Lauda, a thermostating specialist, presented seven models from the new line of Integral XT process thermostats for the first time at Achema 2006.
These devices have been designed for professional temperature control applications in the fields of testing and mini-plants.
They have clear advantages with regard to heating capacity, cooling capacity, temperature range, speed of the temperature changes and user-friendliness compared to the Integral T range of process thermostats.
Wherever fast temperature changes and quick reaction times are required, the process thermostats show their strengths.
Typical applications are the thermostating of double-walled glass or metal reactors in the chemical and pharmaceutical industries, of reaction blocks in combinational chemistry and stirrer tanks and fermenters in the field of biotechnology.
The Lauda Integral XT process thermostats are characterized by extremely-fast temperature changes which are founded in the low, internally thermostated heat-transfer volumes.
The efficient devices work according to a completely new technical principle, and achieve an extremely wide operating temperature range of between -50 and +300C.
The bath liquid circulates in the entire system, and does not come into direct contact with the ambient air.
An expansion vessel which is not thermostated is used for the volume compensation in case of temperature changes.
This operational principle avoids the condensation of air humidity at ambient temperatures, or prevents odour nuisance at high temperatures.
Furthermore, the service lives of the bath liquid are increased by up to 50% thanks to low evaporation or oxidation.
This reduces operating costs and increases the level of process safety.
A decisive advantage is the operation throughout the entire temperature range of -50 to +200C without the need to change media.
It is possible to work above the burning point of the bath liquid, since the expansion vessel is not flown through.
A further advantage is the powerful, eight-stage Variopump.
Maximum pressure between 2.9 and 5.8bar and 45 to 90l/min flow guarantee optimum heat transfer from and to the consumer, even in the event of considerable distances.
Thanks to the adjustable pressure control, stainless steel reactors can be temperature controlled just as quickly and safely as pressure-sensitive glass apparatus.
Many further important functions of the Integral XT simplify daily working processes.
The command console with graphic display familiar to users of the Lauda Proline range is used for easy operation.
The entire thermostating system is graphically displayed, and all important parameters are visible at a glance.
The Lauda Integral XT range of devices is divided into three sizes.
The two table-top models of the Integral XT 150 and the water-cooled XT 250 W are the most compact members of the family.
