Product Features

The SD Series Air Cooler-Water Defrost is designed for quick-freezing rooms, fruit and vegetable storage, and any cold storage requiring rapid defrosting. It offers three fin spacing options to meet high, medium, and low-temperature applications.

Model Classification:

SDL 4.5mm fin space: Suitable for fresh-keeping storage at ≥-5°C (te=-10°C, Δt=10K)
SDD 6mm fin space: Suitable for cold storage at ≥-18°C (te=-28°C, Δt=10K)
SDJ 9mm fin space: Suitable for freezing storage at ≥-25°C (te=-32°C, DT=7K)

Key Advantages

Durable & Corrosion-Resistant Housing: Constructed from high-quality steel with powder-coated finish for high strength, vibration resistance, and enhanced corrosion protection.
Optimized Heat Exchange Design: Features a staggered tube arrangement expanded mechanically to ensure tight contact between copper tubes and aluminum fins, delivering high heat transfer efficiency.
Uniform Water Distribution for Defrosting: Scientific structural design and water pan layout ensure even water coverage across the coil surface for consistent and thorough defrosting.
Effective Water Splash Prevention: Well-designed baffle plates prevent splashing of defrost water and minimize unwanted heat ingress.
Optional Long-Distance Air Duct & Explosion-Proof Motor: Available with extended air delivery ducts and explosion-proof motors for specialized application needs.
