46 New Data Logger Series Simplifies Access to Data
With the latest models in its TR-7wb series, T&D Corporation, the Japanese market leader for data loggers, has extended the original TR-7wf series with a Bluetooth feature to enhance connectivity between data loggers and mobile devices such as smartphones and tablets. The ThermoApp has also been redesigned with a new look and easier to use interface. T&D Thermo enables the use of mobile devices for viewing recorded data, as well as direct communication between the connected devices TR-71wb, TR-72wb and TR-75wb.
The new TR-7wb model is ideal for temperature and humidity monitoring, and is designed for people who require a broad range of measurement tasks. Recorded data can automatically be uploaded to T&D’s free of charge WebStorage Service, accessible anywhere and any time by computer, smartphone or tablet via mobile Thermo app connection. The new design and easier to use interface plus the option to view data from all networked TR-7wb/nw loggers makes handling with mobile devices easy and effective. The simplicity of these applications allows uncomplicated and cost-effective protection of various goods and processes. They are ideally suited to the supervision of climatic conditions in public buildings and warehousing, as well as storage of sensitive products and the safeguarding of laboratories, server rooms or refrigerators.
A wide selection of optional sensors are available, enabling the two-channel TR-71wb/nw for a wide range of temperature measurements from -60 to 115°C. What’s more, the two-channel TR-72wb/nw measures temperatures and humidity from 0 to 55°C and 10 to 95% RH. The TR72wb-S/nw-S provides higher accuracy to ±2.5% RH and ±0.3°C thanks to the model sensors covering a sector from -25 to 70°C/0 to 99% RH. In contrast, the TR-75wb/nw as a two-channel thermocouple sensor type (K, J, T, E, S, R) provides measurements ranging from -199 to 1760°C.
Their high precision and wide scope of measurement capabilities combined with their flexibility make the TR-7wb data loggers perfect for industrial as well as public use. They can be utilised, for example, in hospitals, museums or subway trains, as well as for facility management to control cooling, heating and humidity.

Process-safe Temperature Control with Natural Refrigerants
Lauda Heating and Cooling Systems, has recently manufactured a process cooling system with a two-stage cooling cascade and natural refrigerants for temperatures down to -60°C for a biopharmaceutical company in Germany.
The system is used for so-called Freeze & Thaw processes, in which active ingredients are deep-frozen in large tanks of up to 200 l volume and shipped for further processing. The process cooling system must therefore be able to cool down to -60°C with high precision.
In close consultation with the customer all specifications of the process cooling system were defined and the individual components were designed during the pre-engineering process. The customer’s factory specifications also had to be taken into account, such as the use of instrumentation from certain manufacturers. The process cooling system is designed for two tanks, each with a cooling capacity of 2.2 kW. The system is also equipped with a volume flow control system to make the entire process reproducible for the customer and to safeguard it at all sites. In order to achieve the required working temperature of -60°C, the Lauda engineers rely on a two-stage cascade system. Two interconnected and coordinated compressor systems provide the required temperature by the evaporator of the first circuit cooling the condenser of the second circuit. This intelligent combination of several cooling circuits allows low temperatures down to -90°C to be reached.
In order to guarantee future-proof operation, the plant for the pharmaceutical company is operated with natural refrigerants. Lauda uses flammable refrigerants such as ethane and prophene for this purpose. The use of these gases in turn places special demands on the system.
From a filling quantity of 150 g combustible gas, the use of a special gas sensor is mandatory, which monitors the tightness of the refrigeration circuits and switches off the process cooling system in case of danger. In addition, the entire refrigeration system is equipped with a ventilated housing to keep air exchange as low as possible. In the event of a leak, a fan ensures sufficient negative pressure and reliable ventilation to the outside. Lauda heating and cooling systems only use components and safety technology approved for the refrigerant in question, strictly in accordance with DIN EN 378.

ilmt.co/PL/qQyj 48307pr@reply-direct.com Highly Reproducible and Sustainable Low Temperature Reactions and Studies
The DrySyn SnowStorm range from Asynt offers an attractive solution for scientists looking to undertake low temperature chemical reactions and studies. Unlike traditional reaction cooling methods, including ice, dry-ice and liquid nitrogen; accurate and prolonged temperature control on a DrySyn SnowStorm is regulated by an external thermostatic circulator. The use of such a temperature control system not only eliminates the risk of temperature fluctuations due to perishable coolants, but can also improve your labs sustainable use of resources.
In addition to allowing unattended operation (even overnight), active temperature control on the DrySyn Snowstorm range also enables responsive control of exothermic reactions, constant rate cooling to enhance polymorph studies and significant improvement in reaction reproducibility. Beneficially the ability to agitate and cool in parallel using a DrySyn Snowstorm can also lead to improved productivity.
The DrySyn Snowstorm systems deliver precise temperature control of reactions from -60 to +150°C and have been designed to be user friendly and practical, with a small bench top footprint. The DrySyn SnowStorm ONE enables controlled chemistry to be conducted on single flasks up to 1 litre in size, whilst the SnowStorm MULTI allows for up to three 100 ml parallel reactions to be undertaken. The use of a weighted silicone seal prevents the formation of ice around the glassware on these systems. For smaller scale experiments, the DrySyn Snowstorm Reactor allows increased throughput and screening of up to 27 vial-based reactions. Purging the dome with nitrogen / argon prevents the formation of ice around the vials at sub-ambient temperatures.
