HPDry

HPDry 

Refrigeration air dryers

Air flow 0,7 – 119 m³/min

The HPDry has been studied specifically for high pressure drying requirements (e.g. the production of PET bottles). The extremely strong construction with shell and tube heat exchangers with stainless steel pipes, ensures safe and continuous operation in any conditions.
HPDry is an energy saving dryer as it exploits the operational advantages of the thermal storage principle: a hydraulic vessel on the machine accumulates cold, acting as a thermal storage. This allows the dryer to automatically adapt to the air flow and ambient conditions, ensuring energy savings, which at partial loads can typically vary from 30 to 80%.
All HPDry models are made up from a chiller used to cool the compressed air passing through the gas/water shell and tube heat exchanger, allowing the moisture to be removed.

Benefits
High energy saving thanks to the thermal storage operation (no hot gas by-pass valve necessary)
Stainless steel corrosion-proof heat exchanger pipes
Stainless steel double demister separator
Constant dew point in all operating conditions thanks to the inertial storage tank
Quick and easy installation
Maximum reliability
Low environmental impact and reduced carbon dioxide emissions thanks to the use of environmentally friendly refrigerant R407C and the use of top quality materials that can be recycled.
No need to switch on and off: HPDry switches on and off automatically.
