Main Features Of Koller Blast Freezer

Intelligent & Automated Control System

Equipped with a fully automatic digital control system for the refrigeration unit, it supports precise temperature management and automatic defrosting functions.

Various Door Types and Sizes.

The cold storage doors come in sliding doors, hinged doors, and glass doors, and the door sizes can be customized according to customer requirements.

Integrated Containerized Design

The cold storage features a standard container-like structure, which allows for factory pre-assembly and complete system integration to guarantee quality. Also, the unit can be easily relocated if needed, offering great operational flexibility.

High-Performance Insulation

The panels are manufactured using high-pressure polyurethane foaming technology, providing superior thermal insulation. This robust structure minimizes cold loss, reduces energy consumption, and ensures the durability of the storage environment under various working conditions.

Reliable Core Components

The refrigeration unit adopts an all-in-one integrated system and is powered by globally recognized compressors, including Copeland and Bitzer. This ensures high operational stability, low failure rates, and extended service life, even in demanding industrial environments.

Wide Capacity Range & Versatility

The storage capacity ranges from 3 tons to 100 tons, making it suitable for a diverse array of products, including ice, fruits, vegetables, seafood, and meat. It is an ideal solution for both commercial cold chain logistics and industrial processing applications.

Wide Application of Blast Freezer

Sashimi-Grade Tuna Preservation

Instant ultra-low freezing locks intracellular moisture, ensuring juiciness and texture after thawing for raw consumption.

IQF (Individually Quick Frozen) Flash Freezing

Uses ultra-low airflow to freeze individual pieces separately without clumping, preserving shape and nutritional value.

Aerospace Material Extreme-Temperature Testing

Simulates outer-space cold conditions to evaluate brittleness and impact resistance of alloys and composites.
