Finned Packs

Product catalog summary

Overview of Finned Pack Heat Exchangers

Fin Pack: Standard fin packs are made from aluminum fins, with options for copper, tinned copper, pre-painted aluminum, and stainless steel epoxy. These fins are designed with spacing rings for optimal spacing and contact with copper or stainless steel tubes.

Frame: The frame is primarily aluminum, with alternatives like FeZn, copper, stainless steel, and brass. It is designed to protect the finned pack and associated components.

Fins: The aluminum Tk fin design enhances efficiency and reduces pressure drop, featuring a central channel for better condensation drainage and increasing the heat exchange surface by up to 20%.

Tubes: Tubes are selected based on application needs and can be smooth or internally grooved copper or stainless steel.

Tests and Quality: Coils are pressure tested at 30 Bar in warm water after welding in an inert atmosphere. Production follows VISION 2000 (UNI EN ISO 9001:2000) standards, with each product certified for conformity.

Manufacturing Specifications: THERMOKEY specializes in medium to high capacity heat exchangers, with lengths up to 10 meters and fin pitches from 1.6 mm to 11 mm, using advanced programmable machines.

Geometry Specifications: Various geometries are available, with tube diameters from 5/16” to 5/8” and different configurations like equilateral triangular and square geometries.

Key Geometries: Detailed specifications for different geometries, including tube diameters, spacing, and configurations, are provided to meet diverse market demands.

Specifications: Tubes have a 5/8” external diameter, with specific spacing and arrangements for various applications, including heat pumps and refrigerant condensation.

Procedures: Safe handling of heat exchanger coil blocks involves using eyebolts and a threaded bar for lifting, ensuring stability during movement.

Standards and Limits: THERMOKEY coils operate within specific pressure and temperature limits for heating, cooling, condenser, and direct expansion coils.

Recommendations: Providing necessary technical data ensures prompt responses to inquiries. The TURBO FIN project enhances performance in dry conditions with an innovative louvered fin design.

Introduction The document highlights THERMOKEY's innovative heat exchanger designs, focusing on high-performance requirements in dry conditions.

Specifications and Design The new design features louvered fins creating a sinusoidal airflow path, enhancing turbulence and optimizing heat exchange.

Performance and Testing The TURBO FIN and grooved tubes combination maximizes thermal exchange while minimizing air pressure drop, confirmed by TÜV laboratory tests.

METOFIN® HVA Tubes These tubes have a unique 100-groove design, improving the heat exchange coefficient by 15% compared to standard grooved tubes.

Combination with TK Fin® Using METOFIN® HVA tubes with TK fin® corrugated fins significantly increases the global heat exchange coefficient, especially in refrigeration applications.

Advantages The combination reduces noise levels, energy consumption, and maintains high performance even at low air speeds.
