• Low pressure drop across the dryer
• Modular construction of exchanger
• Lower power consumption, even in variable conditions stable dew point control irrespective of flow
• Combined unit providing improved performance and reliability

The range of ACT (aluminium cooling technology) dryers possess many benefits over conventional dryers. The modular construction of the air/air heat exchanger, refrigerant/air heat exchanger and separator into one single unit, not only improves reliability but also allows for a far lower pressure drop across the dryer when compared to other systems. This results in significantly lower power consumption and a more stable dew point control.

The ALU-DRY modular heat exchanger in more detail.

The air/air heat exchanger and the air/refrigerant heat exchanger are combined with the demister type condensate separator into one vertical unit. The unique (patented) design reduces the number of pipe connections needed, whilst the modular and vertical arrangement improves the effectiveness of the drying process.
(A) - The counter flow arrangement to the air passages within the air/air heat exchanger ensures maximum heat transfer efficiency providing superior performance.(B) -The generous size of the air/refrigerant heat exchanger along with the further employment of counter flow techniques to the gas flow stream allows for a complete and efficient evaporation of the refrigerant ensuring that no liquid can be returned to the refrigeration compressor improving efficiency and reliability still further.(C) - The high efficiency condensate separator is located in the perfect position at the bottom of the vertical heat exchanger arrangement. The separator labyrinth is generously sized and employs coalescence in order to achieve a high degree of moisture separation.(D) - The generously sized separator allows for the correct functioning of the dryer in situations of extreme humidity.(E) - The larger cross sectional area of the flow channels within the heat exchanger reduces the velocity of the compressed air flow, resulting in a much lower pressure drop and subsequently lowers power consumption.

Technical Specification:

Control panel: operation of the dryer is automatically controlled and monitored by the digital controller and thermostat. The sophisticated DMC200 micro-processor based controller is fitted as standard to models ACT900 and above and is available as an option to all other models.

Standard hot gas by-pass valve: new and unique hot gas by-pass valve prevents the formation of ice inside the evaporator irrespective of load or ambient conditions. The valve is adjusted during final testing with no further adjustments required throughout the life of the dryer. The same valve is fitted to all ACT dryers for uniformity.

Condensate drain: dryers are fitted with a simply adjusted automatic drain valve for the discharge of condensate... Both the frequency and duration of the drain process can be easily adjusted to suit the ideal conditions present. An optional zero loss sensor controlled drain can be fitted as a low cost option to all our dryers. The sensors within this drain allow the operation of the discharge only when the drain is full. The condensate can then be removed with no loss of compressed air, providing energy savings with no need for adjustment during use, even in varying load conditions.

Condenser: generous sizing of the condenser ensures the perfect operation of the refrigeration circuit with the ability to accommodate severe changes to ambient conditions when required. The condenser is ideally situated within the cabinet to allow ease of access for cleaning.
