However, it is possible to delay deterioration and extend its useful life through proper management. This article will provide some practical advice on how to keep the heat transfer fluid in good condition and maximize system efficiency.<\/p>\n

The heat transfer<\/strong> system is designed to remove thermal energy from a heat source using a heat transfer fluid<\/strong>. The system and its components are sized according to the physical properties of a new, uncontaminated fluid. Therefore, the ability of the system to maintain high performance<\/strong> depends on keeping the fluid in good condition.<\/p>\n

The challenge for system operators<\/strong> is to keep the heat transfer fluid, which is the beating heart of the system, as close to its initial condition<\/strong> as possible. Without proper care,<\/strong> heat exchange surfaces can become dirty, increasing the amount of energy required to maintain the desired temperature and thus reducing system efficiency<\/strong>.<\/p>\n

As the heat transfer fluid degrades<\/strong>, its initial properties change and continue to change as the severity of degradation increases<\/strong>. So, the question becomes: how to keep the system as efficient and productive as when first filled, despite the gradual deterioration of the fluid over time?<\/strong><\/p>\n

In this article, we will try to answer this question<\/strong>. Although no expert can keep diathermic fluid in perfect condition forever, system operators can certainly extend its useful life by avoiding common threats of degradation and selecting the most suitable<\/strong> fluid for the application<\/strong>.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][divider line_type=”No Line” custom_height=”20″][image_with_animation image_url=”19392″ image_size=”full” animation_type=”entrance” animation=”None” animation_movement_type=”transform_y” hover_animation=”none” alignment=”center” border_radius=”15px” box_shadow=”none” image_loading=”default” max_width=”100%” max_width_mobile=”default”][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][vc_column_text]\n

The most common causes of heat transfer fluid degradation<\/h2>\n[\/vc_column_text][vc_column_text]Before examining strategies to extend the useful life of the fluid, it is important to understand the main causes of its degradation. The three main causes are:<\/span><\/p>\n
    \n
  1. Thermal degradation<\/strong><\/a><\/li>\n
  2. Oxidative degradation<\/strong><\/a><\/li>\n
  3. External contamination<\/strong><\/a><\/li>\n<\/ol>\n[\/vc_column_text][vc_column_text el_id=”degradazione”]\n

    Thermal degradation or cracking<\/h3>\n[\/vc_column_text][vc_column_text]This phenomenon occurs when fluid molecules receive more<\/strong> heat<\/strong> energy<\/strong> than they can absorb. In organic-based fluids, such as mineral oils or chemical aromatic compounds, thermal cracking<\/strong> causes the breaking of chemical bonds within fluid molecules. This leads to the formation of carbon-like residue<\/strong> that can clog the system and cause damage to seals and electrical elements<\/strong>.
