Tetra Pak and Rheaco aseptic processing lines are the workhorses of citrus juicing, ESL dairy, and shelf-stable specialty product in Florida. The cooling side — chilled-water support to the cooling section, post-fill product cooling — needs refrigeration service that understands aseptic constraints.
Aseptic processing heats product to a sterilization temperature (typically 280–300°F for short residence), then cools through a regenerator and a chilled-water section before aseptic fill. The cooling-water loop is where refrigeration service intersects the line.
Tetra Pak and Rheaco both follow the same architecture; spare parts and service procedures differ.
The chiller producing aseptic-line cooling water is typically a 30–80-ton plant chiller running R-410A, R-454B, or for older units R-404A. Tampa Bay heat amplifies any capacity loss; plan for design-day operation at 95°F+ ambient.
Common service items: condenser cleaning, refrigerant charge verification, sensor calibration, VFD service on chiller pumps.
Refrigeration service inside the aseptic zone requires sanitation protocols and often coordination with the process control vendor. We do not break the sterility envelope without the customer's process control lead present.
Most cooling-side service happens outside the sterility zone — in the chiller plant and the cooling-water distribution loop.
Plant City, Polk County, and Lakeland host significant citrus juicing capacity. Tetra Pak and Rheaco lines run hard during October–February harvest season. Plan PM in the off-season; emergency response in season needs to be fast.
Coastal salt-air corrosion on Pinellas and west-Hillsborough plants accelerates condenser fin loss on rooftop chillers.
After aseptic fill, packaged product runs through a cooling tunnel or a holding cooler before palletization. This is the same cooling-tunnel diagnostic territory as any packaging line. See the cooling tunnel article for the refrigeration-side checklist.
Tunnel exit temperature affects shelf life and case-pack integrity. Set targets per product spec.
Aseptic lines are continuous-run. Service windows are short and scheduled. Plan major refrigeration work for documented sanitation breaks. Suncoast Cold Systems coordinates with line operations to minimize disruption.
Service-contract customers get scheduled-window response targets written into the agreement.
Cooling support: chiller plant, chilled-water loop, post-fill cooling tunnel. The aseptic processing equipment itself is serviced by the OEM (Tetra Pak, Rheaco) or specialty integrators.
Common configurations include 30–80-ton air-cooled chillers (Carrier, Trane, York) running R-410A or R-454B; older units on R-404A face AIM Act timing.
Outside October–February harvest peak. April–September is the planning window for major chiller work on citrus juice plants.
Yes for the food-safety side. Specific aseptic processing requirements also fall under 21 CFR 113 (for low-acid canned foods) where applicable.
We service the cooling-side supporting equipment around Tetra Pak lines. Tetra Pak's branded process equipment is OEM-serviced; we coordinate.
