Holland Green Science Piesi 7 7 Ton Rosin Press

The 2.4 x 4.7 inch (6 x 12 cm) heating plates provide 11.28 square inches of pressing surface. This accommodates small to medium batch sizes, typically 1-7 grams of material depending on density and desired rosin thickness, making it ideal for personal use and small-scale extraction.

Temperature ranges vary by material type: lower temperatures (160-180°F) for fresh material, medium temperatures (180-220°F) for cured material, and higher temperatures (220-250°F) for older material. The 7-ton pressure capacity should be applied gradually while monitoring the pressure gauge to prevent blowouts.

The manual hydraulic bottle jack allows precise pressure application up to 7 tons. The included pressure gauge provides visual feedback to maintain consistent pressure levels throughout the extraction process, preventing under-pressing or material blowouts from excessive force.

The unit operates on standard 110V 60Hz power with 600W consumption, compatible with household electrical outlets. Heat-up times vary by target temperature, but the digital controller ensures accurate temperature maintenance once reached, with a 999-second timer for precise extraction timing.

The compact dimensions of 340 x 200 x 290 mm (13.4" x 7.9" x 11.4") make it suitable for countertop use and easy storage. The design allows for home use without requiring dedicated workspace while maintaining the structural integrity needed for 7-ton pressing operations.

The Piesi 7 7 Ton Rosin Press includes UL and CE safety certifications, pressure gauge for blowout prevention, and digital temperature control to prevent overheating. The hydraulic system provides controlled pressure application, while the compact design ensures stable operation during use.

Holland Green Science provides a limited 1-year warranty covering manufacturing defects and component failures under normal operation. The warranty does not cover operator error, abuse, or damage from improper use. Regular maintenance and proper operation are essential to maintain warranty coverage.
