 Vortex
Tubes from Pelmar Engineering
Vortec Vortex Tubes are an effective, low cost solution
to a wide variety of industrial spot and process cooling
needs. With no moving parts, Vortex Tubes spin compressed
air to separate the air into cold and hot air streams.
While French physicist Georges Ranque is credited with
inventing the vortex tube in 1930, ITW Vortec was the
first company to develop and apply this phenomenon into
practical and effective cooling solutions for industrial
use.

 "Minitwist"
- MTFC - Automatic Self-Cleaning Filtration System
“Minitwist” Automatic Filtration System
Model MTFC is a fully automatic, self-cleaning filtration
system for flows of 0 - 100 US GPM (23M3/H).
It removes dirt as fine as 20 micron, and uses a very
small amount of water during cleaning process. In filtration
mode, flow is from bottom of filter to inside of screen,
and out. During cleaning mode, rotating nozzles collect
dirt removed from screen by reverse flow, and send it
out through top of filter. Backwash process takes only
5 seconds.

 Vortex
A/C™ - Vortex Panel Cooler from Pelmar Engineering
Avoid any downtime, with the most affordable, reliable,
and easiest to install thermal protection product available
for electrical enclosures!
Just as quiet as an air conditioner (about 62 dBA), the
Vortex A/C™ noise level is 73% less than other conventional,
vortex type cabinet panel coolers. When the thermostatically-controlled
Vortex A/C™ is operating, the decibel level is about
the same as normal human conversation!
This next generation, Vortex Panel Cooler features an
integral mechanical thermostat to conserve energy and
maintain enclosure temperatures within a range of 80°
to 90°F. Requiring only a compressed air supply to operate,
the UL listed Vortex A/C™ quickly installs in a 1.5"
knockout hole to keep electrical control panels cool,
clean and protected.

Multi-Spine Disc Filter from Pelmar Engineering
Filtration Process
Inlet opens allowing a flow of water from the inlet manifold
into the filter, through the 5 elements of filtration,
to the outlet manifold and out to the field.
Backflush Process
Inlet is closed. Drain port opens allowing clean water
to flow from the outlet manifold in the opposite direction
into the filter. The discs are cleaned, particles are
flushed out from the filter through the drain manifold.

 Flow
Control Valve from Pelmar Engineering
The Model 770 Rate of Flow Control Valve is an automatic
control valve designed to maintain a constant pre-set
rate of flow regardless of changing system pressures and
demand. It is a pilot controlled, hydraulically operated,
diaphragm actuated globe valve in either the oblique (Y)
or angle pattern design.
Valve differential pressure powers the diaphragm actuator
open or closed. The lower control chamber is connected
through a fixed orifice to the downstream pressure, which
serves to cushion the closing of the valve. The upper
control chamber, which operates on a two-way control principle,
has varying pressure produced by the rate of flow pilot
and the pilot's internal upstream restriction needle valve.
