Rapid thermal shock chamber F-TH series

for rapid temperature cyclinglow-temperaturelarge

Overview
Rapid Temperature Change Test Chamber (F-TH series) designed to apply high thermal stress to specimens by fast temperature ramps. Faster change rates (from 5 °C/min and above) are achievable with enhanced refrigeration; dual refrigeration loop enables rapid performance across wide ranges. Instrumentation is integrated in the door and the controller uses a color LCD touch-screen for straightforward operation.

Product headline / key model info
F-TH-150 / F-TH-225 / F-TH-408 / F-TH-800 (options A~F) — Rapid linear ramps 3–20 °C/min (linear), nonlinear peaks to 30 °C/min; optional humidity control 20%–98% R.H. (extended ranges with dehumidifier).

Control Modes

• Linear Mode — 3–20 °C/min with full linear control: adjustable ramp, constant slope, repeatable for qualification and audits.
• Nonlinear Mode — 3–30 °C/min with faster peak ramp: variable ramp rate across profile for accelerated stress screening (HALT-style); humidity function can be combined.

Features & Capabilities

• Ramp speed: up to 20 °C/min linear; nonlinear peak up to 30 °C/min.
• Temperature coverage with optional humidity: standard 20%–98% R.H.; 10%–98% or 5%–98% available with dehumidifier.
• Control accuracy and resolution: ±0.5 °C / ±2.5% R.H.; indication resolution 0.1 °C / 0.1% R.H.
• Four standard internal volumes (150 L, 225 L, 408 L, 800 L) with configurable A~F option levels.
• Integrated functions: BTHC temperature & humidity control (P.I.D. + S.S.R.), programmable multi-segment cycling (100 programs × 100 segments), power-off memory (5-year backup), imported color LCD touch controller, dual refrigeration loop, DIN PT-100Ω sensor, RS-232/RS-485 communication, interface lock and alarms.
• Protection devices: fuse-free switch, compressor overload protection, high/low pressure coolant protection, over-humidity and over-temperature protection, fault warning and water shortage alerts.
