VARIO® chemistry pumping unit in action

The PC 3012 NT VARIO select pumping unit precisely controls the vacuum level in order to achieve unparalleled process control. With its combination of high pumping speed and deep ultimate vacuum, this pump is suitable for demanding applications with even high boiling point solvents. This pump is regularly used to support floor-standing rotary evaporators, vacuum drying ovens, distillation columns, and other similar work in miniplants, kilo labs, and scale-up facilities.

The integrated VACUU·SELECT controller provides an easy-to-use, application-based interface that covers all common lab applications. The VACUU·SELECT controller has you covered. Use manual set-point-control for simple processes, run fully automated distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, the VACUU·SELECT controller continuously detects the boiling point and automatically adjusts the vacuum process as necessary.

In addition, the VARIO control maintains the desired vacuum level by running the motor only as fast as necessary. This prevents bumping and foaming, makes the pump whisper quiet, and extends maintenance intervals. The inlet separator, made of glass with a robust protective coating, prevents particles and liquid droplets from entering the pump, preventing damage and extending pump life. And the exhaust vapor condenser allows for nearly complete recovery of solvents when used with a chilled water line or recirculating chiller for economical recycling and environmental protection.

With their robust design and precise temperature control, Peltier chillers are ideal for simple temperature control tasks in laboratories and research facilities. They operate without refrigerants and are therefore very environmentally friendly. At the same time, the reliable chillers contribute to lowering operating costs and reducing the ecological footprint thanks to their energy-efficient operation.

The TE400 uses fewer movable components such as compressors for cooling. This makes it comparatively low-maintenance and less susceptible to wear. The Peltier chiller offers a cooling capacity of up to 400 watts and a pump capacity of up to 7 l/min and impresses with its high temperature stability for a wide range of different applications.

Silent Mode

The TE400 Peltier chiller is equipped with an additional operating mode for use with lower cooling power requirements. The noise level is significantly reduced in Silent Mode, contributing to a more pleasant working atmosphere.

Product features

• Touch display for easy operation

The VARIO® select DUO pumping units are consisting of a combination of two individual VARIO® pumping units, connected in parallel on the suction side and driven synchronously by one vacuum controller VACUU•SELECT.

The vacuum is controlled accurately. The speed of the two individual pumps is exactly adjusted to the vacuum needs. The controller allows both fully automatic distillations without any user pre-settings as well as specific and reproducible program sequences. The integration into existing control systems via digital and analog interfaces is also possible. The consequent design to highest chemical resistance provides the ideal prerequisite for universal use in chemistry and pharmacy - without any operating fluid such as water or oil.

Performance features

• automatic adaptation of the vacuum level throughout the process for high process reliability and unattended operation
• short process times due to powerful vacuum pump and accurate (hysteresis-free) vacuum control, even for large amounts of steam

The most powerful, single-stage, highly dynamic temperature control systems

The water-cooled PRESTO W58x is able to quickly and efficiently control the temperature in applications requiring a great deal of power. This model features has an impressive cooling capacity of 33 kW at 20°C, thus ensuring that it maintains large power reserves over its entire working temperature range, especially at temperatures around -30°C to -40°C, which are often necessary for automotive testing.

The PRESTO W58x process system is equipped with a gear pump. As a result, bath fluids with a high viscosity, such as water-glycol mixtures at low temperatures of up to -45 °C, can also be used.

The magnetically coupled pump allows the user to optimally adjust pump capacity to suit the application, even over large distances and height differences, as well as for pressure-sensitive applications. Use of the latest thermodynamic technologies means that the cooling capacity is automatically adjusted to the current power requirements. Combined with further optimizations, the PRESTO W58x is both incredibly economical and energy-efficient.
