Compressed air treatment

Air quality control is the key to a healthy, well-controlled industrial process. For almost 40 years, we have applied our expertise to support the sustainability of your industry by providing drying and filtration solutions tailored to the most demanding requirements.

Low-pressure (<16 bar) cycling refrigerated air dryers

30 m³/h (0,5 m3/min)  > 3160 m³/h (52,6 m3/min)
Low-pressure (<16 bar) cycling refrigerated air dryers

Discover the power of MASTERIA dryers, engineered with thermal mass refrigeration technology to deliver reliable and energy-efficient compressed air drying. Our patented 3-in-1 heat exchanger ensures maximum performance, with counter-flow transfer across the entire surface for unbeatable efficiency.

Equipped with next-generation DTM (Dual Transfer Mode), MASTERIA dryers guarantee optimal heat exchange and consistent performance. The combination of a multi-tube pre-cooler, a direct air/refrigerant exchanger immersed in a thermal mass, and an integrated moisture separator ensures a stable +3°C pressure dew point in all operating conditions.

With flow capacities from 30 m³/h up to 3160 m³/h, our dryers deliver air quality that meets ISO 8573.1-2010, Class 3 humidity standards, giving you peace of mind, process protection, and long-term reliability.

Caractéristiques techniques

R134a Refrigerant R407c Refrigerant Cooling Refrigeration circuit 1 Indoor use Scroll compressor Multi-tube exchanger

Thermal mass heat exchanger

This patented heat exchanger, the result of CTA research and development, offers great energy savings thanks to its pre-exchanger/saver (from MPE-N 010), its low pressure drop and its high-performance separator. Its DTM technology ensures that the compressed air is not polluted by the refrigerant and guarantees dry, high-quality compressed air in all circumstances.

Refrigeration circuit

It includes all the safety features as standard in order to prevent faults from being generated by misuse. The purpose of these devices is to protect the refrigeration air dryer, but above all to ensure that it functions properly and that the user's process is maintained.

Compressor

Hermetic refrigeration compressors (piston, rotary, scroll) that provide adequate cooling to maintain the dew point under all conditions of use

Controller

The controller is standard on the first models and is designed to optimise the operation of the dryer with a dew point display, condensate drain control and correct operation of the refrigeration circuit. In addition, it allows the reporting of all alarms and malfunctions on the dryer as well as the reminder of maintenance deadlines.

Plug and Play product

Ready to use thermal mass refrigeration dryer with all components directly integrated and allowing easy operation. Masteria dryers are supplied with a power cable, which allows commissioning without having to open the dryer.

Low energy costs

High performance design through its 3-in-1 exchanger which ensures an extremely low pressure drop of 0.15 bar at the expressed nominal flow rate. When the dryer is in partial load, the refrigerant within the exchanger gives up the unused cold to the dry thermal mass that occupies the gaps between the fins and the heat exchanger tubes. The cold is then returned as required to the copper pipes through which the compressed air flows. The refrigeration compressor and fan can therefore be left idle for a long time to save energy. Take advantage of our energy saving calculation tool to find out the energy benefit of your system.

Simplified maintenance

Easy access from the top and side panels of the unit allows optimum maintenance of the dryer. The refrigeration design of Masteria dryers ensures direct access to all components. Technical diagnosis is facilitated by the presence of pressure taps within the refrigeration circuit, as well as the presence of a low pressure gauge on the front panel.

Guaranteed performance

Manufactured and tested in our factories and meeting the ISO8573.1-2010 standard, class 4 humidity, our dryers allow for optimal use over time. The digital controller, guaranteeing correct use and an accurate pressure dew point, ensures that the process downstream of the dryer is protected.

Optimised air circulation

The fan mounted directly in its own housing on the condenser allows for optimum efficiency of the available cooling capacity even at high ambient temperatures.

Record durability and high strength

Its reinforced body, painted in baked epoxy, ensures a long life even in the most corrosive and dusty environments. Its high efficiency condenser, equipped with robust fins, swept by the air without any obstacle allows the possibility of a cleaning and a great behaviour in time.
