Espec Qualmark Typhoon HALT Chambers

Espec Qualmark Typhoon HALT Chambers combine extreme temperature cycling and repetitive shock/vibration for the ultimate in accelerated reliability testing. The Typhoon's HALT technology has matured from a simple thermal shock chamber with a vibration table and independent controls to an integrated HALT/HASS system. Espec Qualmark Typhoon HALT chambers have consistently been the market leader since introducing the technology in the early 1990s. Today, Espec's technology continues to reflect the best advances in HALT/HASS testing. The Omni-Axial six-degree-of-freedom, random, broadband excitation (10 Hz to above 5,000Hz) delivers a consistent power spectral density profile that eliminates "picket fencing." The thermal system features vacuum-jacketed liquid nitrogen cooling and nichrome wire heating, resulting in ramp rates of 60-100˚C per minute.

The Espec Qualmark Typhoon Series is composed of the following models: the Typhoon 2.0, Typhoon 2.5+ Inferno and the Typhoon 3.0.

Cooling System
- Simultaneous excitation at multiple frequencies for testing complex assemblies
- Patented pneumatic hammer/table design is lubrication-free and valve-less
- Quiet operation and no external cooling required
- Standard 75 gRMS performance; up to 100 gRMS available
- Table is field-adjustable for resetting to original PSD levels, ensuring consistent performance. (Adjustment included in our preventative maintenance agreement)
- Vacuum Jacketed (VJ) liquid nitrogen (LN2) valves and manifold. (VJ manifold optional on T1.5/2.0 models)
- Proportional control and valve system for maximum LN2 efficiency and consistent temperature control, while reducing two-phase (gas/liquid) states that cause problems in traditional on/off solenoid-based control
- VJ eliminates condensation, dripping water, OSHA safety concerns, and energy loss compared to other insulation methods
- Efficient, economical LN2 usage with either low-pressure Dewar tanks or higher pressure Permacyl and LN2 bulk tank systems
Chamber Design
- Stainless steel interior, painted exterior with two full opening doors (one door on T1.5/2.0 models)
- High-velocity airflow for improved product temperature change rates
- Two-position table for flexibility to test taller samples, improved ergonomics, and less LN2/electricity usage for smaller test items (except T1.5/2.0)
- Advanced chamber insulation combined with our low-noise hammers results in very quiet operation, even at maximum vibration levels
- Adjustable feet for leveling unit (stand options for T2.5/3.0 models)
Control System
- Windows 10 system with Labview based operation and PLC-based controls
- Programming, operation, and datalogging for vibration/thermal profiles
- One accelerometer for table control (three additional inputs available)
- Two thermocouples: one for product, one for air (four additional inputs available)
- Eight event relays for external controls
- Optional Q-Link or Qualview software tools for ATE integration and other remote connections
- Optional integrated spectrum analyzers and data acquisition systems
