B4 VS PUR Low level sensor of adhesive (optional) Airtight cover with opening detection sensor Easy-to-use controls for temperatures Speed control using built-in pump control board Drain valve that makes maintenance easier For small and medium consumptions. Easy electronic control. Available for Pt100 or Ni120. Full motor control. Meler B4 VS PUR is a melting unit for low and medium consumption for reactive adhesives. The B4 VS PUR control has a built-in daily / weekly automatic start-up and stop timer. VARIABLE FLOW HOSE CONNECTION This device offers a wide range of manual and automatic flow adjustment options, by regulating the speed of the pump motor from 0 to 100 rpm. B4 has two connections for the hoseapplicator assembly. The hydraulic connections comply with the 9/16 18 UNF industrial standard. ELECTRONIC CONTROL HOLDING CAPACITY B4 controls temperatures with a high degree of accuracy, from 40 to 200 ºC (104 to 392 ºF). Its safety system controls the following: This unit is designed to melt small PUR blocks of up to 3 kg (6.6 lb). Once the device has been loaded, the adhesive is protected by an airtight cover and humidity-free gas injection system. Breakage of the temperature sensor and over excess temperature. Protects against application malfunctions. Communication with the main machine when the selected temperatures of all items have been reached. Thanks to its design, B4 VS PUR is easy to clean and maintain. g solutions partner Your gluing solutions partner Your gl
