Series H-20 Automatic Guns Automatic hot melt guns deliver high flow rates for multi-orifice applications and high viscosity materials. Nordson® Series H-20 Automatic Guns provide uniform bead deposition and offer increased flow capability for multi-orifice nozzles, high-viscosity hot melts and filled thermoplastic materials. The air-open/spring-close design provides speeds that exceed 3500 cycles per minute and ensures consistent performance and reliability. Series H-20-T Guns include resistance temperature detectors (RTDs) for precise temperature sensing and control of gun temperatures to within ±1ºF (0.5ºC) of setpoint. Design Flexibility The versatile Series H-20 is compatible with large diameter single or multi-orifice nozzles to meet a wide range of pattern variations. Several different gun configurations are available to satisfy specific application requirements. The standard H-20A version is used with non-circulating systems, as is the H-20 LBS design (large ball-and-seat) which features larger pathways. The micro-adjust H-20 provides direct flow control adjustment for applications requiring precise bead size. The H-20 Series is also available for circulating systems, as well as versions featuring water-resistant design, integral-filtered bodies to remove contaminants, nozzle extension assemblies and variable-temperature controls. Features and Benefits s Wide range of gun configurations satisfies numerous case sealing and product assembly application requirements. s Pattern versatility provided with choice of controlled-engagement single-orifice nozzles, precision multiorifice nozzles and extended nozzle assemblies. s RTD sensor ensures precise temperature control to within ±1˚F (0.5˚C) of setpoint. s High-flow capability provided in both standard and large ball-and-seat designs. s Optional filtered body version provides clog-free operation. s Optional engagement domed nozzles and high pressure capability (1500 psi/10.34 MPa) provide superior cut-off in case sealing and low-speed cartoning applications.
