Air Conditioning Units – Heavy Duty

SKU: ACU-T Category:


Air Conditioning Units (ACUs) – Heavy Duty 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 Air Conditioning Units feature wide temperature and humidity control options, with remote sensing at the load if required. The systems are microprocessor controlled, with the option of our Touch Screen Programmer to simplify the operator interface and enable complex profiles to be programmed, data logged, and displayed graphically.
