Description
The FLW2503 recirculating cooler in tall design is a water-cooled mid-range laboratory chiller built for applications that need higher cooling capacity and stable circulation. It combines a powerful immersion pump with an integrated stainless steel bath vessel offering fill volumes up to 30 litres, supporting continuous-duty temperature control. Microprocessor PID regulation, a large bright LED temperature display and splash-proof membrane keypads enable precise, ergonomic operation. A permissible return temperature of +80 °C, easy top filling through a hinged opening, and low-level protection with optical and acoustic signals increase process safety. The front-mounted drain tap is readily accessible, and the absence of side ventilation slots allows units to stand side by side. Further interfaces include RS232 for PC connection, a pump pressure display and a potential-free alarm output (max. 30 VA); IP class is 21 according to IEC 60529. Cooling capacity is stated per DIN 12876 (values at 20 °C ambient). Scope of delivery covers hose olives for the G3/4 pump connections and the G3/4 cooling-water inlet. This upright FLW model from manufacturer Julabo suits demanding laboratory and technical cooling loops.

Questions about FLW2503 Recirculating cooler
What is this article?
FLW2503 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.
