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.

Air Conditioning Units
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.
The systems are fitted with our SIMPLEtouch touchscreen programmer to simplify the operator interface and enable complex profiles to be programmed, data logged, and displayed graphically (see brochure)

Key Advantages
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.
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
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).
The Typhoon ACUs with mechanical cooling, can also be supplied in a High Temperature version (+250°C) using our Evaporation Protection System.
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.
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.
In addition to providing standard and custom ACUs, Sharetree can also combined them with Custom Enclosures. See Custom Enclosures on our website for details.
