Extra Silent Recirculating Chiller for Professional Applications

The ULKs are FRYKA-Kältetechnik's new generation of circulating coolers. During their development, special emphasis was placed on energy efficiency and ease-of-use. The specially quiet fan with EC technology adjusts its speed to the required value which means you benefit from reduced energy consumption and quieter operation. The other components, such as the pump, for example, were also chosen with an eye to quiet operation.

The integrated funnel on the upper side of the device, the self-sealing hose connector with quick coupling and the drain cock make the tasks of filling, emptying and hose changeover straightforward, clean and convenient. In terms of user friendliness, the circulating cooler also distinguishes itself by its good accessibility and intuitively operated touchscreen controller. The controller's high-grade glass screen is easy to clean with good readability. The flow and digital fill level indicators are integrated into the controller. Error messages are displayed in plain text.

Thanks to freeze-up and thermal overload protection as well as flow control with dry running protection (disconnection of pump when there's too little water), the device enjoys high operational reliability thereby protecting your applications and circulating cooler. An optical and acoustical alarm warns you if the minimum or maximum permitted temperature is exceeded.

Another highlight of the completely new development is its flexible use in various applications. On the one hand the ten litre coolant tank can provide high temperature stability or operate as a cold reservoir to help cushion cooling demand peaks. On the other hand, by minimally filling the device you have a very dynamic system with short cooling times which can quickly react to your cooling demands. 

The circulating coolers with cooling capacities of 1200 and 2300 Watt and a temperature range of -10°C to +40°C are suitable for the widest range of cooling applications in laboratories, processes and production e.g. for cooling rotary evaporators, fermenters, electron microscopes, lasers or industrial and manufacturing plants. Thanks to the high quality workmanship and designed-in longevity, the ULKs are an interesting and economical alternative to tap water cooling.

The new devices with their attractive design fit into the wide portfolio of professional freezers.
