Why choose Chiencheng
Against comprehensive first-tier brands like Haier and Zhongke Meiling, Chiencheng differentiates through deep expertise in the ultra-low-temperature niche.
Deep models validated by SOE
-150℃ capability validated through public tenders of a central SOE engineering group; full specs and parameters available.
Cascade + Stirling dual routes
Mainstream cascade for high-capacity long-term storage; Stirling for small-volume, heat-limited and mobile scenarios.
Enhanced heat dissipation
Optimized cooling structure tolerates 32℃ equipment rooms short-term, reducing summer heat alarms and drift.
Flexible customization
Comm interfaces, door orientation, special alarms and multi-country voltage can be adjusted per project; warranty preserved.
Multi-brand selection agency
Authorized for Haier and Hisense — can supply both brands' full cold-chain lines and recommend by budget and scenario.
Project-based service
Site survey, installation, commissioning and training; deep models with 15-day delivery commitment.
Four steps: from requirement to maintenance
Equipment selection involves site, power, sample type and compliance. We split it into four steps, each with a clear deliverable.
Requirements
Confirm stored object, temperature zone, volume, site dimensions and power — and whether customization is needed.
Selection & configuration
Match models within the zone; define compressor, liner, monitoring module and alarm options.
Delivery & installation
Deliver on schedule, install and commission on site, with operation training and documentation.
Operation & support
After-sales response and maintenance; cold-room projects can include remote monitoring and over-temp alarms.
