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®

The chamber requires a dedicated AC 220V, 50Hz power supply and an ambient temperature between 5°C and 30°C for safe operation. All ventilation openings, test ports, and drain areas must remain unobstructed to prevent overheating and maintain humidity control accuracy.

Temperature Control Limitation: The CH model lacks active refrigeration and can only control temperature from RT+10°C to 85°C.
Ambient Temperature Requirement: The working environment must be maintained between 5°C and 30°C as specified.
Power Supply Constraint: The chamber must be connected to a dedicated AC 220V, 50Hz circuit with a 2050W capacity and proper grounding.
Ventilation and Access Requirement: Air inlets, test ports, shelving, drain areas, doors, and controller surfaces must remain accessible for cleaning and maintenance.

HowTo

This procedure describes initial setup and safe operation of the BPS-250CH constant temperature and humidity chamber. Follow these steps to install, power, and program the chamber for controlled environmental testing.

Required Equipment: Lifting equipment (e.g., forklift or pallet jack)

Inspect the installation site
Inspect the installation site to confirm it meets the required dimensions of 750 x 900 x 1580 mm and can accommodate the chamber with adequate clearance.
Unload and position the chamber
Use suitable lifting equipment to unload and position the chamber on a stable, level surface.
Connect the power supply
Connect the chamber to a dedicated AC 220V, 50Hz power supply with proper grounding.
Ensure accessibility
Ensure that all air inlets, test ports, shelving, drain areas, and doors are accessible for operation and maintenance.

FAQ

What is the practical lower temperature limit of the BPS-250CH chamber given that it is a 'CH' model without stated refrigeration, and how does this affect applications requiring sub-ambient conditions?

The BPS-250CH model operates from RT+10°C to 85°C, meaning the minimum achievable temperature is 10°C above ambient. The source explicitly states 'No refrigeration function is stated for this CH model', so it cannot cool below ambient. For sub-ambient testing, a different model with active refrigeration would be required.

Can the BPS-250CH chamber be integrated with a laboratory's existing data acquisition system via optional communication interfaces?

Yes, the chamber supports optional RS485 communication interface and software for data output and monitoring. The touchscreen controller also stores up to 100 programs and 1000 segments with curve display, allowing external integration. These options must be specified at order as per the configuration note.

What are the critical installation infrastructure requirements for the BPS-250CH chamber regarding power supply, ventilation, and workspace?

The chamber requires a 2050W, AC 220V/50Hz power supply. The working environment must be 5-30°C. External dimensions are 750x900x1580 mm, so adequate clearance for ventilation and maintenance access is needed. The unit is shipped upright and requires suitable lifting equipment for positioning.

Assessment

This 250 L constant temperature and humidity chamber provides programmable touchscreen control with up to 100 programs and 1000 segments, combined with an imported 304 mirror-finish stainless-steel interior for durability and hygiene. However, the humidity range is restricted to 80–95%RH and the unit lacks refrigeration, limiting temperature control to above ambient (RT+10 to 85°C), which constrains its applicability for low-humidity or sub-ambient testing.

Positive

Large programmable controller capacity: The touchscreen controller supports up to 100 programs, 1000 segments, and 999 cycle steps, enabling complex staged environmental protocols for incubation, cultivation, and stability studies.
Imported stainless-steel chamber interior: The 304 mirror-finish stainless-steel interior provides corrosion resistance, easy cleaning, and long-term durability for repeated laboratory use.

Trade-offs

Narrow humidity control range: Humidity is limited to 80–95%RH, making the chamber unsuitable for applications requiring low-humidity conditions or precise dew-point control below 80%RH.
No refrigeration for sub-ambient operation: This CH model lacks a refrigeration system, restricting temperature control to RT+10 to 85°C; it cannot achieve temperatures below ambient, limiting its use for cold-condition testing.
