Copeland ZB Scroll Condensing Units | R404A Medium Temp Cold Room Condensing Unit

The condensing unit is the core power source of the whole cold storage refrigeration system, determining the stable cooling capacity, operation energy consumption and long-term service life of the warehouse. Among all medium-temperature refrigeration equipment, Copeland ZB scroll condensing units have become the mainstream choice for fruit, vegetable and dairy fresh-keeping cold rooms for their stable performance, low noise and high efficiency.

Many cold storage owners encounter frequent high-pressure alarms, insufficient cooling speed and high power consumption caused by mismatched condensing units. Our Kubao Copeland ZB series scroll condensing units are professionally optimized for medium-temperature cold storage working conditions, solving common pain points such as poor heat dissipation and unstable load, and creating a constant-temperature storage environment for fresh goods.

Our full ZB series condensing units adopt original Copeland ZB scroll compressors, matched with self-developed high-efficiency condenser systems, with three core engineering optimizations:

1. Diversified Condenser Structure Design

   We provide three mainstream outlet types to adapt to different factory installation environments:

   • Standard side air outlet model: Compact size, low cost, suitable for ordinary factory workshops with good ventilation;
   • U-type top discharge box unit: Enlarged heat exchange area, stronger heat dissipation capacity, ideal for high-temperature summer workshops and poorly ventilated machine rooms;
   • Special export version: Optimized internal wiring, packaging and voltage standards, convenient for overseas distributors’ bulk export orders.

   Models above 4HP are equipped with double fans to balance air volume and reduce running noise, effectively lowering unit high-pressure risks in hot weather.

2. Complete Optional Supporting Refrigeration Components

   To form a fully matched cold storage system, we support multiple optional accessories for ZB units:

   • Oil separator + liquid sight glass combination: Avoid lubricating oil entering the evaporator, real-time observation of refrigerant liquid level, essential for long-term continuous operation;
   • Danfoss supporting kits including filter drier and solenoid valve: Block moisture and impurities in the pipeline, protect the compressor and extend service life;
   • Special complete electric control box: Integrate crankcase heating, high-low pressure protection, automatic delay startup, realizing one-click automatic operation of the whole unit.
3. Stable Medium-temperature Working Condition Matching

   All ZB scroll units use R404A and R507 refrigerants, perfectly matching 0~5℃ fresh-keeping cold rooms. The scroll compressor structure features stable load capacity, no liquid slugging risk under normal operation, and can continuously run 24 hours without frequent shutdown protection. The power range covers 2HP to 40HP, supporting single-unit independent cold room or multi-unit parallel rack systems for large-scale fresh storage warehouses over 1000 cubic meters.

We divide ZB series models according to cold storage volume to help customers quickly select the right unit:

• Small fresh cold room (20–150m³): ZB15/21/26/33/38KNE 2HP–5HP single machine, side air outlet standard model preferred;
• Medium fruit and vegetable warehouse (200–500m³): ZB45/57/76KQE 6HP–10HP U-type top discharge unit, better heat dissipation for long-hour operation;
• Large industrial fresh storage (above 500m³): 12HP–40HP ZB parallel scroll units, matched with centralized PLC control system to realize energy-saving variable load operation.

For food processing factories, agricultural fresh markets and refrigeration distributors, ZB scroll condensing units bring obvious long-term cost advantages:

1. Low failure rate: Scroll compressors have fewer vulnerable parts than piston compressors, reducing after-sales maintenance frequency and spare parts replacement costs;
2. Energy-saving design: High-efficiency heat exchange coil and energy-saving fan reduce daily power consumption by 10%–15% compared with ordinary old-style units;
3. Convenient maintenance: The integrated box structure adopts detachable panels, technicians can quickly inspect compressors, filters and electrical components without removing the whole unit;
4. Complete spare parts supply: We support separate drop-shipping of all matching accessories for global distributors, including compressors, fan motors, pressure controllers and electrical parts.

Our ZB condensing units are fully compatible with DL series medium-high temperature air coolers and TX series mechanical expansion valves. According to the warehouse volume and unit horsepower, we can provide one-stop complete cold storage solutions including condensing unit, air cooler, expansion valve and electric control system. Customized schemes such as BT4 explosion-proof type and water-cooled condenser are also available for special project demands.

Whether you are building a small fresh cold room for a supermarket, a large fruit distribution warehouse, or purchasing refrigeration equipment as an overseas distributor, Copeland ZB scroll condensing units can provide stable, efficient and cost-effective refrigeration power. With diversified structural options, complete supporting accessories and reliable medium-temperature working condition performance, our ZB series units are the ideal core equipment for all fresh cold storage projects.
