New ABB Catalog Details Temperature Instrumentation
 "Temperature Catalog: Sensors, Thermowells and Transmitters," is the new 80-page catalog that covers sensors, thermowells and transmitters available from ABB Instrumentation. The calalog opens by noting that ABB offers a wide range of high quality RTD and thermocouple sensor assemblies with and without thermowells, plus a series of world class temperature transmitters. Sanitary sensors are available with and without thermowells and are built from standardized components.
The catalog divides into 11 sections, covering sensor assemblies with and without thermowells, high temperature sensors, transmitters, thermowells, connection heads and custom designs. Temperature transmitters come in head, field and rail mounts. The catalog offers detailed dimensions, schematics and ordering information for the many varieties and models available.
Thermacore to Develop Active Heat Sink Technology
Thermacore, Inc. has been awarded a $9.5 million contract, if all options are exercised, by the Defense Advanced Research Projects Agency (DARPA) for the development of Micro-technologies for Air-Cooled Exchangers (MACE). The successful development of this technology will significantly improve the thermal performance of military electronic systems such as telecommunications, active sensing and imaging, radar and other platforms. The goal of the MACE program is the development and demonstration of micro-technologies that will enable thermal performance improvements and reduce electrical consumption of air-cooled heat exchangers. The MACE program is a two-phase effort designed to run 48 months through the fourth quarter of 2013.
To support this development effort, Thermacore assembled a team of academic and industrial partners that will each bring their technology and platform experience to bear on the proposed solution. Thermacore will coordinate these efforts and attempt to move these technologies into an "applied product" to support the current and future needs of the US Military.
Alfa Laval Strengthens Presence in South Korea, Acquires Local System Builder
Alfa Laval, a company focused on heat transfer, centrifugal separation and fluid handling, has acquired Onnuri Industrial Machinery Co., Ltd., a South Korean system provider to the shipbuilding and diesel power markets.
“By acquiring Onnuri, we increase our local presence which makes us even more fit to meet demands from the important Asian shipbuilding and engine builder markets,” said Lars Renström, President and CEO of the Alfa Laval Group.
Nextreme Controls Polymerase Chain Reaction Process with Microscopic Peltier Heat Pump
Nextreme Thermal Solutions, a company focused on microscale thermal and power management products for the electronics industry, has demonstrated the application of thin-film thermoelectric devices for temperature control of the polymerase chain reaction (PCR) process used for DNA amplification. The microscopic size and millisecond response time of Nextreme's thin-film eTEC thermoelectric modules enable significantly shorter throughput times for DNA sequencing equipment. DNA replication represents one of several applications of Nextreme's product line for the test and measurement and healthcare industries.
Nextreme has successfully demonstrated short cycle time temperature control using two eTEC UPF40 thermoelectric modules that perform as microscopic heat pumps. The module uses the thermoelectric effect to heat or cool objects simply by changing the direction of current flow. A UPF40 module can pump a heat flux up to 80 W/cm2 at 25°C and is extremely thin, with a 0.650 mm profile and a small 2.5 mm by 5.1 mm footprint. Customers can expect 4.1 watts of cooling and heating from a Nextreme device with less than a 2 msec response time at the device level. In the micro-PCR application, where Nextreme was heating and cooling a plastic vial with water in it, this translated into an ability to heat the water up to 90°C in 15 seconds and cool it back down to 55°C in under 10 seconds.
PCR is a technique widely used in molecular biology to produce millions of copies of a specific DNA sequence in a short period of time. PCR-based testing is used in the diagnosis of hereditary diseases; the identification of genetic fingerprints (used in forensic sciences and paternity testing); and the detection and diagnosis of infectious diseases. The vast majority of PCR methods use thermal cycling, i.e., alternately heating and cooling of the DNA sample based on a predefined series of temperature steps.
A thermal cycler is an automated instrument specifically designed for this purpose. A typical device consists of a metal block with holes where plastic vials holding the PCR reaction mixtures are inserted. The instrument has an integrated heating/cooling unit that is used to systematically raise and lower the temperature of the block. Due to their low mass, Nextreme's thermoelectric devices are particularly well suited to achieve fast temperature changes while also achieving a uniform temperature distribution throughout the block. In addition, the microscopic size of the Nextreme eTEC enables different temperatures in different parts of the block - something that cannot be achieved with conventional technology. This is particularly useful when testing suitable annealing temperatures for primers, which are required for initiation of the DNA replication sequence.
IBM Technology Licensed by Vette Receives Patent Approval
Vette Corp., an IBM Business Partner and global provider of thermal management solutions, has announced that IBM was awarded a patent by the US Patent Office for the Cool Blue Rear Door Heat Exchanger. In 2007, Vette began working with IBM to license the chilled water Rear Door Heat Exchanger technology. Vette manufactures Rear Door Heat Exchangers to fit the IBM NetBAY42 Enterprise Rack, the IBM 42U S2 Standard Rack and for a variety of leading thirdparty equipment enclosures. In addition to manufacturing Rear Door Heat Exchangers, Vette provides turnkey datacom facility cooling solutions, installation and support services.
IBM's Rear Door Heat Exchanger is a passive, water-cooled door that mounts to the back of an IT enclosure to cool computer equipment exhaust air before it re-enters the data center operating environment. The IBM Rear Door Heat Exchanger patent includes a low impedance fin and tube heat exchanger that does not utilize fans, moving parts or electrical connections of any kind. It is designed to cool a variety of computer, storage and communications equipment loads. IBM's Rear Door Heat Exchanger is also designed to provide 100 percent sensible, noncondensing cooling by using supply water that is maintained above the data center's dew point.
Vette has worked with IBM to develop a full suite of water-cooled Rear Door Heat Exchanger solutions that address a wide variety of common data center cooling problems. Vette Rear Door Heat Exchangers are a well suited solution for existing data centers that are power and cooling capacity constrained, have space limitations or are experiencing hot spots. Vette liquid cooling solutions are non-invasive and can be deployed easily in new data center builds and within data center retrofit projects, especially where redeployment of racks and movement or shutdown of IT gear is undesirable or impossible. Vette's Rear Door Heat Exchangers are designed to integrate seamlessly with third party cooling solutions, such as perimeter computer room air-conditioning (CRAC) and in-row cooling products - delivering up to a 25 percent reduction in comparative Total Cost of Ownership (TCO). For customers with green data center initiatives, Vette Rear Door Heat Exchangers may be able to reduce cooling energy consumption by at least 50 percent compared to next-in-class products and can even be deployed using computer room air conditioning return water or cooling tower return water.
