About PY Stark
Py Stark is a company specializing in energy and refrigeration solutions for the transport of refrigerated cargo. We work with equipment that ensures temperature control and the continuity of the cold chain in refrigerated trucks and containers.
Our systems, such as gensets, keep refrigeration equipment running even when there is no electrical connection, ensuring that food and sensitive products remain protected throughout transport.
We currently work with well-known brands such as Carrier Transicold and are looking to expand our portfolio to offer increasingly efficient and reliable solutions for refrigerated logistics.


Product
PY STARK works with leading global brands in transportation energy and refrigeration, offering reliable and efficient solutions for refrigerated freight logistics.
In the field of power generation, it utilizes technology from GENSET Motors, which develops compact, self-contained diesel generator sets (gensets), ensuring a continuous power supply for reefer containers even when electricity is not available.
In the refrigeration sector, it works with Carrier Transicold, a global leader with more than 50 years of experience, recognized for its efficient, durable, and environmentally friendly systems.
With this combination, PY STARK offers safety, temperature control, and high performance, ensuring that the cargo remains in good condition throughout the entire transport process.


Model UG 15P
The UG 15P suspended generator set was developed to provide continuous, stable, and reliable power to refrigerated containers (reefers), ensuring the proper preservation of sensitive cargo such as food, medicine, and perishable goods during transport.
It has a rated power of 15 kW (18.75 kVA) and is equipped with a Yanmar 4-cylinder diesel engine, which offers high performance with low fuel consumption (1.5 to 2.8 liters per hour), providing greater autonomy and reducing operating costs. It operates at 60 Hz, 460 V, in a three-phase system, with an automatic voltage regulator, ensuring stable power and protection for connected equipment.
Its structure is robust, compact, and corrosion-resistant, designed to withstand demanding transportation and logistics conditions. It also features a 180-liter tank, allowing for long workdays without the need for frequent refueling.
It is a reliable, efficient, and durable solution, ideal for ensuring a constant power supply in mobile cooling applications.


X4™ 7500 Trailer Refrigeration Unit
A high-capacity, high-performance refrigeration system designed for transporting temperature-sensitive cargo and for intensive operations. It offers rapid cooling, precise temperature control, and high energy efficiency, reducing fuel consumption and operating costs.
It incorporates EcoFORWARD™ technologies, which improve performance and meet emissions standards, as well as the APX™ intelligent control system, which ensures more precise thermal management and simple operation.
Its optimized design reduces motor load, minimizes maintenance, increases reliability, and lowers the total cost of ownership. It also uses R-452A refrigerant, which is more sustainable and has a lower environmental impact, and features an airflow of 3,050 cfm (5,180 m³/h) for even cooling distribution inside the compartment.
