Metering Machine with PLC For PUR and Polyurea Foam

A new machine for spraying and pouring urethane foams and polyurea coatings is designed around PLC controls that minimize operator error.

A new machine for spraying and pouring urethane foams and polyurea coatings is designed around PLC controls that minimize operator error. The H-20/35 Pro-Tec from Graco Gusmer, Lakewood, N.J., boasts optimum control of material temperatures and displays real-time operating data and diagnostics. “If you want total control and increased productivity with more spray time, the H-20-35 Pro-Tec Series is tough to beat,” says director of sales and marketing Bill Hrynkiewicz. New patent-pending heaters (12 or 18 kw) reportedly provide rapid warm-up while maintaining stable operating temperatures at maximum flow rates. A new hose heater reportedly provides unequaled temperature stability in hose lengths 30% longer (up to 410 ft) than other currently available metering units. The Amploc control is said to ensure that voltage and amperage are automatically matched to hose length.
