DRYPOINT® RA-eco
Proven system, used everywhere
The DRYPOINT RA refrigeration dryer is the standard solution and therefore the first choice for applications with stable operating conditions and constant pressure dew points of +3°C. Thanks to a wide choice of models, we can always offer you the right solution for your requirements. Our refrigeration dryers are characterised by reliable drying, minimal compressed air loss and low energy consumption. The proven design of the DRYPOINT RA provides not only maximum functionality but also reliable and cost-effective operation.

The advantages of the DRYPOINT RA
Refrigeration dryers are used everywhere and are now state of the art in compressed air networks. They are the most economical method of drying compressed air: cooling the compressed air causes the water vapour it carries to condense into water, which is then drained off. With fluctuating flow rates, the DRYPOINT RA eco lets you save considerable energy thanks to its intelligent control. For all applications where stable conditions matter, the DRYPOINT RA offers the most efficient solution.
All DRYPOINT RA refrigeration dryers achieve optimum heat exchange through the counter-flow principle along the entire path. The compressed air flows downwards along the entire path inside the heat exchanger. This takes place without unfavourable diversions, resulting in very low compressed air loss.
Convincingly efficient with minimal pressure loss
A high pressure drop in the refrigeration dryer has to be compensated for by increased compressor output and the associated additional energy demand. The result is unnecessary energy consumption and significantly higher operating costs. This is why the pressure drop in DRYPOINT RA refrigeration dryers has been reduced to an absolute minimum. Key elements are the flow-optimised heat exchanger, a demister for reliable separation and generously sized components, which ensure a low pressure drop of 0.16 bar on average – at full load.
New in the range – R513A refrigerant
DRYPOINT RA refrigeration dryers are also available with the environmentally and ozone-friendly refrigerant R513A, which offers you the following advantages:
- Economical standard solution combined with low global warming potential
- First choice for applications with stable operating conditions and constant pressure dew points of + 3 °C
- Compliant with the requirements of the F-gas regulation
economical: DRYPOINT® RA eco
The new generation of refrigeration dryers combines economic aims with ecological responsibility. With our energy-saving dryers from the DRYPOINT RA eco series, cost-effectiveness has been redefined: the sum of the technical features has significantly reduced pressure loss, compressed air loss and power consumption. With fluctuating compressed air consumption, intelligent control saves energy by optimally matching the dryer’s output to the compressed air demand. The DRYPOINT RA eco builds on what has proven itself and extends it with an intelligent energy concept.
The biggest savings come from the energy we do not use. The DRYPOINT RA eco refrigeration dryer series continues the already successful concept of the DRYPOINT RA with low pressure loss, optimal heat exchanger design and BEKOMAT . On top of this, we have added two new control concepts for the different sizes, which adapt the drying capacity directly to demand and thus considerably reduce energy consumption.
proven system, intelligently controlled
Refrigeration dryers are often designed for the toughest operating conditions – the benchmark being summer operation with high inlet and ambient temperatures. As a result, the dryer is oversized most of the time and rarely runs at constant full load. The DRYPOINT RA eco refrigeration dryer stands for optimised resource efficiency: it is used wherever compressed air systems and products must be reliably protected against condensate and contamination. Drying is achieved by cooling the air. The resulting condensate is drained efficiently and without compressed air loss by the BEKOMAT . Reheating reduces the relative humidity of the dried air to below 30%. The energy consumed is matched to the drying capacity required. This process saves energy costs and protects the environment.
Frequently asked questions
Which applications is the DRYPOINT RA suitable for?
It is the standard solution for applications with stable operating conditions and constant pressure dew points of +3 °C. Thanks to a wide choice of models, there is a suitable unit for many requirements.
How does a refrigeration dryer dry compressed air?
It cools the compressed air so that the water vapour it carries condenses into water, which is drained off. Subsequent reheating lowers the relative humidity of the dried air to below 30 %.
What is the difference between the DRYPOINT RA eco and the DRYPOINT RA?
The RA eco builds on the RA and adds intelligent control. It matches the drying capacity to the compressed air demand and thus saves considerable energy with fluctuating flow rates.
How high is the pressure drop?
At full load, 0.16 bar on average. This is achieved by the flow-optimised counter-flow heat exchanger, a demister and generously sized components.
Why is a low pressure drop important?
Every pressure drop in the dryer has to be compensated for by more compressor output. This wastes energy and increases operating costs.
Is compressed air lost when draining the condensate?
No. The condensate is drained via the BEKOMAT without any compressed air loss.
Which refrigerant is used?
DRYPOINT RA refrigeration dryers are also available with the ozone-friendly refrigerant R513A. It has a low global warming potential and meets the requirements of the F-gas regulation.
Is the eco version worthwhile if my dryer rarely runs at full load?
Yes, especially then. Refrigeration dryers are usually designed for summer operation and are therefore oversized most of the time. The RA eco matches the energy consumed to the drying capacity required.
Who can help me with sizing?
We can. The right size depends on flow rate, compressed air inlet temperature and ambient temperature. Call us or write to us.
Which refrigeration dryer suits your application?
The sizing of the right DRYPOINT RA refrigeration dryer varies depending on flow rate, compressed air inlet temperature and ambient temperature. Let us advise you to find the optimum model for your needs.
