Description

Programmable Thermostatic Drying Oven YR06444 -YR06445 is designed for drying, sterilization, thermal treatment, and storage in research laboratories, quality control, and industry. It features forced convection with adjustable airflow speed in 5 levels, microprocessor PID control, and an LCD touch screen with segment programming (RS485/232; in the “TC” version, a 4.3” touch screen with USB data storage), ensuring precise thermal stability and parameter traceability.

The ALLHEAT™ multilayer preheating system and ALLFLOW™ air cycle maintain a continuous and uniform temperature; the Pro-Insulation™ insulation reduces energy consumption and accelerates thermal recovery after door opening. Its SUS304 stainless steel chamber (40/70/130 L) offers uniformity ±1% (50–240 °C) and fluctuation ±0.5%, with resolution of 0.1 °C and a range from RT+5 °C to 300 °C. The design includes an integrated handle, double observation door to monitor without disrupting stability, and adjustable trays (max load of 20 kg per level; 40 kg total) improving ergonomics and safety. It includes an over-temperature alarm and supports 110/220 V – 50 Hz.

Frequently Asked Questions (FAQ):

• What’s the difference between models?
  The internal capacity (40/70/L), power (900/1100/W), and dimensions (chamber and external). The key control and programming functions remain the same across the series.
• Does it reach 300 °C?
  Yes, RT+5 °C to 300 °C, with heating up to 150 °C in ~30 min and excellent thermal recovery due to ALLHEAT™ + ALLFLOW™.
• Can it log data?
  It features RS485/232 and, in the “TC” version, a 4.3” touch screen with USB data storage.
• What maintenance does it require?
  Periodic cleaning of the SUS304 chamber, probe checks, door seal inspection, and annual calibration as per laboratory requirements.
• Does the observation door affect temperature?
  The double door allows monitoring without compromising stability, reducing heat loss.

Advantages and Disadvantages:

Advantages:

• Superior uniformity (±1%) with forced convection and ALLFLOW™ air cycle.
• PID control, segment programming, and password protection.
• SUS304 corrosion-resistant chamber and high-efficiency Pro-Insulation™.
• Traceability: RS485/232 and USB (TC version) for data management.
• Ergonomics: adjustable trays, integrated handle, and vertical design.

Possible Disadvantages:

• Advanced programming may require an initial learning curve.
• At temperatures near 300 °C, some consumables or materials require extra precautions.
• The fan noise (typical of forced convection) may be higher than in natural convection ovens.

Product Usage in the Field:

Ideal for microbiology (drying glassware and non-heat-sensitive materials), chemistry and pharmaceuticals (curing and pre-drying samples), industry (thermal treatment tests, stability, and accelerated aging), and quality control. Thermal uniformity and programmable control allow for temperature profiles (ramps/plateaus) to be set with repeatability between batches and recorded for audits. For daily operations, it is recommended to pre-load the oven, pre-stabilize the target temperature, and adjust airflow speed according to the sample mass and type to optimize times and uniformity.

Usage and Maintenance Recommendations:

• Plan segment programs for repetitive processes (e.g., ramp → plateau → controlled cooling).
• Distribute the load without obstructing airflow; do not exceed 20 kg per tray or 40 kg total.
• Record parameters via USB/RS485 to comply with GLP/ISO and facilitate audits.
• Inspect door seals, clean the SUS304 chamber with neutral products, and avoid abrasive agents.
• Perform annual calibration and check uniformity with reference thermocouples if required by protocol.
• In hot/humid environments (10–30 °C, <70% RH), ensure proper ventilation to maintain control stability.
