This is accomplished by combining heating elements, vessel, insulation, terminal enclosure, mounting brackets and inlet and outlet connections into a complete assembly. Made from NPT screw plug heater assemblies mated with a pressure vessel (tank), circulation heaters are designed to heat forced-circulation air, gases or liquids. Ideal for either in-line or side-arm operations, these assemblies direct fluids past FIREBAR or WATROD heating elements, to deliver fast response and even heat distribution. Watlow meets virtually all your circulation heater assembly needs with made-to-order units. These units can be made from a wide range of heating element sheath materials, wattages, vessel sizes and materials, pressure ratings, terminal enclosures and controls.<\/p>\n<p>For full product details and a complete list of related downloads click <a href=\"https:\/\/www.watlow.com\/Products\/Heaters\/Circulation-Heaters\/WATROD-FIREBAR-Circulation-Heaters\">here<\/a>.<\/p>\n<p>&nbsp;<\/p>\n<table width=\"100%\">\n<thead>\n<tr>\n<th colspan=\"1\" valign=\"middle\">Description<\/th>\n<th valign=\"middle\">Information<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td align=\"left\">Material<\/td>\n<td align=\"left\">316 Stainless Steel<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Operating Temperature &#8211; C<\/td>\n<td align=\"left\">650<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Operating Temperature &#8211; F<\/td>\n<td align=\"left\">1200<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Watt Densities<\/td>\n<td align=\"left\">18.6<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Watt Densities<\/td>\n<td align=\"left\">120<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<table width=\"100%\">\n<thead>\n<tr>\n<th colspan=\"1\" valign=\"middle\">Description<\/th>\n<th valign=\"middle\">Information<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td align=\"left\">Material<\/td>\n<td align=\"left\">Alloy 800\/400<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Operating Temperature &#8211; C<\/td>\n<td align=\"left\">870<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Operating Temperature &#8211; F<\/td>\n<td align=\"left\">1600<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Watt Densities<\/td>\n<td align=\"left\">18.6<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Watt Densities<\/td>\n<td align=\"left\">120<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<table width=\"100%\">\n<thead>\n<tr>\n<th colspan=\"1\" valign=\"middle\">Description<\/th>\n<th valign=\"middle\">Information<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td align=\"left\">Material<\/td>\n<td align=\"left\">N\/A<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Operating Temperature &#8211; C<\/td>\n<td align=\"left\">175<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Operating Temperature &#8211; F<\/td>\n<td align=\"left\">350<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Watt Densities<\/td>\n<td align=\"left\">18.6<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Watt Densities<\/td>\n<td align=\"left\">120<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<table width=\"100%\">\n<thead>\n<tr>\n<th colspan=\"1\" valign=\"middle\">Description<\/th>\n<th valign=\"middle\">Information<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td align=\"left\">Material<\/td>\n<td align=\"left\">Steel<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Operating Temperature &#8211; C<\/td>\n<td align=\"left\">400<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Operating Temperature &#8211; F<\/td>\n<td align=\"left\">750<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Watt Densities<\/td>\n<td align=\"left\">18.6<\/td>\n<\/tr>\n<tr>\n<td align=\"left\">Maximum Watt Densities<\/td>\n<td align=\"left\">120<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<h3 style=\"background: white;\"><span style=\"font-family: Helvetica, sans-serif; color: #3dcd58;\">WATROD\u2122 and FIREBAR\u00ae Heaters Designed to Heat Forced-Circulation Air, Gases or Liquids<\/span><\/h3>\n","protected":false},"featured_media":141957,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[19397,19425,1430,17719],"product_tag":[],"class_list":{"0":"post-144635","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-heaters-sg","7":"product_cat-circulation-heaters-sg","8":"product_cat-products-eng-sing","9":"product_cat-watlow-featured-products-and-software-sg","11":"first","12":"instock","13":"shipping-taxable","14":"product-type-simple"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.2 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Screw Plug Circulation Heaters | Eurotherm Limited<\/title>\n<meta name=\"description\" content=\"Screw Plug Circulation Heaters | Circulation heaters provide a ready-made means to install electric heating with a minimal amount of time and labor.
