Room Temperature / Airflow Countermeasure
Room Temperature Control
In order to realize the full potential of high-performance scientific instruments, such as atomic-resolution electron microscopes, it is necessary to maintain a high level of stability of the operation environment, including room temperature variation, air flow and acoustic noise. JEOL has developed a unique and optimal room temperature control system for atomic-resolution electron microscopes, which has been highly praised by many users.
Principles of Hydro radiant panel temperature control systems
Cooling water from a dedicated, high-precision chiller flows within the several radiant cooling panels that are installed on the walls of the instrument installation room. The natural convection flow and the radiant cooling eliminate the heat generated by the instrument. Compared to an ordinary air conditioning system, the temperature stability is surprisingly better, with almost no air drafts or noise, creating the ideal environment for the operation of an atomic-resolution electron microscope.
