CTS Thermal Shock test machines − energy optimisation option.

Experienced users of Thermal Shock Test Chambers will be familiar with the power consumption required to run a full size (typically 130 litre test space) machine for long term testing. Many labs monitor machine power use and managers often struggle to reduce power bills.

All CTS Thermal Shock Chambers now have systems designed to allow power optimisation when running tests.

Two chamber thermal shock machines until now have mainly kept power supplied to both upper (hot) and lower (cold) test spaces whilst testing, however the product may dwell in each of the chambers for long periods. During this dwell the power to the other test space is wasted.
The CTS control system allows the power consumption to the unoccupied part to the machine to be moderated or turned off when test profiles allow. 

Benefits include:
  • Lower energy costs.
  • Less heat dissipated to the lab or through the chilled water system.
  • Less noise.
  • Overall a contribution to site energy efficiency.

Example:
With an assumed operation time of 6000 hours per year (using a Typical TSS-70/130 chamber).

Without CTS optimised control system:           
approx. 34,800 kWh.
At identical operation with optimised control system:    approx. 23,100 kWh.

Saving in energy consumption:               
approx. 11,700 kWh.

06/10/2015 - EMC testing adapted CTS environmental chambers available. Engineers previously needed to expose their products for environmental temperature and humidity conditions then arrange for separate EMC testing in a suitable large chamber.
06/10/2015 - Controlling CTS Environmental Test Chambers. Engineers often ask these common questions:
06/10/2015 - Why we use capacitive sensors for humidity measurement and control Ten reasons CTS chambers use capacitive sensors instead of pychrometric (wet sock) sensors for humidity measurements and control.
03/9/2014 - CTS Thermal Shock test machines − long term testing icing resistant design feature. Experienced users of Thermal Shock Test Chambers will be familiar with the issue of ice build-up which can impede long duration testing programs.
