Environmental & Laboratory Test Chambers

ETS has been providing service, maintenance and calibration for environmental and laboratory test chambers since 1983. We support all makes and models, helping organisations maintain performance, reliability and compliance.

From our Nazeing workshop, we carry out refurbishment of climatic chambers across a wide range of manufacturers. This enables clients to extend equipment life while restoring operational integrity and control accuracy.

Delivering this level of support requires broad technical expertise. Our team combines the necessary electrical, refrigeration, control and mechanical disciplines to ensure work is completed to a consistently high standard.
