Standard DutyHot Water Coils
Coils are designed to withstand 250 psi maximum operating pressures and a maximum fluid temperature of 300° F for standard duty copper tube coils. Higher limits are available depending on coil construction and/or materials used. Expedited 3, 5 day or 24 hour shipping available
Coils are constructed with plate fin, die-formed aluminum or copper with self-spacing collars. Material thickness designed to match or exceed the OEM equipment or designed to your specifications.
All tubing and return bends are manufactured with seamless copper conforming to ASTM B75 and ASTM B251. Tubes are mechanically expanded to form an interference fit with fin collars.
All manifolds are constructed from seamless copper conforming to ASTM B75 and ASTM B251. Each return manifold has a factory installed air vent located at the highest point on the face of the manifold. All core tubes evenly protrude into the inside diameter of the manifold no more than a 1/8”.
All brazed joints utilize high temperature filler metals. Manifold connections are brazed with filler metal containing at least 5% silver.
Coils are pressurized with a minimum of 350 psi air pressure and completely submerged in water.
Please notify us upon quote request if you require higher design requirements as we can supply a heavy commercial grade coil or industrial coil to meet any requirement.
*Higher design requirements can be met with our Heavy Commercial or Industrial Coils for high pressure or corrosive environments.
