My name is Magnus Hedberg, and I’ve been
leading development for FlexFlow™
00:00:12.120 --> 00:00:15.560
for gasketed plate heat exchangers at Alfa Laval.
00:00:15.640 --> 00:00:22.920
We have made a completely new plate here with a new
type of gasket and a new type of gasket groove.
00:00:23.000 --> 00:00:27.920
We have also changed the heat transfer area to
make asymmetrical configurations possible
00:00:28.040 --> 00:00:34.160
and still have the pressure performance of
a symmetrical plate configuration.
00:00:34.600 --> 00:00:40.040
Heat transfer area isn’t always the
limiting factor for a heat exchanger.
00:00:40.120 --> 00:00:42.320
Sometimes it could be the pressure drop.
00:00:42.400 --> 00:00:48.240
With symmetrical configurations, you’re able to create
three channels with two different plates.
00:00:48.360 --> 00:00:54.760
But with this new design, we are able to create ten
different channels with the same number of plates.
00:00:54.880 --> 00:01:00.240
The big advantage with this new type of
plate is the flexibility.
00:01:00.320 --> 00:01:06.520
You are able to find a much better thermal fit
than with previous plate patterns.
00:01:06.640 --> 00:01:12.400
This will lead to a smaller unit, a lighter unit and
a smaller footprint for the customer.
00:01:12.560 --> 00:01:16.520
This is a much more cost-efficient
product in terms of lifecycle.
00:01:16.600 --> 00:01:21.600
The unit’s thermal performance will increase
substantially with these new plates.
00:01:21.760 --> 00:01:30.960
It’s easier to service the unit. There will be less
re-gasketing, cleaning of the plates will be easier
00:01:31.040 --> 00:01:35.280
and the lifecycle cost for the unit will be lower.
00:01:35.360 --> 00:01:39.040
At Alfa Laval, we’re always striving
to make a better product.
00:01:39.160 --> 00:01:42.800
It is important for me as a development
engineer and as a designer
00:01:42.880 --> 00:01:46.640
to come up with a better solution
than we previously had.
00:01:46.720 --> 00:01:51.240
The main goal here is to find the
thermal fit as good as possible.
00:01:51.360 --> 00:01:58.880
And by having these ten channels, with two plates,
it is possible to get a much better pinpoint of the solution.
00:01:59.000 --> 00:02:04.600
This will help Alfa Laval support customer
duties even more than we do today.
