Hankison HDI-E refrigeration dryer
Maximum energy efficiency for your compressed air system
Hankison HDI-E refrigeration dryers have been specially developed for companies that want to dry their compressed air reliably while reducing energy consumption. Thanks to intelligent cooling technology and innovative heat recovery, the units deliver a constant pressure dew point of 3 °C and ensure dry compressed air even with fluctuating compressed air demand.
Flow rate
54 to 5,400 m³/h
Pressure dew point
3 °C
Refrigerant
R513A
Energy saving
up to 80 %
Intelligent energy technology
Unlike conventional refrigeration dryers, the HDI-E series works with patented two- or three-layer heat exchanger technology and a separate glycol circuit. This allows the refrigerant compressor to pause automatically at low load while the compressed air continues to be dried reliably. This significantly reduces power consumption and extends the service life of the components.

High operational reliability
The HDI-E series relies on durable scroll compressors with few moving parts. Corrosion-resistant materials and comprehensive monitoring of all important operating parameters ensure reliable continuous operation even under demanding industrial conditions.
The modern control panel provides information on the current operating status at all times and supports functions such as:
- Anti-frost protection
- Dew point monitoring
- Temperature and fault messages
- Alarm history
- Optional remote on/off operation
For a wide range of compressed air applications
Hankison HDI-E refrigeration dryers are suitable for almost all industrial compressed air systems and cover flow rates of 54 to 5,400 m³/h. They therefore offer an economical compressed air treatment solution for medium-sized production plants and large industrial facilities alike.
Intelligent energy technology saves up to 80% of energy costs
With its reduced energy demand and the use of the environmentally friendly refrigerant R513A, the HDI-E series helps to cut operating costs while reducing environmental impact. The combination of high efficiency, reliable technology and low maintenance makes the units a cost-effective long-term investment.
Frequently asked questions
