CAN TUNNEL WARMER
Post-fill can warmer | tunnel warming system | condensation reduction for beverage packaging lines
Cold cans sweat the moment they hit ambient air. That condensation soaks cardboard trays, weakens packaging, and slows pack-out. The CODI Tunnel Warmer raises container temperature above the dew point by using hot water spray. Spray water recirculates through a closed loop with two temperature sensors holding the spray setpoint steady throughout the run. This is not a pasteurizer (although we build those too). Heating via instant hot water heaters or steam heat exchanger depending on your facility. CODI provides full throughput calculations for your line rate and temperature targets before you buy.
10 or 25 SqFt Treament Area
CIP capable
Reduce Condensation
Raises can temperature above the dew point after fill and seam, eliminating condensation before secondary packaging. Closed recirculation loop, instant hot water or steam heat exchanger. CMT-10 and CMT-25 models. Not a pasteurizer.
PRODUCT FEATURES
Closed Recirculation Loop
Spray water drains, recirculates, and a controlled side stream is reheated to hold spray temperature steady. Two sensors manage the loop continuously through the full run.
Variable Heating Configurations
Instant hot water heaters for facilities without steam. Heat exchanger with condensate recovery for facilities that have it. Codi specifies the heating units required for your line rate and temperature targets.
Sized to Your Line
CMT-10 at 2'x5', CMT-25 at 5'x5'. Codi provides full throughput calculations before you buy: entry temp, target exit temp, belt speed, spray temp, and BTU load.
Not a Pasteurizer
Operates well below pasteurization temperature. No PU calculations required. Temperature equalization only.
