Air-Conditioning Units (ACU)
Slimline-ACU and Typhoons
ACUs suitable for a wide range of applications. Slimline-ACU range – compressor cooled ACUs for general purpose applications – small footprint.
More powerful LN2 version maintains small footprint but is suitable for more demanding applications. For High Performance requirements, the Typhoon range is designed to exceed the toughest specifications.
ACUs are normally connected to custom insulated enclosures via insulate hoses but Sharetree also offers our proprietary “Direct Connect” solution for improved performance (see brochure).
Typical Applications
- Test Setups unsuitable for standard chambers
- Thermal Stress
- Aerospace sub-assembly testing
- Temperature cycling
- Oil & Gas – Low magnetic interference testing
Advantages
Flexible
ACUs offer the advantage that they can be used to condition different enclosures. This ensures some level of future proofing as new enclosures can be designed to suit new needs, while still using the existing ACU.
High Airflow
Our ACUs are normally fitted with backwards curved impellers that provide good resilience to the back pressure encountered in hoses, ensuring high volumes of air at the enclosure
Wide Temperature Range Optional Humidity
Temperature ranges of +180°C to either -40°C or -70°C are available. Liquid Nitrogen (LN2) cooled ACUs can extend this to +250°C to -80°C. Mechanically cooled ACUs can also be fitted with Humidity control to Area ‘A’ (the norm for most chambers in this category).
High Temperature +250°C versions
The Typhoon ACUs with mechanical cooling, can also be supplied in a High Temperature version (+250°C) using our Evaporation Protection System.
Proprietary “Direct Connect”
The Slimline-ACUs are available with large rectangular inlet and outlet ports for direct connection to an enclosure, where suitable. This offers better airflow than hoses.
Proprietary “Ice Protection”
The Typhoon-ACUs can be fitted with an “Ice Protection” system. This was developed for the Aerospace industry to allow water spray to be used in the enclosure to build up ice on products under test. The ACU can protect itself against the water/ice coming back into the evaporator.
Custom Enclosure Design
In addition to providing standard and custom ACUs, Sharetree can also combined them with Custom Enclosures. See Custom Enclosures on our website for details.

Air Conditioning Units
Sharetree Air Conditioning Units (ACUs) are specifically designed for recirculating conditioned air through a variety of custom built product enclosures, or directly to products. ACUs are used where a standard test chamber cannot easily be fitted around the product. Custom designed product enclosures can also be supplied, if required. Remote sensing ensures good thermal control of the test enclosure.
The SlimLine ACUs offer an economical answer for many applications and feature wide temperature and humidity control options, with remote sensing at the load, if required. Compressor cooling is used for –30⁰C (single-stage) and –60⁰C (cascade) models and liquid nitrogen (LN2) cooling for the –80⁰C model.
The Sharetree SIMPLEtouch touch-screen programmer is now standard on all models. This simplifies the operator interface and enables complex profiles to be programmed, data logged, and displayed graphically. (See the separate SIMPLEtouch brochure).
Interface options
The standard interface to the custom enclosure is by means of flexible insulated hoses. An alternative Direct Connection arrangement is possible with some enclosures (see above). The inlet and outlet vents are ported from the bottom of the ACU directly into the custom enclosure to give the maximum possible airflow and even better control.

- Powerful thermal control of custom enclosures
- Wide temperature range (+250 to –60°C)
- Humidity option
- SIMPLEtouch programmer
- 2-stage temperature sensing
- Flexible insulated hoses
- Direct Connection option
- Integral plant

Sharetree Typhoon Air Conditioning Units (ACUs) are specifically designed for re-circulating conditioned air through a variety of custom built product enclosures, or directly to products. ACUs are used where a standard test chamber cannot easily be fitted around the product. Custom designed product enclosures can also be supplied if required.
These versatile ACUs feature wide temperature and humidity control options, with 2-stage temperature sensing for accurate control.
