Product catalog summary

Specifications:
The DW-30L818 is a large capacity biomedical freezer designed to operate at -30°C. It features an energy-efficient hydrocarbon (HC) refrigeration system with a high-efficiency HC compressor that reduces energy consumption. The freezer offers a large internal space with adjustable shelves for flexible configuration and maintains a uniform temperature throughout the cabinet with a built-in evaporator.

Performance and Design:
The freezer operates with low noise emissions, less than 44dB, and is environmentally friendly, using natural non-toxic HC refrigerants. It complies with European ROHS directives and environmental protection guidelines. The unit is suitable for use in blood banks, hospitals, research institutions, and other industries for preserving plasma, biological products, and conducting cryogenic tests.

Features:
The freezer includes an ergonomic handle design for easy access, built-in lock and padlock features, and is equipped with 4 multi-directional casters and 2 lockable feet for easy movement and stability. It has a microcomputer electronic thermostat with an LCD digital display for precise temperature control, and multiple alarm functions for safety and reliability.

Security and Storage:
The freezer offers superior thermal insulation with a 70mm thick insulation layer, double door seals, and three inner doors. It includes a security lock, optional chart recorder for temperature records, and portholes for independent temperature testing. Optional plastic ABS drawers and stainless steel shelves are available for customized storage solutions.

Technical Data:
The freezer has a net capacity of 818 liters (28.9 cu.ft) and operates within a temperature range of -10°C to -30°C. It features a microprocessor control system, manual defrost mode, and uses HC refrigerant. The unit is certified with CE and includes a standard RS485 port, with optional USB interface and temperature logger.

Dimensions:

Haier -30°C Biomedical Freezer DW-30L818 V1-1

Large Capacity -30°C Biomedical Freezer Typical Installation and Application For use in blood banks, hospitals, research institutions, electronics, chemical and other industries, for the preservation of plasma and biological products and cryogenic test of components and materials. Energy eﬃcient hydrocarbon (HC) refrigeration system Optimised refrigeration system, utilising high-eﬃciency HC compressor signiﬁcantly reduces energy consumption. Greener by design HC refrigerants are natural non-toxic and more environmentally friendly than HFC refrigerants. This alongside the HC compressor technology and LBA foamed polyurethane insulation layer, make this unit greener and in-line with European ROHS directives and environmental protection guidelines. Large capacity, superior uniformity Built-in evaporator for faster cooling speed and uniform temperature throughout the cabinet, ±3℃. Large internal space with adjustable shelves for ﬂexible conﬁguration. Low noise Optimised system and cabinet design ensures low noise emissions, less than 44dB. Biomedical Co.,Ltd.
