Radial Unit Coolers

Product catalog summary

Overview: The document introduces the new Thermokey THT-TBT series of unit coolers equipped with radial fans, designed for the refrigeration industry. These coolers are particularly suitable for large cold rooms and warehouses where efficient air distribution is required.

Specifications: The unit coolers are designed to operate with an external pressure of 150 Pa, which facilitates effective air distribution through textile, plastic, or other material ducts. The use of radial fans, as opposed to traditional centrifugal fans, allows for high external pressures and reduced sound levels, which is beneficial in environments where personnel are present for extended periods.

Design and Features: The radial fans are integrated into the air cooler using a complete fan and casing assembly. This design allows for various air discharge options, including frontal, top, bottom, and side discharges, which are not possible with centrifugal fans. The choice of radial fan depends on the cooling capacity, static pressure requirements, and desired sound pressure levels.

Models and Capacities: The document lists several models (e.g., THT 156.44, THT 256.46) with varying capacities, airflows, and other specifications. The selection of a model is based on required capacity and temperature difference, with examples provided for calculation.

Sound and Noise Levels: Sound pressure levels are measured at a 10m distance in a free field with a fitted air sock, according to EN 13487 standards. This ensures compliance with noise regulations in environments where noise levels are critical.

Defrosting and Additional Features: The units are supplied without a defrosting system, but a post-heating coil can be added upon request. This flexibility allows customization based on specific operational needs.

Technical Drawings: The document includes technical drawings and dimensions for various models, providing detailed information for installation and integration into existing systems.
