Thermo King introduced two new systems that support reliable load quality during extended transport.
The Heat King 430 series for rail, truck, and trailer and the Auto Fresh Air Exchange for SB-RR refrigeration units for rail were showcased at the Intermodal Association of North America (IANA) Expo in Atlanta GA recently.
Thermo King engineers created the Heat King 430 series to provide reliable freeze protection for temperature-sensitive cargo while increasing uptime, lowering life cycle costs, and increasing operator efficiency.
The Heat King 430 Series increases uptime through more reliable control components based on solid-state technology to avoid moving parts that can break. The footprint of the human-machine interface (HMI) has been reduced by more than 85% to minimize the chance of damage during container and trailer loading. Engineers placed the controller inside the unit enclosure for further protection.
This unit provides flash-load programming capability and features system diagnostics for easy troubleshooting and lower labor costs. It also retains error codes indefinitely rather than losing them when the unit is turned off.
Return and supply air temperature sensors provide built-in redundancy to ensure that, if one sensor fails, the other provides continued performance. An added tank enables a more robust cooling system for increased uptime. The unit features an impact-resistant battery hold-down.
A new controller algorithm automatically starts the unit when the coolant drops below 30° F for easier cold starting and increased battery life.
The Auto Fresh Air Exchange option for SB-RR refrigeration units ensures delivery of fresh air to unattended rail containers via remote access to maximize shelf life and improve food quality during extended transport. This feature can control the flow of fresh air and monitor the state of the mechanism either locally at the HMI or remotely via third-party telematics.
This system keeps loads safe from gas build-up inside the refrigerated space. A simplified design provides reliability and ease of use, which increases operator efficiency. This solution can be used on rail boxcar, container-on-flatcar, and trailer-on-flatcar applications.
The auto fresh air exchange keeps air flowing in the refrigerated cargo space. It prevents build-up when hauling cargo such as potatoes and onions that gives off excess amounts of carbon dioxide.
A feedback switch monitors the physical state of the mechanism, indicating to both the controller software and the user that the auto fresh air exchange is working properly.
