Kramer KL6E035DDASC Low Temperature Electric-Defrost Unit Cooler
The Kramer KL6E035DDASC is a low-profile electric-defrost unit cooler for low-temperature walk-in freezers. It delivers 4,000 BTUH on R448A or R449A refrigerant at a -20°F saturated suction temperature and a 10°F TD, moving 800 CFM with one electronically commutated fan motor. 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 KL6E035DDASC produces 4,000 BTUH on R448A or R449A (3,500 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 1,125 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 KL6E035DDASC is factory-matched to the 1.3 HP KFO130L4SDA and the 1.5 HP KFO160L4SDA condensing unit. Order the condensing unit separately, or contact Budget Heating for a complete matched-system quote.
Ideal for: small walk-in freezers in restaurants, ice cream shops, convenience stores, delis, and bakeries.

Frequently Asked Questions
What is the KL6E035DDASC evaporator used for?
It is a low-profile electric-defrost unit cooler for low-temperature walk-in freezers, rated 4,000 BTUH on R448A or R449A at -20°F SST and a 10°F TD, for a box held near -10°F.
Does this listing include the condensing unit?
No. This is the indoor evaporator (unit cooler) only. It requires a matched outdoor low-temperature condensing unit, sold separately, to form a complete freezer system.
Which condensing units match the KL6E035DDASC?
Kramer matches it with the 1.3 HP KFO130L4SDA and the 1.5 HP KFO160L4SDA low-temperature condensing units (single- or three-phase).
Why does this evaporator use electric defrost?
Below freezing, frost builds on the coil faster than off-cycle air can melt it, so a low-temperature coil uses electric defrost heaters — here about 1,125 watts — on a timed cycle to clear frost.
What electrical does the KL6E035DDASC need?
Per the Kramer data sheet it is a 208-230V unit: single-fan EC motor drawing about 0.5 amps, with a 15 amp minimum circuit ampacity and 20 amp maximum overcurrent protection, plus a 230V electric-defrost heater circuit.
How many fans does the KL6E035DDASC have?
One EC fan moving about 800 CFM in a draw-through pattern, suited to a small freezer box.
