CLEAN and dry compressed air is essential for any modern manufacturing facility. Contamination in air lines increases production line downtime, as well as tool and pneumatics maintenance costs. Apart from the direct cost of parts and labour, the loss of production adds to increasing unit costs caused by sub-standard compressed air quality.
The CDK range of refrigeration air dryers manufactured in Thailand to international standards is distributed in South Africa by Artic Driers. The range provides a consistent compressed air dew-point over the full range of operating conditions and air flows.
Artic Driers MD Paul Cockfield says, “Oil-free air compressors generate condensates with low pH values that soon corrode mild steel pipework. The CDK range overcomes this problem with the use of stainless steel. Any part of the CDK series that is in contact with wet, compressed air is manufactured in stainless steel. The larger models of the CDK dryer range are fitted with multiple heat exchangers piped in parallel. The inlet and outlet pipe galleries to these exchangers are constructed in stainless steel. This feature makes the range a perfect long-term partner for oil-free compressors.”
The comprehensive instrumentation built into CDK dryers enables the control and monitoring of all parameters, such as inlet compressed air temperature, dew-point temperature, air/gas temperatures, and ambient temperature.
CDK dryers restart automatically on resumption of power via an adjustable restart timer. The dew-point set point is also adjustable by the controller. These features are some of many that are password protected to prevent unauthorised changes to the dryer’s settings.
“Artic Driers provides a huge range of imported and locally-produced air filter housings that contain different grades of filter elements to suit any requirements,” says Cockfield.
“Locally-produced filter casings are SANS 347 coded and plated, and are coated to resist interior and exterior corrosion. All the element fixings are stainless steel. We carry stock of casings with capacities of up to 150 m³/min at 7 bar.”
A broad range of instrumentation focused on compressed air and gas volume, pressure, power consumption and compressed air quality, is available for monitoring. The S551 mobile data logger from SUTO iTEC provides instant access to all the parameters of flow, pressure, dew-point, temperature, power consumption, oil vapour content as well as particle content.
Artic Driers offer ultrasonic leak detection solutions that are difficult to match. The reporting software provides immediate data on the cost of compressed air wastage, giving volume of air wasted to atmosphere. Reports are provided in PDF and Excel formats that allow the customer to plan rectification programmes.
Leaders in the air treatment business for over three decades, Artic Driers has an exceptional range of equipment along with in-house manufacturing capabilities, making it the go-to-company for compressed air solutions.
