Precision in controlled environments
Labs & Cleanrooms
Labs and cleanrooms are regulated environments that need tight, repeatable leaving-air conditions. APR‑E Valve adds electronic discharge air control to standard DX equipment, holding conditions in compliance-critical spaces, while mechanical APR Control protects comfort equipment across the campus.

Why APR Control fits labs & cleanrooms
Repeatable conditions, without a full-system replacement.
- APR‑E Valve holds discharge air temperature to ±1°F on DAT control for stable controlled-space operation
- Continuous modulation replaces the on/off cycling that unsettles sensitive spaces
- Retrofit on existing DX equipment: no crane, no curb change
- 77% fewer compressor starts and zero failures since install in an independent field study
- Every application is sized through a complimentary Rawal Devices Engineering consultation
