Walk-In Environmental Test Chambers.
Large-volume temperature and humidity environments for testing complete systems, sub-assemblies and products under accelerated climatic conditions.
Bring full-scale products inside a controlled climate.
ISOTECH Walk-In Environmental / Climatic Chambers reproduce temperature and humidity conditions for assessing product suitability, reliability and durability under accelerated environmental exposure.
Large test spaces accommodate products, sub-assemblies and complete systems for research, production validation and reliability programmes. Modular sealed panels, uniform airflow, efficient refrigeration and programmable control support repeatable operation.
The product is published for IEC, IS, ASTM, MIL-STD and JSS-aligned work. The exact test method, performance configuration and chamber dimensions should be confirmed during technical review.
One chamber. Four engineered zones.
The test room, conditioning plenum, service plant and controlled access work as one full-scale environmental system.
Full-scale specimen room
Configurable 3,000 L to 250,000 L space for products, sub-assemblies or complete systems.
Conditioning plenum
A detachable plenum cover provides service access while only the fan impeller is exposed inside.
Heating, cooling & humidity
Jacket heaters, steam humidification, dehumidification and mechanical refrigeration create the profile.
Safe walk-in entry
Viewing, illumination, positive-cam hardware and an internal safety-release exit device protect operation.
A sealed room built around the operating range.
The vapour- and air-tight interior uses high-gloss polished 304-grade stainless steel with welded, corrosion-resistant, easy-clean surfaces and adjustable or removable shelving. The exterior may use CRCA, GI or stainless steel with an electrostatic powder finish.
Mineral-fibre insulation
Environmentally friendly, asbestos-free and CFC-free mineral-fibre insulation is published for temperature ranges above 80°C, together with a front-opening door, double silicone seals, multi-pane viewing window, auto-cut-off defogging heat and illumination.
80 mm prefabricated PUF panels
Foamed-in-place, CFC-free polyurethane insulation is published for ITWENV models below 80°C, with a flush-mounted door, viewing glass, positive-cam lift hardware and a safety-release exit operable from both sides.
Inner shell
16 or 18 SWG, 304-grade stainless-steel test space with vapour-tight welds and finished edges.
Outer shell
16 or 18 SWG CRCA, GI or stainless steel with a fine electrostatic powder-coated finish.
Door sealing
Double-lined A-grade silicone gaskets support leak-resistant closure and stable chamber performance.
Standard provisions
Measurement cable ports, required shelves and a drain outlet with suitable fittings are published.
Uniform air, active moisture and industrial refrigeration.
The conditioning package is designed to minimise variation across large specimens and maintain repeatable temperature-humidity profiles.
High-rate air circulation
A correctly sized fan motor and impeller distribute conditioned air throughout the walk-in volume.
- Uniform temperature and humidity
- External drive motor
- Impeller exposed in plenum only
- Detachable maintenance cover
Heating and humidification
Fast-response jacket heaters raise chamber temperature without direct radiant exposure to specimens.
- Uniform heat distribution
- No direct heater radiation
- Low-pressure steam humidification
- Auto-float water reservoir
Active dehumidification
A refrigeration-based dehumidification system controls lower relative humidity and helps prevent condensation on specimens.
- 10% to 98% RH range
- 2% to 3% RH deviation
- ±3% humidity gradient
- Continuous water management
Mechanical refrigeration
Single-stage or cascade systems use water- or air-cooled heat rejection for model-dependent low-temperature operation.
- R404A and R23 refrigerants listed
- Hermetic or semi-sealed compressor
- Electronic expansion valve
- HP/LP cut-off and oil return
Programme, measure and record the full-scale environment.
The large-screen programmable controller combines TFT LCD touch and key input with programme graphics, history trends, ramp-and-soak profiles and cyclic operation.
Profiles and cycles
Multiple programmes and profile segments support ramp, soak and repeatable cyclic conditioning.
Connected operation
RS-232/485, networking and USB support external hardware and fast data transfer.
PT100 and RH sensing
PT100 measures temperature; a high-precision continuously wetted humidity sensor improves service life through self-cleaning action.
LO and RE families
LO identifies logic-programmable models. The source also references single-set microprocessor PID temperature-humidity control for RE configurations.
Protection around people, specimens and plant.
Independent shutdown functions address access, temperature, electrical faults and refrigeration pressure while the internal exit release supports walk-in safety.
Four published low-temperature configurations.
Each model supports the same published humidity and capacity range while the lower temperature limit changes from -10°C to -70°C.
| Model | Temperature range | Humidity range | Test-space range |
|---|---|---|---|
| ITWETC -70 LO | -70°C to +180°C | 10% to 98% RH | 3,000 L to 250,000 L |
| ITWETC -40 LO | -40°C to +180°C | 10% to 98% RH | 3,000 L to 250,000 L |
| ITWETC -20 LO | -20°C to +180°C | 10% to 98% RH | 3,000 L to 250,000 L |
| ITWETC -10 LO | -10°C to +180°C | 10% to 98% RH | 3,000 L to 250,000 L |

Yes. Chamber dimensions, temperature range, humidity performance, access, controls, plant arrangement and project-specific options can be engineered around the requirement.
ISOTECH publishes both standard model families and custom-designed solutions. The final size and performance package are selected from the specimen, profile and facility requirements.
The product page references IEC, IS, ASTM, MIL-STD and JSS. Confirm the precise method and compliance configuration during technical review.
The published chamber focuses on temperature and humidity. ISOTECH's broader portfolio also includes altitude, UV, thermal-shock and other specialist environmental systems.
Use the scheduled inspection, calibration, cleaning and service plan supplied for the selected refrigeration, humidification, sensors, safety devices and chamber structure.
Lead time depends on chamber size, performance complexity, options and current production demand. ISOTECH can provide a project timeline after technical scope confirmation.
