PDC’s (pdc-corp.com) new KRC 18-46-144 shrink tunnel was designed for food environments and includes features required to maintain high sanitary standards. The new shrink tunnel is used for shrinking tamper evident seals to secure the lids onto clear tubs and trays, such as those used for fresh fruits and vegetables.
The KRC 18-46-144 has an extra wide opening dimension of 14 inches to accommodate the widest trays and tubs of up to 12 inches in width. It also features a top electrical box housing the digital temperature controller, which is elevated by 3” to allow easy cleaning beneath it.
The tunnel controls are housed in upgraded NEMA-rated stainless steel electrical enclosures, which are UL approved. Electrical boxes are sloped so no food waste can rest on them. The base framework on the tunnel stand features square tubing angled at 45 degrees rather than flat. This also allows no food or waste to rest on it. Cleaning is simple and accessible.
The tunnel includes further upgrades to the blower fan controls providing variable speed controllers to fine tune airflow through the unit, minimizing turbulence in the tunnel chamber. The tunnel stand is a Power/Auto Lift system, allowing for motorized height adjustments, as well as automatically raising the tunnel in the event that the conveyor stops.
