The Thermo Neslab HX-540 is a three-phase recirculating chiller engineered for precise temperature control in laboratory and industrial cooling applications. This water-cooled system delivers stable temperature maintenance across variable heat loads, making it suitable for laser cooling, analytical instrumentation, semiconductor manufacturing, and reaction vessel temperature management. A microprocessor controller maintains operating temperature stability typically within a few tenths of a degree Celsius, while the stainless steel reservoir and continuous-duty design ensure reliable long-term operation in demanding environments.
