Quality Engineers examine coil components, tubes, and fins as each coil is assembled. In-house inspectors review the coils at key stages and check that all special instructions are followed. Once the coil is fully assembled, it undergoes a final inspection. Each coil is leak-tested to avert any leakages in the coil. Our standard method for testing is to charge the coil with dry nitrogen at a minimum of 350 - 450 PSIG for small size coils and 500 - 550 psig for large size coils and later on placing the coil under water. The dry nitrogen helps to dehydrate the coil. Higher test pressure can be used depending on the strength of materials used in that particular coil.
