00:00:07.320 --> 00:00:12.040 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.
