The large scrolling marquee and optional navigator display provide our technicians with all the operational and performance data we need for servicing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">EcoBlue Technology reinvents the wheel<\/h3>\n\n\n\n<p>Carrier\u2019s latest innovation is EcoBlue Technology found on select WeatherMaster and WeatherMaker models.&nbsp; The goal was to improve performance and efficiency while decreasing maintenance and installation costs.<\/p>\n\n\n\n<p>The belt drive was replaced with an all new vane axial indoor fan.&nbsp; The direct-drive ECM motor and dynamically balanced blade fan delivers quieter operation and reduces operating costs. The outdoor fan system has a durable high-density composite fan blade and permanently lubricated motor bearings for high efficiency and reliability.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>No belts or pulleys<\/li><li>No shaft or shaft bearings<\/li><li>Intuitive fan speed adjustment controls<\/li><li>Same footprint = lower install costs &amp; easy replacement<\/li><\/ul>\n\n\n\n<p>This simpler (and more compact) design has 75% fewer moving parts and can be up to 40% more energy efficient for lowered operating costs. &nbsp;For added convenience, it has a tool-less filter access door for quicker servicing and changing of filters.<\/p>\n\n\n\n<p>In future posts, we\u2019ll showcase other Carrier commercial equipment installed by K &amp; D Mechanical, Inc throughout the Seattle-Tacoma metro area.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Carrier&#8217;s line of commercial equipment includes the Weather Series of packaged rooftop units.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[2],"tags":[],"class_list":["post-11","post","type-post","status-publish","format-standard","hentry","category-equipment"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
