Defrost Laboratory Freezers

General Purpose Solid Door Manual Defrost Freezer

The Standard Manual Defrost Freezers are intended for general purpose applications where precise temperature control and maintenance are not essential and there are no requirements for temperature alarms. Manual defrost units have been designed to operate without product damaging auto defrost cycles. 

The NSPF units have natural refrigerants.  he Hydrocarbon Manual Defrost Freezers take a large step forward in performance from past solid door general purpose units; offering a digital temperature display and alarm module coupled with a microprocessor temperature controller.

Defrosting of the unit will need to be performed periodically to prevent severe ice build-up.

Nor-Lake Scientific is Going Green!  We are an industry leader in providing a variety of Refrigerators and Freezers that are built with Hydrocarbon Refrigerants, R290 or R600a.

Environmentally friendly, natural hydrocarbon (HC) refrigerants (not containing hydrofluorocarbons) vastly reduce global-warming potential (GWP) while meeting new EPA/SNAP mandates and UL, ASHRAE compliance guidelines.

Periodic manual defrost is required on these units.

Haier -25°C Biomedical Freezers

  • Hydrocarbon (HC) Energy-saving - Both units adopt an efficient hydrocarbon (HC) compressor and optimized refrigeration system. The DW-25L262 has a power consumption as low as 0.95KW·h/24h. The DW-25L92 has a power consumption of just 0.65KW·h/24h.
  • Environmentally Friendly - The HC system is a completely green refrigeration solution. With LBA foamed polyurethane insulation in line with European ROHS directive for environmentally friendly materials.
  • Low Noise - Optimized hydrocarbon system and structural noise reduction design, DW-25L262 noise 34 dB, super quiet and low noise. The DW-25L92 noise is 27 dB.
  • Security Lock - Mechanical lock plus lock catch, the mechanical door lock can be opened with one key, and the door lock can be padlocked. Secure and safe, suitable for multiple users

Haier -30°C Biomedical Freezers 

High-efficiency and energy-saving compressor and system

  • Industrial grade energy-saving compressor and optimized cooling system reduce more than 55% power consumption to achieve -30 °C compared with older models.

Green and Environmentally Friendly

  • Hydrocarbon refrigerant compressor, hydrocarbon refrigerant, completely green and environ mental friendly refrigeration system; Built with isopentane foam polyurethane insulation, the series complies with European RoHS Directive, green and environmental protection/friendly.

Low Sound Level

  • Sound-reducing design with optimized system and structures reduces the sound level, smoother operation eliminates high-pitched noise.

Superior Temperature Uniformity

  • Evaporator-shelf design produces a faster cooling process and a more uniform temperature distribution. The temperature uniformity at characteristic points is ±4 °C.

Key Features

  • Microprocessor temperature controller
    • Adjustable temperature setting from -10°C to -30°C
    • Multiple alarm functions
    • Sound and flash alarm
    • Alarm lasts for more than 24 hours after power failure
  • High efficient insulation and double-sealing  design improves temperature performance, energy efficiency, and system reliability
  • Lock latch and key lock double-lock design provides an extra level of security
  • Porthole design is standard for test
  • Optional chart temperature recorder available
  • Biomedical and life science laboratories within blood banks, hospitals, disease control centers, research institutes,  as well as electronics and chemical industries. Used for cryopreservation of plasma, biologics and other products and cold tests for components and materials.
