Gravity
is a powerful force. The T Series Heatless air dryer has been specifically designed to
fully utilize the force of gravity to optimize dryer performance. With a wet air inlet at the bottom of the dryer,
water and oil
droplets are concentrated at the bottom of the desiccant bed. During downflow depressurization and regeneration, the power of
gravity helps pull the water and oil out of the dryer.
Only
two types of switching valves are used. All valves 2” and smaller are Y
angled globe valves with a
diaphragm actuator. This design permits higher flows at lower pressure drops than any
comparable valve. A separate chamber protects the diaphragm without disrupting
service or removing the valve from the dryer.
Preformed,
stress relieved diaphragms minimize fatigue, maximize valve
responsiveness, and diaphragm life. Standard valve materials are cast iron body with stainless steel
and brass internals.
Valves
3” and larger are high performance butterfly valves. A patented axially pliant seat flexes against the sealing edge of
the disc when the valve is closed. This design assures bubble tight shutoff. Made of PTFE with a unique pliant membrane, the bi-directional,
self and pressure activated seat returns to it original shape with every
opening of the valve because the pliant membrane causes constant
restorative forces to act on the seat member. The eccentrically mounted disc is offset, which provides for an
uninterrupted, 360°
seal.
Check
valves are one of the biggest problems with competitive heatless dryers. Our check valves have several unique features to increase
performance and reliability. Check valves through 2” are a spring loaded ball cone style
valve. This
design has the advantages of bubble tight shutoff and does not require
radial alignment. The straight through design is streamlined for a minimum change in
velocity and also minimizes pressure drop.
The spring loading allows for fast
sealing. The valve body is
bronze, the ball is glass filled TFE with a 316 stainless steel spring.
Valves 3” and larger are double
door spring checks. This
design has a cast iron body with aluminum internals. The wafer has a silicone seal for outstanding durability and
performance. 304 stainless
steel springs provide fast sealing.
Exclusive five year limited warranty provides
real peace of mind. Minimum
periodic maintenance keeps the dryer operating like new and keeps the
warranty in effect for up to five years.

Solenoid valves have aluminum
bodies with stainless steel internals. The orifice seat is machined as part of the body, guaranteeing
leak-proof internal structure and has a buna seal for additional
protection. The low wattage
coil results in less current drain and is rated for NEMA 4 and by UL.
Upflow drying design allows the
dryer to operate under adverse, real world conditions. Slugs of water or oil stay on the bottom of the bed and are
easier to regenerate off. Our
unique standpipe design prevents desiccant fluidization, even under
upset conditions.
Non-lubricated switching valves are
proven reliable. Only 4
switching valves, each controlled by an independent solenoid. Very few moving parts, very simple design. Low pressure drop, soft seats, easy to maintain.
Only 2 check valves. Enhanced reliability and improved performance.
ASME
Code pressure vessels are
standard.
Pressure gauge on each tower.
Relief valves on each tower.
Fixed
orifice purge rate, calibrated for your flow. Easy to change, impossible to go out of
adjustment or shut-off.
Afterfilter included on Model T-75
(375 SCFM and smaller). Prefilters
and afterfilters mounted on dryer for nominal charge on all other
models.
The mufflers used have been proven
by years of use in thousands of dryers. The muffler design meets all of the requirements for OSHA
regarding noise control. The
muffler is constructed with an expansion chamber completely free of
obstructions from which the exhaust air, at reduced velocity is softly
dispersed through the openings of the perforated cylinder wall of the
muffler; free of noise and providing complete protection to personnel
from injurious air blast. Constructed
entirely of corrosion resistant material for maintenance-free
performance.
The optional
Energy Management System (EMS), allows the dryer to operate on dewpoint
switching instead of time, reducing energy consumption, while improving
performance and reliability.
EMS probes inserted into the towers
are protected by stainless steel desiccant retainers. The probes are not in direct contact with the desiccant. By accurately measuring relative humidity in both the drying and
regenerating tower, the EMS delivers optimum performance and energy
efficiency.
