Performance Features

Color touchscreen operation helps simplify program editing, parameter review and real-time curve observation during chamber use. This improves parameter review, setpoint editing and day-to-day operation in controlled chamber workflows.
Large program capacity supports staged environmental methods that need repeated cycles and multiple segments. This supports staged test methods and repeatable laboratory workflows that need cycle-based control.
PID auto-tuning helps correct temperature and humidity deviations quickly for more stable chamber control. This supports humidity-sensitive incubation, cultivation, conditioning and stability-study applications.
Balancing-control refrigeration and imported stainless-steel chamber construction support reliable long-duration operation. This helps support repeated cleaning, chamber hygiene and long-duration laboratory use.
Independent alarm and protection functions cover over-temperature, overload, over-current, fan and compressor conditions. This helps maintain dependable low-temperature performance and stable chamber recovery during repeated use.
Optional communication, printer and wireless-alarm functions make it easier to store, replay and supervise chamber records. This reduces operational risk by helping protect samples and notifying operators when abnormal conditions occur.

APPLICATION SCOPE: Suitable for scientific research, biotechnology tests, pharmaceutical packaging, industrial raw-material studies and product lifetime evaluation in universities, research institutes, pharmaceutical quality-control laboratories, agricultural research programs and industrial test environments that require controlled chamber operation.

HANDLING: Confirm installation space against 750 x 900 x 1580 mm, prepare the specified power supply, and keep air inlets, test ports, shelving, drain areas, doors and controller surfaces accessible for cleaning and maintenance. Every unit is shipped with reinforced packaging to reduce movement and impact during transport; keep the packed chamber upright and use suitable lifting equipment during unloading and positioning.

IMPORTANT NOTICE: Confirm the exact controller type, lighting form, humidity function, communication option and accessory package before ordering. Any displayed amount refers to the chamber body only and does not include freight. Freight is quoted separately and should be confirmed according to the delivery location and shipping method.

Supplier: Atomfair

Brand: ATOMFAIR®

This chamber requires a controlled ambient environment and a dedicated power supply for safe operation. Proper handling during transport and positioning is essential to prevent damage to the refrigeration system.

Ambient Temperature Range: The working environment must be maintained between 5°C and 30°C to ensure stable refrigeration and humidity control.
Power Supply Requirements: A dedicated AC 220 V, 50 Hz power supply with a capacity of 2700 W and proper grounding is required.
Ventilation and Access: Air inlets, test ports, and controller surfaces must remain unobstructed for adequate airflow and operational access.
Transport Orientation: The chamber must be kept upright during transport and positioning to prevent refrigerant migration or compressor damage.
Interior Hygiene: The 304 stainless-steel interior should be cleaned regularly to maintain chamber hygiene and prevent corrosion.

HowTo

Installation involves verifying space and power requirements, unpacking with care, and positioning for accessibility. Programming the touchscreen controller with staged parameters enables automated environmental testing.

No, the humidity control range is 35%RH to 95%RH with a deviation of ±3%RH. The chamber does not support humidity below 35%RH as per the product specifications.

What are the installation space and power requirements for the 250L constant temperature and humidity chamber?

The external dimensions are 750 x 900 x 1580 mm, and the power requirement is 2700 W at AC 220V, 50 Hz. The working environment temperature should be between +5°C and 30°C. Ensure adequate clearance for air inlets and maintenance access.

Assessment

The Atomfair BPS-250CA (SKU AF-LE-E-BPSC-0250-CA25) is a 250 L programmable temperature and humidity chamber with balancing-control refrigeration, a 304 stainless steel interior, and a color touchscreen controller supporting up to 100 programs and 1000 segments. It provides -20 to 100°C temperature control and 35% to 95% RH humidity control, making it suitable for incubation, stability testing, and climate simulation, but requires careful attention to power (2700 W, 220 V, 50 Hz) and ambient temperature (5-30°C) constraints.

Positive

Large programmable control capacity: The touchscreen controller supports up to 100 programs, 1000 segments, and 999 cycles with a maximum segment time of 99 h 59 min, enabling complex staged test protocols and repeatable cycles for long-duration studies.
Balancing refrigeration and stainless steel construction: The balancing-control refrigeration system combined with an imported 304 mirror-finish stainless steel interior provides stable temperature and humidity control, supports repeated cleaning, and ensures reliable long-term operation in laboratory environments.

Trade-offs

Infrastructure and power requirements: The chamber requires a 2700 W, AC 220 V, 50 Hz power supply and an ambient operating temperature range of +5 to 30°C, necessitating dedicated electrical and environmental planning in the laboratory.
Limited humidity and temperature precision: Humidity control is specified at ±3% RH deviation, and temperature uniformity is ±0.5°C at high temperatures and ±1°C at low temperatures, which may be insufficient for applications requiring tighter tolerances.
