Product Description
The Faithful WHL-25A Desktop Constant-Temperature Drying Oven provides efficient sample drying, baking, component heat treatment, and glass sterilization for research laboratories, industrial facilities, and agricultural testing centers across Bangladesh. This compact benchtop oven uses natural air convection to circulate hot air naturally across the chamber, protecting delicate powders and light samples from violent air currents.
The inner chamber features high-strength galvanized steel sheet construction, while the outer body uses cold-rolled steel with a corrosion-resistant electrostatic spray coating. High-density, CE-certified rock wool insulation fills the double-wall cabinet, preventing heat loss and maintaining safe outer casing temperatures. A top-mounted 35 mm exhaust hole vents moisture and off-gases efficiently while giving technicians an access port for external temperature monitoring probes.
A microcomputer intelligent PID controller drives the heating system, maintaining precise thermal stability within +/- 1.0°C. The controller displays real-time and target temperatures simultaneously on a dual-line LED screen. The system includes a Nickel-Chromium alloy heating wire, a PT100 temperature sensor, a 0 to 9999-minute process timer, and an over-temperature sound-and-light alarm to protect valuable laboratory samples from thermal damage.

Q2: What is the price of a desktop constant-temperature drying oven in Bangladesh (BD)?
Answer: Desktop laboratory drying ovens in Bangladesh generally range from BDT 20,000 to BDT 3,00,000+, depending on chamber capacity, air circulation system (natural convection vs. forced air), temperature range, and controller features. Compact desktop units like the Faithful WHL-25A (18L capacity) typically range between BDT 30,000 and BDT 50,000 as a complete set. For official price quotes, stock availability, and institutional procurement in BD, please contact Federal Scientific Mart (fsm.com.bd).
Q3: What heating mechanism does the WHL-25A oven use, and what are its benefits?
Answer: The WHL-25A utilizes Natural Convection heating. Hot air rises and circulates naturally inside the workroom without requiring high-velocity internal fans. This natural airflow prevents fine powders, delicate granules, and lightweight substrates from blowing around or cross-contaminating during the drying process.
Q4: What intelligent functions are built into the WHL-25A temperature controller?
Answer: The microcomputer PID controller features:
Dual Display: Upper LED row displays measured temperature; lower LED row displays set temperature.
Timer Functions: Programmable timer (0 to 9999 minutes) with fixed-temperature operation and auto-stop.
Advanced Features: Sensor deviation correction, temperature overshoot self-tuning, internal parameter locking, power-off parameter memory, and PT100 sensor accuracy.
Q5: What are the primary applications for the Faithful WHL-25A?
Answer: The WHL-25A is designed for drying, baking, heat treating, and conditioning in diverse environments:
Laboratory Glassware Drying: Rapid and safe drying of beakers, flasks, and glass tools.
Moisture Testing & Analysis: Dehydrating soil, food, agricultural grains, and textile samples.
Component Curing: Gentle thermal baking and heat processing of electronics, medical devices, and chemical compounds.
Educational & Research QA/QC: General constant-temperature heating in university and industrial QA laboratories.
Q6: How do you operate and set up the Faithful WHL-25A drying oven safely?
Answer:
Position the oven on a stable, heat-resistant bench top with adequate ventilation around the top 35 mm exhaust port.
Plug into a grounded AC 220V power socket.
Load samples evenly onto the 2 wire shelves, keeping space between items so natural air convection is not obstructed.
Set target temperature and timer on the touch-button PID panel.
The digital controller automatically regulates heating wire output and triggers a sound-light alarm if temperature overshoot occurs.
Q7: What is the difference between the WHL-25A and WHL-25AB models?
Answer: Both models share identical 18L chamber dimensions, 0.6 kW heating power, and PID control performance. The key difference lies in the inner chamber material:
WHL-25A: Inner chamber constructed from high-strength galvanized steel sheet.
WHL-25AB: Inner chamber constructed from corrosion-resistant mirror stainless steel.
Q8: Why purchase Faithful laboratory equipment from Federal Scientific Mart (fsm.com.bd)?
Answer: Purchasing through Federal Scientific Mart guarantees:
