DOMNICK hunter has released the Pneudri MX and MPX air drying systems.

They are electronically controlled and have a modular construction that allows for rapid expansion of systems as industrial plants expand. They also provide 100% standby drying capacity at a fraction of the cost of larger conventional systems.

The aluminium-formed towers are half the size and weight of traditional twin tower designs, taking up less floor space and making installation easier. The heatless dryers will deliver air at -40ºC pressure dewpoint as standard, in accordance with ISO 8573.1 :2001 class 3.2.1.

When combined with filters, the dryers can achieve Air Quality Class 1.2.1 and 1.1.1. Flow rates of individual units extend from 408Nm3/h to 2815Nm3/h.

The energy-efficient low differential pressure design and reliable air management system provide cost-effective operation, with the option of fitting domnick hunter's Dewpoint Dependent Switching (DDS) system. The DDS system can achieve energy savings of over 90% during the process of drying compressed air to remove impurities that can adversely affect tools, processes and product quality.

Long life pneumatic cylinder valves provide reliable switching. High quality Snowstorm desiccant filling ensures stable dewpoint performance, consistent airflow and long desiccant life with minimum purge requirements.

Quiet operation results from reduced blow-down noise. The modular design eliminates the need for complex valves and interconnecting piping used in conventional twin-tower designs.

The multibanking of dryers enables individual banks of dryers to be isolated for routine maintenance work or to provide an energy-efficient decrease in air capacity, such as for a night shift. Modularity ensures there is no interruption to supplies of clean, dry air.

Electronic control options include SMART controllers, the provide system status display, service indication and, for DDS operation, a dewpoint display. The monitoring and control system provides full system status display for the air network, including dewpoint, temperature and pressure. The microprocessor-controlled system can be configured to monitor individual plant requirements with individually set warnings, fault alarms and area shutdowns.
