Thermo king reefer training course

Refrigerated transport enables large quantities of perishable goods to be moved and distributed from one place to another, even to distant markets, while preserving their composition and quality.

We have a training program that includes the most prestigious brands, and all types of systems present.

We have called our teaching modality “Learning by experience”, developed on the basis of online simulators.

  • In each module, we present the student with an online simulator of the system to study.
  • The simulator shows what function each component performs, in order for the student to understand how the entire system works.
  • The student can vary the working conditions of the system within the simulator, for example amount of refrigerated product, ambient temperature, engine revolutions per minute, etc.
  • By varying the working conditions, it is analyzed how a circuit responds with these changes. Faults, and symptoms can be analyzed under irregular working conditions.
  • The student becomes familiar with the systems, components, and possible faults.
  • The student acquires behavior experiences in each model, to apply them in real situations.
  • A teacher is assigned for student questions.
  • The student performs a task in each study module. Upon passing the assignment, the student advances to the next module.

Why enroll in Conforempresarial’s reefer trailer school

Because our program develops applied engineering in transport refrigeration systems. Therefore any model and brand will be included and developed here.

  • A technician in charge of the maintenance of refrigerated units must be a comprehensive professional in all areas.
  • In the transportation refrigeration area, it is common to change a damaged component or to perform a refrigerant recharge as corrective maintenance.
  • But predictive maintenance is more important, for example, finding a fault before it affects the customer’s product, when, for example, the truck has traveled miles and cannot be attended to quickly.
  • Responsiveness can be the difference between offering a good product or a broken product.

What is studied in our Transport Refrigeration courses?

Our refrigerated transport course studies in detail the equipment of the sector and its variants.

A single course that includes the operation of the systems of the main brands, in all its modalities:

  • Refrigerated trucking training
  • Reefer container training
  • Trailers refrigeration course

Training Classes in Equipment with a compressor directly coupled to the transport motor.

Generally used in medium and small trucks, most commonly used in product distribution for short distances, or small volumetric loads.

Online training in Equipments with independent compressor to the transport motor.

Transport refrigeration models for larger trucks include a system independent from the automotive engine, with its own diesel engine.

It can be in two pieces or one, that is:

  • With evaporator separated from the system.
  • With evaporator attached to the equipment as a single system.

By having a compressor independent of the automotive engine, the cooling capacity is totally independent of the transport speed.

Transportation refrigeration technician training in equipment capable of working with an electrical power source while transportation is stopped.

  • The refrigeration models for transport, with the possibility of diesel operation during the road, and electric with the car stopped, are ideal for product distribution over longer distances.
  • The purpose of these systems is to turn on the equipment in electric mode, with the transport stopped in places where noise or work from the diesel engine is inconvenient.

Transport refrigeration school for all-electric systems.

  • They have the advantage of not requiring modification to the engine part of the vehicle.
  • Although it is important to mention that fully electric units often need a higher power alternator to ensure the cooling system battery charge
  • These refrigeration equipment for totally electric transport have the advantage of being able to use the refrigeration system, when the car is off, using the battery for this purpose.
  • Due to the use of the totally electric transport refrigeration system, zero emissions are produced from the load cooling process, allowing the use of these models at any time and in any area, even exceeding environmental regulations.

Teaching of refrigeration units for trailers

  • The transport refrigeration systems for trailers are totally independent from the car engine.
  • The refrigeration systems for trailers, mostly have the possibility of working with power from the electrical network, when the car is at rest.
  • Refrigeration systems for trailers can have more than one evaporator, for several compartments, even at different temperatures.
  • Refrigeration system for trailer with compressor coupled to the unit’s diesel engine.
  • The refrigeration systems for trailers can have fans driven by bands, or with a fully electric fan system.
  • Refrigeration system for trailer with electric compressor, powered by the system’s three-phase generator.

Hybrid cooling systems, a comfortable exchange between diesel and electric operating modes.

  • Hybrid units for truck and trailer refrigeration automatically switch between electric and diesel operation as required or necessary.
  • This allows transport companies to operate in urban centers, residential areas and low emission areas with the diesel engine of the refrigeration unit switched off.
  • The driver only needs to set up the vehicle when leaving the depot and the system will seamlessly switch to electric and diesel modes during the workday, depending on the needs of the unit.

Transport Refrigeration Technician Training

Carrier and Thermoking equipment has the basic systems of a compression refrigeration equipment, that is: evaporator, compressor, condenser, expansion valve, plus variants in control systems to improve performance, or increase the useful life of the equipment.

Refrigeration equipment parts in carrier and thermo king transport


  • Produces the movement of the refrigerant within the system.
  • It generates the high pressure in the system, and the low pressure in the suction.
  • The type most used by thermo king and carrier is the piston compressor. The compressors can be powered by electricity, by bands or direct couplings to independent motors.
  • Due to freezing temperatures, systems need high compression ratios, where the piston compressor is most efficient.
  • They can have control systems, to adapt them to partial thermal loads.
  • Scroll-type compressors are also used, although the favorites are piston ones.
  • There are compressors always powered by electric motor, such as those used in the B-100 series for small vehicles, from the company Frascold specifically model C206
  • In the compressors coupled to the vehicle’s engine, such as those used in the thermo king V series for trucks, the TM series stands out.

Expansion valves:

  • In charge of delivering to the evaporator only the liquid refrigerant that the system needs.
  • The thermostatic expansion valve has a bulb to measure the superheat at the outlet of the evaporator.
  • Electronic-type expansion valves require a pressure sensor at the compressor suction, and a thermistor at the evaporator outlet, in order to maintain a low refrigerant superheat.


Thermo king uses various types of motors to drive the compressors that work independently of the vehicle’s engine. For example, the engine TK270, TK370, of the yanmar brand, used in the T series are used.


Large condensers with microchannel technology, to achieve the minimum pressures required for refrigerant condensation.


  • When the equipment works with a pressure switch, it is generally the same compressor.
  • When we refer to pressure sensors, they can be located in the system piping.
