Description
FL4003 upright recirculating cooler is a mid-range air-cooled recirculating cooler engineered for higher cooling capacity in laboratory and process environments. It combines a powerful immersion pump with an integrated stainless-steel bath vessel offering a filling volume of up to 30 litres, supporting continuous-duty circulation. Precise microprocessor PID temperature control is complemented by a large, bright LED temperature display and splash-proof membrane keypads for clear, ergonomic operation. Filling is performed from above through a hinged opening, while low-level protection with optical and acoustic signals enhances bath safety. The permissible return temperature is +80 °C. A front-accessible drain cock, delivery-pressure display and RS232 interface for PC connection support practical daily use. With no side ventilation slots, units can stand side by side. IP class according to IEC 60529 is 21, and an alarm output provides a potential-free changeover contact (max. 30 VA). Cooling capacity data are determined in accordance with DIN 12876 at 20 °C ambient temperature. This upright cooler from manufacturer Julabo is supplied as one unit with a net weight of 148 kg for stable recirculating cooling duties.
This article belongs on Circulators, chillers & thermostats, in Heating, drying & cooling.

Questions about FL4003 Recirculating cooler
What is this article?
FL4003 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.
