Constant Temperature and Humidity Test Chamber

LORDERAN Constant Temperature and Humidity Test Chamber with Water Recirculation, 0-100°C, 20%-98% RH Precision Humidity Control Chamber for Electronics, Material Test and Microbial Culture

SKU: HWS150
Availability: In stock
Brand: Lorderan

Capacity · 150L

Power · 110V

A constant temperature and humidity chamber for the long, steady tests that cannot be interrupted: stability studies, shelf-life testing, material conditioning and bioproduct storage. It holds 0 to 100 °C and 20 to 98 %RH with ±0.5 °C fluctuation, while a variable-frequency compressor, thick insulation and a water recirculation system keep running costs and refills low. Four sizes from 150 to 1000 L, with a 2-year warranty.

The stable damp-heat working zone

Temperature runs from 0 to 100 °C. Where temperature and humidity are controlled together, the chamber holds the coloured zone steadily for weeks. The three markers are the ICH stability conditions many labs run every day; all three sit comfortably inside.

20 %RHis reachable from 60 to 85 °C; at lower temperatures the minimum humidity rises, as the zone boundary shows.

Outside the zone?Conditions beyond the guaranteed range need a feasibility check. Ask our engineers before you order.

Choose a size

Same range, controller and protection on every size. Front elevations drawn to the same scale.

Ready for long-term stability studies

Typical ICH conditions for drug substances and products, all inside the controlled zone, held for months at low running cost.

Long-term25 °C / 60 %RH

Real-time stability at standard storage conditions.

Intermediate30 °C / 65 %RH

When accelerated results show a significant change.

Accelerated40 °C / 75 %RH

Faster degradation for early shelf-life estimates.

Conditions as commonly specified in ICH Q1A(R2). Your protocol defines the exact conditions and durations.

Water recirculation: weeks without refilling

Condensate and unevaporated water are collected and pumped back to the humidifier reservoir, for more than 80% better water utilization, less DI or RO water, no external drain line and unattended running for weeks or months.

Engineered to run cheaply for months

Energy-saving design and the details that make long tests simple.

Variable-frequency compressor

Output follows the load instead of cycling at full speed, for steadier control and lower energy use.

Thicker insulation

Low-conductivity insulation reduces the work the heater and compressor must do.

Automatic water refill

A recirculation tank feeds the humidifier automatically.

Optimized air duct

Even airflow for better temperature and humidity uniformity.

SUS 304B interior

Acid- and corrosion-resistant stainless steel that wipes clean.

R290 refrigerant

A natural refrigerant, in an air-cooled hermetic system.

Touch screen, PT100

Clear touch control with a platinum resistance PT100 sensor.

100 mm test hole

Run cables to powered samples during the test.

Low power, standard sockets

Current draw is low enough for ordinary lab circuits.

Questions buyers ask

Straight answers before you order.

Can it run ICH stability conditions?

Yes. 25 °C / 60 %RH, 30 °C / 65 %RH and 40 °C / 75 %RH all sit inside the controlled temperature and humidity zone.

Which humidity is possible at which temperature?

See the control range chart: humidity is controlled from 15 to 85 °C, up to about 90 %RH; the minimum humidity rises at lower temperatures. Outside the zone, ask our engineers.

How often do I need to add water?

Rarely. The water recirculation system reuses condensate and unevaporated water and refills the humidifier automatically, for weeks or months of unattended running.

Which voltage should I order?

Every size is offered in 110 V and 208–240 V versions. The 150 L and 250 L draw 6.8 A at 220 V; the 500 L and 1000 L draw 11.4 A at 220 V.
