FAQ

The Topchill Box-Type Unit ZF Low Temp is a compact, high-efficiency condensing unit powered by Copeland scroll compressors, engineered for harsh low-temperature environments (-30℃ to 50℃). With IP66 protection, corrosion-resistant stainless steel, and IoT connectivity, it delivers 35% energy savings—ideal for retail, cold storage, and cold chain logistics.

CABINET STYLE

Energy-Saving Copeland Compressor

Equipped with Copeland ZF-series scroll compressors (ZF13KQE, ZF15KQE, ZF18KQE) that reduce energy consumption by 35% vs. traditional reciprocating compressors.

Optimized for low temperatures (-30℃), ensuring stable cooling even in extreme ambient conditions.

Harsh-Environment Durability

IP66-rated cabinet: Dust-tight and water-resistant, suitable for outdoor or coastal areas (resists salt spray per ASTM B117).

Corrosion-resistant stainless steel components (e.g., fan blades, coils) extend service life to 10+ years.

Flexible Control Options

Customizable electrical configurations: Choose standalone main control board (for supermarkets, milk tanks) or full setup (main control + library temp board + operation panel) for cold storage (no extra controllers needed).

Fan speed control: Automatically adjusts condenser fan speed based on condensing temperature, saving 15% fan energy.

Comprehensive Safety & Monitoring

Multi-protection features: Phase sequence/loss protection, overcurrent protection, compressor frequent start protection, and high/low pressure protection.

Real-time parameter query: Check compressor current, discharge temperature, and condensing temperature via the operation panel.

IoT-Ready Connectivity

Supports remote monitoring and management via mobile app: Track temperature, receive fault alerts, and optimize performance—ideal for cold chain fleets.

Food processing plants: Cools processing lines (e.g., meat cutting, bakery dough cooling) in high-humidity environments.

Connected Cold Chain Logistics

Refrigerated trucks and containers: IoT connectivity allows fleet managers to remotely monitor cargo temperature (real-time updates), ensuring pharmaceuticals and perishables stay within safe ranges during transit.

Q: What is the MOQ?

A: MOQ is 1 piece, suitable for small cold storage projects or large fleet orders.

Q: What is the Lead Time?

A: 2-4 weeks. For bulk orders (10+ units), lead time may extend to 5 weeks, with production updates provided weekly.

Q: What Are the Payment Terms?

A: Orders >$10,000: 30% deposit, 70% before goods loading.

Orders ≤$10,000: 100% advance payment.

Q: Can the Unit Be Used Outdoors?

A: Yes. The IP66 rating and corrosion-resistant design make it suitable for outdoor installation (e.g., roof of supermarkets, cold storage yards).

Q: How to Troubleshoot a Compressor Start Failure?

A: Check phase sequence (correct if reversed).

Verify power supply (380V stable).

Inspect overcurrent protection (reset if tripped).

Contact technical support if the issue persists.
