Best by design, performance and reliability

Even if water is one of the most precious and scarce resources, it is still largely used as coolant in many laboratories. Most of the water used as coolant unfortunately is not recycled, causing higher and higher laboratory costs and wasting a precious natural resource. LabTech offers a complete line of recirculating water chillers to virtually match all laboratory needs with 10 models featuring temperatures from -20 to 35°C and cooling capacities from 500W to 9000W. LabTech’s state-of-the-art water chillers ensure accurate and constant cooling conditions of instruments even in the harsh laboratory environments while reducing the carbon footprint. When designing the most recent series LabTech’s R&D team, among other crucial parameters, focused its attention on the noise, already low and very much appreciated by countless of users worldwide, and the result is a further reduced level. Thanks to the excellent price/performance ratio, robustness, reliability, quietness and simplicity to use there are more than 35.000 LabTech water chillers installed worldwide positioning our brand among the most important players of the industry. In addition to standard models numerous customized versions are available.

High energy efficiency

The “hot gas bypass” technology carries back the hot. uncondensed refrigerant through a reservoir coil eliminating both the ON/OFF compressor cycle and energy-waste.

Accurate temperature

P.I.D. is a dynamic temperature control technique through proportional. integral derivative algorithms controls that guarantees precise and stable temperature setpoint.

High quality components

All parts used in LabTech’s chillers have to pass strict quality control tests: the quality control ensures a long lifespan even with 24/7 use.

New lightweight chiller

One of the most successful LabTech lines is now enhanced with a new lightweight portable chiller. The instrument conjugates excellent cooling capabilities with portability and compactness. Thanks to the lack of the compressor and the semiconductor refrigeration technology (Peltier cell) it is extremely light while delivering a cooling power of 240W at 25°C. The compact footprint allows to position it almost everywhere. The temperature ranges from 5°C to 35°C with an accuracy of ±0.05°C. The bright LCD display can be seen from across the laboratory. High & low temperature and low liquid level alarms provide full safety. All this, along with a flow rate of 5L/min, a pressure of 0.4 bar and a tank volume of 0.6 L, makes the H50-240 the ideal solution for UV-VIS applications and all in need of a portable, efficient and flexible instrument.

Genetec is a member of the same family of companies as Kovalent. Both companies share the same set of values and are in many ways integrated with each other. The main difference between the two companies are their products. Kovalent is involved in system solutions including instrumentation and Genetec is mainly working with consumables. The focus of Genetec is chromatography accessories. You are welcome to visit their state of the art web shop:
