The COMPREX\u00ae pulse rinsing method developed by Hammann GmbH offers an environmentally-friendly option for cleaning and maintaining cooling systems.<\/p>\n<p>The mechanical COMPREX\u00ae process removes biofilms and deposits from pipes, heat exchangers and other apparatuses by means of specifically controlled compressed air pulses.<\/p>\n<p>Basic cleaning \u2013 usually on an ad hoc basis \u2013 upgrades existing facilities to return them to the condition they were in at the start of operation.<\/p>\n<p>Regular or preventive use of COMPREX\u00ae cleaning helps to maintain the functionality of the systems and extend their useful life.<\/p>\n<p>With the advantages mentioned, the process offers an excellent cost-benefit ratio.<\/p>\n<p>Basic cleaning ensures that the initial condition is restored. Preventively applied COMPREX\u00ae cleaning for maintaining plants and piping systems requires little downtime. Cleaning with COMPREX\u00ae during ongoing plant operation is a particularly economical solution.<\/p>\n<p>The success of COMPREX\u00ae cleaning can essentially be measured on the basis of the heat transfer or the system characteristics. These characteristics can also be used for condition assessment and thus indicate when the next cleaning is required.<\/p>\n<p>In case of very short cleaning intervals, it may make sense for the user to purchase a COMPREX\u00ae unit adapted to the local conditions.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=&#8221;4.19.2&#8243;

Preventively applied COMPREX\u00ae cleaning for maintaining plants and piping systems requires little downtime. Cleaning with COMPREX\u00ae during ongoing plant operation is a particularly economical solution. The success of COMPREX\u00ae cleaning can essentially be measured on the basis of the heat transfer or the system characteristics. These characteristics can also be used for condition assessment and thus indicate when the next cleaning is required. In case of very short cleaning intervals, it may make sense for the user to purchase a COMPREX\u00ae unit adapted to the local conditions.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=&#8221;1&#8243; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_row custom_padding_last_edited=&#8221;on|tablet&#8221; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; custom_padding=&#8221;||0px||false|false&#8221; custom_padding_tablet=&#8221;||0px||false|false&#8221; custom_padding_phone=&#8221;||0px||false|false&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; header_2_font=&#8221;|300|||||||&#8221; header_2_text_align=&#8221;center&#8221; header_2_font_size=&#8221;2.3rem&#8221; header_2_line_height=&#8221;2.9rem&#8221; custom_margin=&#8221;0px|0px|0px|0px|false|false&#8221; custom_padding=&#8221;0px|0px|0px|0px|false|false&#8221; header_2_font_size_tablet=&#8221;1.8rem&#8221; header_2_font_size_phone=&#8221;1.4rem&#8221; header_2_font_size_last_edited=&#8221;on|phone&#8221; header_2_line_height_tablet=&#8221;2.6rem&#8221; header_2_line_height_phone=&#8221;1.9rem&#8221; header_2_line_height_last_edited=&#8221;on|tablet&#8221; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<h2>Your contact partner for H\u2082O technology \u2013 <br \/>natural water treatment<\/h2>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; module_class=&#8221;dfc-vertriebwasser&#8221; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_blurb title=&#8221;GREGOR HEIERMANN&#8221; image=&#8221;https:\/\/www.lr-kaelte.de\/wp-content\/uploads\/2021\/08\/Heiermann_2.jpg&#8221; alt=&#8221;L+R-Industriekaelte-Rubrik&#8221; module_class=&#8221;dfc-vertrieb&#8221; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; header_level=&#8221;h3&#8243; header_font_size=&#8221;1.2rem&#8221; header_line_height=&#8221;1.3em&#8221; body_font=&#8221;Open Sans||||||||&#8221; body_font_size=&#8221;0.9rem&#8221; body_link_text_color=&#8221;#395B73&#8243; background_color=&#8221;RGBA(57,91,115,0.1)&#8221; width=&#8221;33%&#8221; module_alignment=&#8221;center&#8221; header_font_size_tablet=&#8221;1.1rem&#8221; header_font_size_phone=&#8221;1.1rem&#8221; header_font_size_last_edited=&#8221;on|desktop&#8221; header_line_height_tablet=&#8221;1.3em&#8221; header_line_height_phone=&#8221;1.3em&#8221; header_line_height_last_edited=&#8221;on|desktop&#8221; body_font_size_tablet=&#8221;0.9rem&#8221; body_font_size_phone=&#8221;0.9rem&#8221; body_font_size_last_edited=&#8221;on|desktop&#8221; body_line_height_tablet=&#8221;&#8221; body_line_height_phone=&#8221;&#8221; body_line_height_last_edited=&#8221;on|desktop&#8221; custom_css_main_element=&#8221;flex: 0 1 24%;||margin-bottom: 0!important&#8221; custom_css_blurb_title=&#8221;margin-top:-20px&#8221; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221; custom_css_main_element_last_edited=&#8221;on|tablet&#8221; custom_css_main_element_tablet=&#8221;flex: 0 1 49%;||margin-bottom: 20px!important&#8221; custom_css_main_element_phone=&#8221;flex: 0 0 100%;||margin-bottom: 20px!important&#8221;]<\/p>\n<p>WATER TREATMENT SYSTEMS SALES <br \/> Phone +49 2935 9652-210 <br \/> <a href=\"mailto:\">g.heiermann@lr-kaelte.de<\/a> <\/p>\n<p>[\/et_pb_blurb][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CHEMICAL-FREE COOLING SYSTEM CLEANINGCHEMICAL-FREE COOLING SYSTEM CLEANINGWater treatment only makes sense if the cooling circuits are clean.
