ABSTRACT:
A fixture for supporting a heat exchanger coil within a tube expander apparatus. The back wall of the fixture contains a series of spaced apart vertically disposed stationary slats. A moveable frame is slidably mounted in the back wall which contains a series of vertically disposed spaced apart moveable slats that are interspaced between the stationary slats. The slats coact to present an adjustable flat support surface to a coil mounted in the fixture that can be adjusted to accommodate different size coils. The front door of the fixture contains a similarly adjustably wall that coacts with the back wall to fully support a coil in the fixture as the tubes of the coil are being expanded.
