Thermal welder
SHR 500 is a manual operated sealing/cutting system composed by a sealing bar carrying a 12 mm wide resistance working on low tension (V24 max), and by a counter bar with a cold wire – diameter 0,9 (not electrically connected).
This type of seal avoids any contamination at the top of the bag, compared to regular impulse sealers.
A double timer allows to regulate separately both the sealing and the cooling time that allows the seal to consolidate before releasing the sealing jaws. The welder is supplied with a dedicated ergonomic trolley.
