Product Description
SAINPOLY semi-closed greenhouses are customized for seedling cultivation and agricultural scientific breeding. Scientific breeding demands far higher environmental consistency than commercial cultivation. Comparative tests for different varieties require identical temperature, humidity and light conditions in each partition; even tiny environmental deviations will distort test data.
The semi-closed greenhouse delivers independent, highly consistent environmental control for each test partition: temperature fluctuation is controlled within ±0.3℃, humidity deviation below ±2%, and light uniformity exceeds 95%. Multiple breeding projects can run simultaneously with zero cross-interference between partitions. Optional HEPA filtration upgrades cleanliness to Class 100, satisfying high-cleanliness needs such as acclimatization of tissue-cultured seedlings. SAINPOLY provides full-process services covering test scheme planning, partition layout design, factory customization, on-site installation and acceptance verification.

Product Advantages
1
The main frame adopts Q235B and higher-grade standard steel with hot-dip galvanizing treatment, with a galvanized coating thickness ≥180g/㎡, far exceeding the standard for ordinary steel. A single upright column bears a load of several tons. The overall structure boasts a service life over 15 years, leading the industry in snow load resistance and wind uplift resistance.
2
Combining semi-closed enclosure, high-density precision sensor array and PID control algorithm, temperature deviation between partitions is kept below 0.3℃ to guarantee environmental consistency for comparative trials.
3
Each test partition features independent air intake, climate regulation and air exhaust. Parallel operation of multiple projects brings zero mutual interference and fully reliable experimental data.
4
HEPA filtration paired with positive-pressure clean channels meets stringent requirements for high-cleanliness scenarios including tissue-cultured seedling acclimatization and aseptic trials.
5
The self-production rate of core components reaches 90%. Supported by CE certification and 15 technical patents, a three-inspection system ensures zero defects before factory delivery.

A: Yes. Equipped with ultra-high-precision temperature control of ±0.3℃, independent zoned environmental control and two-out-of-three voting logic for sensors, it fully meets the environmental consistency requirements for comparative tests in variety breeding.
2
Q: Will there be cross-interference between partitions when multiple projects are running in parallel?
A: No. Adopting a fully isolated partition design, each zone is equipped with independent air intake, environmental control and exhaust systems. Multiple breeding projects can operate simultaneously without mutual interference.
3
Q: Can it meet the cleanliness requirements for tissue-cultured seedling acclimatization?
A: Yes. Optional HEPA filtration upgrades the cleanliness level to Class 100. Combined with a gradual environmental control transition solution, the survival rate of tissue-cultured seedlings during acclimatization is significantly improved.
4
Q: Do you provide customized design services for scientific research greenhouses?
A: Yes. Our engineers participate in the whole-process design and verification, covering test scheme planning, partition layout design and environmental control parameter setting.
5
Q: What is the minimum order area?
A: Research projects are available for small-area deployment. The exact area is customized according to experimental demands, and pilot demonstration projects are negotiable.
6
Q: Does the semi-closed greenhouse comply with international standards?
A: Yes. It has obtained CE certification, all construction materials conform to EU standards, and can satisfy the facility specification requirements of international agricultural research institutions.
