Product details

Description

Product Summary

This Bohn walk-in cooler refrigeration system pairs the BCH0005MBACZA0000 1/2 HP medium temperature condensing unit with the BEL0045AS6AMAB0405 low profile unit cooler. It is sized for a 6' x 6' walk-in cooler with an 8 ft ceiling held at 35°F, the classic setup for restaurants, convenience stores, florists and small grocers.

We did not pair these two units by guesswork. The match comes straight from Heatcraft, the company that builds Bohn equipment, using its Quick Selection tool. For a 6' x 6' x 8' box at 35°F, Heatcraft calculates a typical load of 4,986 BTU/h and recommends exactly this condensing unit and unit cooler. With 95°F outdoor air and a +25°F suction temperature on R-448A, Heatcraft shows the two units balancing at 7,020 BTU/h at a 10.8°F coil temperature difference. The Heatcraft selection sheet for this system is in the Documents section below.

The BCH condensing unit uses a Copeland scroll compressor and a microchannel condenser coil in a compact horizontal air discharge cabinet built for outdoor installation on 208/230V single-phase power. The low profile unit cooler mounts to the ceiling of the box, runs on 115V with an energy-saving 2-speed EC fan motor, and uses air defrost, which is the normal choice for a cooler held above freezing. Both units meet the DOE minimum AWEF requirements for walk-in coolers.

The unit cooler is the B0405 version, so the thermostatic expansion valve (TXV), liquid line solenoid valve and room thermostat come factory mounted for R-448A and R-449A. That means fewer loose parts on the job and a cleaner, faster install.

The condensing unit is the A0000 standard base. It ships without a factory defrost timer (Heatcraft sells that separately as option A0100), and your installer will set up the cooler's off-cycle defrost with the room controls.

Key Features

  • Manufacturer-matched pairing: both units were selected by Heatcraft's own Quick Selection tool for a 6' x 6' cooler, and the selection sheet is included.
  • Efficient scroll compressor: the Copeland scroll and microchannel coil deliver 7,020 BTU/h at 95°F ambient while meeting DOE AWEF minimums.
  • Low profile unit cooler: a slim ceiling-mounted coil with a 2-speed EC fan motor saves headroom and power inside a small box.
  • Modern refrigerant: rated for R-448A and R-449A, the lower-GWP replacements for R-404A in walk-in coolers.

Frequently Asked Questions

What size walk-in cooler is this system for?

Heatcraft selected this pair for a 6' x 6' walk-in cooler with an 8 ft ceiling held at 35°F under a typical load. 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 under AHRI 1250, and the manufacturer matches them by capacity and temperature difference. This pairing is Heatcraft's own recommendation, and its selection sheet is linked in the Documents section.

How is the box temperature controlled?

A room 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 switch. When the box warms up, the solenoid opens and the compressor restarts. The TXV meters refrigerant into the unit cooler coil the whole time.

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 the Heatcraft installation manuals in the Documents section.
