Low Temperature Cooling Chamber for DWTT Impact Specimens
1. User-Friendly Design: QualiLTC80™ DWTT features a split structure forming an "L" shape, with a high side housing the control panel for easy observation and operation, and a low side containing the freezing tank for convenient sample placement and securing. The height of the machine is aligned with the impact testing machine, allowing for quick and precise sample positioning.
2. Advanced Refrigeration System Components: QualiLTC80™ DWTT incorporates high-end components, including a fully enclosed compressor from France's Tecumseh, ensuring stable operation and a long service life. It features a high-efficiency external rotor condensing fan with low noise and durability, an imported brazed plate heat exchanger for compact and efficient cooling, and imported solenoid and expansion valves. The refrigerant used is environmentally friendly.
3. High Temperature Control Accuracy: QualiLTC80™ DWTT is equipped with a high-precision temperature control instrument with automatic PID adjustment to maintain a constant temperature. It includes a high-performance PT100 platinum resistance sensor with a stainless steel probe for stable and precise measurements. The fully enclosed stirring motor operates quietly and reliably in low-temperature, high-humidity environments. The tank medium is actively stirred for uniformity, and the high-quality stainless steel heater ensures safety and durability, minimizing temperature fluctuations.
4. Large Sample Capacity: QualiLTC80™ DWTT features two specimen baskets and can freeze up to 22 standard specimens of size (305±5) x (762±1.5) x (plate thickness 3~40) in one cycle. It also accommodates various NDT sample sizes:
- P-1: (360±1) x (90±2) x (25±2.5)
- P-2: (130±1) x (50±1) x (20±1)
- P-3: (130±1) x (50±1) x (16±0.5)
5. Convenient Operation: QualiLTC80™ DWTT is equipped with universal casters for easy mobility. Sample baskets make it simple to place and remove samples. A liquid discharge port allows for easy recycling of the cooling medium and cleaning. The system includes temperature alarms and insulation timing features to assist with efficient operation.
6. Comprehensive Protection Features: QualiLTC80™ DWTT includes various protection functions such as overload protection, leakage protection, phase loss protection, phase sequence protection, grounding protection, compressor overload protection, system pressure protection, medium over-temperature protection (anti-drying), and a unique expansion system.
