About this item

Product Details

Put refrigerated products in full view without giving up dependable cold holding.

The True GDM-26 combines a Low-E glass swing door, LED lighting, five adjustable shelves, and a factory-designed 33°F to 38°F temperature range in a 30-inch-wide cabinet. If its one-door layout fits your sales floor or service area, it keeps packaged food and beverages visible, organized, and easy to reach. See how commercial equipment financing could make this upgrade easier to budget.

Before ordering, confirm that the True GDM-26 matches the products being displayed, the available floor space, the electrical supply, and the door-swing path. This merchandiser is listed under NSF/ANSI Standard 7 for the storage or display of packaged and bottled products.

Planning checks for the True GDM-26 refrigerated merchandiser
Planning check What to verify
Approved use Refrigerated storage and display of packaged or bottled products
Temperature range 33°F to 38°F under the manufacturer’s specified operating conditions
Cabinet size 30 inches wide, 29⅞ inches deep, and 78⅝ inches high
Handle allowance Published cabinet depth excludes approximately 1⅝ inches for the handle
Electrical service 115V, 60 Hz, single-phase, 5.4 amps, and a NEMA 5-15P plug connected to a dedicated 15-amp outlet
Shelving Five adjustable PVC-coated wire shelves measuring 25 11/16 inches long by 23¼ inches deep
Refrigeration Self-contained, bottom-mounted system using R290 hydrocarbon refrigerant

The official True GDM-26 specification sheet controls the final dimensions and requirements. Confirm the complete model number and exterior finish on the order because True offers more than one finish configuration.

The published depth doesn’t include the handle, and the installation needs room for the door to open fully. Measure the delivery path, final footprint, handle projection, and door swing before purchase. Level the cabinet after placement so it remains stable and the self-closing door can operate correctly.

The bottom-mounted condensing unit keeps service access near floor level and permits storage on top of the cabinet. Don’t block the lower grille or crowd the service area. Keep the True GDM-26 away from excessive heat, airborne grease, and conditions outside the manufacturer’s limits.

Connect the factory-installed cord directly to the specified outlet, and don’t use an extension cord. Because the circuit contains R290 hydrocarbon refrigerant, sealed-system service requires a technician qualified for that refrigerant and the applicable safety requirements.

The True GDM-26 works best when cold air can circulate around the merchandise and the self-closing door can seal without interference. A tightly packed cabinet may look full, but blocked airflow can produce uneven product temperatures.

  • Keep packages clear of internal air passages.
  • Distribute products across the shelves instead of concentrating the load in one area.
  • Make sure every shelf clip is fully seated before loading merchandise.
  • Keep labels facing forward so products remain easy to identify through the glass.
  • Prevent cartons, bottles, and shelf accessories from obstructing the door.

The True GDM-26 is engineered to maintain 33°F to 38°F. Air temperature may rise briefly after repeated door openings or warmer-product loading. Allow recovery time, and verify product temperature with an appropriate calibrated thermometer.

If the cabinet remains too warm, confirm that it has power, the door closes completely, the gasket seals, merchandise isn’t blocking airflow, and the condenser area is clean and unobstructed. Avoid repeated control adjustments or an assumed “reset.” If the True GDM-26 doesn’t return to its specified range, arrange qualified service.

Condensation can form when humid air reaches the cold glass or enters through an incomplete seal. Frequent openings, a dirty or damaged gasket, merchandise holding the door open, and high room humidity can increase it. Wipe away moisture, inspect the gasket, confirm full closure, and reduce unnecessary openings. Investigate persistent interior moisture or water accumulation using the True manual.

Clean the glass, shelves, gasket, cabinet drain, and condenser area according to True’s instructions. Disconnect power when directed, and avoid tools or chemicals that could damage the cabinet. Compare other True one-section glass-door merchandising refrigerators if this model’s footprint, layout, or approved use doesn’t fit the operation.

True GDM-26 FAQs

What temperature should the True GDM-26 maintain?
It is designed to maintain 33°F to 38°F under its specified operating conditions. Verify product temperature, and follow the manufacturer’s instructions before changing settings.
What products can be stored in the True GDM-26?
Use it for packaged and bottled refrigerated products. Its NSF/ANSI Standard 7 listing doesn’t establish approval for uncovered food.
Does the True GDM-26 need a dedicated electrical outlet?
Yes. It requires a dedicated 115V, 60 Hz, single-phase, 15-amp outlet and a NEMA 5-15P connection. Don’t use an extension cord.
Why is my True GDM-26 not cooling properly?
First check power, door closure, the gasket, product loading, airflow, and the condenser area. If the cabinet doesn’t recover to 33°F to 38°F, request qualified service.
What causes condensation on the True GDM-26 glass door?
Warm, humid air contacting the cold door can cause condensation. Frequent openings, high room humidity, gasket problems, or an obstructed door can increase it. Correct those conditions, and request service if moisture persists.
