More About this Item

These chillers can cool at ambient temperatures as high as 35°C. They are a good standard option that provides optimal reliability. Heater option provides the ability to go up to 70°C for applications that require increasing temperature above ambient before chilling can begin. These also have excellent additional features such as user-adjustable temperature, pressure, and flow rate alarms. The units run quiet, minimizing noise pollution for the user.
Different pump types are available for a varierty of applications. The turbine pump models are hardy and can last as long as 55,000 hours because the turbine style allows particles to pass through it without binding. The magnetic pump models always provide a fixed pressure at 10 psi. The positive displacement pump models offer the opposite, and users can adjust their pressure while flow rate remains fixed.


Turbine pump models have an internal pressure relief valve that provides adjustable pumping pressure from 20 to 100 psi and a front-panel gauge let you monitor pressure.
