Custom capacities and chiller performance options available on enquiry.
Precision Thermal Shock Testing with Dedicated Chiller Support
The NPD Vertical Thermal Shock Chamber uses independently controlled hot and cold zones and a vertical basket-transfer mechanism to expose specimens to sudden temperature changes. The arrangement supports the change-of-temperature testing approach described in IEC 60068-2-14 Test N.
The integrated chiller plant delivers 52.75 kW (15 TR / 45,000 kcal/hr) of cooling capacity and 15°C chilled water, providing cooling support for repeated high-load thermal cycles. A 32-bit PLC/HMI controller, cascade refrigeration system and forced-air circulation support repeatable laboratory and industrial testing.

How the System Works
A repeatable thermal shock sequence supported by dedicated cooling.
Set Test Profile
Use the 7-inch HMI to configure chamber profiles, temperature targets and programme cycles.
Pre-condition Zones
Independently condition the hot and cold zones before specimen transfer.
Vertical Basket Transfer
Move specimens between hot and cold chambers to impose rapid temperature transitions.
Monitor & Record
Track temperatures and alarms, review trends and export logged test information.
Controller, Programming & Operating Modes
The 32-bit PLC/HMI platform provides PID auto-tuning, password-protected user access, configurable diagnostic views, real-time trends and temperature graphs. USB export supports transfer of test logs, programmes and reports, while Ethernet supports external connectivity.

Construction, Airflow & Optional Humidity Control
The chamber features a heavy-gauge stainless-steel interior and a powder-coated, double-walled cold-rolled steel outer body on an angle-iron frame. Heavy-duty castors with front wheel locks assist installation and movement. The chamber incorporates a left-hinged door, multi-pane toughened-glass inspection window, adjustable perforated stainless-steel shelves, double silicone door gaskets and toggle latches.
Forced air passes over heaters in the hot zone and heat exchangers in the cold zone, supporting consistent temperature conditioning. Optional refrigeration-based dehumidification can support condensation-sensitive tests. The described humidity system includes an SS 304 steam-generation boat, heaters and humidity circulation.
