1.Simple and reliable, Excellent effect.
2.Uses circulating water to quickly melt frost, keeping coils clean and maintaining stable heat exchange. It greatly improves cooling efficiency and reduces downtime for cold rooms and industrial refrigeration systems.
3.When defrostinging. the temperature goes up slowly, it would suit the quick freezing cold storage better
4.Water is sprayed onto the outer surface of the evaporator by a water pump to melt and wash away the frost layer.
5.Simple operation and short defrosting time
6.Lower energy consumption than electric defrost, reducing long-term operating costs. Stable structure and anti-corrosion design ensure reliable performance and long service life.
7.Suitable for cold storage, food processing, and logistics warehouses. Supports customization to match different refrigeration units and installation requirements.
Simple structure, smooth drainage, and easy control. With 14+ years of manufacturing experience, our products feature stable quality and low maintenance.

1.Cold Storage Warehouses
Suitable for fresh-keeping and low-temperature cold storages. It works efficiently in high humidity, quickly defrosts coils, and keeps stable temperature and humidity to protect stored goods.
2.Food Processing Plants
Perfect for seafood, meat, dairy and frozen food processing lines. It meets hygienic standards, runs steadily, and supports continuous production with reliable cooling.
3.Cold Chain Logistics Centers
Ideal for distribution centers and frozen storage hubs. It adapts to frequent door opening, maintains stable cooling, and ensures smooth cold chain operation.
4.Commercial Refrigeration
Applied in supermarket cold rooms, large freezers and beverage storage units. It saves energy, reduces maintenance, and provides quiet and steady cooling.
Turn on the main power and set proper working temperature on the control panel. Start the unit normally, and the defrost system will run automatically. For manual defrost, press the defrost button, keep water supply smooth and drain unblocked. After defrosting, the unit will resume cooling automatically. Stop the machine before maintenance, and keep coils clean regularly.
1.Ensure the water supply is stable and clean before operation.
2.Start the defrosting function only when the unit is in standby mode.
3.Control defrosting time properly to avoid excessive water or frost residue.
4.Regularly check drainage and clean the nozzle to keep smooth.
5.Follow rated voltage and parameters to ensure safe and efficient working.
Q:When to use water defrosting?
A:When frost builds up and affects cooling efficiency.
Q:How long does defrosting take?
A:Usually 5–10 minutes, depending on frost thickness.
Q:Can I run cooling during defrosting?
A:No. Please pause cooling first.
Q:What water pressure is suitable?
A:0.2–0.4 MPa for stable and effective defrosting.
Q:Why is defrosting incomplete?
A:Check water pressure, nozzles, and drainage for blockages.
Q:How to maintain it?
A:Clean nozzles and drain regularly to ensure smooth water flow.
