Description

Main features of ULT chest freezer

  • Dual-stage refrigeration system for sustained ultra-low temperatures
  • Hydrocarbon (HC) refrigerant with simplified maintenance options
  • Interior constructed in SS304 stainless steel
  • VIP (vacuum insulated panel) insulation for superior thermal retention
  • Touch-screen operation for intuitive control
  • Chest-type capacity up to 730 L (model dependent)
  • CO2 standby system option to maintain cooling during power interruptions


Temperature control system

  • Microcomputer controller with large digital temperature display
  • Precise temperature and alarm setpoint configuration
  • Electronic control capable of maintaining long-term −80°C (well below ice nucleation point) for reliable sample storage
  • Adjustable temperature range: −40°C to −86°C
  • Operation panel lock and password protection to prevent unauthorized changes
  • Optional 7" color LCD touch-screen display


Security measures

  • High-quality VIP vacuum insulation ensures strong thermal performance
  • Configurable high- and low-temperature alarms
  • Multiple fault diagnostics: sensor error, power failure, low battery, high ambient temperature, poor condenser dissipation, etc.
  • Three alarm modes: audible buzzer, visual flashing, remote alarm interface
  • Protection features including delayed restart and shutdown intervals
  • Optional CO2 backup refrigeration for emergency conditions


Cooling system

  • Imported brand compressors selected for ULT performance
  • High-efficiency hydrocarbon mixed refrigerants for rapid pull-down
  • Vacuum insulation panels combined with thickened eco-friendly ultra-microcellular foam for exceptional temperature stability
  • Patented cabinet sealing to retain cooling capacity and reduce energy loss
  • Imported ultra-low-temperature oil separator to protect system reliability
  • Optimized evaporative-condensing arrangement for strong cooling and low energy consumption


Ergonomic design

  • Patented ultra-light exterior handle operable with one hand; provisions for multiple padlocks
  • Double inner door design to reduce cold loss and permit separate zones
  • Compatible with international 2" and 3" standard freezing boxes
  • Heavy-duty lockable casters for mobility and positioning
  • Door-frame heating to prevent frost buildup around seals
  • Simplified condenser filter design for easy maintenance and cleaning
  • Includes air-pressure balance valve and temperature test port inside/outside the cabinet
