Heaters "OShA-R" are designed for use mainly in petroleum and gas industry in hazardous areas of inside and outside facilities of V-1a and V-1d (acc. to PUE ch. 7.3) for heating enclosures and boxes with EC&I and equipment that requires positive temperature for normal operation.
Explosion-proof heaters RIZUR-OShA-R are designed for heating and temperature maintenance in the enclosures, insulation jackets, block-boxes, and instrumentation rooms with equipment that requires specific temperature for stable and reliable service. Heaters RIZUR-OUR and RIZUR-OUR-PL for EC&I equipment are designed for the heating of the instrumentation that has condensation of moisture in the form of frost or ice appear inside at negative temperatures preventing the successful operation of the EC&I equipment, electronic devices, and LCD-elements.
Explosion-proof heaters RIZUR-ONP can be used for oil heating at the exit out of the well in the winter season, as well as for local heating of the freezing parts of the industrial pipelines, e.g. in the places of Xmas needle valves, pipe valves, etc. used in fuel-power complexes, oil, gas, chemical, and other branches of the industry. Thanks to the quality design and multilayer testing during the manufacturing process, including run-to-failure tests, explosion-proof heaters RIZUR-OShA-R, RIZUR-OUR, RIZUR-OUR-PL, RIZUR-ONP manufactured by OOO "NPO RIZUR" are defined by reliably stable operation and the absence of failures in the field conditions.
