More than 20 models for laboratory and industrial applications Recirculating coolers for economical and environmentally friendly cooling. The FL Series offers a new generation of recirculating chillers for a wide variety of laboratory and industrial cooling applications. The temperature constancy of the PID control is ± 0.5 ° C. The devices are equipped with an easy-to-clean and splash-proof membrane keypad with LED temperature display, in addition, there is an RS232 interface and an alarm output on the front of the device. The filling opening is easily accessible at the top, protected by a hinged cover. Another hinged compartment is used to store the operating instructions or other device documents. The removable ventilation grille allows easy cleaning of the condenser, behind the grid is the drain tap. Further features of all models include a well-visible level indicator. Another advantage is the absence of side vents, the devices can be placed directly next to other devices (space gain). Ergonomic design and ease-of-use Spill-resistant membrane keypad with integrated power switch Large, bright LED temperature display Reliable microprocessor PID temperature control Level indicator Durable, high-performance submersible pumps Allowable return temperature + 80 ° C Easy top filling with hinged filler neck Lower level guard with optical and acoustic signal Integrated stainless steel bath tanks Removable ventilation grille for easy cleaning of the condenser Easily accessible drain tap on the front side No side ventilation slots RS232 interface for direct PC connection IP class according to IEC 60529: 21 Alarm output, potential-free changeover contact (max 30 VA) Pump pressure indicator Pump pressure bypass for power setting
