Sharp R21LTF Medium Duty Commercial Microwave Oven 1000W 1.0 Cu Ft 20 Memories 11 Power Levels Stainless Steel
Sharp R21LTF — 1000W Commercial Microwave with 20 Memories & 3-Stage Programming
The Sharp R21LTF (R-21LTF) is the most fully featured model in Sharp's medium duty commercial microwave line. It keeps everything the R21LVF offers and adds 20 programmable memories, 11 variable power levels, 3-stage programming that can defrost, cook and then finish at a different power, and Counter Check, which records how often each feature is used so managers can track operation. Two-Way Programming lets staff run Sharp's pre-programmed memories or set up to 20 of their own. Output is 1000 watts into a 1.0 cu. ft. stainless steel cavity, and the stainless cabinet, door and sturdy latch handle plug into a standard 120V outlet.
Key Features of the R21LTF
The R21LTF is built for operations that cook more than they reheat, where power level, staging and usage records matter as much as speed.
20 Memories, Two-Way Programming
Use the pre-programmed memories or manually program up to 20 of your own, with one-second increment timing and safeguards that block unauthorized changes.
11 Variable Power Levels
SelectaPower variable power gives 11 levels, so delicate items and sauces can heat gently while dense portions run at the full 1000 watts.
3-Stage Programming
Program food to defrost, then cook at one power level and finish at another, all in a single press, for consistent results on frozen menu items.
Counter Check
The oven remembers how often each feature was used plus the total number of manual uses, giving managers a closer view of how the unit is operated.
Express Defrost & Double Quantity
Express Defrost splits thawing into three stages at three power levels, and the Double Quantity pad automatically sets the right time for two portions.
Stainless Steel Inside and Out
The cabinet, 13-7/8" x 8-1/8" x 14-5/8" interior and door are stainless steel, and Memory Check lets staff confirm each pad's time and power before cooking.
Choosing between models: The R21LTF is the only R-21 model with variable power, 20 memories, 3-stage programming and Counter Check. The R21LVF offers 10 memories at 100% power, and the R21LCFS uses a simple 6-minute dial. All three share the same 20-1/2" cabinet and require 120V, 60 Hz power on a NEMA 5-15R receptacle at 14 amps.
Ideal Applications
Where a dial or single-power oven falls short, the R21LTF's staging and power control handle real cooking in a small footprint.
