Kramer KL6E142DDASC Low Temperature Electric-Defrost Unit Cooler
The Kramer KL6E142DDASC is a low-profile electric-defrost unit cooler for low-temperature walk-in freezers. It delivers 16,600 BTUH on R448A or R449A refrigerant at a -20°F saturated suction temperature and a 10°F TD, moving 2,325 CFM with three electronically commutated fan motors. Sold as the evaporator only, it completes a walk-in freezer system when matched with a Kramer low-temperature condensing unit.
Capacity, Defrost, and Matched Condensing Unit
At -20°F SST and a 10°F TD the KL6E142DDASC produces 16,600 BTUH on R448A or R449A (14,200 BTUH on R404A), suited to a walk-in freezer held near -10°F. Freezer coils frost faster than off-cycle air can clear, so this unit uses timed electric defrost — about 3,300 watts of heaters on a 230V circuit — rather than air defrost.
This is the indoor evaporator only. To build a complete walk-in freezer system it pairs with a matched Kramer low-temperature condensing unit — the KL6E142DDASC is factory-matched to the 5 HP KFO500L4SDB condensing unit. Order the condensing unit separately, or contact Budget Heating for a complete matched-system quote.
Ideal for: large industrial and distribution freezers, processing plants, and cold storage.

Frequently Asked Questions
What size freezer does the KL6E142DDASC serve?
It is a three-fan low-profile electric-defrost unit cooler rated 16,600 BTUH on R448A or R449A at -20°F SST and 10°F TD, for large industrial and distribution freezers near -10°F.
Is a condensing unit included?
No. This is the evaporator only; it pairs with a matched outdoor low-temperature condensing unit sold separately.
Which condenser matches the KL6E142DDASC?
It matches the 5 HP KFO500L4SDB low-temperature condensing unit.
How much airflow and how many fans?
Three EC fans move about 2,325 CFM in a draw-through pattern to hold temperature evenly across a large freezer.
What is the electric-defrost heater rating on the KL6E142DDASC?
About 3,300 watts, drawing roughly 14.3 amps on a 230V heater circuit during the timed defrost cycle.
Is the KL6E142DDASC NSF and UL listed?
Yes. Like the KL6 series it is NSF compliant and UL/cUL listed, with an embossed aluminum casing designed for flush ceiling mounting.
