MicroTec Atlas Ultra AT48-APS Large Format Pneumatic Sublimation Heat Press — Double Station 40 x 48 in

The Atlas Ultra AT48-APS is a large format fully automatic double station pneumatic heat press designed for high-output sublimation and heat transfer production. It has a 39.4 x 47.2 in upper platen, dual pneumatic air cylinders, and an automatic reciprocating dual shuttle tray system that enables output of up to 175 units per hour. It runs on 240V 3-phase power at 30A and requires 38 CFM of compressed air supply. Temperature range is 50–437°F with digital time and temperature controls and both automatic and manual operation modes.

The Atlas Ultra AT48-APS has a 39.4 x 47.2 in upper heating platen. This covers the full print area of an adult XXL all-over sublimation garment in a single press cycle — no repositioning or multiple press passes needed. The same platen handles ChromaLuxe aluminum panels, ceramic tiles, wood panels, flags, and oversized promotional products in one press. The platen dimensions correspond to the industry-standard 40 x 48 in format used by most large-format sublimation paper and transfer media.

The AT48-APS has two independent shuttle trays beneath a single upper heating platen on an automatic reciprocating system. When a press cycle completes, the upper platen lifts and the machine automatically advances the second loaded tray into press position — no manual tray movement required. While the press cycle runs on one tray (typically 45–90 seconds for sublimation), the operator loads the next piece on the second tray. This parallel workflow eliminates idle time between cycles, keeping the heating element in near-continuous use and enabling output rates of up to 175 units per hour with a single operator.

The Atlas Ultra AT48-APS requires dedicated 240V 3-phase electrical service at 30A. This is an industrial power requirement — standard commercial 240V single-phase power is not compatible. Confirm your facility has 3-phase service available before ordering. A licensed electrician should install a dedicated circuit before the machine arrives. The machine draws 9,000W at full load. Do not attempt to connect the AT48-APS to a single-phase service or use a phase converter without confirming compatibility with the manufacturer.

The AT48-APS requires a compressed air supply capable of delivering 38.0 CFM at the machine’s operating pressure. This is a high CFM demand — most small and medium shop compressors (typically 5–15 CFM) are not sufficient for this machine. An industrial-grade compressor rated for at least 40 CFM continuous output at the required PSI is needed. Confirm your existing compressor specifications before purchasing. The compressor is not included with the machine. For production environments running the AT48-APS continuously, a dedicated compressor sized specifically for this CFM requirement is recommended to prevent pressure drops during long press cycles.

On a platen as large as 39.4 x 47.2 in, a single air cylinder press applies uneven force — higher pressure at the center of the platen and lower pressure toward the corners and edges. Uneven pressure on large-format sublimation produces inconsistent dye transfer — lighter zones at the platen edges and corners compared to the center, visible as color variation across the finished print. The AT48-APS uses two synchronized pneumatic cylinders — one on each side of the upper platen — to distribute press force evenly across the full platen surface. This edge-to-edge pressure consistency is critical for production-quality results on large pieces.

The Atlas Ultra AT48-APS is rated for up to 175 units per hour under standard production conditions. Actual output depends on the press time required for each substrate — standard polyester apparel sublimation typically runs at 45–60 seconds per cycle, while harder substrates like ceramic tiles or ChromaLuxe panels may require 60–90 seconds. The dual station automatic shuttle system maximizes output by eliminating idle time between press cycles — the operator loads during the press cycle rather than waiting for the platen to lift before loading.

The AT48-APS handles all major sublimation and heat transfer substrates including: all-over polyester apparel (jerseys, hoodies, sportswear, and adult XXL garments in a single press); ChromaLuxe aluminum photo panels up to 39.4 x 47.2 in; ceramic tiles and decorative panels; wood panels and photo slates; polyester flags and soft signage; and oversized promotional products including table covers, large mouse pads, and custom textile pieces. Temperature range of 50–437°F covers the full spectrum from delicate fabric sublimation to rigid hard-substrate transfer.

The Atlas Ultra AT48-APS measures 60.5 x 55 x 107 in (machine dimensions). It weighs 1,961 lbs net. Shipping dimensions are 76 x 73.6 x 73.8 in at 2,643 lbs. Delivery requires a freight carrier with liftgate service or a loading dock at the destination. Confirm door clearances, floor load capacity, and access route dimensions at the installation site before ordering. The machine footprint of 60.5 x 55 in requires adequate clearance on all sides for the shuttle tray extension and operator access.
