Industrial shrink tunnels - series HR-HOLITERM are set for foil shrink around packaged objects. These tunnels are equipped with EXTRA JET technology enabling more effective hot-air flow inside shrinking chamber. This technology reduces energy demand markedly at keeping shrink performance. These machines are equipped in standard version with continuous conveyor control with soft start, digital temperature control inside the shrinking chamber and cooling-air fans on the output of the tunnel. Optionally, the machine can be delivered with a cooling and automatic switch off program. Industrial shrink tunnels are intended especially for high frequency strapping jobs or for thicker foil shrinking.
