Product catalog summary

Introduction
Thermokey presents the Blast Freezer Unit Coolers, designed for rapid freezing applications in various food industries such as meat, poultry, fish, bakery, dairy, ice cream, and ready-to-serve meals. These units are compatible with refrigerants R404A, R507, NH3, and CO2.

Specifications
The unit coolers are available in three series: FLT (R404A), FLA (NH3), and FLC (CO2), with capacities ranging from 14 to 107 kW at an evaporating temperature of -40°C and a temperature difference (ΔT1) of 5K. The units feature a lower refrigerant charge compared to market alternatives, offering environmental and budgetary benefits. Standard configurations include an aluminum casing painted RAL 9010, copper piping for FLT, stainless steel piping for FLA and FLC, 12 mm fin spacing, 630 mm fan diameter, and a 3-phase 400V 50/60 Hz motor fan.

Customization Options
Customizations include stainless steel or galvanized steel casing, special fans for high static pressure, various defrost systems (electric, hot gas, etc.), different fin spacing, and coil protection options.

Performance and Selection
The nominal capacities are based on specific conditions: ΔT1 = 5 K, incoming air temperature T1 = -35 °C, and evaporating temperature Te = -40 °C. The selection of the correct model can be made using the provided formula and factors for different ΔT1 values.

Technical Data
The document provides detailed technical data for each model, including capacity, air flow, surface area, fan-motor specifications, defrost systems, noise levels, connections, tube volume, and weights. The data is organized by series (FLT, FLA, FLC) and includes information on sound pressure and power levels according to EN 13487/EN ISO 3744 standards.

Conclusion
Thermokey's Blast Freezer Unit Coolers offer efficient and customizable solutions for rapid freezing needs in the food industry, with a focus on reducing environmental impact and operational costs.
