Slimline Range / General Purpose

General purpose thermal and environmental chambers

A range of compact, easy-to-use chambers designed for general testing and process applications – ideal when the overall chamber size is important and product loading is relatively low.

Typical Applications

Process drying where temperature uniformity is essential, e.g., pharmaceuticals
Stabilising products prior to installation or more demanding testing
Temperature/humidity testing under fixed or cyclic conditions, satisfying numerous IEC 60068 test requirements plus a wide range of equivalent specifications

Advantages

Small Footprint & Easy to Move

Designed to have a small footprint while maintaining excellent performance, eg the Slimline 450 model has a 0.7m2 footprint. Large, lockable castors make moving the chambers very easy.

Good Circular Airflow

Air is drawn in to the centre of the rear wall, conditioned in the plenum before re-entering the chamber at the front through a grill by the door.

Ideal for General Purpose Testing

The Slimline range was designed to suit general purpose applications, such as small electronic modules, sub-assembly testing, etc. where good control at specific conditions is required.

Wide Temperature and Humidity Ranges

Temperature ranges of +180°C to either -40°C or -70°C are available and the Slimline range is renowned for is wide humidity conditions which exceed Area ‘A’ – the norm for most chambers in this category.

Capacitive Humidity Probe

All Slimline humidity chambers are fitted with a high-quality, no-maintenance capacitive humidity probe, for hassle free humidity testing.

Suitable for a large range of Test Standards

Slimline chambers are used by a wide range of industries, from Oil & Gas to Aerospace and Pharmaceutical, to achieve their specific Test Standards, as well as International Standards such as IEC60068 (Environmental Testing of Electrotechnical Products).

Suitable for a large range of Test Standards

Custom versions available

As well as the standard range of Slimline chambers, our inhouse design and manufacturing in the UK, means we have produced many custom versions of the Slimline range including Fast Shock (Oil & Gas), Humidity Drying (Pharmaceutical) and many more…

*Measured after stabilisation (IEC 60068-3-5)

Slimline Thermal Chambers

Choose from three different cooling mechanisms depending on your requirements.

Compressor Cooling

Refrigerant gases in a closed-loop system are repeatedly compressed and expanded to cool the air in the chamber (same principle as domestic refrigerators)
Maximum temperature = +180°C; minimum temperature = -40°C (single-stage compression) or -70°C (multi-stage or cascade compression)
Temperature ramp rate = 1-2°C/min (standard); high-performance models achieve better than 3°C/min
Offers reliable continuous operation with no ancillary services required
Ideal for testing electronic assemblies with low heat dissipation

Indirect Liquid Nitrogen (LN2) Cooling

Liquid nitrogen used as a refrigerant to indirectly cool the air in the chamber (nitrogen gas is then vented to atmosphere)
Safer than direct LN2 injection – normal levels of oxygen are always maintained inside the chamber
Maximum temperature = +250°C (standard models +200°C); minimum temperature = -70°C
Temperature ramp rate = 10°C/min
Requires continuous supply of LN2 and safe venting of nitrogen gas during operation
Can cope with greater heat output from components under test than compressor cooling
Ideal for thermal stressing and accelerated life testing

Forced Ambient Air Cooling

Range of heat-only chambers (ovens) with same dimensions and volumes as ranges above (model numbering TC Slimline 300 FAC, etc)
Controlled cooling to avoid thermal shocking of components under test
Maximum temperature = +250°C; minimum temperature = ambient + 20°C

Slimline Environmental Chambers

Combine temperature cycling with precise control of the relative humidity.

Same cooling mechanism as compressor-cooled thermal chambers
Maximum temperature = +180°C; minimum temperatures = -40°C (single-stage compression) or -70°C (multi-stage or cascade compression)
Water vapour added to air from heated water bath and removed through condensation on cooled copper coil
Relative humidity = 10-96% over temperature range of 10-100°C (Area ‘A’ in chart)

Humidity – Standard Operating Regions

A – Typical region of humidity control in chambers
B / C – Optional regions for specialised applications
