Finned Tubular Heaters – Efficient Air & Gas Heating Solution
Caldor’s finned tubular heaters are engineered to deliver highly efficient and reliable air and non-corrosive gas heating for both industrial and commercial environments. Leveraging a precision-designed finned surface and engineered dissipation channels, these heating elements ensure enhanced convective heat transfer, maximizing thermal performance while maintaining stable operating temperatures across varying airflow conditions.
The robust design of Caldor’s finned heaters makes them suitable for a wide range of demanding applications — from heavy industrial processes requiring high-capacity airflow heating to commercial and public building systems that demand precise temperature control. Their performance and versatility make them an ideal choice for systems that require consistent, uniform heat distribution over extended operation periods.
Durability and Application-Specific Material Selection
Caldor offers a wide variety of high-quality sheath materials for finned tubular heaters, each selected to meet specific performance and environmental requirements. Material choices ensure long-term durability and resistance to oxidation, humidity, and thermal stress:
Stainless Steel Options (AISI Series):
AISI 304 — economical and suitable for general environments and food processing applications
AISI 321 — suited for high-temperature and long-duration operation, with carbide precipitation resistance
AISI 316 / 316L — excellent chemical resistance, especially for aggressive environments
AISI 316Ti (316T) — enhanced high-temperature stability for thermal processes and dryers
AISI 329 (Duplex) — combines mechanical strength with superior corrosion resistance
High-Performance Alloys – Incoloy:
Incoloy 800 / 825 — strong resistance to oxidation and high temperatures, ideal for chemical and petrochemical environments
Incoloy 850 / 900 — designed for extreme temperature and environmental conditions such as steam systems and high-pressure processes
The careful selection of materials, combined with Caldor’s engineering expertise, ensures that finned tubular heaters deliver robust performance and longevity in the most challenging applications.
