Everything you need to get things hot
In addition to boilers for bathrooms and kitchens or for supplying entire houses with hot water (white goods), DEW also supplies heating elements for industrial hot water storage tanks, cartridge heaters and boiling water supply systems. Most of these devices are designed to meet special requirements, and they are in demand particularly with industry suppliers and large-scale consumers of hot water. They are used in preheaters among others.
Specific application scenarios include e.g. open cast mine excavators, for which a constant basic operating temperature needs to be ensured at all times, hydraulic systems in which the temperature of the hydraulic fluid needs to be regulated, and solutions for heating outdoor boilers – all from the point of view of efficient use of resources. Manufacturers of heat pumps are increasingly becoming more and more important customers for our instantaneous heaters, as this combination of technologies delivers a much better environmental balance than conventional hydraulic variants.
Suitable products
Insulated screw-in heaters
Insulated screw-in heaters are used primarily inside enamelled buffer tanks – for example in hot water boilers. As immersion heaters, they are used for direct heating of liquid media. Clients include boiler manufacturers, installers and companies from the solar industry. Galvanic isolation reduces electrochemical stress corrosion, which would otherwise lead to the destruction of the …
Non-insulated screw-in heaters
Screw-in heaters from DEW are the most effective way to heat gaseous and liquid media directly – including in hot water storage tanks and heating boilers. All the important parameters like the installation length, power output and the type of medium that is to be heated can be individually specified. We always carry the standard …
Insulated flange heaters
Our insulated flange heaters have been specially developed for use in enamelled tanks and boilers. The advantage for you: thanks to the galvanic isolation, the risk of electrochemical corrosion is reduced to a minimum. Clients for our flange heaters include leading boiler manufacturers among others. Private customers and installers can also source spare parts for …
Non-insulated flange heaters
Non-insulated flange heaters are the ideal solution wherever high energy density is required in smallest spaces. Here, the field of application ranges from small steam generators to large industrial plants. Among the largest customer groups for DEW are industrial plant manufacturers. Design The shaped, densely compacted heating elements are welded or brazed into the flanges, …
Instantaneous heaters
Instantaneous heaters are used both in industrial applications and in the home. They offer the advantage that customers do not need to manufacture separate housings. After delivery from DEW, all that needs to be done is to make the hydraulic and electrical connections. Design There are three different basic designs of instantaneous heaters: Installation information/temperature …
