A refrigerated merchandiser includes a case, a first case section defining a first product display area and a first air passageway having a first airflow inlet, a first airflow outlet, and a second airflow outlet, and a second case section having a glass panel through which a second product display area is visible. Moreover, the refrigerated merchandiser includes a fan positioned in the first air passageway to generate an airflow that is separated into a first airflow portion and a second airflow portion at or upstream of an evaporator. The first airflow portion is configured to flow through the evaporator and through the first airflow outlet. The second airflow portion is configured to bypass the evaporator via a bypass channel and flow through the second airflow outlet. The second airflow outlet is oriented to direct the second airflow portion over an exterior of the glass panel.

A refrigerated display cabinet includes a refrigeration loop including a compressor, a condenser, a throttling element and an evaporator; a main body comprising a storage space, the evaporator is for cooling the storage space and at least one of the compressor, condenser and throttling element are located outside of the storage space; and a fan arrangement located outside of the storage space, configured to direct air to disperse any build-up of gases located in a region surrounding the bottom of the refrigerated display cabinet.

A heat exchanger for a temperature controlled case is disclosed herein. A temperature controlled case includes a housing that defines a temperature controlled space. The housing includes a duct that receives circulated air. A heat exchanger is coupled to the housing and disposed within the duct. The heat exchanger includes an intake face at a non-perpendicular angle relative to an air flow direction in the duct immediately upstream of the heat exchanger.

A cabinet for storage of a heated food item has a base, top and opposing sides, the base, top and opposing sides defining an interior space which is accessible through opposing access apertures, An air movement means and air heating means draw air from the interior space of the cabinet, heat said air and produce an air curtain across a first one of the access apertures of the cabinet. A door is operable to reversibly close a second one of the access apertures to prevent ambient air from entering the interior space and heated air from egressing through said second access aperture. The air movement means circulate air within the interior space from the first one of the access apertures to one or more of: the opposing sides, and the top and the base of the cabinet.

A cabinet to hold and display a plurality of food items is provided. The cabinet includes a plurality of shelves that each include holding volumes that are accessible via an open front of the cabinet. The cabinet establishes a separate and dedicated air curtain across the opening into each holding volume and the temperature of the air forming each holding volume is separately controlled. Each shelf includes a digital display that can be controlled to display various parameters of the contents of the specific shelves or other material.

Condensation management systems and methods including a control unit and a plurality of auxiliary fan devices. The control unit includes fan, heating element and controller maintained by a housing, and a sensor. The auxiliary fan devices each include a fan electrically connected to the controller and that can be selectively installed to a refrigerated display case apart from the housing. The controller operates to prompt operation of the heating element, the fan, and the auxiliary fan devices in response to sensed information.

Systems and methods for deploying a defrost heater include a rod heater bracket that includes a body including a first edge and a second edge opposite the first edge. The bracket includes at least one L-shaped slot formed in the body. The L-shaped slot includes an opening along the first edge, and a groove located adjacent to the second edge and configured to retain at least a portion of a rod heater adjacent an evaporator of a refrigerated display case. The rod heater bracket includes a tab configured to be adjusted between an open position to allow access to the groove through the second edge and a closed position to block access to the opening between the second edge and the groove.
