Mainly standard aluminum <\/span><span lang=\"en-US\">diving cylinders <\/span><span lang=\"en-US\">of the sizes 40 cuft, 80 cuft, 7 ltr and 12 ltr are used as storage tanks. The advantages of this storage configuration are high variability, free positioning on the ship (trimming) and the reduction of refilling processes due to the direct usage of the storage tanks as back \u2013 or decompression tanks.<\/span><\/p>\n<h6 align=\"justify\"><span lang=\"en-US\">Compressors<\/span><\/h6>\n<p align=\"justify\"><span lang=\"en-US\">Two, individually operated, water cooled high-pressure breathing gas compressors are used. They feature a saturation-controlled scrubber and molecular sieve-filtering system, a performance of 520 liters per minute and a maximum pressure of 350 bars. The quality of the CO-, and CO<\/span><sub><span lang=\"en-US\">2<\/span><\/sub><span lang=\"en-US\">&#8211; levels, vapor and oil aerosols is <\/span><span lang=\"en-US\"><u>constantly<\/u><\/span><span lang=\"en-US\"> monitored and ensures Tec-Air-Standards* to 100%.

This guarantees that only the purest, completely dry sea air enters the compressors and further the scuba tanks. The sea water cooling enables a smooth operation, even at high outdoor temperature levels and ensures a low warming and therefore a high degree of filling of the storage tanks.<a href=\"https:\/\/oceanrabble.org\/wp-content\/uploads\/diagram-test.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-2054 size-medium alignright\" src=\"https:\/\/oceanrabble.org\/wp-content\/uploads\/diagram-test-300x175.jpg\" alt=\"\" width=\"300\" height=\"175\" srcset=\"https:\/\/oceanrabble.org\/wp-content\/uploads\/diagram-test-300x175.jpg 300w, https:\/\/oceanrabble.org\/wp-content\/uploads\/diagram-test-1024x597.jpg 1024w, https:\/\/oceanrabble.org\/wp-content\/uploads\/diagram-test-768x448.jpg 768w, https:\/\/oceanrabble.org\/wp-content\/uploads\/diagram-test.jpg 1234w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/span><\/p>\n<h3 align=\"justify\"><span lang=\"en-US\">Service<\/span><\/h3>\n<h6 align=\"justify\"><span lang=\"en-US\">Workshop with service station<\/span><\/h6>\n<p align=\"justify\"><span lang=\"en-US\">Service \u2013 and repair work on breathing regulator and other PSA are a matter of trust. Most service-providers still lack an \u201coxygen-clean\u201d work station, where regulators, tanks and other equipment, which is exposed to a higher partial oxygen pressure level, can be maintained or repaired. Our on-board safety-workplace is equipped with all necessary service- and special tools to guarantee a professional breathing regulator revision. It furthermore includes an autoclave for disinfection and an ultrasound cleanser for physically removing deposits through a combination of a washing and drying process with multi-step circulated rinsing and a steam blaster for complete, residue-free removal of lubricants and depositions. The way in which all parts are assembles (glove box), ensures that the newly cleaned parts are not contaminated with (non-oxygen compatible) lubricants anew. The reviewing and setting of the breathing regulators is performed at an electronically documented. During the process, high- and medium pressure, the response characteristic and breathing work are checked and documented.<\/span><\/p>\n<p>Glove box for breathing regulator service<\/p>\n<h3>Mobile diving equipment<\/h3>\n<p align=\"justify\">On board the <strong>2HE-2<\/strong> you have extensive Tec diving equipment &#8211; OC and CC &#8211; from the leading manufacturers at your disposal:<\/p>\n<h4 class=\"western\" align=\"justify\">Equipment for rental<\/h4>\n<ul>\n<li><span lang=\"en-US\">Diving regulator<\/span><span lang=\"en-US\"> (Xstream, Tek3, DS4\/XTX oxyclean)<\/span><\/li>\n<li>Wings\/backplates (Halcyon)<\/li>\n<li>Aluminium doubles<\/li>\n<li>Aluminium stages with 7 ltr, 80 or 40 cuft<\/li>\n<li>CCR-Steel-cylinders (200\/300 bar)<\/li>\n<li>Scooter (Suex, Bonex)<\/li>\n<li>Dive lights<\/li>\n<li>computers<\/li>\n<li>Drysuits<\/li>\n<li>Semi-drysuits<\/li>\n<li>CCRs (<a href=\"https:\/\/oceanrabble.org\/?page_id=326\"><strong><em>2HE-<\/em><\/strong><i><b>HPCCR<\/b><\/i><\/a> and other brands)<\/li>\n<\/ul>\n<hr \/>\n<p align=\"justify\"><span lang=\"en-US\">*<\/span><span lang=\"en-US\"><i>The compliance with the limits of the air quality standards DIN EN 12021 concerning the appropriate purity of the breathing gases is not given by far in technical diving. This is due to the increased partial pressure of the gases on question, which increases their physiological effectiveness. For example, the EN 12021 states a limit of 15 ml\/m\u00b3 of CO. This is quite valid for dives up to 50 m, but not for greater depths. We have therefore set a limit of 2 ml\/m\u00b3 for breathing gas blends for up to 200 m.<\/i><\/span><\/p>\n<p><em>\u00a0<\/em>\u00a0<\/p>\n\n\n<!-- Page-list plugin v.6.3 wordpress.org\/plugins\/page-list\/ -->\n<ul class=\"page-list siblings-page-list \">\n<li class=\"page_item page-item-745\"><a href=\"https:\/\/oceanrabble.org\/?page_id=745\">Diving equipment<\/a><\/li>\n<li class=\"page_item page-item-336\"><a href=\"https:\/\/oceanrabble.org\/?page_id=336\">Diving Chamber<\/a><\/li>\n<li class=\"page_item page-item-334\"><a href=\"https:\/\/oceanrabble.org\/?page_id=334\">Exploration equipment<\/a><\/li>\n\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Stationary diving equipment Diving gases Electronically controlled precision gas blending equipment Our electronically controlled gas blending equipment works according to the partial pressure process and renews highly precise gas blends &#8230;<\/p>\n","protected":false},"author":1,"featured_media":2060,"parent":1273,"menu_order":1,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-745","page","type-page","status-publish","has-post-thumbnail","hentry"],"_links":{"self":[{"href":"https:\/\/oceanrabble.org\/index.php?rest_route=\/wp\/v2\/pages\/745","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/oceanrabble.org\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/oceanrabble.org\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/oceanrabble.org\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/oceanrabble.org\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=745"}],"version-history":[{"count":8,"href":"https:\/\/oceanrabble.org\/index.php?rest_route=\/wp\/v2\/pages\/745\/revisions"}],"predecessor-version":[{"id":2057,"href":"https:\/\/oceanrabble.org\/index.php?rest_route=\/wp\/v2\/pages\/745\/revisions\/2057"}],"up":[{"embeddable":true,"href":"https:\/\/oceanrabble.org\/index.php?rest_route=\/wp\/v2\/pages\/1273"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/oceanrabble.org\/index.php?rest_route=\/wp\/v2\/media\/2060"}],"wp:attachment":[{"href":"https:\/\/oceanrabble.org\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=745"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
