JULABO recirculating coolers can handle virtually any cooling requirements in laboratories or industrial environments.

Applications include use with rotary evaporators, autoclaves, reaction vessels and for routine laboratory cooling. All units have an LED temperature display for actual/set point integrated into a splash-proof keypad and recessed grips for easy relocation integrated in the housing. A hinged tray serves as a compartment for the operating manual and other documents. The removable venting grid allows for easy cleaning of the condenser. Venting slots are located on the front and back, allowing units to be placed directly next to each other. Models FL2503 to FLW11006 have an early warning function with sensor monitoring to signal if the condenser is dirty, and online diagnostics with 'BlackBox' function.

JULABO FL models have a temperature range of −25 to 40 °C with PID control for a temperature stability of ±0,5 °C. Units fill from the top with a protective hinged lid and include an easily visible level indicator. Models with >14.5 PSI display pump pressure on a gauge and include a pump pressure by-pass valve to adjust the pump capacity. Visual and audible alarms signal low liquid level. RS232 interface and analog alarm output are located on the front panel for easy access. Units FL4003, FL4006, FLW4006, FLW7006, FL7006, FL20006, FLW7006, FLW11006 and FLW20006 require 230 V, 3-phase power.

Their efficiency makes them an environmentally-friendly and economical alternative to cooling with tap water. Compact models from JULABO are ideal for placement on or underneath a laboratory bench. JULABO offers several powerful models with up to 20 kW of cooling capacity for applications in industrial environments. Models can be either air or water cooled and feature proportional cooling control which adjusts cooling capacity based upon the application, lowers energy consumption and extends component lifetimes.
