FAQ

The Topchill Box-Type Unit ZSI Low Temp is a versatile, low-temperature condensing unit designed for small-to-medium cooling needs. Available in 220V/1Ph and 380V/3Ph versions, it features Copeland ZSI-series scroll compressors, intelligent defrost control, and compact design—ideal for small cold storage, supermarkets, and dairy facilities.

CABINET STYLE

Dual-Voltage Flexibility

Offered in 220V/1Ph/50Hz (2HP-4HP) and 380V/3Ph/50Hz (2HP-3HP) versions, adapting to different power supplies (e.g., small shops, industrial sites).

No need for voltage converters, reducing installation costs and complexity.

Efficient Copeland Scroll Compressors

Equipped with Copeland ZSI-series compressors (ZSI06KQE, ZSI08KQE, ZSI11KQE) optimized for low temperatures (-30℃ to 0℃).

Delivers COP (Coefficient of Performance) up to 2.0, ensuring energy efficiency for long-hour operation.

All-in-One Control for Cold Storage

Full setup includes main control board, library temperature control board, and remote operation panel: Directly usable for cold storage (no extra distributors/controllers).

Operation panel features temperature display/setting, defrost control, and alarm functions—installable separately for easy monitoring.

Reliable Safety Protections

Comprehensive safeguards: Phase sequence/loss protection, overcurrent protection, compressor frequent start protection, and high/low pressure protection.

Fault alarm and inquiry: Buzzer alerts for issues (e.g., high discharge temperature); query function tracks fault history for quick troubleshooting.

Compact & Quiet Design

Small footprint (830×950×355mm for most models): Fits in narrow spaces (e.g., backrooms of convenience stores).

Low noise (≤65 dB[A]): Suitable for urban areas, hospitals, and residential-adjacent facilities.

Small-Scale Cold Storage

Convenience store cold storage: Stores frozen snacks, ice cream, and beverages at -18℃ to -25℃, with defrost control preventing frost buildup.

Small pharmaceutical storage: Maintains 2-8℃ for vaccines and medications in clinics or rural hospitals.

Supermarkets & Dairy Facilities

Milk tanks and dairy coolers: Keeps milk, yogurt, and cheese at 0-4℃ to preserve freshness.

Small refrigerated displays: Used for ready-to-eat meals and frozen desserts in convenience stores.

Food Processing Workshops

Small-batch food freezing: Ideal for bakeries (dough cooling) and delis (meat preservation) with low cooling capacity needs.

Laboratory cooling: Cools small equipment (e.g., sample storage cabinets) in research facilities.

Q: What is the MOQ?

A: MOQ is 1 piece, perfect for small businesses or test projects.

Q: What is the Lead Time?

A: 2-4 weeks. For customized voltage or control features, lead time is 3-5 weeks.
