Scene-Specific Solutions for Small-to-Medium Cooling Needs

The BF31-BF151 Series Air Cooling Chiller (0~20℃) is tailored for compact, low-capacity cooling scenarios:

Small Retail & Food Service: Cools convenience store display freezers and coffee shop milk fridges, maintaining 2~8℃ for fresh ingredients.

Medical & Laboratory: Powers small medical refrigerators (for vaccines and samples) and lab incubators, with 0~15℃ cooling to ensure biological safety.

Home & Small Business: Supports homebrewing setups (cooling wort to 18~20℃) and small bakery refrigerators (4~10℃ for dough storage).

Product Design & Material Advantages

Compact & User-Friendly Design

Lightweight & Small Size: Models like BFS31 (780×680×520mm, 115kg) fit under counters or in small storage rooms, ideal for space-constrained areas.

Easy Operation: Simple control panel with digital temperature display and one-touch start/stop, no professional training required.

Cost-Effective & Durable

Energy Efficiency: Low power consumption (Pe: 1.67~6.45kW) reduces monthly electricity bills by 20% vs. similar imported models.

Corrosion-Resistant Parts: Fan covers and compressor casings use galvanized steel, resisting humidity in kitchen/lab environments.

Technical Support & After-Sales Service

Quick Start Guide: Simplified manual with step-by-step installation and operation instructions, suitable for non-technical users.

Fast Spare Parts: Local distributors in 50+ countries stock common parts (e.g., fan motors, temperature sensors), ensuring same-day replacement.

Online Tutorials: YouTube channel with videos on "cleaning the condenser" and "replacing the filter drier" for DIY maintenance.

Affordable Warranty: 1-year full warranty; optional 1-year extended warranty for $99, covering labor and parts.

Q: The equipment shuts down suddenly during operation, with no overheating prompt or control unit alarm. What might be the problem and how to handle it?

A: It may be an open circuit in the circuit. Inspect the circuit breakpoints in sections, focusing on easily worn wires and joints, and repair or replace the wires after finding the issue.

Q: If the wires are abnormal due to phase loss when the equipment starts, what are the key steps for emergency handling?

A: The key step is to turn off the power immediately, check the phase connection of the three-phase power supply (e.g., loose phase wires, phase loss), and restart the equipment only after confirming the phase is normal.

Q: If the terminal board is burned due to frosting, what else needs to be adjusted simultaneously besides replacing the terminal board?

A: Adjust the equipment's defrosting system simultaneously to avoid severe frosting again; at the same time, take anti-frost measures for the new terminal board (e.g., install frost shields).

Q: If the wires heat up severely and the wire diameter is too small, and the wires cannot be replaced immediately, what temporary measures can be taken?

A: Temporary measures include reducing the equipment load (e.g., lowering operating power), shortening the single operation time to avoid wire overload; at the same time, purchase wires matching the power as soon as possible for replacement.
