Hydra offers a choice of pump and heater combinations matched to specific needs. The high-speed controller and direct heating and cooling ensure fast response and tight control. The pressurized system circulates plain water through the mold for heat transfer. Pressurization of the water allows temperatures up to 250oF (121oC). The microprocessor control provides accuracy to +/-1oF with an adaptive self-tuning PID and two large digital displays for setting and reading system temperatures. By automatically cooling process water to 90oF (32oC), the unit may extend seal life and minimize hose temperatures.
