Description
Hirayama PC-R8D Dual HAST Chamber — Two Independent Test Vessels
The Hirayama PC-R8D dual HAST chamber is the two-vessel configuration of the PC-R8 series, distributed in North America by Hastest Solutions. The PC-R8D houses two completely independent HAST test chambers — each with its own steam generator, controller, and exhaust system — within a single floor footprint. This doubles parallel throughput for high-volume semiconductor package qualification, automotive electronics validation, and reliability testing labs without doubling floor space.
Available in two configurations: PC-304R8D (34.5 L per chamber) and PC-422R8D (84.4 L per chamber). Each chamber operates independently, so two different test conditions, programs, or specimen sets can run simultaneously.

When to Choose Dual over Single-Vessel
The PC-R8D is the right choice when:
- Your lab runs continuous high-throughput qualification and a single chamber creates a bottleneck
- You need to compare two specimen lots under identical environmental controls in parallel
- You want redundancy — if one vessel needs maintenance, the other continues operating
- Floor space is at a premium and a two-chamber footprint is worth the cost premium
For single-chamber needs at lower capital cost, see the PC-R8 single-vessel HAST chamber.
Same Hirayama Engineering Standards as PC-R8
The PC-R8D inherits all PC-R8 engineering features: dual-vessel structure within each test chamber, color touch panel, two control methods (unsaturated HUM and saturated STD), three exhaust modes, electrolytic-polished SUS316L stainless steel construction, electric clamp door locking, slide-out sample tray, and RS-232C communication for centralized control of up to 16 chambers via HAST-NET software. The PC-R8D meets IEC 60068-2-66, JIS C 60068-2-66, and is suitable for JEDEC JESD22-A110 reliability qualification.

Frequently Asked Questions
Can the two chambers in PC-R8D run different test conditions simultaneously?
Yes. Each chamber has its own controller, steam generator, and exhaust system, allowing fully independent test conditions, durations, and programs.
Does PC-R8D require twice the utility connections?
The PC-R8D requires two power supply cords (one per chamber) but shares a single drainage system. Power requirement is approximately 2.5 kW per chamber for PC-304R8D, 3.2 kW per chamber for PC-422R8D.
What is the difference between PC-R8D and PC-R9D?
The PC-R9D is the next-generation dual chamber with USB data recording, remote operation software, automatic cleaning mode, CE Marking, and China SELO approval. PC-R8D shares identical chamber capacity, temperature/humidity/pressure ranges, and IEC 60068-2-66 compliance at a more economical price point.
