High Pressure Non Cycling Refrigeration Dryer Gardner Denver GDD110F HP45

Description High Pressure Non Cycling Refrigeration Dryer Gardner Denver GDD110F HP45

Gardner Denver GDDF HP45 high-pressure refrigeration dryers safe and constant quality, dry compressed air for various demanding environments such as PET bottle blowing, water jet cuts and aeronautical valves, in ambient temperatures of up to 50°C.

Delivering consistent dew point control of +3°C for reliable and dry compressed air, this rangeof ten robust, compact and space-saving dryers provide maximum reliability at flow rates of between 88m³/h to 1200m³/h (at a nominal pressure of 40 barg).

The easy-to-use controller automatically manages dryer operation while monitoring critical parameters to deliver optimal air treatment efficiency.

Fully integrated three in one stainless steel heat exchangers offer reliability and long life. At the same time, energy efficiency is increased by 10% over previous models, and CO₂  footprint is reduced with the use of R513A or R407C refrigerant.

How the refrigerated dryer works
Utilizing a closed refrigeration cycle with eco-friendly refrigerant, the dryer cools the air to condense and extract moisture. Delivers a pressure dew point of +3 °C (ISO 8573-1:2010 Class 4).

Step-by-Step Process:

1. Compressed Air Intake Moisture-laden compressed air enters the dryer directly from the compressor.

2. Pre-Cooling via Heat Exchanger Incoming warm air is initially cooled by exchanging heat with already dried, cooler outgoing air. This increases overall efficiency.

3. Refrigeration Cooling Cycle The air then enters the refrigeration unit, where it is chilled using the eco-friendly refrigerant. Lowering the temperature causes water vapor in the air to condense into liquid.

4. Moisture Separation & Drainage Condensate is collected by an integrated separator and discharged using an intelligent no-loss electronic drain, minimizing air loss.

5. Reheating Before Exit Before exiting, the air is reheated via the heat exchanger to prevent condensation and corrosion in downstream piping.

6. Smart Control System A programmable control panel regulates fan speed and monitors dew point, temperature, freeze prevention, and alarms — ensuring optimal performance and avoiding icing or faults.
