A pressure and/or temperature relief header for use in an HVAC heat transfer coil includes a main body adapted to be secured to bends in fluid coils of the HVAC fluid tube system. The main body includes holes in alignment with holes formed in the bends to enable liquid to pass from the bends into the expansion relief header. The expansion relief headers include a pressure release valve that automatically opens, preferably in response to pressure exceeding a predetermined threshold value or temperature falling below a predetermined value, to release liqui...


1. An HVAC heat transfer coil with a relief component, the coil comprising: a plurality of liquid tubes;a plurality of bends to connect ends of adjacent liquid tubes together to form a liquid passage therebetween;one or more expansion relief headers, wherein each of the expansion relief headers is to connect to a plurality of aligned bends, wherein the bends include holes in alignment with holes formed in the expansion relief header to enable liquid to escape from the bends into the expansion relief header;a pressure relief valve mounted on an external s...
