Vacuum Drying Ovens, VDL Series, BINDER
Vacuum ovens are ideal for drying of all thermolabile substances, powders, and pastes, as well as for materials that contain solvents.

The VDL series ovens dry potentially explosive substances containing solvents. The pressure-encapsulated instrument box, preheating chamber, and associated heating elements use compressed air to prevent solvent vapors from entering the electrical zone. In the case of a pressure reduction in the instrument box, the unit undergoes an all-polarity-disconnect to safely avoid ignition sources. An additional flame protection gasket reliably extinguishes explosion flames preventing spreading to the area outside the unit. VDL series ovens can also be enhanced with optional explosion-proof chemical-membrane pump and differential pressure switch for controlling oven pressure. These ovens feature the patented APT.Line* preheating chamber technology, engineered to ensure all temperature-related tasks such as heating, drying, and sterilizing are conducted exactly the same each time, reliably and quickly.

The inner chamber is made of electro polished Type 316 stainless steel with rounded edges and internally welded seams for easy cleaning. The interior is completely tempered preventing condensation and ensuring moisture deposits will not impair drying results. This preheating chamber allows all connecting tubes to the inner chamber to be subjected to the heating process reducing the risk of condensation in the inner chamber. High-quality insulation reduces heat dissipation, which contributes to an active reduction in ambient temperature and avoids the need for additional air conditioning in the lab. Ovens feature pressure-resistant construction and a spring-mounted VDE-tested safety glass panel with splinter protection from explosion or implosion.

The aluminum shelves offer excellent thermal connection to the chamber walls, providing defined and reproducible temperature conditions for all samples, and safe direct temperature transfer without electrical ignition sources in the inner chamber. The removable rack holders, vacuum connections, and valves are made of Type 316 stainless steel. The two-point door lock and high-quality silicone gasket ensure tight closure of the chamber door. The low temperature of 50°C maximum of the external housing (even at working temperatures of 250°C) provides burn protection. The microprocessor controller with LED display and LCD screen allows easy programming of individual temperature profiles and advanced applications for reproducible drying processes. Calibration can be performed using the logical function keys. All ovens feature an RS-232 port, inert gas connection with fine-dosing aeration valve, analog manometer, and integral measuring gauge. The integral thermostat is rated Class 2, according to DIN 12880, Part 1. The inert gas connection features cross-flow technology, which guarantees complete flushing through the inner chamber, and provides even drying and shorter drying times.

Certifications: ATEX 95 compliant. The 115V models are UL listed. The 230V models are CE marked.
