Its main purpose is to protect the monobloc heat pump from freezing in the event of an electrical power failure.<\/p>\n<h4>How does the anti-freeze valve work?<\/h4>\n<p style=\"text-align: left;\">The anti-freeze valve, installed in a heat pump system, allows a slow bleed when the medium temperature drops below 3\u00b0C. The valve is fitted with a specially calibrated thermostatic insert which opens the water bleed when the medium temperature in the valve drops below 3\u00b0C. The water bleeds off at the bottom, forcing its movement in the outer section of the system. The thermostatic insert closes the bleed at 4\u00b0C.<\/p>\n<p>The amount of water that comes out of the system depends on many variables such as:<\/p>\n<ul>\n<li>outside temperature<\/li>\n<li>length of external sections<\/li>\n<li>quality of insulation<\/li>\n<li>installation water temperature<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-11700 aligncenter\" src=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/11111.png\" alt=\"\" width=\"582\" height=\"286\" srcset=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/11111.png 503w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/11111-300x147.png 300w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/11111-18x9.png 18w\" sizes=\"auto, (max-width: 582px) 100vw, 582px\" \/><\/p>\n<p style=\"text-align: center;\">Figure 1 Installation diagram with automatic filling valve<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-11701 aligncenter\" src=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/22222.png\" alt=\"\" width=\"381\" height=\"380\" srcset=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/22222.png 304w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/22222-300x300.png 300w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/22222-150x150.png 150w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/22222-12x12.png 12w\" sizes=\"auto, (max-width: 381px) 100vw, 381px\" \/><\/p>\n<p style=\"text-align: center;\">Figure 2 Valve operating diagram<\/p>\n<p>In the picture shown, the upper element is open because the outside air temperature has dropped below 5 <sup>o<\/sup>C.

The thermostatic element located at the bottom opened because the temperature of the medium dropped below 3 <sup>o<\/sup>C. At the same time, the vacuum breaker opens allowing the refrigerant to flow out of the valve. When the medium reaches the valve at a temperature of 4 <sup>o<\/sup>C the thermostatic element will close the outlet.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-11704 aligncenter\" src=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/2-768x1024.png\" alt=\"108 iStop \u2013 Basic version \" width=\"512\" height=\"683\" srcset=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/2-768x1024.png 768w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/2-225x300.png 225w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/2-9x12.png 9w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/2.png 900w\" sizes=\"auto, (max-width: 512px) 100vw, 512px\" \/><\/p>\n<p style=\"text-align: center;\">Figure 3 108 iStop basic version<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-11705 aligncenter\" src=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/3-768x1024.png\" alt=\"\" width=\"514\" height=\"685\" srcset=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/3-768x1024.png 768w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/3-225x300.png 225w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/3-9x12.png 9w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/03\/3.png 900w\" sizes=\"auto, (max-width: 514px) 100vw, 514px\" \/><\/p>\n<p style=\"text-align: center;\">Figure 4 108 iStop extended version<\/p>\n<p>Which version to choose?<\/p>\n<ul>\n<li><strong>basic <\/strong>if the heat pump will be used as a<strong> source for heating<\/strong><\/li>\n<li><strong>extended<\/strong> if the pump will prepare <strong>low-pressure heating and cooling medium<\/strong>.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>CALEFFI is a European leader in the manufacture of top quality control and measurement fittings used for domestic and industrial applications in the heating, air-conditioning, sanitary and renewable energy sectors Heat pump protection The growth in popularity of heat pumps, including monoblock heat pumps, has contributed to the increasing popularity of the Caleffi 108 series anti-freeze valve.
