1 NEXT-GEN ALL-TEMP Catalog KM-KLX-0817C NEXT-GEN ALL-TEMP LOW PROFILE UNIT COOLER AIR, ELECTRIC & HOT GAS DEFROST MODELS 2,700 to 45,900 BTUH SMALL TO MEDIUM WALK-INS COOLER & FREEZER APPLICATIONS 2 NEXT-GEN ALL-TEMP Features Kramer Low Profile Unit Coolers feature an air draw-through design and are available in air, electric and hot gas defrost configurations. We’ve taken these all-purpose unit coolers to the next level with the release of the Next-Gen All- Temp models. The units feature a new fan guard design and deep draw venturi to achieve optimal airflow, easy access for serviceability, and can be used with multiple refrigerants
SIZES ELECTRICAL There are a wide array of sizes available with capacities Available for 115V, 115-230V (Air Defrost EC motor only), ranging from 2,700 to 45,900 BTUH at a 10° TD. One 208/230V and 460V (see pages 5 through 9). A large through six fan models are available with air flow electrical compartment is supplied internal to the unit to spanning a range of 800 to 4,650 CFM. house the electrical components and is easily accessible by removing the slide out end panel. All models are UL HOUSING and cUL listed and are available for 60 Hz or 50 Hz The embossed aluminum casing is lightweight yet applications
durable. Each fan section is baffled to prevent short cycling of the discharge air. The units are designed to AIR DEFROST mount flush to the ceiling and are compliant with NSF Air Defrost models (KL6A) are designed for use in requirements. The top pan includes 1/2” wide slotted coolers 35°F and warmer. All components are factory mounting points to simplify installation. The removable wired to convenient screw-type terminal strips
drain fitting is installed into the bottom of the drain pan for easy field connection and it can be quickly replaced ELECTRIC DEFROST without changing out the entire drain pan. End panels Electric Defrost models (KL*E) are designed for use can be slid out from the front of the unit providing easy in coolers and freezers between 34°F to -20°F. Defrost serviceability from the front or side of the unit, allowing heaters are mounted on the air intake side of the unit convenient access to the roomy electrical and piping for optimal performance and easy maintenance. A compartments. lower heater is installed inside the drain pan for fast, reliable drainage. A defrost termination fan delay COIL thermostat (DTFD) terminates the defrost cycle when the Copper hairpins consist of high efficiency 3/8” enhanced temperature is satisfied. The fan delay allows the warm copper tubes which are staggered and mechanically coil to cool after a defrost cycle prior to the fans turning expanded into corrugated aluminum fins achieving on. A heater safety thermostat is installed to prevent maximum heat transfer while reducing refrigerant overheating
charge. Die formed fin collars provide even fin spacing
Models are available in 4 and 6 fins per inch. Sweat HOT GAS DEFROST connections are standard on all models. There are two types of Hot Gas Defrost models available: 3-pipe Hot Gas models (KL*H) and 2-pipe Hot Gas MOTORS Reverse Cycle units (KL*G) (see pages 10 through 11 for Standard models feature highly efficient Electronically more details). Hot Gas Defrost models are designed for Commutated (EC) motors that can be field or factory use in coolers and freezers between 34°F and -20°F. All wired for dual speed operation. Dual Speed EC motors Hot Gas units include a fixed DTFD factory wired and an are available for 115V or 208/230V and are compliant electric drain pan heater
with California Title 24 regulations. PSC motors are also available for 115V, 208/230V or 460V requirements. All Optional Features motors include thermal overload protection

The kits are available asa factory installed option when ordered with a condensing unit. Not all Ed-Kits are available for all condensing unitmodels. The contents of each kit is described below, along with the function of each component
Timer: Initiates the defrost cycle. Also used as a override protection for defrost termination
Auxiliary Switch: It’s mounted on the compressor contactor and prevents the defrost contactor from operating whenever the compressor is energized
Block-Out Relay: Serves the same function as auxiliary switch. Used when defrost contactor is not required (lower wattage single phase only)
Defrost Contactor: Carries amperage load for heaters
Fan Contactor: Used with 460V motors or when 230V motors are wired 3 phase
Sequencing Relays: Provides interconnection of multiple unit coolers on a single system so that each unit cooler is allowed to individually terminate defrost on temperature

Frequently Asked Questions
Why choose a low profile unit cooler?
Heatcraft Low Profile Unit Coolers have been engineered for efficiency and improved air circulation. Features such as hinged and removable access panels, a hinged drain pan and an easy service motor mount reduce maintenance time and cost. Hinged, removable panels allows for easy access to components.
What is the best low profile cpu cooler for ultra slim computers?
Cryorig C7 is another low-profile cooler that should fit in any ultra slim computer chassis. It is taller than the SilverStone alternative at a height of 47 mm, but still quite short considering Intel’s stock cooler is around 60 mm. With a price tag of $30 and a six-year warranty, the Cryorig C7 is another great value low-profile cooler.
What is the thinnest air cooler available?
This low-profile cooler is just 34 mm tall, making it one of the thinnest air coolers available. Naturally, with such a tiny heatsink, it won’t be able to deliver impressive thermal performance. In fact, if possible, we recommend going with a slightly bigger cooler.
What are the benefits of a big cooler?
Those coolers tend to feature comparatively massive heatsinks, coupled with larger radiators and fans amongst other vital components for optimal airflow and enhanced heat dissipation to give you slight-to-extreme overclocking headspace.
