This listing is for RCU-4, a Trenton TMS060MB-HT4A-Z1SB50 outdoor air-cooled condensing unit from Trenton’s TMS series, purpose-built for reliability and efficiency in demanding refrigeration environments.
This model features a 6 horsepower Copeland Z-series scroll compressor, optimized for high/medium-temperature applications such as walk-in coolers, refrigerated warehouses, or food-processing systems. The “H” in the model code designates high/medium-temperature operation, while the “8” identifies it as part of Trenton’s multi-refrigerant platform—supporting R404A, R407A, R407C, R448A, R449A, and R507. The “T4” indicates a 460 V 3-phase 60 Hz power supply, standard for heavy-duty commercial installations.
Its galvanized steel housing is weather-resistant and service-friendly, with removable panels and top-discharge condenser fans. The unit’s compact, durable construction makes it well-suited for rooftop or ground-mounted setups.
