A device for storing andor treating chemicals is described. The heater includes a direct heating section and a radiant heating section. A ground engaging foot is disposed at a lower end of each of the legs. At least one holding device is provided for holding the swivel elements in the open position against the pretensioning force generated by the tensioning mechanism. The system further invokes the external computer program to generate a value for the custom parameter. An electrically conductive gasket attached to the underside of the elevated section may contact the heat sinks, further minimizing the radiation of EMI emissions.
