In professional kitchens where dishes cycle through quickly during service, hood-type (door-type) dishwashers remain one of the most practical investments. The large lift-up hood gives clear access to load and unload entire racks in seconds, while the short cycle times ensure that clean tableware is always available without long waiting periods. This simple yet effective design suits independent restaurants, hotel kitchens, banquet venues, staff canteens, cafés with high turnover, and catering companies alike.
Two Power Options – Same Machine Footprint
The Standard series is deliberately kept to two variants so kitchens can select the right electrical match without changing space planning:

GT-D1M (LE-RB) – single-phase model (220–240 V / 50–60 Hz)
Designed for locations with standard household/commercial single-phase supply or where lower connected load is preferred.
GT-D1M (TC-RB) – three-phase model (380–415 V / 50 Hz)
Built for kitchens that can utilize higher power for shorter cycles and stronger heating.

Both versions use the exact same external cabinet, simplifying specification, installation quotes, and future upgrades.
Practical Dimensions for Real-World Kitchens

Width × Depth × Height: 697 × 683 × 1620 mm
Useful loading height: 420 mm

At this size the machine fits comfortably in most dish-pit layouts or under standard-height workbenches, while the 420 mm loading level keeps repetitive lifting ergonomic and reduces operator fatigue across long shifts.
Cycle Flexibility to Match Service Pace
Operators can choose between two cycle lengths depending on soiling level and urgency:

Single-phase model: 70 seconds (standard) or 100 seconds (heavier soil)
Three-phase model: 60 seconds (fast) or 90 seconds (standard)

The three-phase version’s 60-second option is particularly valuable during peak lunch and dinner rushes when every minute counts.
Low Water Consumption & Efficient Heating
Both models are engineered for sensible resource use:

Rinse water per cycle: < 2.0 liters

Heating elements are matched to the power supply for reliable performance:
Single-phase GT-D1M LE-RB

Tank heater 2.0 kW
Booster heater 2.0 kW
Total load: 3.5 kW (15 A) or 5.5 kW (24 A)

Three-phase GT-D1M TC-RB

Tank heater 3.0 kW
Booster heater 9.0 kW
Total load: 11.0 kW (19.1 A) or 14.0 kW (25 A)

These specifications deliver the high rinse temperatures needed for effective sanitization while avoiding excessive energy draw.
Core Mechanical Components

Wash pump: 0.95 kW – provides vigorous water flow for thorough cleaning
Rinse pump: 0.25 kW – ensures accurate final rinse distribution

The interior is constructed entirely of stainless steel for durability, hygiene, and ease of maintenance. Simple electro-mechanical controls make daily use intuitive and keep service calls straightforward.
Typical Installations and Key Benefits
These dishwashers deliver the best return in mid-volume to high-volume settings that require:

fast rack processing (60–100 seconds)
dependable hot-water sanitizing
minimal training for staff
controlled utility costs
easy access to spare parts and technical support

Common applications include full-service restaurants, hotel F&B outlets, corporate dining rooms, educational and healthcare canteens, as well as off-site catering preparation kitchens.
