**OAV-4 Oxalic Acid Vaporizer

Upgraded Design Compared to OAV-3**

Designed for Improved Colony Safety, Operational Safety, and Long-Term Reliability

1. Colony Safety & Heat Management

OAV-3: Conventional Copper Block Heating

The OAV-3 uses a large-surface copper block heating design. In practical application, this type of structure may present the following limitations:

• Heat disperses over a wide area during operation, which may allow elevated temperatures to enter the active bee space;

• Copper blocks can develop localized high-temperature zones when operating at full heat;

• Bees approaching or contacting overheated surfaces may experience stress or injury;

• Field use has shown a higher likelihood of bee disturbance due to uncontrolled heat exposure.

OAV-4: Directed Vapor Tube Design

The OAV-4 introduces a directed vapor outlet tube, providing a more controlled method of vapor delivery:

• Controlled heat direction

Oxalic acid vapor is generated internally and guided through a dedicated outlet tube, reducing uncontrolled heat dispersion inside the hive;

• Reduced contact with hot components

The defined vapor path minimizes the chance of bees contacting heated parts, supporting more stable colony activity during treatment.

2. Safety Features

• Overheat Protection

OAV-4 is equipped with an integrated overheat protection thermostat, designed to limit excessive temperatures during operation.

(OAV-3 does not include thermal protection.)

• Insulated Structure

Thermal insulation components help reduce the risk of accidental burns during handling and operation.

3. Ease of Use

• Manual Plug-In / Removable Lid Design

The OAV-4 features a simplified opening structure that allows easier loading, cleaning, and maintenance compared to earlier designs.

4. Performance & Efficiency

• Improved Oxalic Acid Utilization

The OAV-4 is engineered to achieve more consistent vaporization, improving effective use of oxalic acid compared to traditional open heating designs.

• Extended Component Life

Upgraded internal components are designed for longer service life, helping reduce maintenance and replacement costs over time.

5. Electrical System Optimization (OAV-4 Exclusive)

The OAV-4 incorporates a redesigned low-current control circuit to enhance durability and reliability:

• Overheat Protection Switch

• Operating current reduced from 16A to 50mA

• Significantly lowers electrical stress and extends switch lifespan

• Rocker Power Switch

• Operating current reduced from 16A to below 10mA

• Designed for improved longevity under repeated use

Product Positioning Summary

The OAV-4 Oxalic Acid Vaporizer represents a comprehensive upgrade over earlier designs, focusing on:

• More controlled heat and vapor delivery

• Enhanced operational safety

• Improved durability and component lifespan

• User-friendly handling and maintenance
