New range of high-efficiency thermal shock chambers

The innovative TSB range reduces the problem of continual loss of expensive testing fluids by several methods. One is enhanced airtightness, preventing the leakage of evaporated thermal fluid from the test area. Another is a fan that draws air to a condensing coil that turns evaporated fluid into a liquid, enabling it to be returned to the baths. A refrigerated cooling ring at the top of the hot bath helps to limit evaporative losses. All units incorporate a separation filter for removing water from the thermal fluid.

A new ozone-friendly HFC refrigeration circuit also reduces energy consumption, saves space and reduces weight. Improvements in the refrigeration design have reduced power consumption by 52 per cent, and noise levels to as low as 61 dB. The refrigeration change also reduces the chamber footprints by more than 15 per cent.

The SCP-220TS touchscreen programmable controller comes with an intuitive interface that makes programming and test monitoring simple. Expanded interface options allow chamber communication and control from an external PC.

Liquid-to-liquid thermal shock testing is typically conducted to apply very strong, repetitive thermal stress to test pieces. It can model a product's ability to withstand thermally induced size changes, crack resistance, hermetic integrity, and changes in electrical properties. This form of testing provides a very rapid temperature shock recovery of conditions, and can significantly reduce testing time by requiring shorter soaks and fewer cycles.

These high-quality chambers complement Unitemp's extensive range of test and monitoring chambers/ovens, and Unitemp has the expertise to provide 'specials' to customers requirements.

This versatile range has applications in the engineering, electronics, laboratory, process and manufacturing industries.
