feeling sorry for the Blackbird out
00:00:35.640 00:00:35.650 there in the winter chill lonely and
00:00:39.060 00:00:39.070 lovesick and with its feet in the
00:00:40.889 00:00:40.899 ice-cold snow don't worry the cold never
00:00:45.930 00:00:45.940 reaches its body for this the bird can
00:00:50.759 00:00:50.769 thank the ingenious heat transfer system
00:00:53.099 00:00:53.109 in its legs cold blood from the feet is
00:00:56.700 00:00:56.710 heated by warm blood from the body the
00:01:00.840 00:01:00.850 heat is transferred through the thin
00:01:02.819 00:01:02.829 walls of the veins the same natural
00:01:06.210 00:01:06.220 process forms the basic principle of
00:01:08.609 00:01:08.619 alpha levels heat exchangers they
00:01:12.030 00:01:12.040 consist of a large number of thin metal
00:01:13.980 00:01:13.990 plates tightly pressed together in a
00:01:16.530 00:01:16.540 frame between the plates are channels
00:01:19.770 00:01:19.780 through which liquids pass the hot
00:01:23.460 00:01:23.470 liquid heats up the cold liquid when the
00:01:26.249 00:01:26.259 heat is transferred far the thin metal
00:01:28.139 00:01:28.149 walls more plates give a larger transfer
00:01:31.740 00:01:31.750 surface which in turn means greater
00:01:34.889 00:01:34.899 energy efficiency Alfa Laval heat
00:01:38.310 00:01:38.320 exchangers play a key role in for
00:01:40.469 00:01:40.479 instance oil refineries power generation
00:01:43.649 00:01:43.659 and a vital components in district
00:01:46.560 00:01:46.570 cooling and heating systems plate heat
00:01:50.190 00:01:50.200 exchanges deliver heating and cooling to
00:01:52.889 00:01:52.899 homes and workplaces in many parts of
00:01:55.469 00:01:55.479 the world there are almost
00:01:59.130 00:01:59.140 one-and-a-half million different animal
00:02:01.440 00:02:01.450 species on our planet many have
00:02:04.560 00:02:04.570 developed processors similar to those we
00:02:06.660 00:02:06.670 use in industry and in our daily lives
00:02:10.430 00:02:10.440 take separating the usable from the
00:02:13.229 00:02:13.239 unusable for example we peel onions and
00:02:16.990 00:02:17.000 potatoes we cut the green tops of
00:02:19.510 00:02:19.520 carrots and we fill it fish just like
00:02:23.800 00:02:23.810 the mashed crab which uses the small
00:02:25.960 00:02:25.970 hairs at the ends of its legs to filter
00:02:28.300 00:02:28.310 out clean water from the swamp sludge
00:02:31.830 00:02:31.840 separation is all about separating
00:02:34.180 00:02:34.190 various liquids gases and particles from
00:02:37.090 00:02:37.100 each other the principle is simple the
00:02:41.590 00:02:41.600 liquid with the highest density is
00:02:43.330 00:02:43.340 separated naturally from the other
00:02:45.160 00:02:45.170 liquid when it sinks to the bottom by
00:02:48.970 00:02:48.980 rotating the mixture rather like what
00:02:51.070 00:02:51.080 happens in a washing machine centrifugal
00:02:54.010 00:02:54.020 force can be used to speed up the
00:02:55.870 00:02:55.880 process in the same way as the marsh
00:03:00.729 00:03:00.739 crab separates the usable from the
00:03:02.680 00:03:02.690 unusable Alfa Laval separation
00:03:05.620 00:03:05.630 technology is used to clean oil in the
00:03:08.199 00:03:08.209 engine rooms of large cargo ships as
00:03:10.530 00:03:10.540 well as in the production of olive oil
00:03:13.210 00:03:13.220 and to turn wastewater into pure water
00:03:21.060 00:03:21.070 water is the basis of all life but in
00:03:26.020 00:03:26.030 certain waters some of the world's most
00:03:28.240 00:03:28.250 dangerous creatures are to be found it
00:03:32.770 00:03:32.780 attacks and holds its prey beneath the
00:03:35.740 00:03:35.750 surface until it drowns the crocodile is
00:03:39.430 00:03:39.440 a magnificent swimmer and the saltwater
00:03:42.039 00:03:42.049 crocodile can grow to 7 metres long and
00:03:44.770 00:03:44.780 weigh more than a ton when the crocodile
00:03:49.030 00:03:49.040 is underwater and cannot get oxygen to
00:03:51.970 00:03:51.980 its lungs an ingenious heart valve kicks
00:03:54.970 00:03:54.980 in the valve shuts off the supply of
00:03:58.569 00:03:58.579 blood to the lungs and redirects it out
00:04:01.930 00:04:01.940 to the muscles which absorb the oxygen
00:04:05.430 00:04:05.440 this way the crocodile can remain
00:04:08.020 00:04:08.030 underwater for more than an hour
00:04:11.450 00:04:11.460 a mechanical valve functions in the same
00:04:14.330 00:04:14.340 way as the crocodiles heart valve it
00:04:17.150 00:04:17.160 shuts off or redirects the flow
00:04:20.890 00:04:20.900 alpha levels unique valves make it
00:04:23.690 00:04:23.700 possible to handle two liquids at once
00:04:25.700 00:04:25.710 in the same valve without the liquids
00:04:28.940 00:04:28.950 coming into contact with each other
00:04:31.570 00:04:31.580 thus it's possible to create flow
00:04:34.130 00:04:34.140 systems where cleaning and production
00:04:36.530 00:04:36.540 take place in parallel Alfa Laval fluid
00:04:41.120 00:04:41.130 handling products fulfill an important
00:04:43.340 00:04:43.350 function in for instance the production
00:04:45.620 00:04:45.630 of mozzarella cheese in the
00:04:47.630 00:04:47.640 pharmaceutical industry and in the
00:04:49.910 00:04:49.920 production of various fruit juice
00:04:51.560 00:04:51.570 concentrates Alfa Laval continuously
00:05:12.890 00:05:12.900 develops new products to meet customers
00:05:15.530 00:05:15.540 needs and wishes
00:05:16.850 00:05:16.860 each product is based on innovative
00:05:19.730 00:05:19.740 technology yet still with obvious
00:05:23.210 00:05:23.220 similarities to processes we meet in
00:05:25.610 00:05:25.620 nature
