 Heat
Transfer Equipment
Looking for heat
transfer equipment from chillers to cooling towers?
A piece of heat
transfer equipment is any device designed for the efficient transfer
of heat from one object to another object, i.e., ususally from one
fluid to another. In a chiller, these two fluids are separated from
another so that they never mix. Heat exchangers are used in chillers
to facilitate the movement of heat energy generated by the hydraulic
systems in the injection molding process. Our chillers are also
used for heat transfer in refrigeration, air conditioning, space
heating, power production and chemical processing.
What
is Heat Transfer Equipment?
Heat transfer is the movement of heat energy from one medium to
another without mixing the two. Since heat energy moves naturally
from a hot to a colder body, heat transfer equipment usually involves
transfering heat energy from one fluid or gas to another without
mixing the two. When
an object, i.e., a liquid like water, is either warmer or colder
than its surroundings or another object, the transfer of heat energy
occurs in such a way that the body and the surroundings (or another
object) reach equilibrium.
Heat Transfer in Injection Molding
A major component of the injection molding
process is cool water for cooling down the oil in these hydraulic
systems and even the molded parts themselves. If it's too cool,
the oil will thicken causing the valves to operate sluggishly or
not at all. If the oil is too hot, it will degrade into a thin liquid
filled with chunks of additive materials that broke down because
of the heat. These clog passageways and interrupt operation of the
hydraulic mechanisms. The temperature of the oil is controlled by
a heat exchanger inside a chiller. The chiller circulates the oil
over copper (or other highly conductive metal) tubing that weaves
back and forth inside the heat exchanger. The tubing is connected
to a water inlet and the temperature of the oil is monitored. When
the oil is cold, the chiller does not circulate the water in the
tubes. The water absorbs heat from the oil as the oil warms up while
flowing through the hydraulic system. When the oil becomes too hot,
the heat exchanger opens the water inlet valve to allow water to
circulate through the copper tubing. The circulating water draws
heat from the oil until the oil temperature drops to the proper
level. The system then cycles the water off until needed again.
In this way, the heat exchanger can maintain the proper oil temperature
at approximately 120° F, ±5° F (49° C, ±2.7°
C)
Chiller and Tower Water Tank Sets
Our complete line of heat transfer equipment includes pump
tank stations and pumping systems for transporting liquids, i.e.,
water or a water-glycol solution through chilling systems for cooling
the injection molding machines. We supply both chiller
and tower water tank sets for process
cooling. We offer 7 standard models, each with double pumps, baffled
tank and lid. The two pump system has one pump dedicated to the
chiller or chillers to maintain constant water flow required by
the chillers to ensure maximum efficiency and safe operation. The
second pump is dedicated to the process to supply higher flows than
the chillers would normally allow, and higher water pressure required
by the varying process equipment demand.
Chilling Systems
and Cooling Towers
As our signature product, chillers and cooling towers for heat transfer
are what we do the best. Our engineering expertise not only makes
our heat transfer equipment easy to inspect, maintain and
repair, they are easily the most energy efficient and
long lasting equipment on the market. Our cooling systems
are ingenuously designed and
include oversized condensers and stainless steel brazed plate evaporators.
Not only does this mean much longer lasting compressors, but a much
more efficient system. Add a hot gas by-pass, a water
flow switch, a freeze thermostat, non-rusting water
piping, and you have the perfect fit for anyone who has to worry
about cooling reliability and cost effectiveness. All our
models can be delivered immediately from stock or 2 to 4 weeks if
not in stock.
If
you're worried about your chiller breaking down and costing you
money for lost production and costly repairs, our chillers are the
answer you're looking for. Finding a reliable chiller for your injection
molding process is difficult when there are so many low cost imported
chillers overflowing the market. While it is tempting to think that
you are saving money, a low price is often a compromise on reliability
and quality. A low cost chiller might appear to be cheaper, prettier
to look at, with a nice outer shell or cover, but most are not built
to last, are unreliable, easily damaged, and hard to fix. Don't
settle for less than the best. If you're looking for a quality designed
chiller that is durable, reliable, easy to install and service,
then you've come to the right place.
