YH-60B Standard Constant Temperature and Humidity Curing Cabinet
Application & Usage
This standard curing cabinet is specially designed for curing concrete cubes, cement mortar specimens and hydraulic binder samples, widely deployed in cement plants, construction test labs, third-party inspection institutions, highway & bridge engineering sites and building material research centers.
Core Application Scenarios
● Cure 150×150×150mm concrete strength test blocks for 28-day standard hydration test.
● Maintain cement mortar prisms for flexural & compressive strength testing.
● Standard curing of mortar, geopolymer and other cementitious specimens to meet global testing standards.
Standard Operation Steps
1. Fill clean water into the bottom water tank before startup;
2. Power on and set target temperature (20℃) and humidity (≥95%RH) via digital control panel;
3. Wait until internal environment stabilizes, then place specimens evenly on stainless steel racks;
4. Close double doors tightly, the machine runs fully automatic curing cycle without manual adjustment;
5. Check digital display in real time for temperature & humidity data throughout curing period.
Core Functional Features
- Global Standard Compliance: Fully meets GB/T 50081, JG3037, ISO and ASTM curing requirements, supports CE certification for overseas customs clearance.
- Precise Dual Env Control: Steady temperature range 20±2℃, relative humidity consistently above 95%; uniform internal air circulation eliminates local temperature difference.
- Large Loading Capacity: Inner dimension 960×570×1000mm, holds up to 60 sets of standard concrete cubes, ideal for medium-volume labs and construction projects.
- Fully Automatic Intelligent Operation: Integrated refrigeration, heating & ultrasonic humidification system; auto-switch cooling/heating/humidifying without human intervention.
- Digital Visual Control Panel: Real-time digital readout of temperature, humidity and working status; simple parameter calibration for operators.
- Energy-saving Stable Cycle: Hidden built-in compressor and layered airflow design, low power consumption and long continuous running life.
- Double Insulated Door Structure: Sealed anti-leakage double door reduces internal heat & moisture loss, guarantees stable internal environment.
Premium Material Configuration
1. Outer Cabinet: High-quality cold rolled steel with electrostatic spray coating, anti-rust, scratch-resistant and wear-proof for long-term workshop use.
2. Inner Tank & Storage Racks: Full stainless steel 304 material, anti-corrosion against water vapor and cement slurry, easy to rinse and clean.
3. Insulation Layer: Thick polyurethane foam sandwiched between inner & outer shells, excellent heat preservation to cut energy consumption.
4. Humidification Assembly: High-efficiency ultrasonic atomizer, stable mist output without water droplet dripping on samples.
5. Control System Components: Industrial digital temperature & humidity controller, waterproof operation panel with long service lifespan.
6. Sealing Strip: Silicone rubber door gasket, high airtightness to avoid humidity leakage.
Working Principle
The cabinet adopts closed-loop automatic temperature & humidity feedback control technology:
1. Built-in temperature & humidity sensors continuously collect real-time internal environmental data and transmit signals to the central digital controller.
2. Temperature Regulation Logic: When internal temperature is lower than 20℃, the heating system activates; when temperature exceeds 22℃, the refrigeration compressor automatically starts to cool down, maintaining 20±2℃ constant temperature.
3. Humidity Regulation Logic: The ultrasonic humidifier atomizes clean water into fine mist. Once internal humidity drops below 95%RH, the humidification system automatically boosts mist output to sustain high-humidity curing atmosphere.
4. Circulation fan evenly distributes temperature and mist across the whole inner chamber, ensuring every specimen receives identical curing conditions for accurate test results.
5. All systems operate automatically in cycles without manual supervision for long-duration curing tasks (3d, 7d, 28d).
FAQ
Q1: What International Standards Can This YH-60B Curing Cabinet Satisfy?
A: It complies with China GB/T 50081, JG3037, ISO 1920 and ASTM C192 standards. We can provide CE certification documents together with the machine for overseas laboratory and construction company customs clearance.
Q2: How Many Standard Concrete Cubes Can This Cabinet Hold At Maximum?
A: The internal space supports 60 groups of 150×150×150mm concrete test cubes (total 90 blocks). Multiple detachable stainless steel racks allow flexible adjustment for smaller cement mortar specimens.
Q3: Is Frequent Manual Adjustment Required During The Curing Process?
A: No manual adjustment is needed after initial parameter setup. The integrated refrigeration, heating and ultrasonic humidification system runs fully automatically, maintaining constant temperature and humidity 24/7 for the whole curing cycle.
Q4: What Maintenance Work Does This Curing Cabinet Require?
A: Daily maintenance only requires regular water refilling in the bottom tank; weekly cleaning of stainless steel inner tank and racks to remove residual cement slurry; monthly descaling for the ultrasonic humidifier to guarantee stable mist output. All spare consumable parts (atomizer, sealing strips) are supplied together with the machine.
Q5: Can This Machine Work Stably In High-Temperature Construction Site Environments?
A: Yes. The thick polyurethane insulation layer and high-power refrigeration compressor ensure stable 20±2℃ internal temperature even if ambient workshop temperature reaches up to 40℃. The waterproof control panel is designed to adapt to harsh construction lab environments.
