Applications
High-Temperature Curing Chamber, also known as a drying and curing room, is an advanced hot air circulation system designed for curing large electrical components, motors, coatings, chemical products, and surfaces, as well as for drying moisture from food and various other products. It ensures uniform temperature distribution throughout the working chamber.
Standards
(1) GB 50052: Code for design of power supply and distribution systems.
(2) GB 50054: Code for design of low-voltage electrical installations.
(3) GB 50169: Code for construction and acceptance of grounding devices in electrical installations.
(4) GB 50243: Code for acceptance of construction quality of ventilation and air conditioning works.
(5) IEC 60068-2-2: Environmental testing - Part 2-2: Tests - Test B: Dry heat.
(6) ISO 9001: Quality management systems (Production compliance).
Features
1. Mechanical Structure: Primarily composed of an electrical control system, insulated chamber system, air circulation system, heating system, humidification and water circuit system, refrigeration and dehumidification system, etc.
2. Utilizes modular insulated chamber panels, allowing for arbitrary expansion of internal volume. Easy to assemble and disassemble, with dimensions customizable by the customer.
3. The interior features SUS#304 stainless steel panels, while the exterior utilizes Baosteel A3 powder-coated steel for an aesthetically pleasing finish. Insulation layers employ PU foam or rock wool.
4. The control system incorporates imported single-point or programmable controllers with a user-friendly interface, allowing flexible parameter settings for convenient operation.
5. Refrigeration units incorporate imported European/American compressors with eco-friendly refrigerants. A dual-circuit low-temperature system design employs separate compressors for different temperature zones, extending equipment lifespan.
6. Large observation windows in interior doors facilitate monitoring of test samples.
7. The left side of the unit features a 50mm diameter test port for connecting external power or signal cables (port size and quantity are optional).
8. Utilizes imported fan motors + high/low-temperature resistant aluminum alloy circulation fans. High-quality centrifugal fans ensure powerful air circulation, eliminating dead zones and achieving uniform temperature distribution throughout the test chamber.
9. Equipped with advanced safety and protection devices: earth leakage circuit breaker, over-temperature protector, phase failure protector, water shortage protector, low-water protection, short-circuit protection, current overload protection, along with audible/visual alarms and SMS alerts.

Structure and Material Specifications
The main system utilizes insulated sandwich panels, with combustion performance compliant with Class A1 or B2 standards of the “Classification of Combustion Performance for Building Materials.”
1. Wall Materials: All five sides of the chamber are assembled using double-sided color-coated steel insulated panels (computer color or snow white), fixed with aluminum support beams and aluminum profile edging. The floor remains untreated (insulation available upon customer request). High-temperature resistant silicone sealant is applied at joints to ensure effective chamber sealing. Aging test vehicles can be placed inside as required.
2. Single Door Opening: W800×2000mm (Double or single door available upon request).
3. Observation Window: 400×600mm tempered glass installed on the main door, enabling real-time monitoring of internal conditions during aging (or customized as required).
4. Heater Placement: Located within the ceiling air circulation duct, surrounded by fireproof insulation material. Utilizes PID temperature control modules. Upon reaching the required product temperature, the system automatically adjusts heater power based on indoor temperature fluctuations, complementing the insulation properties of the thermal panels to maintain precise and stable temperature at the set value.
Air Conditioning and Dehumidification System
The ventilation system complies with the “Code for Acceptance of Construction Quality of Ventilation and Air Conditioning Engineering” GB50243-2002 standard.
1. The hot air circulation system adopts a European-style design with left/right air outlets and a central return air duct, utilizing high-capacity fans for forced air circulation.
2. The ventilation system comprises separate exhaust and circulation systems, operating independently.
3. The exhaust system removes excess heat from the chamber when the internal temperature exceeds the product's required temperature.
4. The exhaust system employs a duct-and-fan integrated design concept. The circulation fan continuously drives convective air movement within the chamber; ensuring uniform indoor temperature distribution.
5. The heater is installed at the top of the aging chamber. Utilizing PID control, once the temperature reaches the product's required level, it dynamically adjusts the electric heating output power based on indoor and outdoor temperatures, significantly enhancing indoor temperature precision.
6. Enhanced quiet operation better ensures a favorable office environment and working conditions for operators.
