Thermo King built the S-610M on its Precedent S-Series platform and optimized it for food distribution: the host unit cools zone 1 and remote evaporators cool the others, for two or three zones in one trailer. It is CARB Evergreen certified, so it needs no DPF, and it uses R452A refrigerant.
Fresh and frozen, one trailer.
What Thermo King built into the S-610M for mixed loads: zones, emissions, and telematics.
Two or three zones.

Thermo King designs its multi-temp systems to control two or three compartments, and any compartment can be set at any temperature. On the S-610M, the host unit's evaporator controls zone 1 and a ceiling-mounted remote evaporator controls zone 2; a three-zone trailer adds remote evaporators for zone 3.
- Supports 1, 2, and 3 zone operation with up to four remote evaporators
- Numerous zone configurations within the trailer
- Zone 1 runs whenever the unit is on; zones 2 and 3 can be turned on and off as needed
Walls between the zones.
Insulated bulkheads separate a multi-temp trailer into zones, each with its own setpoint. Thermo King's PrimAir insulated bulkheads enable consistent temperature zones, and a multiple-compartment trailer should have a center bulkhead with tight air seals. To haul one temperature, move the dividing walls to make one compartment; with Single Zone Control enabled, every zone runs to the same setpoint.
No DPF, ever.
Thermo King developed the Precedent S-Series to achieve Evergreen CARB and EPA emissions compliance without a diesel particulate filter. The S-610M has held CARB Evergreen certification since 2013, complies with the highest possible EPA standards for engines over 25 HP (Tier IV), and is CARB ULETRU compliant.
- No need for a diesel particulate filter (DPF)
- CARB Evergreen certification since 2013
- EPA >25 HP Tier IV

Questions
About the S-610M. Anything else, call your shop.
How many temperature zones can the S-610M run?
Two or three. The host unit's evaporator controls zone 1 and a remote evaporator controls zone 2; a three-zone setup adds remote evaporators. Thermo King's multi-temp platform supports up to four remote evaporators.
What's the difference between the S-610M and the S-610DE?
The S-610M builds its extra zones with remote evaporators. The S-610DE runs two zones without remote evaporators, side by side down the length of the trailer. For California fleets, the S-610DE is the pick if you prefer dual lane loading, and the S-610M if you don't.
Can I run it in California?
Yes. The S-610M has held CARB Evergreen certification since 2013 and is CARB ULETRU compliant, with no DPF required.
Can it run on electric standby?
As an option. SmartPower electric standby comes in standard and high output (HO) versions, with 230-volt and 460-volt three-phase motors. On electric power the S-610M is rated at 44,000 BTU/hr at 35°F; ask your shop for the performance of a specific option.
What refrigerant does it use?
R452A, with a charge of about 17 lbs. It reduces the carbon footprint of refrigerants used by fleets by nearly 50%.
Is telematics included?
Yes. Every S-610M is factory equipped with 24 months of complimentary TracKing telematics.
How often does it need service?
The maintenance interval is 3,000 or 4,000 hours, and the 1,500-, 3,000-, and 4,500-hour/annual inspections should be performed by an authorized Thermo King dealer. TKSE is one, with factory-trained technicians at seven shops in Florida, Georgia, and Mississippi.
Can a multi-temp trailer haul a single-temperature load?
Yes. Reposition the dividing walls to make one large compartment; with Single Zone Control enabled, all zones run to the same setpoint.
