This insulation optimizes the efficiency of the equipment and minimizes operating costs. Forced air circulation systems are standard in these chambers to maintain precise temperatures. The fan is powered by a direct drive, heavy-duty electric motor, externally mounted with an integral stainless steel shaft. The heating systems in our chambers are open wire nichrome resistance elements which combine maximum heat transfer with rapid response time and long operating life. The heaters are located in a plenum, such that, test specimens are not subject to direct radiation.
All Associated chambers feature, as a standard, a high temperature fail-safe control.
This fail-safe provides added insurance against damage due to abnormal high temperature extremes. In addition, chambers are fitted with fusible thermal links to guard against temperatures exceeding the upper design limits of the equipment.
