Key Specs

Overview Points

Semi-Automatic Assembly

Manual fin insertion with hydraulic expansion for fin-and-tube evaporators in refrigeration

Hydraulic Expansion

Presses aluminum tubes against fins with controlled force for consistent thermal contact

Alignment Guides

Integrated fin positioning guides reduce misalignment errors and minimize scrap rates

Compact Footprint

1200×1000×800mm dimensions fit existing workshops without structural modifications

Control Panel

Accessible buttons and display for direct expansion cycle oversight and setup control

Adjustable Fixtures

Accommodates different fin sizes and tube configurations for multiple evaporator models

Standard Power

380V/50Hz three-phase supply with custom voltage options for international installations

Stable Platform

500kg weight provides stability during hydraulic expansion for consistent joint quality

Key Features

Tight Fin-to-Tube Bonding

The hydraulic expansion system pushes tubes outward against fin collars with controlled, repeatable force, creating the close mechanical contact that directly determines heat transfer performance in the finished evaporator.

Manual Insertion with Guided Precision

Operators load and align fins using built-in guides before the hydraulic cycle engages, combining the flexibility of manual handling with the accuracy needed for uniform fin spacing across the full coil length.

Compact, Workshop-Ready Design

At 1200×1000×800mm and 500kg, the machine occupies minimal floor space while remaining heavy enough to stay stable under hydraulic load — no anchor bolts or reinforced foundations required for standard operation.

Flexible Production Capability

Adjustable alignment fixtures and interchangeable tooling allow the same machine to process different fin pitches, tube diameters, and evaporator lengths, reducing the need for dedicated equipment per product variant.

Simple, Reliable Controls

The external control cabinet houses clearly labeled push-button controls and a process display, enabling quick operator training and straightforward troubleshooting without specialized electrical knowledge.

Technical Specifications

The semi-automatic fin and tube expander is used for the production of refrigerator evaporator. The expansion tube is pushed by manual inserting and hydraulic pressure, so that the aluminum tube and the fin are closely connected, and the efficiency of the exchanger is better played.

Applications

Refrigerator and freezer evaporator assembly

Small-scale HVAC condenser and evaporator production

Commercial refrigeration coil manufacturing

Fin-and-tube heat exchanger fabrication for cooling systems

Aftermarket and replacement evaporator production
