Qualmark HALT Chamber Rentals Available Now

W5 Engineering provides flexible, reliable Qualmark HALT/HASS chamber rentals to support short-term testing spikes, urgent product launches, or capital budget constraints. We feature industry-standard Qualmark T3.0 (36" x 36" vibration table) and Qualmark T4.0 (48" x 48" vibration table) systems ready for fast deployment to your facility.

What it is

W5 Engineering rents the Espec and Qualmark T3.0 and T4.0 HALT/HASS systems on short-term and long-term terms, so you can run full combined-environment testing without a capital purchase. Both are dual-purpose HALT (Highly Accelerated Life Test) and HASS (Highly Accelerated Stress Screen) chambers. Each pairs an xLF2 six-degree-of-freedom repetitive-shock vibration table with a vacuum-jacketed liquid-nitrogen thermal system. The T3.0 carries a 36 × 36 in table for mid-sized and larger products and low-volume HASS. The T4.0 carries a 48 × 48 in table for HALT and HASS on large products.

• Two rental models — T3.0 with a 36 × 36 in (914 × 914 mm) table; T4.0 with a 48 × 48 in (1,219 × 1,219 mm) table
• Vibration — xLF2 six-degree-of-freedom repetitive-shock table with random, broadband excitation from 10 Hz to above 5,000 Hz
• Acceleration — 5 to 65 gRMS (T3.0) and 5 to 75 gRMS (T4.0), measured on a bare table
• Temperature range — −100 to +200 °C (−148 to +392 °F); optional high-temperature range to +250 °C (+482 °F) on the T4.0
• Thermal ramp rate — 70 °C/min (126 °F/min)
• Table capacity — 450 lb (204 kg) on the T3.0; 600 lb (272 kg) on the T4.0
• Adjustable interior — the vibration table mounts at two heights on both models

Why rent

• Short-term testing spikes — add HALT/HASS capacity for a program peak without adding a permanent asset.
• Urgent product launches — get a chamber in place when a design-verification schedule cannot wait for a capital purchase cycle.
• Capital budget constraints — run a HALT/HASS program from an operating budget.

What it is used for

Some of the use cases for the T3.0 and T4.0 rental systems include:

• HALT on mid-sized and larger products — finding design weaknesses fast by stepping vibration and thermal stress to operating and destruct limits
• Low-volume HASS — screening process-induced defects on the T3.0, which is designed specifically for this work
• HALT and HASS on large products — testing large assemblies and heavy fixturing on the T4.0's 48 × 48 in table
• Solder-joint and surface-mount screening — using the table's high-frequency energy to expose weak solder joints and SMT weaknesses
• Complex-assembly excitation — using low-frequency energy to penetrate complex products while delivering roll, pitch, and yaw around the X, Y, and Z axes

T3.0 or T4.0

Pick the T3.0 for low-volume HASS and for HALT on mid-sized to larger products. Its two table heights let you adjust interior volume to the product.

Pick the T4.0 for HALT and HASS on large products. It also suits test articles that need the high-temperature range or a table that can carry hundreds of pounds of product and fixturing.

Full workspace, dimension, electrical, and LN2 details are in the Specifications tab.

Key features

xLF2 table with PSD management. The field-maintainable Power Spectral Density table can be restored to factory PSD with a simple maintenance procedure, keeping results consistent at higher gRMS.

Consistent broadband spectrum. Random six-degree-of-freedom excitation from 10 Hz to above 5,000 Hz delivers a consistent PSD profile that eliminates picket fencing.

Rapid LN2 thermal system. Vacuum-jacketed liquid-nitrogen injection cooling and open-element nichrome heating, with turbulent airflow to maximize heat transfer to the product.

Two-position table. The table mounts at two heights, trading table-to-ceiling height for a tighter interior on smaller products.

Lubricant-free actuators. Ten on the T3.0 and 12 on the T4.0.

Lab and production control. PLC control with a desktop PC, monitor, and Typhoon Manager software. The T series Manager handles up to 12 thermal and four vibration channels, has three password-protected user levels, and offers a separate HASS screen for operators who only need to run profiles.

Quiet operation. The T4.0 delivers its thermal and vibration performance while running notably quietly.

Why engineers pick it

Real combined stress in one chamber. Six-degree-of-freedom repetitive-shock vibration and 70 °C/min thermal ramps are applied together, the combined environment HALT/HASS relies on to drive out latent failure modes that single-axis vibration or thermal-only methods miss.

Repeatable PSD over the rental term. The xLF2 table is field-maintainable back to factory PSD, so a profile run in week one matches a profile run months later.

Efficient on LN2. The T series airflow design reaches set points faster and uses far less LN2 through the dwell than traditional HALT/HASS systems. Espec rates the utility savings at 20 to 40% compared with previous generations.

Proven platform. Espec has deployed more than 1,500 Qualmark systems and performed over 5,500 HALT/HASS tests in its own labs.

Site readiness

A HALT/HASS rental needs three things in place before it runs: power, liquid nitrogen, and safe nitrogen handling.

• Power. Both models run on 380, 400, 440, or 480 V three-phase, 50/60 Hz. The T3.0 needs an 80 A service. The T4.0 needs 100 A, rising to 150 A (380/400/440 V) or 125 A (480 V) with the high-temperature option.
• LN2 supply. Qualmark systems require a 50 psi (3.4 bar) liquid-nitrogen supply. A vacuum-jacketed manifold is standard on both models. Vacuum-jacketed piping delivers smooth, consistent cold ramps without vapor slug flow.
• LN2 storage. Bulk tanks, microbulk tanks of roughly 450 to 2,000 L (119 to 528 US gal), or dewars. Dewars suit temporary setups. For the T3.0, a Qualmark dewar kit manifolds three or four dewars to the chamber.
• Elevation stand. Strongly recommended for the T3.0; it raises the system 11¾ in (298 mm) off the floor.
• Nitrogen safety. Air-purge and door-lock kits normalize oxygen before the doors release. An oxygen sensor and an LN2 emergency-stop system that closes the supply valve on alarm are also available.

Fixturing for repetitive-shock tables

Repetitive-shock fixtures are built differently from electrodynamic shaker fixtures. ED fixtures are heavy and rigid and mimic the product's in-use mounting. RS fixtures are light and flexible. Because the table vibrates in six degrees of freedom, mounting orientation does not matter. The goal is maximum vibration transmission without radically changing the frequency content. HASS fixtures add requirements for temperature response, consistent stress from location to location, and fast product changeover.

Qualmark HALT fixture kits in SAE or metric fit both the T3.0 and T4.0. Custom fixture development is available from pre-engineering through proof of screen.

Configuring your rental

Select the T3.0 or T4.0 in the model selector and use Request Quote to start your rental. Contact W5 Engineering for anything the selector does not cover: rental term, the T4.0 high-temperature option, table thread standard (metric M-10 or SAE 3/8–16 UNC), LN2 supply and storage, dewar kit, elevation stand, fixturing, and safety kits.
