Immersion Heaters type J.I.S.
Screw type elements are assembled from 3 main components: The heating element (tubular element), the screw connection and the connection box (optional). The tubular elements are by means of TIG welding or soldering mounted in the screw coupling. By this method a compact heating element is created with an optimum heat transfer to the medium.
Application
For correct operation, the heating element must be screwed direct into the reservoir. To prevent damage to the element, an application should be made to prevent the element in operation to be running “dry”. The temperature of the medium to be heated can be set with an adjustable thermostat, which is optionally available. If this option is not used, an external safety provision is required.
Applicable only in non-hazardous areas.
Construction
Screw type elements are used for the heating of water, oil and an array of other fluid or gaseous media. The elements can be delivered wit- or without temperature control and/or safety in the connection box. For the most common applications we run a line of standardised screw type heating elements. A line of Explosion proof elements is available also.
Types of this product
Screw-in elements of nickel plated copper are designed to heat up water in hot water tanks or open reservoirs.
