Description
Product Summary
This Trenton walk-in freezer refrigeration system pairs the TEZ TEZA045L8HS2DF 4-1/2 HP low temperature scroll condensing unit with the TPLP TPLP314LES2DR2 pre-assembled low profile unit cooler. It is sized for a 12' x 16' walk-in freezer with an 8 ft ceiling held at -10°F, a common setup for restaurants, ice cream shops, butchers and grocers that need frozen storage.
This is a manufacturer match. We ran the box through Trenton's own Load Calculator and model selector: for a 12' x 16' x 8' freezer at -10°F with a standard box load of 13,314 BTU/h, Trenton selects this condensing unit and unit cooler together. With 95°F outdoor air on R-448A, Trenton shows the pair balancing at 14,025 BTU/h with a -20.5°F suction temperature and a 10°F coil temperature difference, so the system covers the box load with room to spare.
The TEZ condensing unit is Trenton's Generation D EZ-Line, built around a Copeland ZF13K4E scroll compressor in an outdoor cabinet on 208/230V 1-phase power. It comes with a receiver, a sealed liquid line filter drier and a sight glass, plus a factory electric defrost kit that times the defrost cycles for the unit cooler, and it is AWEF compliant on R-448A, R-449A, R-404A and R-507.
The TPLP unit cooler is Trenton's pre-assembled low profile coil for freezers. It ships with the thermostatic expansion valve and liquid line solenoid valve already mounted for R-407A, R-407C, R-448A and R-449A, runs on 208/230V with 3 EC SmartSpeed fan motors, and uses electric defrost with defrost termination and fan delay built in. The defrost kit on the condensing unit starts each defrost cycle.
Key Features
- Matched by Trenton: both units were selected together by Trenton's own Load Calculator for a 12' x 16' freezer, balancing at 14,025 BTU/h at 95°F outdoor air.
- Copeland scroll compressor: the ZF13K4E scroll in the TEZ unit runs quietly and efficiently, with a receiver, drier and sight glass built in.
- Pre-assembled unit cooler: the expansion valve and solenoid valve come mounted on the TPLP coil for a faster, cleaner install.
- Low profile EC fan coil: a slim ceiling-mounted coil with EC SmartSpeed motors saves headroom and power inside the box.
Frequently Asked Questions
What size walk-in freezer is this system for?
It is sized for a 12' x 16' walk-in freezer with an 8 ft ceiling held at -10°F under a standard load of 13,314 BTU/h. A box with heavy door traffic, warm product loading or glass doors can need more capacity, so call us at 1.888.509.3391 before ordering if your box is different.
How do I know the condensing unit and unit cooler are matched?
Walk-in refrigeration does not use AHRI matched-system numbers like home air conditioners. Each unit is rated on its own for AWEF, and the manufacturer matches them by capacity and temperature difference. This pairing comes straight from Trenton's Load Calculator, which selected the unit cooler to match this condensing unit.
How is defrost handled?
The electric defrost kit on the TEZ condensing unit starts defrost on a set schedule. The heaters in the TPLP coil melt the frost, the coil ends defrost on its own termination control, and the fans wait until the coil is cold again before restarting so no water is blown into the box.
Does this system need a licensed installer?
Yes. A split refrigeration system needs refrigerant piping, evacuation, charging and electrical work, so it should be installed by a licensed refrigeration technician following Trenton's installation instructions.
