Constant Temp. & Humidity Chamber, ICB-H-YH Series

Application

The constant temperature and humidity chamber is designed for long-term storage testing of pharmaceuticals, as well as quality assessment for the food, tobacco, and cosmetics industries. It is also widely used for aging and water absorption analysis of paints and resins, and environmental reliability testing for electronics, automotive components, and metallic materials.

Performance Advantages

• The frost-free design effectively avoids temperature and humidity drift caused by the absence of a defrosting function, or significant fluctuations in temperature and humidity during traditional defrosting cycles. It maintains excellent temperature and humidity stability even during long-term experiments.
• The circulating fan features three adjustable speed levels (high, medium, and low), providing a broader temperature and humidity testing range, as well as higher accuracy and stability, meeting users’ requirements for heating and cooling rates.
• The new diffusion-type air duct circulation system improves the uniformity of temperature and humidity.
• The water system is designed with automatic water replenishment and recycling, making it more water-saving and worry-free.
• The refrigeration system adopts hot gas bypass energy regulation technology to ensure efficient and safe operation of the compressor under high-temperature conditions.
• The programmable microcomputer fuzzy PID control technology, with 30 segments and 99 cycles, enables gradient and slope control of temperature rise and fall through the programmed settings of parameters such as temperature and humidity, circulating fan speed, running time, and heating rates.

Structural Features

• Wide-screen display: Convenient for setting programs and observing temperature, humidity, fan speed, running time, etc. It is equipped with temperature, humidity and water level alarm functions (visual indicators and audible prompts).
• Over-temperature protection system: Automatically interrupts operation when the preset temperature range is exceeded, featuring audible and visual alarms to ensure the safety of samples and the experimental environment.
• USB interface: Used to connect a printer or USB flash drive for real-time recording of temperature and humidity data during the experiment.
• Auxiliary lighting: Allows easy observation of the chamber interior in low-light environments; waterproof, resistant to high and low temperatures, and offers a long service life.
• Independent ventilation fan: Efficiently exhausts heat generated by the refrigeration compressor and electrical control components.
• φ40 test hole: Convenient for monitoring; equipped with a silicone soft plug to prevent air convection.
• German-style outer door handle: 90° rotating design with 4-point forced locking mechanism, ensures superior sealing, prevents air leakage, and enhances thermal insulation performance.
• Outer casing: Made of high-quality cold-rolled steel plate processed with powder coating technology, featuring uniform thickness and a sleek, beautiful
• Thickened insulation layer: Triple-layered high-density polyurethane insulating material, with thermal insulation performance meeting international standards for similar products.
• Tempered glass inner door: Allowsclear observation of the chamber without causing significant fluctuations in temperature and humidity; excellent explosion-proof properties ensure operator safety.
• Inner Chamber and Shelves: Precision-crafted from SUS304 stainless steel; the shelves are adjustable to the desired height.
• Square steel base: Constructed from integrally welded rectangular square steel for high strength and durability, ensuring stability without vibration.
• Universal casters: Can be freely turned and locked; made of wear-resistant polyurethane.
