Thermostatic test chamber PCT series

climaticpressurehigh-pressure

Product Overview
Pressure Cooker Test Chamber PCT Series (PCT-25, PCT-35, PCT-45) provides a controlled environment of high temperature, high humidity and pressure using 100% RH saturated steam to assess the physical and sealing properties of electrical/electronic products, components, metal and magnetic materials. It is intended to verify product performance, support design improvements, validation and incoming/outgoing inspection.

Application

• Sealing tests for multilayer circuit boards and IC package seals.
• Environmental and aging tests for LCD panels, LEDs and semiconductor devices.
• Pressure and airtightness evaluation for magnetic materials (NdFeB, rare earths, magnetic iron) and related parts.

Product Parameters

• Model: PCT-25 / PCT-35 / PCT-45.
• Internal dimension (Φ×D, mm): 300×250 / 350×450 / 450×550.
• External dimension (approx., mm): 750×1200×800 / 800×1250×800 / 900×1380×900.
• Temperature range (saturated steam): typically 100°C ~ 135°C. Example setpoints: 120°C (100 kPa) / 133°C (200 kPa). Higher temperature (e.g., 143°C) available by special order.
• Relative / Absolute pressure: gauge shows relative pressure; absolute pressure equals gauge reading plus 100 kPa (actual internal pressure).
• Humidity: 100% RH (saturated steam).
• Steam pressure (absolute): 101.3 kPa +0.0 Kg/cm2 ~ 2.0 Kg/cm2 (3.0 Kg/cm2 special order).
• Circulation: steam natural convection circulation.
• Safety protections: water short-storage protection, overpressure protection, automatic/manual water replenishment, automatic pressure discharge.
• Accessories: two-layer stainless steel plate.
• Equipment capacity (L): 17 / 43 / 87.
• Power supply: AC 220V (±10%), single phase / three-line, 50/60 Hz.

Safety devices

• Lid interlock: machine will not start if inner chamber is not closed.
• Safety valve: automatic pressure relief when internal pressure exceeds rated value.
• Double overheat protection: alarm and automatic heating cut-off on over-temperature.
• Cover protection: inner lid made of aluminum alloy to protect operators from scalding.

Features

• Automatic water replenishment when water level is low during tests.
• Automated test procedures for unattended operation.
• LED digital temperature controller for accurate setting, control and display.
• LED digital timer to ensure tests run for the programmed duration after reaching set temperature.
• Accurate pressure–temperature chart displaying internal pressure and relative humidity.
• Automatic discharge of non-saturated steam to ensure optimal steam quality.
• Integrated silica-gel door gasket for excellent airtightness and long service life.
• Mirror-polished inner chamber: durable and non-contaminating.

Package
Packaged with PP film and 10 mm foam between machine and case; outer packaging meets standard export requirements.
