Abstract: In one instance, a cooling unit for cooling a refrigerated room includes a fan base and a fan guard that both twist and rotate to change pitch thereby allowing the cooling unit air to be directed in many directions as desired. The fan base has a flange portion and a conduit portion. The conduit portion of the fan base mates with an opening in a conduit member of the fan guard. The opening in the fan guard is sized and configured to form an interference fit with at least a portion of a conduit portion of the fan base while allowing rotation of the fan guard relative to the fan base about the longitudinal axis. The second longitudinal end of the fan-guard conduit member is at least partially angled to allow the rotation about a lateral axis in order to pitch the direction of the grill front wall.

Abstract: A condenser unit housing of a refrigeration system has an outer walls and a top cover. An opening formed in one of the outer walls and framed by the top cover and sidewalls, the opening having a width W1 between the sidewalls. The housing includes a swing gate positioned within the opening when in a closed position and contacting the top cover when in an open position. The swing gate includes first rods having a width W2 less than the width W1, second rods coupled to the first rods, the second rods extending in a direction different than the first rods, and a pivot rod. The second rods include a straight section and a curved section. The pivot rod is coupled to the curved section and has a width W3 greater than the width W1. The pivot rod is below the top cover in both the open position and the closed position. Other embodiments are presented.
