Industrial refrigeration
Industrial facilities depend on controlled refrigeration when products, processes, or storage areas need defined temperature conditions. Uniref develops refrigeration systems around the actual process, from heat load calculation and equipment selection to installation, commissioning, and after sales support.
The refrigeration plant is not selected from facility size alone. Product temperature, incoming product conditions, room dimensions, daily movement, ambient conditions, humidity, door openings, power availability, and site utilities all influence the final system configuration.

Application engineering
Every industrial refrigeration project has different operating requirements. Uniref assesses the refrigeration duty, required temperature, heat load, product characteristics, site conditions, and available utilities before selecting the system configuration.
The engineering scope can include refrigeration equipment, cold rooms, controls, monitoring, electrical systems, installation, testing, and commissioning. The complete system is coordinated so that equipment selection remains aligned with the calculated refrigeration requirement.
Heat load calculation establishes the refrigeration duty by considering product load, ambient conditions, room dimensions, infiltration, equipment, lighting, and other sources of heat gain.
Temperature control is designed around the required operating range and the conditions specified for the stored product or industrial process.
Compressors, condensing units, evaporators, controls, and associated components are selected according to the calculated duty and operating conditions.
The refrigeration configuration is developed according to the application, required temperature, heat load, site utilities, and operating process.
Temperature controllers, sensors, alarms, data logging, and monitoring provisions can be integrated according to the facility's operational requirements.
The refrigeration equipment and associated systems are installed, tested, commissioned, and prepared for operation according to the project design.
