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
• Alarm output, potential-free change-over contact (max. 30 VA)
• Pressure Indicator
• By-pass valve to adjust pump pressure

FLW2503, FLW2506, FLW4003, and FLW4006 models are Water Cooled compressor models.

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.

Great chair!
Color: Black
Had some issues with Delivery! But got the chair. Beautiful and comfortable. Had one once before as a gaming chair, same kind but bought it from walmart. I used to fall asleep in it all the time. Now i have it for work! One of the best chairs for the cheapest price you can get! If you want a more comfortable chair then this..... your looking at about 300 bucks. Which is next on my list! It comes with its own screws and washers. The manual is self explanatory however you do kinda gotta play the guessing game. It's pretty simple! match the screws up with the ones in diagram. It comes with an Alan wrench. Your hand might be a bit tired tho. I advise to tighten them with super lock tight or gorilla glue so they never come unloose. And gorilla glue the bolt covers on. Keep in mind if you use gorilla glue..... they will never come off. Lol. But as far as tighting it.... do not over tighten it. Tighten enough to where you have to put some pressure on it to turn it half way and stop. Another tip, it's a bit of a pain to set it up with one person. If you got an extra set of hands... use em. If not.... you might be their for a bit. Start with setting up base. Then put arms on seat. (Keep bolts loose but screwed in. You'll see why later when you tighten them down) Then attach back to arms and seat. (Now make sure bolts are in holes and tighten them down. But not at once! Do about 4 turns, move to another one. Then the other side. It's like tightening lug nuts on the wheel of a car. If you tighten one all the way down it will throw all the other bolts off and make it much more difficult to ease the bolts into the holes they go in) Then attach seat to base. Believe me. It's way easier if you do it like that instead of how the installation instructions say. After that, put the caps on the holes to cover the bolts. If you don't glue them, they will pop off ..... their not..... super good. But!!!! 1 or 2 drops of gorilla glue and you never have to worry about them popping off. (They seem like they go on their tight, but they don't stay on!)

Nice chair but definitely not breathable.
Color: Black
Once I figured out the arms had a left and right...the chair was easy to put together. The faux leather is nice. The seat is (or will be once I break it in) very comfortable. I have 2 minor complaints. It is extremely straight up and down. I haven't had much chance to play with it to see if I can get it to recline even an inch. That would help. And number two, it's HOT. I'm going to have to get some sort of seat pad because the pleather is not breathable and every time I get up my bum is sweaty. I know, TMI. But all in all I think it will serve my purposes.

Beautiful chair, comfortable and rolls well, the directions were not very clear, we had the seat on backward at first, but finally figured it out and the chair is perfect, I've had it over a year and it works perfectly

Good quality, fairly easy assembly
Color: White
Comfortable chair as advertised. Assembly time about 20 minutes with one screwdriver needed. (Note: don't follow the instructions included. Lay the left arm assembly down on the floor and THEN affix the seat, followed by turning that over on its side and adding the right arm assembly. Trying to affix the two arms in an upright position is too difficult as directed.) The only thing I don't like about it is the fluted upholstery on the seat and back, where a bit more padding would have helped greatly. Otherwise, it's comfortable and functional and reasonably priced. Delivery was on time. ADDITIONAL COMMENTS AFTER 18 MONTHS OF USE: I've used the chair for 6-8 hours a day. The leather on the arms is cracking in multiple places. This is a big disappointment. And speaking of the arms, there's a major problem with the sewing of the leather on the outside edge of both left and right arms: the stitching is on the top at the outer edge, which means that it forms a jagged edge that your arms scrape on when resting on the leather. That jagged edge scraping my skin has caused a great deal of chafing, is most irritating, and could have been avoided entirely if they had just applied the stitching one inch further down on the side rather than along the top flat edge. This is a major design flaw. I will not buy this chair again because of the one flaw and the too-thin, cracking leather on the flat top of the arms, which is too bad, because it's fine in all other ways.
