ZDHHT Series
High Inlet Temperature Refrigerated Air Dryers
Clean, dry compressed air is as vitally important to a small
manufacturing company as it is to the largest of production facilities.
Parker Airtek has designed a dedicated line of high inlet temperature
refrigerated dryers for temperatures up to 200°F (93°C). The ZDHHT
High Inlet Temperature Refrigerated Air Dryer eliminates the need for a
separate aftercooler, moisture separator and particulate lter. It is ideal
for body shops, paint booths or wherever a high inlet air temperature
dryer is required.
With its advanced 5 in 1 drying system, the need for additional piping
and separate aftercooler is eliminated in existing applications resulting in
lower pressure drop thereby saving you money. Incorporated within each
ZDHHT dryer is an aftercooler, 3.0 micron lter, condensate separator,
precooler/reheater and evaporator.

Features & Benefits:
• R134a environmentally friendly refrigerant with no
planned phase out date.
• Energy efficient, low running costs. Air to air heat
exchanger reduces overall size of refrigeration circuit
by up to 60%. Zero air loss float drain saves air.
Saving Air - Saves Energy - Saves Money
• No condensation on downstream piping. Air to air heat
exchanger raises outlet air temperature eliminating
condensation that can occur on chilled piping in humid
conditions.
• Eliminates need for separate aftercooler, pre-filter and
moisture separator. These components are already
built into the dryer, offering an all-in-one, easy to install
package.
• Suited for placement after reciprocating type air
compressor when clean, dry air is required.
