Low Noise Reliable Performance Oblique Draft Industrial Blast Freezer Evaporator

Overview

Designed to eliminate direct airflow on goods while accelerating freezing cycles, this industrial-grade equipment combines low noise operation, reliable performance, and customizable configurations to protect product integrity—making it a top choice for high-value applications like ice cream production, flower preservation, and pharmaceutical freezing. With a cooling capacity range of 15 ~ 200 kW and compatibility with multiple refrigerants (HFC, NH₃, CO₂, etc.), it adapts seamlessly to diverse cold storage needs while minimizing moisture loss and maintaining consistent quality.

The adjustable-angle plenum can effectively avoid direct blowing of goods and reduce dry consumption.

The 304 stainless steel protective net meets hygiene requirements and can prevent debris from entering the equipment, which can affect the operation effect.

Details

Innovative Oblique Airflow Design

At the core of this evaporator is the adjustable-angle plenum chamber, a unique feature that redirects airflow to avoid direct blowing on delicate products. This design not only reduces dry consumption (moisture loss) by up to 30% but also creates optimal internal/external air circulation, ensuring faster and more uniform freezing. The reinforced plenum structure guarantees vibration-free operation, preventing damage to fragile items like pastries or flowers during the freezing process.

Premium Corrosion-Resistant Materials

Constructed with high-quality materials including 304/316 stainless steel, titanium, aluminum, and copper, the evaporator offers exceptional durability and compliance with strict hygiene standards. The 304 stainless steel protective filter mesh prevents debris from entering the system, safeguarding performance and extending service life. Its heavy-duty build supports 24/7 reliable operation in demanding industrial environments, while corrosion-resistant coatings (epoxy, powder coated, Al-Zn coated) ensure longevity even in high-humidity settings.

Smart Defrost & Versatile Mounting

Equipped with a multi-mode defrost system (electric, hot gas, water, glycol, etc.), the evaporator enables fast and uniform defrosting to avoid ice accumulation. The deep, sloped water tray prevents overflow and dripping, maintaining a clean operational environment. Additionally, optional support structures allow flexible ceiling or floor mounting, adapting to various cold room layouts and spatial constraints—whether for small-scale production facilities or large distribution centers.
