Environmental test chamber

Environmental Chambers We offer an extensive range of Environmental Chambers for testing at non-ambient temperatures. The ETC Series environmental chambers are compatible with both static and dynamic test systems and available with temperature ranges between -150°C to 600°C. Standardised designs are available to suit both single column or twin column table- top frames or floor standing twin or four column test systems. This Series use liquid Nitrogen cooling (CO2 cooling on request) and utilise forced air recirculation. Construction The inner chamber is constructed from 316 stainless steel and insulated by high efficiency insulation. This durable stainless steel interioreliminates the risk of high temperature oxidation. A forced air skin heating/cooling system is incorporated to minimise skin temperatures when testing at high temperature. The outer case is constructed from mild steel with a durable grey finish. Principle of Operation The ETC Series of environmental chambers use forced air recirculation to promote optimum temperature uniformity with reduced thermal gradients in the region of the test specimen. Using a fan system that circulate hot or cold air around the specimen, grips and grip extensions to provide programmable heating & cooling rates and good thermal stability. The air is forced (forced convection) over a set of heating elements and enters the insulated test enclosure at top and bottom. This heated air is drawn back into the centre of the fan through a 'baffle plate' and is recirculated.
