Strong Recirculating Coolers FL Series

Category Chillers
Manufacturer Julabo
Country of manufacture Germany
Overview

The FL series offers a new generation of chillers for routine cooling applications within the laboratory and industry. The temperature stability of the PID control is ±0.5°C. All units can easily be cleaned and are provided with a splash water proof keypad with LED temperature indication. On the front of the units there is an RS232 interface as well as an alarm shutdown. The filling port is easily accessible placed on the top under a lift-up cover. Another hinged tray serves as a file for the operating manual or other documents concerning the installation. The removable venting grid allows an easy cleaning of the condenser, the drain tap is easily accessible behind the grid. All models include an easily visible level indication. Another advantage is the venting slots are on the front and rear and therefore the units can be placed directly one beside the other (space saving).

Features:

• Ergonomic design and easy operation
• Splash-proof keypad with integrated mains switch
• Large, bright LED display
• Reliable Microprocessor PID temperature control
• Filling level indicator
• Powerful immersion pumps, suitable for continuous operation
• Permissible temperature in return line +80°C
• Easy filling from the top with hinged protective lid
• Low liquid level protection with optical and audible alarm signal
• Integrated stainless steel bath tanks
• Removable venting grid for cleaning of the condenser
• Front drain
• No side vents
• RS232 interface for PC-connection
• IP class according to IEC 60529: 21

FAQ

Do the FL Series chillers have any means for temperature feedback and control of cooling?

There is no such functionality built in, but the FL Series chillers do have an RS232 connection, so you can control operation with a PC. If you also had a temperature sensor connected to the PC, you could program a sort of feedback mechanism that would control the cooling.

Unless you have a program allowing you to easily manage equipment via RS232, it's not a particularly simple task and would require the appropriate coding capabilities.

 

Can I run a Strong FL Series Recirculating Cooler continuously under maximum load?

Yes. Julabo chillers are designed for maximum operation at maximum load specifications. However, be very certain of the cooling power requirements such that you are not overloading the chiller. In a stressful situation such as continuous operation, overloading the chiller could damage the condenser and render the chiller useless. Also, for air-cooled models, operating the chiller in a hot environment or a dirty / dusty environment could decrease the efficiency of the chiller, so if operating at or near maximum load be sure that the chiller is in a cool, clean environment.
