J&D JD3620 Heat Shrink Tunnel | 20" x 15" Opening | S/N 0403620TLDJD | 220V 3-Ph

1996 J&D JD3620 Industrial Heat Shrink Tunnel | S/N 0403620TLDJD 20" x 15" Opening | 36" High-Velocity Chamber | 220V 3-Phase

This J&D JD3620 is a robust, industrial-grade shrink tunnel designed for 24/7 production environments. Featuring a 36-inch recirculating heat chamber, this unit provides the necessary dwell time for consistent, wrinkle-free shrinking even at high conveyor speeds. This model is a favorite among maintenance teams due to its rugged steel construction and standard, easy-to-source electrical parts.

Equipped with a live roller rod conveyor and high-velocity blower system, the JD3620 handles everything from retail multi-packs to heavy industrial bundles. The variable speed control and digital temperature interface allow for precise tuning across various film types (PVC, POF, PE).

• Proven Reliability: 1996 build with a focus on mechanical durability and simple serviceability.
• High Throughput: The 36" tunnel length supports faster line speeds than standard 24" units.
• Uniform Heat Distribution: High-volume air recirculation prevents hot spots and ensures a professional finish.
• Industrial Mobility: Mounted on heavy-duty locking casters for easy integration into any packaging line.
• Heavyweight Stability: At 1,300 lbs, this machine is built to stay level and perform under heavy load.

The J&D JD3620 is designed to provide consistent heat for high-speed industrial shrink applications. While exact range specifications can vary slightly based on the year of manufacture and the specific digital controller installed, the standard operating range for this class of industrial tunnel is as follows:

• Standard Temperature Range: Room Temperature to 400°F (approx. 204°C).
• Optimal Operating Temperature: Most polyolefin (POF) films shrink best between 250°F and 325°F.
• Maximum Safety Limit: Typically capped at 400°F to prevent damage to the conveyor rollers and internal components.

Key Heating Features

• Digital Control: Features a solid-state digital temperature controller that allows you to set and lock the exact heat level to within +/- 5 degrees.
• Recirculating Airflow: A high-velocity blower motor ensures that air is continuously moved throughout the 36-inch chamber, preventing "dead spots" and ensuring an even shrink on all sides of the product.
• Cool Down Cycle: Includes an automatic "cool down" feature that keeps the blower running after the heaters are turned off to safely dissipate heat and protect the motor.
• Dwell Time Versatility: Because the tunnel is 36 inches long, you can often run at a lower temperature with a faster conveyor speed, or vice versa, to accommodate delicate products.
