Heat sealer designed for cleanroom use

PackworldUSA, the manufacturer of precision heat sealing equipment, highlights the PW4400 Series Heat Sealer, engineered for precision, versatility, and reliability in packaging applications.

The PW4400 Series is equipped with TOSS Touch Screen Control, providing real-time graphical displays of temperature, time, and pressure for consistent, high-quality seals. Operators benefit from intuitive menu navigation, easily programmable and lockable parameters, and menu-driven single-touch validation, streamlining both setup and critical process verification.

The PW4400 Series features Variable Resistance Control (VRC) technology for accurate, repeatable temperature control and fully programmable time, temperature, and pressure settings. Cooling cycles can be managed by time or temperature, giving users flexibility for a range of materials and applications. The exclusive AUTOCAL function simplifies calibration with automatic zero and multi-point calibration, ensuring temperature accuracy and regulatory compliance.

Designed for regulated environments, the PW4400 Series is fully validatable and calibratable, meeting ISO 11607 standards. Safety and process integrity are enhanced by alarm diagnostics, password protection, watchdog temperature monitoring, and an emergency stop button. Recipe storage allows for rapid product changeover, while a resettable seal counter and lot code supports efficient production tracking.

Available in tabletop 24-in and 36-in seal lengths, the PW4400 Series accommodates a wide variety of pouch and bag sizes. Its stainless steel case is easy to clean and ideal for sterile environments. The compressed air exhaust outlet maintains a cleanroom-ready operation and can be vented externally. Easy access to machine consumables ensures the shortest possible downtime for maintenance and replacement.

The PW4400 Series offers single or dual band operation, °C or °F display, and over 300 TOSS Alloy 20-C heatseal bands for customisable sealing. Optional features include vacuum/purge capability, an adjustable stand to vary sealer height and loading angle, stainless steel product table, and water-cooled jaws for specialized needs. The vacuum/purge system is highly versatile, offering gentle packing to reduce bulk without causing damage, a tight vacuum to prevent product movement, and multiple vacuum/purge cycles for maximum oxygen displacement. The final cycle is customizable for unique vacuum or purge parameters.

NIST traceable certification and CE compliance are available, supporting international quality standards. The PW4400 Series is backed by a 30-month warranty on all parts (excluding consumables) and lifetime support for long-term reliability.
