Winco EMW-1800AT Spectrum 1800W Stackable Commercial Microwave

by Winco

Winco EMW-1800AT Spectrum 1800-Watt Stackable Commercial Microwave Oven (Touch Controls, 208/230V, NEMA 6-20P, ETL-Sanitation)

The Winco EMW-1800AT is an 1800-watt Spectrum heavy-duty commercial microwave with touch controls and a stackable chassis designed to be paired with another EMW-1800AT or with the EMW-2100BT for two-tier high-throughput service. The 22-5/8 inch wide by 20-3/4 inch deep by 14-1/2 inch high footprint is designed to occupy a compact counter or shelf position while still delivering heavy-duty wattage.

The EMW-1800AT runs on a 208/230V single-phase 20-amp circuit with a NEMA 6-20P plug and draws 18 amps. At 1800 watts of output, it re-thermalizes a typical 10-ounce pre-chilled entree in 30 to 40 seconds and is intended for high-volume service workflows where the medium-duty 1000W tier cannot keep up with ticket pace.

The EMW-1800AT is cETLus listed and ETL-Sanitation certified.

Best Use Cases for the EMW-1800AT

  • Stadium, arena, and large-venue concession stands with stacked dual-unit service
  • Hotel banquet operations re-thermalizing large events with stackable units
  • Hospital and senior-living tray lines re-thermalizing 200+ trays per meal service
  • High-volume quick-service restaurants with stacked microwave configurations at peak
  • Convenience store hot-case operations at high-traffic locations
  • Catering operations needing two-tier re-thermalization at large events
  • Operations that have limited counter footprint but need two heavy-duty microwave positions
  • Sandwich, salad, and bowl concepts with stacked make-line and service-line workflows
  • Coffee shop flagships with stacked food prep configurations
  • Any 208/230V operation that wants heavy-duty output in a stackable chassis

Stackable Chassis Design

The EMW-1800AT chassis is designed to stack with another EMW-1800AT or with the EMW-2100BT (same 22-5/8 x 20-3/4 x 14-1/2 inch footprint). Stacking two units gives a single station two independent microwave positions on one counter footprint, which doubles effective throughput without doubling the floor space. Each stacked unit runs on its own 208/230V 20-amp circuit.

This is functionally different from the Sharp TwinTouch dual-control approach (one unit with two control panels). Stackable units give two completely independent cavities and heating systems, which means two cycles can run truly simultaneously, not just two operators sharing one cavity.

1800 Watts on 208/230V

At 1800 watts of output on a 208/230V single-phase circuit drawing 18 amps, the EMW-1800AT delivers heavy-duty cook times. The unit re-thermalizes a typical 10-ounce pre-chilled entree in 30 to 40 seconds and defrosts a half-pound portion in 55 to 75 seconds. The 6-20P plug ships with the unit.

Touch Control Operation

The touch control panel lets staff program preset cook times and start cycles with a single button press per menu item. This makes the EMW-1800AT well-suited to high-volume operations where every staff member runs the same programmed presets for consistency across shifts.

Construction and Sanitation

Stainless steel exterior. ETL-Sanitation certified to ANSI/NSF 4 requirements for commercial food-zone equipment. Side-hinged door. The unit is designed for daily heavy-duty commercial service and pairs with the EMW-2100BT in mixed-stack configurations where one position handles slower complex items and the other handles faster re-thermalization.

Comparison to EMW-2100BT (Spectrum 2100W Stackable)

Same chassis, same footprint, same stackable design, same 208/230V/18A NEMA 6-20P electrical, same touch controls, same certifications. EMW-2100BT outputs 2100W instead of 1800W for roughly 15 percent faster cook times. Both units stack with each other in mixed configurations. Choose EMW-1800AT for slightly lower energy draw at peak. Choose EMW-2100BT when maximum cook speed is the priority.

Comparison to EMW-1000ST (Spectrum 1000W 120V Touch)

EMW-1000ST is 1000W on 120V/12A NEMA 5-15P (standard 15-amp outlet). EMW-1800AT is 1800W on 208/230V/18A NEMA 6-20P (heavy-duty 20-amp outlet) and stackable. Choose EMW-1000ST for any 120V station. Step up to EMW-1800AT for heavy-duty wattage and stackability when 208/230V is available.

Comparison to Sharp R-25JTF (Heavy-Duty Single-Control 2100W)

Both are 208/230V heavy-duty units on a 20-amp circuit with NEMA 6-20P plug. Sharp R-25JTF is 2100W single-control with a 0.7 cu ft cavity and dual magnetron. EMW-1800AT is 1800W with touch controls in a stackable chassis. Choose EMW-1800AT when stackability matters. Choose R-25JTF for the dual-magnetron heating system at single-position installations.

Frequently Asked Questions

What is the EMW-1800AT used for?

High-volume heavy-duty service where stackability and compact footprint both matter: stadium and arena concessions, hotel banquet operations, hospital and senior-living tray lines, high-volume quick-service restaurants, and any 208/230V operation that wants two heavy-duty microwave positions on one counter footprint.

What does stackable mean?

The EMW-1800AT chassis is designed to stack with another EMW-1800AT or with the EMW-2100BT (same footprint). Stacking gives two independent microwave positions on one counter footprint, with each unit running on its own 208/230V 20-amp circuit.

How is stackable different from Sharp TwinTouch?

Stackable units are two completely independent cavities and heating systems, so two cycles can run truly simultaneously. Sharp TwinTouch is one unit with two control panels sharing one cavity, where only one cycle runs at a time even though two operators have independent access to controls.

What is the difference between EMW-1800AT and EMW-2100BT?

Same chassis, same footprint, same stackable design, same electrical (208/230V/18A NEMA 6-20P). EMW-1800AT is 1800W. EMW-2100BT is 2100W for roughly 15 percent faster cook times. Both stack with each other in mixed configurations.

What electrical hookup does it need?

Dedicated 208/230V single-phase 20 amp circuit with NEMA 6-20R outlet. Draws 18 amps. Stacked configurations need one dedicated 20-amp 208/230V circuit per stacked position.

Can I stack on day one and add a second unit later?

Yes. Install the first unit on its own dedicated 208/230V 20-amp circuit and add a second unit (EMW-1800AT or EMW-2100BT) on a separate dedicated 208/230V 20-amp circuit when you are ready to expand. Run the second circuit during initial electrical work so the panel is sized for the future second position.

Is it NSF and UL listed?

Yes, cETLus listed for safety in the United States and Canada and ETL-Sanitation certified to ANSI/NSF 4 requirements.
