In laboratory and industrial settings where flammable volatiles are present, safety and precision are paramount. Thermoline's AS1681 Drying Ovens are meticulously engineered to meet these demands, providing a reliable solution for drying applications involving hazardous substances.
Compliance with AS1681-2002 Standards
The AS1681 Drying Ovens are designed in accordance with the Australian Standard AS1681-2002, which specifies safety requirements for electrically heated Type 1 ovens used in environments with flammable volatiles. This compliance ensures that the ovens are suitable for applications where explosion hazards exist due to the presence of volatile substances.
Key Features and Safety Mechanisms
-
Internal Purge Timer: Before heating commences, the oven initiates a pre-ventilation cycle, ensuring at least four complete air exchanges. This process effectively removes volatile vapours, minimising the risk of ignition.
-
Air Flow Sensor: The oven continuously monitors the pressure differential between the inlet and outlet ports. If the pressure falls below 5 pascals, indicating potential fan failure, or exceeds 45 pascals, suggesting a blockage, the system automatically shuts down to prevent hazardous conditions.
-
Explosion Vent Port: In the unlikely event of an internal explosion, the built-in vent port safely releases pressure, protecting both the equipment and the surrounding environment.
Robust Construction and Efficient Operation
Thermoline's AS1681 Drying Ovens are constructed with a stainless steel interior and a Colorbond exterior, fully insulated with high-grade fibreglass to ensure thermal efficiency. The ovens feature durable fan motors and heating elements, providing consistent performance over extended periods. Adjustable air inlet and exhaust vents facilitate optimal air circulation, enhancing drying efficiency.
Precise Temperature Control
Equipped with a PID digital controller, the ovens offer precise temperature regulation, ensuring consistent drying conditions. This level of control is crucial when working with sensitive materials that require exact temperature settings to prevent degradation or hazardous reactions.
Applications Across Various Industries
The AS1681 Drying Ovens are ideal for industries that handle flammable or volatile substances, including:
-
Chemical and Pharmaceutical Laboratories: Drying of solvents, reagents, and other volatile compounds.
-
Paint and Coatings Industry: Curing and drying of paints, varnishes, and similar materials.
-
Petrochemical Sector: Processing and drying of petroleum-based samples.
-
Research Institutions: Handling of experimental materials that emit volatile vapours during drying.
Available Models
Thermoline offers the AS1681 Drying Ovens in two capacities to accommodate varying operational needs:
-
TD-150F-AS1681: 150-litre capacity, suitable for smaller-scale
-
TD-500F-AS1681: 500-litre capacity, designed for larger-scale operations.
Both models maintain the same high standards of safety and performance, ensuring reliable operation regardless of scale.
Conclusion
Thermoline's AS1681 Drying Ovens represent a fusion of safety, precision, and durability, making them an indispensable asset in environments where handling volatile substances is routine. By adhering to stringent safety standards and incorporating advanced features, these ovens offer professionals across various industries peace of mind and operational efficiency.
