Description
The FLW4003 recirculating cooler in tall design is a water-cooled mid-range chiller intended for laboratory and process cooling tasks that require elevated refrigeration capacity and strong circulation. An immersion pump and integrated stainless steel bath vessel with fill volumes up to 30 litres provide dependable heat transfer under continuous operation. Reliable microprocessor PID temperature control is paired with a large, bright LED display and splash-proof foil keypads for clear, ergonomic handling. The unit accepts return temperatures up to +80 °C, offers simple filling from above via a hinged opening, and includes low-level protection with optical and acoustic alarms. A front drain cock, side-by-side installation without lateral air slots, RS232 PC interface, pump pressure indication and a potential-free alarm contact (max. 30 VA) support flexible integration; IP rating is 21 per IEC 60529. Cooling performance data follow DIN 12876 and refer to 20 °C ambient conditions. Delivery includes hose olives for the G3/4 external pump threads and the G3/4 cooling-water connection with 1/2 in. hose barb. This tall FLW series cooler from manufacturer Julabo is suited to robust, space-efficient laboratory cooling setups.

Questions about FLW4003 Recirculating cooler
What is this article?
FLW4003 Recirculating cooler is the article on this page. Luminix Health distributes Julabo for laboratory use. It sits in Circulators, chillers & thermostats, inside Heating, drying & cooling, in Lab instruments.
A circulator or thermostat holds a bath liquid at a set temperature and pumps it through a jacket. A chiller is the same idea aimed below ambient. The temperature range, the cooling power and the pump flow are the three numbers. The fluid has to match the range.
Temperature equipment either holds a set point or drives a sample toward one. An oven dries. A furnace reaches the temperatures of ashing and melting. A bath surrounds a vessel with water or oil. A circulator moves that fluid. An incubator holds the mild warmth of a culture. An autoclave uses steam under pressure to sterilise. The number that matters is the temperature the article actually reaches, not the number painted on the dial. Temperature is part of the international system kept by the BIPM and compared by EURAMET.
