Heaters

Heat exchangers with heating coils or stationary tanks with internal heating

We manufacture large-volume single-wall, double-wall, and tubular heaters for various media, in compliance with customer requirements and applicable standards. A heater may function either as a heat exchanger with heating coils or as a stationary tank with internal heating. In both cases, it serves to raise the temperature of the medium without changing its phase. These heat exchangers consist of a shell and multiple layers of counter-wound spiral tubes. Heaters are produced from various materials suitable for the operating environment and media. The delivery of the heater includes complete accompanying documentation with all required certificates and test reports. The design of heaters as heat exchangers may feature fixed tubesheets, floating heads, or U-tubes.

These constructions can include shell expansion compensators, clad tubesheets, and the installation of various types of baffles to enhance efficiency. We also supply components of heaters, such as tube bundles (straight or U-tubes) with clad or overlayed tubesheets. Tube-to-tubesheet joints can be strength-welded, strength-expanded, or a combination of both. The delivery of the heater includes complete accompanying documentation with all required certificates and test reports, including the pressure vessel passport.
