Kramer 2 HP Medium Temperature Walk-In Cooler Refrigeration System
The Kramer KFO200E4SDA outdoor condensing unit and KL6A141ADASC low profile unit cooler form a factory-matched 2 HP medium temperature refrigeration package for walk-in coolers up to roughly 18 ft × 18 ft. A ZS15KAE scroll compressor drives a single three-fan KL6A141 coil, moving the line into full commercial-volume territory where a large sales-floor or back-of-house cooler runs hard all day. Configured for R448A or R449A refrigerant, it fits supermarkets, wholesale and distribution operations, large commissary kitchens, breweries, and beverage rooms.
Is a 2 HP Refrigeration System the Right Size?
This package is matched to medium temperature coolers up to about 18 ft × 18 ft holding 35°F to 38°F. At 25°F suction on R448A or R449A the KFO200E4SDA produces 16,840 BTUH at a 95°F ambient, and the matched system carries a rated capacity near 16,789 BTUH at 25°F SST, enough for roughly 320 square feet of well-insulated cooler at average usage.
Because floor plans vary, the system also covers long-and-narrow layouts that share a similar load, so a 12 ft × 22 ft galley cooler or an 8 ft × 32 ft reach-through runs on the same package as a square 18 ft × 18 ft room. It holds 14,790 BTUH at a 110°F ambient for hot rooftop and slab installations. High door traffic and warm product loaded in volume raise the load, so heavy-use rooms should size down one step; confirm against a calculated load.
Ideal for: supermarkets and grocery stores, wholesale and food distribution, large commissary and catering kitchens, craft breweries and taprooms, and beverage or dairy storage rooms.
Representative box sizes: this package is commonly applied to coolers such as 16 ft × 16 ft, 16 ft × 20 ft, 14 ft × 20 ft, and 18 ft × 18 ft, plus long-and-narrow layouts such as 12 ft × 22 ft, 10 ft × 28 ft, or 8 ft × 32 ft.

Recommended refrigeration applications are general guidelines only. Actual system requirements depend on insulation, ambient conditions, door openings, product load, and operating temperature. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

The KFO200E4SDA condensing unit and the KL6A141ADASC low profile evaporator are also stocked individually for replacement work. Ordering them together as this matched package keeps the condensing unit and coil capacities aligned at design conditions. All units ship under a nitrogen holding charge, so plan on field-supplied R-448A or R-449A refrigerant and evacuation, charging, and commissioning by an EPA 608 certified technician.

Frequently Asked Questions
What size cooler is the KFO200E4SDA sized for?
Medium-temperature coolers up to about 18 ft × 18 ft holding 35°F to 38°F, including long-and-narrow layouts of similar load. Confirm with a calculated heat load.
How is the KFO200E4SDA different from the 1.75 HP KFO180E4SDA?
It moves up to a ZS15KAE compressor producing about 16,840 BTUH at 95°F ambient and the three-fan KL6A141 coil, extending coverage to roughly 18 ft × 18 ft with stronger recovery in high-turnover rooms.
What line-set sizes does the KFO200E4SDA use?
The condensing unit and KL6A141 coil use a 3/8 in. liquid line and a 5/8 in. suction line. Final line sizing depends on the run length and lift between the units, which is set at installation.
What electrical service does the KFO200E4SDA require?
A dedicated 208-230V single-phase, 60 Hz circuit sized for about 14.1 rated load amps, with a 19.6 amp minimum circuit ampacity and 30 amp maximum overcurrent protection. The evaporator runs on 115V.
How high an outdoor ambient can it handle?
It is rated for outdoor installation and still delivers about 14,790 BTUH at a 110°F ambient, so it holds up on hot rooftops and unshaded slabs.
What operations is the KFO200E4SDA a good fit for?
Supermarkets, wholesale and food distribution, large commissary and catering kitchens, breweries, and beverage or dairy storage rooms.
