*Rise and pull-down rates calculated using IEC 60068-3-5 standard. Custom options available.
*Ideal ambient temperature conditions for test chambers is 23°C (73.4°F). The temperature and humidity range of assured performance is between 15°C and 25°C (59°F/77°F) and 30-50% relative humidity. Conditions outside this range may affect the performance of your test chamber and reduce the lifespan of the equipment.
Notice for Customers Requesting R449A:
Consult our sales team regarding the use of R449A refrigerant (where applicable). This substitution ensures compliance with relevant regulations. Please be aware that the use of R449A will change the achievable low temperature to -35°C. Our sales team can provide detailed information regarding this change for your specific application.

Applications
APPLICATIONS & USE CASES
The WR Walk-In Series is highly customizable, depending on the product you are testing. Engineered as large-scale environmental rooms for full-size assemblies, server racks, satellites, and production-scale payloads, the WR Series is offered as both stability walk-ins (steady-state, long-duration conditioning) and performance walk-ins (iterative thermal cycling). Dimensions, door configurations, live-load capacity, floor loading, temperature and humidity ranges, ramp rates, pass-through ports, and controls are all tailored to the application.
