Environmental simulation chamber for testing materials by simulating conditions at desired temperature and humidity levels

This series of environmental simulation chambers is developed with a focus on energy efficiency and sustainable performance. A modern refrigeration system works alongside an advanced control platform to maintain stable conditions with less power consumption. The design helps ensure precise temperature and humidity management, making these chambers a dependable choice for demanding testing environments where consistency and lower operating costs are priorities.

Standard Configuration

1 cable port (Ø100 mm), with grey flexible rubber plug and cover
Hour meter
1 observation window (insulating glass with transparent heating film)
4 caster wheels
4 leveling feet
2 sets of specimen racks
USB port
1 sample power control terminal
1 RS-485 communication port
1 RJ-45 Ethernet port

Features

Wide humidity control range, supporting conditions up to 95 °C and 95% RH
Dual PID algorithm that reduces overall energy consumption by up to 40%
High-precision climate control with temperature fluctuation within ±0.5 °C, temperature deviation better than ±1.5 °C, and humidity deviation within ±3.0% RH
Low operating noise, reaching just 63 dB(A)
Advanced ELV electronic expansion valve technology adjusts compressor output intelligently, helping lower energy use and extend compressor lifespan

Design Highlights & Functional Components

A large observation window with multi-layer tempered glass and built-in heating prevents fogging, so you can easily monitor samples while testing is underway.
Adjustable stainless steel racks make it simple to organize samples of different sizes. For heavier loads, reinforced shelves are available that support up to 80 kg per level.
The interior of each test chamber is assembled with robotic welding for strong, seamless joints, and uses high-integrity seals to maintain consistent conditions over long test cycles.
The water supply system includes both a fixed tank and a removable handheld reservoir that can be refilled without interrupting operation. For added convenience, an automatic water supply option is also available.
