Quality
Super Radiator Coils has been manufacturing coils since 1928, and recognizes the importance of providing quality products to our customers. Materials used in our coils are high quality, and tubes and pipes are mill certified and meet ASTM/ASME standards.
Our engineers work closely with the customer to understand how the coil will be applied. They create designs and designate inspections at critical points during the coil's assembly and testing. The engineer stays closely involved and is available to answer questions as the coil is fabricated.
Shop personnel examine coil components, tubes, and fins as each coil is assembled. In-house inspectors review the coils at key stages and check that any special instructions are followed. Once the coil is fully assembled it receives a final inspection.
Each coil is leak-tested just before shipping. Our standard method of testing is charging the coil with dry nitrogen at a minimum of 250 PSIG and placing the coil under water. The dry nitrogen helps to dehydrate the coil. Higher test pressure can be used depending on the strength of the coil's materials, or as required to meet certifications such as UL and CSA.
Super Radiator Coils can provide a higher degree of non-destructive examinations when the severity of the application warrants it. They include radiographic, ultrasonic, and liquid penetrate testing. These services are performed by a level II SNT-TC-IA inspector.
We also offer other leak-test methods such as hydrostatic, vacuum drop, and sniffer tests. If you have such leak test requirements or wish to discuss other methods, contact the nearest Super Radiator Coils facility.
