In addition to lower operating pressures, the use of hot oil instead of water and steam at high temperatures has several other advantages, including:
Small volume
Saving fuel
Easy to install and set up
Easy navigation and operation
Unlimited heat capacity
No risk of corrosion and freezing damage
Much less noise than steam boilers
No heat loss through condensation
No need for preliminary water feeding operations
Less time to reach the desired temperature than steam boilers
Accurate and safe design of hot oil boilers is crucial for optimum use in high temperature applications. Hot oil heating systems manufactured by Dub Industries are designed and manufactured in accordance with international standards API and DIN4754. These systems are in the form of integrated coils (OIL TUBE) and are available in horizontal and vertical models at capacities of 100,000 to 6,300,000 kcal / hr. All manufacturing operations are performed under the direct supervision of the company's quality control inspectors.
