Trenton TEP extended profile evaporators

TEP is Trenton Refrigeration's extended profile unit cooler line for walk-in coolers and freezers. Seven application classes span high temperature (25 F and up, 7 FPI), medium temperature (10 to 35 F), low temperature (-40 to 0 F) in 6 and 4 FPI, and three CO2 classes, with six defrost types and four voltages: 208-230 V and 460 V, single and three phase.

The number after TEP is the nominal capacity in thousands of BTU/h. Unlike the other Trenton lines, it carries no fan-count digit.

Documentation history (2025 to 2026)

Generations D and E

The generation D and E bulletin (September 2025) prints both generations' data, defines D as A1 refrigerant AWEF compliant and E as A2L refrigerant AWEF compliant, and carries the CO2 classes, on which the 3 pipe hot gas defrost options are not available. The generation E bulletin (August 2026) is E only: it defines E as A2L and A1 refrigerant, adds an A2L refrigerant detection system and a positive slope hinged drain pan, and lists no CO2 class. Its legend names the medium and low temperature classes only, while its tables also print the high temperature class.
