Kramer KL6E105DDASC Low Temperature Electric-Defrost Unit Cooler
The Kramer KL6E105DDASC is a low-profile electric-defrost unit cooler for low-temperature walk-in freezers. It delivers 12,400 BTUH on R448A or R449A refrigerant at a -20°F saturated suction temperature and a 10°F TD, moving 1,550 CFM with two 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 KL6E105DDASC produces 12,400 BTUH on R448A or R449A (10,500 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 2,250 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 KL6E105DDASC is factory-matched to the 4 HP KFO400L4SDB condensing unit. Order the condensing unit separately, or contact Budget Heating for a complete matched-system quote.
Ideal for: large frozen-storage and distribution freezers and processing operations.

Frequently Asked Questions
What is the KL6E105DDASC built for?
It is a two-fan low-profile electric-defrost unit cooler rated 12,400 BTUH on R448A or R449A at -20°F SST and 10°F TD, for large frozen-storage and distribution freezers near -10°F.
Which condensing unit pairs with the KL6E105DDASC?
Kramer matches it with the 4 HP KFO400L4SDB low-temperature condensing unit, sold separately.
What refrigerants does the KL6E105DDASC support?
It is rated on R448A and R449A (12,400 BTUH) and on R404A (10,500 BTUH); R448A and R449A are the current-generation replacements for R404A.
Why is electric defrost used instead of air defrost?
A freezer coil at these temperatures accumulates frost that box air cannot melt, so about 2,250 watts of electric defrost heaters clear the coil on a timed cycle.
What is the fins-per-inch and casing on the KL6E105DDASC?
It is a 6 fins-per-inch coil in an embossed aluminum casing with baffled fan sections, NSF compliant and ceiling-mounted.
What electrical service does the coil require?
Per the Kramer data sheet it is 208-230V with EC fan motors near 1.0 amp and a 15 amp minimum circuit ampacity, plus a separate 230V electric-defrost heater circuit.
