Q: What refrigerants are available for Kolant heat pumps?<\/p>\n

A: Kolant offers multiple refrigerant options to meet different regional regulations and application requirements:<\/p>\n

    \n
  1. R290 (Propane)<\/strong> \u2013 Natural low-GWP refrigerant, GWP\u22483. Main option for EU market, ideal for residential all-in-one heating & cooling systems and pool heat pumps, compliant with F-Gas regulation and achieving A+++ energy class.<\/li>\n
  2. R32<\/strong> \u2013 Low-GWP refrigerant widely used in EVI ultra-low temperature units, pool heat pumps and ice bath chillers. It delivers excellent performance at low ambient temperatures and is a popular selection for European exports.<\/li>\n
  3. R410A<\/strong> \u2013 Traditional refrigerant adopted on older models and some dual-source heat pumps. It is gradually phased out for new EU projects due to F-Gas restrictions.<\/li>\n
  4. R410A + R134a (Cascade system)<\/strong> \u2013 Special solution for high-temperature industrial heat pumps. This two-stage cascade unit can work at -35\u00b0C ambient temperature with maximum water outlet up to 90\u00b0C. Separate circuits use R410A and R134a respectively.<\/li>\n<\/ol>\n

    Q: How to choose the refrigerant version? A: New projects for Europe normally select R290 or R32<\/strong>.<\/p>\n

    R410A is only available for legacy model replacements. High temperature industrial heating applications adopt the cascade system with R410A + R134a.<\/p>","protected":false},"featured_media":0,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"categories":[],"faqcat":[397],"class_list":["post-8042","heatpump_faqs","type-heatpump_faqs","status-publish","hentry","faqcat-heat-pump-faqs"],"_links":{"self":[{"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/heatpump_faqs\/8042","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/heatpump_faqs"}],"about":[{"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/types\/heatpump_faqs"}],"version-history":[{"count":0,"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/heatpump_faqs\/8042\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/media?parent=8042"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/categories?post=8042"},{"taxonomy":"faqcat","embeddable":true,"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/faqcat?post=8042"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
