The PolyScience Model 3370 (P9A11B) is a reliable, non-refrigerated liquid-to-air cooler engineered for systems requiring fluid cooling above ambient temperatures. With a robust 1/3 HP positive displacement pump capable of 2.4 GPM (9.1 L/min) at 100 psi, it provides steady, contamination-free coolant circulation via an internal radiator and fan.
Featuring a 4.2 L stainless-steel reservoir, convenient low-liquid indicator, and screw-on cap, the 3370 ensures easy maintenance. Operating within an ambient-range temperature of +5 °C to 70 °C, it’s TÜV-certified and includes cleanable air and fluid filters. The compact footprint—20.5″ × 15″ × 22.3″—makes this cooler a flexible choice for a wide variety of lab and light-industrial fluid cooling tasks.
