Frequently Asked Questions
What is the difference between W-SD, W-SL, and W-SJ air coolers?
The three series are designed for different temperature ranges. W-SD is for medium-temperature cold storage (-5°C to 5°C), suitable for fresh foods and vegetables. W-SL is for low-temperature storage (-15°C to -25°C), ideal for beef, mutton, fish, and seafood. W-SJ is for ultra-low temperature storage (-25°C to -40°C), used mainly for quick-frozen poultry, seafood, and dairy products.
What refrigerants are compatible with the W-series water defrost air coolers?
The W-series air coolers are compatible with multiple refrigerants including R404A, R507A, and R22, giving users flexibility to match the unit with their existing refrigeration compressor systems.
What installation and blowing types are available for the W-series air coolers?
The W-series supports both ceiling-mounted and floor-stand installation. Ceiling-mounted options include Oblique Side Blow, Standard Side Blow, and Double Side Blow. Floor-stand options include Standard Top Blow and Vertical Side Blow, allowing flexible configuration based on cold storage layout requirements.
How does the water defrost system work and why is it energy efficient?
The water defrost system uses warm water to melt frost accumulated on the evaporator coils. Compared to electric defrost heating, this method typically consumes less energy, which reduces overall operating costs and improves the long-term efficiency of cold storage operations.
Can the fan motor and fin type be customized for the W-series air coolers?
Yes. The W-series offers both MaEr and EBM fan motor options. For fins, customers can choose between standard light foil, blue hydrophilic aluminum foil, or other available AL foil types to suit specific cold storage environments and performance requirements.
What evaporating area sizes are available in the HT-WS series specification?
The HT-WS series covers a wide range of evaporating areas from 30 m² up to 670 m², with standard and optional configurations for defrost type, installation blow type, fan motor brand, fan type, and fin material. For configurations not listed in the specification table, customers are encouraged to consult YSHT directly for custom solutions.
