Purpose Nontoxic
High Quality Heat Transfer Fluid
AN
ECONOMICAL GENERAL PURPOSE FLUID FOR OPEN AND
CLOSED LOOP LIQUID PHASE HEATING SYSTEMS.
MultiTherm
IG-2 ®
is
a Nontoxic High Quality Heat Transfer Fluid for
use in closed loop, liquid phase heating systems
up to 600°F and in open systems up to 400°F.
MultiTherm IG-2 ®
has been successfully used in a variety
of chemical process industry, it is used
in central hot oil systems for heating all types
of process equipment. In asphalt storage facilities,
the fluid is used for line tracing and tank heating.
In industries laundries MultiTherm
IG-2 ® provides higher throughput
with a great degree of safety in flat work ironies.
DURABLE
Open Systems
Oxidation and fluid boil-off are major problems
when using organic heat transfer fluids in hot
open systems. Oxidation produces organic acids,
which react and create deposits. The rate of boil-off
an oxidation are dependent of the fluid vapor
pressure. The higher the vapor pressure, the greater
rate of oxidation and fluid boil-off. MultiTherm
IG-2 ® has exceptionally low vapor
pressure, and as a result its service life is
significantly longer under these severe conditions.
Closed Loop Systems
Closed loop, liquid phase heat transfer systems
often operate for extended periods of time with
little or no problems. However, equipment malfunctions
such as circulating pump failures, bypass valve
malfunctions, and cracked heater tubes do occur
and can put extra stress on the heat transfer
fluid. If the fluid has been in service for a
period of time, and especially if it has been
exposed to air at high temperature, these malfunctions
can cause rapid degradation and require immediate
replacement to prevent further equipment problems.
MultiTherm IG-2 ®
is a highly refined product with proven
resistance to oxidation and thermal breakdown.
It can take the stress without requiring premature
replacement.
HIGH FLASH POINT
In certain applications, local, state or
federal regulations may require that the thermal
fluid system operate below the fluid flash point.
This can result in the need for greater heat transfer
surface area (more expensive equipment) to achieve
required heat loads. MultiTherm
IG-2 ® has one of the highest
flash points of any heat transfer fluid (440°F
/ 227°C) which provides maximum system efficiency
under these conditions.
LOWER COSTS
Reduced Equipment Costs
Incorporating MultiTherm
IG-2 ® in a system during
the design phase can reduce equipment costs. Its
extremely low vapor pressure eliminates the need
for pressurized expansion tanks to prevent pump
cavitation and can allow specification of less
expensive, low pressure piping and process equipment.
VOC emissions are not normally a problem with
MultiTherm IG-2 ®
since system pressures are low and fluid
vapor pressure is not significant.
Reduced Maintenance Costs
MultiTherm IG-2
® is based on a parrafinic oil
that coats all system surfaces with a protective
fluid film. This film provides outstanding lubricity
for moving parts and also helps protect components
from corrosion.
