Global-Tek Standard Series Door-Type Dishwashers: Everyday Reliability Meets Smart Efficiency Why Hood-Type Dishwashers Remain a Kitchen Favorite For many food-service businesses, the ideal dishwasher combines speed, simplicity, and a small footprint. Hood-type (also called door-type or pass-through) machines deliver exactly that: lift the hood, slide in a full 500×500 mm rack, lower the hood, press start — and in 60–100 seconds the dishes are clean, hot, and ready for the next service round. This minimal-touch workflow reduces handling time, lowers the risk of breakage, and keeps staff focused on front-of-house tasks rather than dishroom logistics. Single-Phase and Three-Phase Models Side by Side The Standard lineup consists of just two closely related models:
GT-D1M LE-RB — single-phase version (220–240 V, 50/60 Hz) Lower connected load, suitable for venues with standard power infrastructure or where energy tariffs favor single-phase supply. GT-D1M TC-RB — three-phase version (380–415 V, 50 Hz) Higher heating capacity and the shortest available cycle times for peak-hour performance.
Crucially, both models occupy the same external dimensions, allowing planners to finalise layouts before deciding on the final electrical specification. Ergonomic Size & Loading Height External measurements: 697 mm (W) × 683 mm (D) × 1620 mm (H) Rack entry height: 420 mm These proportions strike an effective balance — compact enough to fit most commercial dish areas, yet tall enough to provide generous internal clearance. The 420 mm loading height keeps repetitive rack movements comfortable and helps prevent common workplace strain over long shifts. Cycle Times That Adapt to the Rush Choose the cycle that matches the moment:
Single-phase model — 70 seconds (normal soil) or 100 seconds (heavier loads) Three-phase model — 60 seconds (express) or 90 seconds (standard)
The ability to drop to 60 seconds during busy periods can significantly increase the number of covers a kitchen can serve without running out of clean plates and glassware. Resource-Smart Design
Rinse water consumption: less than 2.0 L per cycle in both variants Stainless-steel construction throughout the wash chamber for longevity and easy cleaning
Heating is appropriately scaled: Single-phase GT-D1M LE-RB
Wash tank: 2.0 kW Booster: 2.0 kW Total: 3.5 kW / 15 A or 5.5 kW / 24 A
Three-phase GT-D1M TC-RB
Wash tank: 3.0 kW Booster: 9.0 kW Total: 11.0 kW / 19.1 A or 14.0 kW / 25 A
This setup achieves the high rinse temperatures required for proper sanitisation while keeping energy consumption reasonable for the performance delivered. Pumps and Controls Built for Daily Use
Wash pump — 0.95 kW (strong, consistent pressure across the rack) Rinse pump — 0.25 kW (accurate final rinse delivery)
Electro-mechanical controls are deliberately straightforward: fewer electronics to fail, easier diagnostics, and lower repair costs over the machine’s life. The robust stainless build further reduces the need for frequent interventions. Best-Fit Environments These dishwashers consistently perform well in:
mid-sized independent restaurants and bistros hotel coffee shops, room service pantries, and banqueting back-of-house corporate staff canteens and educational/institutional dining halls off-premise catering preparation kitchens busy cafés with high table-turnover
The single-phase model is especially popular in older buildings, retail food courts, and smaller independent operations, while the three-phase version unlocks peak efficiency in larger, busier venues. In Short contact Global-Tek offers proven, fuss-free performance: fast yet flexible cycles, very low water usage, ergonomic operation, durable stainless construction, and the smart choice between single- and three-phase power — all within one consistent cabinet size. It’s the kind of reliable daily workhorse that quietly helps professional kitchens maintain high hygiene standards and smooth service flow shift after shift.
