maximum temperature of 55°C. Hot water heating prov ided through 316L stainless steel heating coils
is recommended. Low pressure steam heating through coils can be used, but for short period (< 1
hour) and only with adequate agitation to avoid local overheating. 316L stainless steel positive
displacement pumps should be used. Piping should be of 316L stainless steel. Rubber hoses lined
