Thermal Test Laboratory Services

The TTi Thermal Test Laboratory provides production-grade environmental testing services using
TotalTemp Technologies thermal platforms.

Our focus is on repeatable, well-documented thermal and thermal vacuum (TVAC) testing for
engineering development, qualification, and small-batch screening.

TTi operates a controlled thermal test laboratory configured around modern thermal chambers,
precision controllers, and automated data acquisition. Customers may submit units under test (UUTs) for:

• Thermal cycling across defined temperature ranges
• Thermal soak / dwell at fixed setpoints
• Thermal vacuum (TVAC) small tests for space-relevant environments
• Custom profiles with controlled ramps, dwells, and monitoring

Each test campaign is executed under a written procedure, with traceable configuration records,
calibrated instrumentation, and structured reporting suitable for engineering and compliance documentation.

• Temperature range: application-dependent, typically from sub-ambient to elevated temperatures
• Control hardware: TotalTemp Technologies chambers with Synergy-class controllers
• Monitoring: multi-channel thermocouples, chamber sensors, optional external instrumentation
• Automation: programmable profiles, data logging, time-stamped event records
• Documentation: test plan, run logs, summary report, data exports

TTi offers thermal testing as a service for customers who do not wish to own or operate chambers directly.
Typical engagements include:

• Engineering development runs to evaluate prototypes under thermal stress
• Qualification campaigns aligned to customer specifications or industry standards
• Small-lot screening of production units prior to shipment

For each project, TTi collaborates with the customer to define:

• Test objectives and acceptance criteria
• Thermal profile (ramps, dwells, cycle count)
• Instrumentation layout and measurement points
• Handling and fixturing requirements for the UUT

TTi’s Thermal Vacuum (TVAC) small test service is intended for components and assemblies that
require exposure to combined temperature and reduced-pressure environments representative of
high-altitude or space applications.

1. Definition of environment: temperature range, vacuum level, dwell times, cycle count.
2. Fixture and interface review: mounting, electrical connections, outgassing constraints.
3. Chamber configuration: TVAC setup, leak check, instrumentation verification, profile loading.
4. Test execution: pump-down, thermal ramps, dwells, continuous monitoring.
5. Data and reporting: time-series data, event logs, final test summary.

TVAC small tests are scoped for components and subassemblies within the physical and thermal limits
of the available chambers. Larger or higher-risk articles may require separate review.

• Approved test plan and configuration summary
• Run logs including profile execution and notable events
• Data files (temperature, pressure, monitored parameters)
• Final test report with conditions, observations, pass/fail assessment

Prospective customers may submit a brief description of their UUT, desired thermal or TVAC
conditions, and schedule constraints. TTi will respond with a proposed test approach, estimated
laboratory time, and a service quotation.

Formal work begins upon acceptance of the proposal and receipt of test articles.
