:41
our discal air separator on the outlet
10:43
yeah
10:44
that 551 series
10:46
or even gone to a full hydraulic
10:48
separator or sep4 yep exactly if they
10:51
haven't needed an idea that's always the
10:53
most ideal right but with with the
10:56
dirtmag pro i mean we're offering it in
10:59
one inch inch and a quarter inch and a
11:01
half and two inch sizes all the brass
11:04
bodies all brass bodies
11:06
they
11:07
are going to have
11:08
sweat press and npt connections right
11:11
flow rates the flow rates are pretty
11:13
generous i think i mean one inch you're
11:15
looking at 14 gallons a minute and up to
11:17
two inch the two inch is good for 54
11:19
gallons a minute so it covers a pretty
11:21
high flow rate yeah and that's at five
11:23
and a half feet per second right we have
11:25
plenty of options available in different
11:28
sizes and connection types so it's
11:30
really up to you if you are looking to
11:32
upgrade or add
11:35
something to remove ferrous material and
11:37
non-ferrous material dirt make pro is
11:39
where it's at right whether it's a new
11:41
install a new system installation or
11:43
retrofit and doing existing yeah and if
11:46
you need help sizing or selecting a
11:48
product you'll give us a call we're
11:50
happy to help you with that yeah that's
11:52
what we're here for and that's what we
11:54
want to continue to do yeah so we're
11:56
excited we're you know
11:58
you may have seen the dirt meg pro in a
12:00
lot of the trade magazines i know
12:02
more online i know we're doing a big
12:04
push to to get it out there
12:06
we're certainly excited about it and
12:08
just thought you know what we wanted to
12:09
take an opportunity if you hadn't had an
12:11
opportunity to grab one of those
12:13
publications or see it um to at least
12:16
announce it and tell you a little bit
12:17
more about it yeah so there you go you
12:19
got the meat and potatoes on the dirtmag
12:21
pro thanks for listening yep thanks guys
