Compact Thermal Shock Chambers

Provides Superior Performance in a Small Footprint

VTS Compact Thermal Shock Chambers consist of two separately controlled hot and cold zones with product being transferred between these zones for rapid product temperature changes. These thermal shock chambers are available with 1 or 3 cu. ft. (30 or 85 liters) of interior workspace volume, ideal for testing to find product flaws in small components/assemblies before they reach your customer.

Superior performance and small footprint coupled with many standard features provide exceptional value. The lower chamber also contains both heating/cooling and may be programmed and operated as a separate temperature cycling chamber for greater return on investment.


Our VTS-1 thermal shock chambers are also available from stock

Touch Screen Controller
  • CSZ EZT-570 Touch Screen Controller is designed to save chamber programming and setup time. Standard features data logging, data file access via memory stick or PC, Ethernet control and monitoring, alarm notification via email or phone text message, full system security, online help & voice assistance in multiple languages and more.
  • A Temperature Limit and alarm is included to protect your product.
EZ-View Software
  • RS-232/485 serial communications, Ethernet control and monitoring offer a selection of communications options.
  • EZ-View optional software allows user to control and monitor up to 20 chambers from any location.
Compact Thermal Shock Basket
  • Rapid airflow through the workspace. This is the cornerstone to successful performance of MIL-STD 883G, Method 1010.8 (Test Condition C) and for Environmental Stress Screening. Provides an average of 500 feet per minute air velocity over the devices under test to facilitate fast part temperature change rates
  • Utilizes electric actuator for lift mechanism for smooth product transfer less than 5 seconds. No special utilities such as air are needed.
  • Travelling Cable port for powering up device under test.
  • Removable panels provide easy access to all systems for maintenance purposes.
  • Door safety feature prevents the transfer basket from moving when door is opened.
  • All liners are constructed from Type 304 brushed stainless steel that is easy to clean. All seams are continuously welded to form a hermetically sealed unit to prevent moisture migration.
  • The chamber exterior is constructed of formed sheet steel for structural strength and finished with a durable powder coat finish or textured polyurethane paint.
VTS Test Chamber
  • Pressure gauges allow operating pressures to be continuously monitored and provide early warning indicators.
  • CSZ test chambers utilize refrigerants which are environmentally safe, non-flammable, non-explosive and have a Zero Ozone Depletion Potential (ODP).
  • High volume airflow system includes robust air circulator motors that provide better airflow and improves controllability within the chamber. Better airflow minimizes temperature gradients and accelerates temperature change rates of the device under test.
