Qualmark Typhoon 8.0 HALT Chamber (LN2)
The Qualmark Typhoon 8.0 doubles the width of our popular Typhoon 4.0 chamber. The thermal system in the Typhoon series has been carefully engineered to have superior thermal efficiency. Key design elements such as our patented blower technology, highly efficient air flow characteristics and careful choice of materials have combined to keep liquid nitrogen and electricity costs down without compromising our industry standard thermal performance.
The Qualmark Typhoon 8.0 has the largest vibration table available in a HALT/HASS chamber.
6DOF repetitive-shock table
Simultaneous excitation at multiple frequencies for testing complex assemblies
Patented pneumatic hammer/table design is lubrication-free and valveless
Quiet operation without external cooling requirements
The table is field-adjustable for resetting to original PSD levels, ensuring consistent performance. (Adjustment included in our preventative maintenance agreement.)
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
Microsoft Windows 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.
Liquid Nitrogen Vacuum Jacketed Piping
We work with your facilities teams to specify, design and supply the pipework for your HALT chamber.
Keep-full devices are essential to ensure optimum control of the chamber - preventing gas from creating PID disturbances.
Our pipe is made in the USA by Midwest Cryogenics and is simple to install and maintain.
Exhausts, airlines, and all other chamber utility requirements can be supplied.
External control and safety valves can be fitted to shut off supply in the event of a leak.
Safety Systems
We understand the risks of Liquid Nitrogen and have decades of experience planning installations and the safety mitigations that go with them.
Control panels inside the room are tied to gas detectors which can automatically shut the chamber supply line down at the source.
Control valves can be placed at key points along the route to ensure sections can be isolated through key facilities.
Additionally the control panels can be tied to facility supply and exhaust systems to increase air flow before critical alarms kick in and take the building down.
