Description
Product Summary
This Trenton walk-in cooler refrigeration system pairs the TEZ TEZA015H8HS2DB 1-1/2 HP medium temperature scroll condensing unit with the TPLP TPLP214MAS1DR2 pre-assembled low profile unit cooler. It is sized for a 12' x 16' walk-in cooler with an 8 ft ceiling held at 35°F, a common setup for restaurants, convenience stores, florists and small grocers.
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' cooler at 35°F with a standard box load of 13,887 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 14,535 BTU/h with a 24.8°F suction temperature and a 9.7°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 ZS13KAE 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, 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. It ships with the thermostatic expansion valve, liquid line solenoid valve and thermostat already mounted for R-407A, R-407C, R-448A and R-449A, so there are fewer loose parts on the job. It runs on 115V with 2 EC SmartSpeed fan motors and uses air defrost, the normal choice for a cooler held above freezing.
Key Features
- Matched by Trenton: both units were selected together by Trenton's own Load Calculator for a 12' x 16' cooler, balancing at 14,535 BTU/h at 95°F outdoor air.
- Copeland scroll compressor: the ZS13KAE 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 cooler is this system for?
It is sized for a 12' x 16' walk-in cooler with an 8 ft ceiling held at 35°F under a standard load of 13,887 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 the box temperature controlled?
The thermostat opens and closes the liquid line solenoid valve. When the box reaches temperature, the solenoid closes, the system pumps down and the compressor shuts off on its low pressure control. When the box warms up, the solenoid opens and the compressor restarts, while the expansion valve meters refrigerant into the coil.
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.
