Finned Tubes
At KRN, we also specialize in Finned Tubes, which are manufactured by mechanically bonding fins onto tubes to maximize surface area. These tubes are widely used in air coolers, economizers, radiators, and heat recovery systems, delivering excellent performance in both heating and cooling applications.
Inner Grooved Tubes
Our Inner Grooved Tubes maximize internal heat transfer by increasing the surface area in contact with refrigerant or fluid. Widely used in air conditioning, refrigeration, and evaporator coils, they deliver higher efficiency and reduced refrigerant charge requirements.
Outer Grooved Tubes
Outer Grooved Tubes are engineered for improved air-side heat transfer by enhancing turbulence on the external surface. They are ideal for condensers, radiators, and fluid-to-air applications where increased efficiency and durability are essential.
Inner & Outer Grooved Tubes
These tubes combine both inner and outer grooves, offering superior heat transfer performance for high-demand HVAC, refrigeration, and industrial cooling systems. Their dual grooving makes them suitable for compact systems that require maximum efficiency in limited space.
Low & Medium Grooved Tubes
Low and Medium Grooved Tubes provide balanced performance where moderate enhancement is required. They are typically used in boilers, chillers, and medium-duty condensers, offering durability with controlled efficiency improvements.
