The CD3 close control system is suitable for computer rooms, laboratories and standards rooms where the close control of temperature and humidity is extremely important. The units are designed to give the specifier maximum flexibility, the engineer easy access for installation and maintenance and the end user ease of operation.

The CD3 units offer large duties from a small footprint and meets the majority of todays close control needs air conditioning in both upflow and downflow models using R407C refrigerant. Single or twin circuit indoor units can be attached to the appropriate outdoor condensing unit(s). CD3 upflow package units are manufactured to a pre-determined specification incorporating cooling, heating, humidification and dehumidification facilities.

The units are available in four capacities and three cabinet sizes, manufactured in a powder-painted steel construction with an easy clean corrosion resistant drain tray and have a washable filter, a de-ice therostat, a totally enclosed electrics panel and a choice of airflow configurations.
