Product catalog summary
Overview: The document provides detailed information about ESPEC's Constant Climate Cabinets, specifically models LH, LHL, LHU, and LU. These cabinets are designed for temperature and humidity testing in laboratories and research facilities, offering high performance and reliability.
Specifications: The cabinets come in six models with capacities of 105 and 206 liters, supporting a wide range of temperature (from -20℃ to +85℃) and humidity (40% to 95% rh) conditions. They operate on a single-phase power supply and feature a PID control system for precise temperature and humidity management.
Key Features:
  • Stable internal environment with temperature/humidity uniformity of ±2℃ and ±6% rh.
  • Program operation allows up to 9 steps per pattern with ramp time specification.
  • Safety features include an upper deviation limit temperature alarm, ground leakage breaker, and overheat protector.
  • Patented cross-output control system in the LHU-123 model reduces power requirements.
Performance: The cabinets are equipped with a mechanical refrigeration system and hermetically sealed compressors. They offer a balanced temperature and humidity control system, with specific models capable of reaching low temperatures of -20℃.
Utility Requirements: The cabinets require an ambient temperature of 0 to +40℃ and are compatible with various power supply specifications (100V, 115V, 220V, 230V AC).
Accessories and Options: Standard accessories include shelves, water supply/drainage hose, and a user manual. Optional features include additional cable ports, inner doors, and various communication interfaces (RS-485, GPIB, RS-232C).
Safety Devices: The cabinets are equipped with multiple safety devices such as a leakage breaker, boil dry protector, thermal fuse, and refrigerator overload relay to ensure safe operation.
Conclusion: ESPEC's Constant Climate Cabinets are versatile and reliable solutions for environmental testing, offering advanced features and safety mechanisms to meet diverse laboratory needs.
