Abstract: A system and process for performing a crimping operation by which a fitting is crimped to the end of a fluid conduit, and which automatically compensates for one or more variables that can lead to out-of-tolerance crimp diameters, particularly fitting spring-back and crimper deflection. The system and method use a device for inputting into the system a targeted crimp diameter for the fitting, and a crimper for crimping the fitting to the end of the fluid conduit. The crimper comprises a plurality of dies and an actuator for contracting the dies around the fitting to obtain the targeted crimp diameter for the fitting. The system and method further includes a unit for attaining the targeted crimp diameter by automatically compensating contraction of the dies for spring-back of the fitting during crimping and/or deflection of the crimper during crimping.

Abstract: A modular air conditioning system with adjustable capacity includes a cooling module, a heating module, and a blower module which can be assembled in any of a plurality of configurations, including a vertical downflow configuration, a vertical upflow configuration, or a horizontal configuration, using the same set of modules. The same set of modules can be operated over a range of cooling capacities by employing a condensing unit of the required capacity connected to the cooling module and by adjusting the airflow volume rate of air transported through the system. A movable restrictor plate is positioned in partial covering relation to a discharge opening of the blower module and is adjusted to achieve the required airflow volume rate.
