The recently introduced Niagara trailer refrigeration series, called “the first major evolution” of Carrier Transicold’s X-Series, features a modern new look. The single-temperature Niagara units build on the current X-Series’ features, introduced in 2000.

The new reefers feature a major exterior redesign. Panel doors are made of DuraShell 2 material, a thermoplastic olefin composite. It has structural integrity comparable to the X-Series’ original DuraShell material, Carrier says, but with triple the impact strength, double the UV light
resistance, 50% better thermal stability, and 20% better heat resistance. An optional chrome package is also offered.

The Niagara’s improved sound quality is said to come from design changes and use of a quieter gearbox. The DuraShell 2 twin-sheet panel construction, acoustic foam on the interior surfaces, and integrated door seals help contain sound output. The redesigned grille’s wider openings
reduce airflow resistance, helping to further improve sound quality. For additional sound reduction, an optional composite bottom panel is available.

Technicians will appreciate improved access to mechanical parts, the maker says. Uniquely, Niagara models have hinged side doors that open all the way to the top, providing total access with the flip of a single latch on each side door. The front panels swing open from the center with a
single latch release.

Four models will succeed the current single-temperature units when the Niagara series goes into full production later this year: the Niagara 2500A, Niagara 2100A, Niagara 2100 and Niagara 1800, replacing the Ultima XTC, Ultra XTC, UltraXT, and Extra XT respectively. The Niagara model numbers relate to capacity in BTUs at the deep-frozen setpoint.
