As one of the worlds leading manufacturers
of compressed air purification equipment, Donaldson
has built a comprehensive engineering, manufacturing, and customer support network to meet the most
demanding applications. With over 30 years of expertise in compressed air filtration and separation technologies,
Donaldson manufactures a complete line of drying and filtration equipment in an innovative design focused on
energy efficient operation and reliable performance. Our refrigerated dryer offering is split into two distinct
ranges: Donaldson offers a non-cycling and a cycling range of refrigerated dryers to meet all application
requirements.
Cycling range*
RFC Series (200 - 650 scfm)
DVF Series (800 - 2,000 scfm)
RTM Series (2,500 - 30,000 scfm)
Our non-cycling range
is focused on reliable, constant dew point performance in all flow conditions.
With its excellent heat transfer coefficients and low pressure drop, these dryers will outperform
the competition in protecting your compressed air system, machinery and tools; and will improve your
manufacturing processes.
Through optimization of the critical dryer components heat exchanger, separator and condensate removal
the Donaldson engineers developed a system that ensures highest performance at full- and partial-load
conditions to protect your application at all times.
Donaldson's high-efficiency
cycling range
is designed
to automatically cycle ON/OFF depending on the actual
load conditions.
Ozone-safe, 100% chlorine free, R-134a
refrigerant as standard
Donaldson uses R-134a refrigerant in all refrigerated
compressed air dryers as standard. R-134a has become
the industrys choice as the preferred refrigerant because
of its ozone depletion factor of 0.0 and low global warming
potential. R-134a is a one-blend refrigerant and, therefore,
consistent in performance (no temperature glide) and
easy to service (no mixture of different refrigerants).
All Donaldson dryers are designed to give our customers the best value available in the industry reliable
performance to CAGI ADF 100 specification while consuming the lowest amount of energy possible.

Non-cycling range
VF Compact Series (10 - 40 scfm)
VF Series (50 - 2,000 scfm)
AR Series (2,500 - 10,000 scfm) Non-Cycling Refrigerated Compressed Air Dryers Lightweight & compact. Precooling and reheating of compressed air for
high efficiency and low energy consumption. Patented Variable Flow high-efficiency
anonized aluminum heat exchanger utilizing
3-step process of Impaction, Brownian Motion,
and Surface Tension to achieve consistent
dew point at varying flow conditions. Heat exchanger includes multi-stage separator
with removal (cleanable) stainless steel
mist eliminator. Environmentally friendly refrigerant R-134a
ensures reliable operation in high ambient
overload conditions.
Donaldson VF Series dryers
offer highest
efficiencies at varying flow conditions in a lightweight,
compact design. No other dryer in the industry can
offer the efficiency ratings achieved by the VF Series
dryers in variable flow operation.
VF Series dryers are built with the patented Variable
Flow heat exchanger, which allows for desired dew
point performance regardless of flow variations.

separators lose performance as compressed airflow
velocity increases or decreases substantially around
the nominal design point.
The VF Series high efficiency heat exchanger utilizes
a three-step process to thoroughly remove condensed
moisture from the chilled compressed air. This
process provides a separation efficiency in excess of
98% throughout the dryer's entire flow range

** Capacity rated in accordance with ISO 7183 @ 7 bar (101.5 psig), 35°C (95°F) inlet, 25°C (77°F) ambient and a PDP of 3°C (37.4°F).
Ambient air temperature: 35°-120°F, inlet air temperature: 140°F max., operating pressure: 200 psig max.
Hot, saturated compressed air is first
precooled by exiting cold air in the air-to-air
heat exchanger. The precooled air then enters
the evaporator where it is cooled to its final
dew point. The mixture of cold air and
condensation flows into the three-stage
separator/
mist eliminator where liquids and
contaminants are reliably removed and ejected
from the system via a programmable timer
drain valve. The cold air is then reheated by the
incoming hot air before leaving the dryer.

Warm gas enters the RECUPERATION
SECTION and exchanges heat with
the cooler leaving gas.
The gas then proceeds to the DRYER
SECTION and is cooled using
refrigeration to a designed dew point.
The gas then proceeds through a
specially designed MOISTURE
SEPARATOR SECTION, where
condensate drops out into the bottom
of the separator.
The gas then proceeds back through
the RECUPERATOR SECTION where
it is heated up by the incoming warm
gas.

To protect your investment, we recommend that you
install a high performance prefilter directly in front of
your dryer. By doing this, you will not only ensure
trouble-free operation for years to come, but also
guarantee that the dryer will operate at its highest
efficiency rating thro
